Description

Title of the invention: Composition comprising an absorbent pigment and at least one specific mother-of-pearl based on aluminum oxide AND VARIOUS IRON OXIDES, FOR A SHINY EFFECT AND THE PROCESS FOR IMPLEMENTING IT

[0001] The present invention relates to makeup compositions for human keratinous materials, in particular the lips, comprising at least one non-volatile polar or non-polar hydrocarbon oil, or silicone, at least one pigment with an absorbent effect consisting of a borosilicate coated with several layers of oxides, hydrated oxides or metallic hydroxides based on titanium, tin and iron, and comprising between the layers, at least one spacer layer;at least one first nacre consisting of an aluminium oxide substrate in the form of platelets having an aspect ratio of at least 85, and a coating comprising a layered structure consisting of a first layer composed of hematite and / or goethite and a second layer composed of magnetite, in this sequence, on the substrate, optionally at least one second nacre consisting of aluminium oxide and titanium dioxide, and optionally of tin oxide, as well as a makeup process implementing it.

[0002] Cosmetic compositions intended for application, particularly to the lips, especially for care and / or makeup, have been known for a very long time and come in a wide variety of forms. These compositions can range from fluid, more or less viscous formulations, such as oils and glosses, to solid compositions in the form of a stick, with or without support, pencil-like compositions, or compositions packaged in pots or pans constituting a palette.

[0003] The compositions may also be anhydrous or be in the form of emulsions, direct (oil-in-water) or inverse (water-in-oil).

[0004] Liquid or solid compositions, particularly those intended for makeup and / or lip care, with a rather glossy finish, are generally obtained from mixtures containing relatively high levels of non-volatile oils, often hydrocarbons or silicones, as well as coloring agents such as mother-of-pearl and / or pigments. The effect can be satin or, conversely, excessively glossy, even glittery or with a mirror-like effect.

[0005] In addition, certain nacres, based on metals such as metallic aluminum, which are effective, have a use which is restricted to certain types of cosmetic compositions, in particular anhydrous compositions, for compatibility reasons.

[0006] One of the current trends is to have natural and discreet makeup, with a finish that reflects healthy and hydrated skin. However, it is complex to achieve such a result that gives a "wet" effect, that is neither satiny nor too shiny, and that allows the skin to show through the makeup, thus giving the impression that the skin is hydrated (not dry) and plump.

[0007] The objectives of the present invention are therefore to provide cosmetic compositions that achieve such a result, for a wide range of formulations, anhydrous or otherwise. Such compositions are stable, easy to apply, comfortable, and have little or no stickiness, which remain so once applied.

[0008] These and other objectives are achieved by the present invention, which therefore relates to compositions for the makeup of human keratinous materials, in particular of the lips, comprising: * at least one absorbent pigment comprising a substrate in the form of calcium sodium borosilicate platelets and a coating applied to the substrate, comprising titanium, iron and tin, the coating comprising a) optionally a layer 1 comprising or consisting of at least one tin oxide, tin hydroxide and / or hydrated tin oxide b) a layer 2 comprising at least one metal oxide, metal hydroxide and / or hydrated metal oxide and c) a layer 3 comprising at least one metal oxide, metal hydroxide and / or hydrated metal oxide; at least one of layers 2 and 3 comprising at least two different metal ions, selected from titanium, iron, tin, and mixtures thereof; layers 2 and 3 being interrupted by at least one spacer layer; * at least a first nacre consisting of an aluminium oxide substrate in the form of platelets having an aspect ratio of at least 85, and a coating comprising a layered structure consisting of a first layer composed of hematite and / or goethite and a second layer composed of magnetite, and optionally, another colourless dielectric layer on the magnetite layer, in this sequence, on the substrate; * possibly at least a second nacre made of aluminium oxide and titanium dioxide, and possibly tin oxide; * at least one non-volatile hydrocarbon oil, polar or non-polar, or silicone-based, as well as mixtures thereof.

[0009] It also relates to a process for making up keratinous materials, in particular lips, in which the previously defined composition is applied to said human keratinous materials, and preferably to the lips.

[0010] The present invention makes it possible to obtain a stable composition that is very easily applied to the lips in a precise, homogeneous deposit, the shine of which gives the lips a "wet," plumped appearance. The resulting deposit also provides good comfort.

[0011] These and other advantages of the present invention will become more apparent upon reading the description and examples that follow.

[0012] Note that in the rest of the description, unless otherwise indicated, the bounds indicated for a domain are included in that domain.

[0013] The expressions "at least one" and "several" are used interchangeably.

[0014] In addition, the sum of the quantities of the ingredients of the composition represents 100% by weight, relative to the total weight of the composition. Protocol for shear strength measurement

[0015] This measure makes it possible to check the consistency of a product cast in stick form by measuring the maximum force required to slice it.

[0016] The consistency of the composition is measured according to the following protocol: The stick is kept at 20°C + / - 2°C for 16 hours before measuring the consistency. The force is measured at 20°C using the "butter wire" method, which consists of cutting a stick of product, preferably cylindrical (11.6 mm diameter), transversely with a rigid tungsten wire 0.25 mm in diameter, moving the wire relative to the stick at a speed of 100 + / - 10 mm / min. Measurements are taken at least 10 mm from the sample holder. The hardness of the samples, expressed in grams, is measured, for example, using a static fragility tester (breakmeter - Industrial Electronics). The measurement is repeated three times and then averaged. The hardness is the average of the three values ​​read using the equipment mentioned above.

[0017] According to this measurement method, the composition according to the invention preferably has a consistency at 20°C and atmospheric pressure of between 55 and 150 g, more particularly 60 to 120 g. Viscosity measurement protocol

[0018] Viscosity measurement is generally carried out at 25°C, using a RHEOMAT RM 100 viscometer equipped with a No. 4 wheel, the measurement being carried out after 10 minutes of rotation of the wheel within the composition, at a shear rate of 200 revolutions / min (rpm). Generally, the composition according to the invention has a viscosity between 5 and 60 Pa.s, preferably from 10 to 50 Pa.s, even more particularly between 15 and 50 Pa.s. Protocol for measuring the color effect

[0019] To evaluate the particular color effect of the invention, the G parameter (graininess) is measured using a multi-angle spectrophotometer (the BYK Mac-I) from the BYK company.

[0020] The composition is considered to have the particular glossy effect, (“wet effect”), when the composition has a G value of at least 4, preferably between 4 and 12, preferably from 5 to 12. Below 4, the effect becomes more matte, this effect is accentuated with the decrease in the G value. On the other hand, too high a value of this coefficient leads to a makeup result that is too glossy, too shimmery, which would cause the loss of the natural appearance of human keratinous materials, in particular the lips.

[0021] Protocol: Step 1: For a liquid composition, homogenize the formula with a spatula. For a solid composition, it must be broken down prior to sample preparation, using a speed mixer at 2 x 3000 rpm for 1 minute. Step 2: Place an A4 sheet on the BYKO-DRIVE spreader and activate the vacuum. Prepare a LENETA Form IA Penopac Chart contrast card. Place the spread square on groove 2 (film thickness of 50.8 µm). Step 3: Take approximately 2g of the composition prepared in step 1 and place it on the edge, inside the spreading square, place the 980g weight on the spreading square and proceed with the application. Step 4: Allow the contrast card to air dry for 24 hours. Step 5: proceed with the measurement on the dark background with the spectrophotometer (3 successive measurements) and average the results of G. PIGMENT WITH ABSORBENT EFFECT

[0022] As previously stated, the composition comprises at least one absorbent pigment comprising a substrate in the form of calcium sodium borosilicate platelets and a coating applied to the substrate, comprising titanium, iron, and tin, the coating comprising a) optionally a layer 1 comprising or consisting of at least one tin oxide, tin hydroxide, and / or hydrated tin oxide; b) a layer 2 comprising at least one metal oxide and / or hydroxide and / or hydrated metal oxide; and c) a layer 3 comprising at least one metal oxide and / or hydroxide and / or hydrated metal oxide; at least one of the layers 2 and 3 comprising at least two different metal ions, chosen from titanium, iron, tin, and mixtures thereof; layers 2 and 3 being interrupted by at least one spacer layer.

[0023] By "interrupted" means, in the sense of the invention, that layers 2 and 3 are spaced or kept apart from each other by an intercalary layer.

[0024] In the following, the term "metal ion" will be used to indicate that the metal is in a non-zero degree of oxidation, to differentiate it from a metal in the elemental state (zero degree of oxidation).

[0025] Moreover, the term "oxide" is used to designate indifferently particular species such as monoxides, dioxides, trioxides, etc... The same remark is applied to the term hydroxide.

[0026] In a preferred embodiment, the optional layer 1 is directly adjacent to the substrate in the form of platelets, layer 2 directly follows layer 1 and layer 3 follows layer 2, layers 2 and 3 being interrupted by a spacer layer.

[0027] In another embodiment, layer 2 is directly adjacent to the substrate in the form of platelets and layer 3 follows layer 2, layers 2 and 3 being interrupted by a spacer layer. Substrate

[0028] The substrate is in the form of calcium sodium borosilicate glass platelets.

[0029] Preferably, the wafers may have the following composition, the contents being expressed by weight relative to the weight of the glass wafer: 65 to 75% by weight of silicon dioxide (SiO2) 2 to 9% by weight of aluminium oxide (Al2O3) 0.0 to 5% by weight of calcium oxide, preferably CaO 5 to 12% by weight of sodium oxide, preferably Na2O 8 to 15% by weight of boron oxide, preferably B2O3; 0.1 to 5% by weight of titanium oxide, preferably TiO2; 0.0 to 5% by weight of zirconium oxide, preferably ZrO2.

[0030] They can also be manufactured according to the process described in EP289240B1.

[0031] In another embodiment, the glass wafers can be colored in a controlled manner during their production by the addition of at least one inorganic dye. Suitable dyes are those that do not decompose at the specific melting temperature of the glass composition. Suitable dyes include, in particular, elemental noble metals such as Au, Pd, or Pt, complex cations or anions of the elements Cu, Cr, Mn, Fe, Ti, and / or Co, as well as mixtures of the dyes listed above.

[0032] The proportion of colorant is preferably in a range from 0.1 to 50% by weight, more particularly in a range from 1 to 35% by weight in total, preferably in a range from 5 to 25% by weight, relative to the total weight of the glass composition.

[0033] In another embodiment, the refractive index of the glass plates usable as a substrate is in a range from 1.45 to 1.80, preferably in a range from 1.50 to 1.70.

[0034] In another embodiment, the substrates, in the form of glass wafers, may be coated with a layer comprising or consisting of silicon dioxide, silicon hydroxide, or hydrated silicon dioxide. For example, the aforementioned coating, in the case of using glass wafers, can protect the glass surface from chemical alteration, such as swelling, leaching of the glass constituents, or dissolution in aggressive acidic covering solutions.

[0035] The average thickness of the substrate in the form of wafers is preferably within a range of 50 to 5000 nm, in particular from 60 to 3000 nm, and more advantageously from 70 to 2000 nm. For the purposes of this invention, average thickness means the arithmetic mean, unless otherwise specified. In one embodiment, the average thickness of the glass wafers is within a range of 750 to 1500 nm, preferably from 850 to 1400 nm, and more particularly from 900 to 1300 nm.

[0036] Thinner substrates in the form of wafers lead to a lower overall thickness of the absorbing pigments of the invention. Thus, in another embodiment, glass wafers with an average thickness in the range of 50 to 700 nm, preferably 101 to 600 nm, in particular 160 to 500 nm, and preferably in the range of 200 to 400 nm, can also be used.

[0037] In one embodiment, the relative standard deviation in the thickness distribution of the substrates in wafer form is 15 to 100%, preferably 17 to 70%, more preferably 19 to 61%, and even more preferably 21 to 41%. The relative standard deviation in [%] is the quotient of the calculated standard deviation and the average thickness.

[0038] The average thickness of the substrate in the form of wafers is determined using a hardened lacquer film in which the pigments with an absorbing effect are aligned essentially in a planar manner and parallel to the substrate, according to the details given in section Ilk of application US2017 / 0348201.

[0039] To this end, a cross-section of the hardened lacquer film is examined by scanning electron microscopy (SEM), the thickness of the substrate in the form of platelets being determined for at least 100 absorbing pigments and averaged statistically. According to the invention, the term "mean" always refers to the arithmetic mean, unless otherwise indicated.

[0040] Scanning electron micrographs were obtained from cross-sections of the absorbing pigments of the invention with the Supra 35 scanning electron microscope (from the Zeiss company). Coatings

[0041] Absorbing pigments optionally include a layer 1 comprising or consisting of tin oxide, tin hydroxide and / or hydrated tin oxide.

[0042] Layer 1 may optionally be present at least in part as a mixed layer with a layer directly adjacent to layer 1, for example layer 2.

[0043] Layers 2 and 3, after calcination, are preferably each a layer with a high refractive index, the refractive index n being preferably greater than 1.8, more preferably 1.9 and preferably 2.1.

[0044] According to the invention, the selection of two or more different metal ions in layers 2 and 3 is carried out in such a way that the metal oxide(s), metal hydroxide(s) and / or hydrated metal oxide(s) which form in layers 2 and / or 3 preferably each have an average refractive index of n greater than 1.8.

[0045] The metal oxide(s), metal hydroxides, and / or hydrated metal oxide(s) of layers 2 and 3 comprise at least two different metal ions, more particularly selected from the group of metals consisting of Ti, Fe, Sn, Mn, Zr, Ca, Sr, Ba, Ni, Sb, Ag, Zn, Cu, Ce, Cr, and Co, in particular from Ti, Fe, Sn, Mn, Zr, Ag, Zn, Cu, and Ce. According to the invention, the selection of the different metal ions is carried out such that the resulting effect pigments of the invention are absorbent.

[0046] By "absorbent effect pigments", for the purposes of the present invention, it is understood that their degree of coverage, Dq, defined as Dq = L*25biack / L*25white, is greater than or equal to 0.41, preferably to 0.45, more preferably to 0.50 and advantageously to 0.55. L*25biacket L*25white designate the brightness values ​​measured under a measurement angle of 25° on black and white backgrounds of black / white targets, preferably with the BYK-mac multi-angle colorimeter from Byk-Gardner.

[0047] The covering power is determined by applying a nitrocellulose lacquer (Erco 2615e colorless bronze mixing lacquer; from Maeder Plastiklack AG) which has been mixed onto a black / white contrast card (Byko-Chart 2853, from Byk-Gardner). with 6% by weight of said pigment, according to the details that follow in the Island section of US2017 / 0348201.

[0048] The proportion of non-coloring metal ions selected from the group of metals consisting of Ti, Sn, Zr, Ca, Sr, Ba and Zn is preferably 40% by weight, more preferably within a range of 0.1 to 35% by weight, advantageously from 1 to 24% by weight in total, and the proportion of coloring metal ions selected from the group of metals consisting of Fe, Ti, Sn, Mn, Ni, Sb, Ag, Cu, Ce, Cr and Co is preferably 4% by weight; the proportion of coloring metal ions being more particularly within a range of 5 to 80% by weight, advantageously from 20 to 72% by weight in total, determined respectively by XRF, calculated respectively as elemental metal and based respectively on the total weight of the absorbing pigment of the invention.

[0049] The weight ratio of non-coloring metal ions to coloring metal ions in the pigment with absorbing effect is here preferably less than 20, better less than 10, more preferably 1 and preferably 0.8.

[0050] The colouring metal ions of the Ti and Sn metal group relate in particular to Ti in the oxidation state +3 or +2 and Sn in the oxidation state +2.

[0051] The at least two different metal ions are preferably present either in homogeneous distribution in layers 2 and / or 3, or form a gradient there.

[0052] In exceptional cases, the at least two different metal ions may also be present in an inhomogeneous distribution in layers 2 and / or 3.

[0053] By "at least two different metal ions", it is meant that at least two metal ions of different elements are present, for example titanium and iron ions, or titanium and tin ions, or iron and tin ions, etc.

[0054] The different metal ions may be present in layer 2 and / or layer 3 of the pigment with absorbing effect in a mixture of metal oxides and / or metal hydroxides and / or metal oxide hydrates and / or in mixed oxides and / or mixed hydroxides and / or hydrated mixed oxides.

[0055] Layer 2 and / or layer 3 may comprise or be made up of this mixture of metal oxides and / or metal hydroxides and / or hydrated metal oxides and / or mixed oxides and / or mixed hydroxides and / or hydrated mixed oxides.

[0056] Preferably, in the case of use of metal ions Ti and Fe, the component comprising iron ions in the respective layer is present in layer 2 and / or in layer 3 in the calcined absorbing pigment, in the form of iron titanate, preferably in the form of pseudobrookite and / or pseudorutile.

[0057] In one embodiment, one of the two layers 2 and 3 comprises a single type of metal ion, preferably chosen from the group of metals consisting of Fe, Ti, Sn and Zr, more preferably consisting of Fe, Ti and Sn. Correspondingly, the other respective layer of the two layers 3 and 2 comprises at least two different metal ions, preferably chosen from the group of metals consisting of Ti, Sn, Zr and Fe, more preferably still consisting of Ti, Sn and Fe.

[0058] In a preferred embodiment, layer 2 and layer 3 comprise at least one metal oxide, metal hydroxide and / or hydrated metal oxide composed of or comprising at least two metal ions selected from the group of metals consisting of Ti, Sn, Zr and Fe, preferably still consisting of Ti, Sn and Fe.

[0059] In another embodiment, the layers 2 and 3 interrupted by the spacing layer are practically identical with regard to the particular composition.

[0060] If said absorbing pigments contain at least one coloring metal ion selected from the group of metals consisting of Fe, Ti, Sn, Mn, Cu, Cr, Co, Ag and Ce, the proportion of said ion, determined in each case by means of XRF and calculated in each case as an elemental metal, preferably totals at least 4% by weight, and is preferably also within a range of 6 to 85% by weight in total, more preferably from 8 to 79% by weight in total and preferably from 10 to 76% by weight in total, on the basis in each case of the total weight of said absorbing pigment.

[0061] In a preferred embodiment, at least one of the layers 2 and 3 comprises at least two different metal ions selected from the group of metals consisting of Ti, Fe, Sn, Mn, Zr, Ca, Sr, Ba, Ni, Sb, Ag, Zn, Cu, Ce, Cr and Co, where at least one of these two metal ions is selected from the group of metals consisting of Ti, Sn, Zr and Zn and where the proportion of colorant metal ions selected from the group of metals consisting of Fe, Ti, Sn, Mn, Cu, Cr, Co, Ag and Ce, determined respectively by XRF and calculated respectively as elemental metal, preferably greater than 4% by weight, relative to the total weight of said absorbing pigment.

[0062] In a particularly preferred embodiment, at least one of the layers 2 and 3 comprises metal oxides, metal hydroxides and / or hydrated metal oxides, the metal ions comprising or being the metals Ti and Fe, wherein the Ti / Fe weight ratio, determined respectively by XRF and calculated respectively as elemental metal, is less than 15, preferably less than 10, better still less than 5 and preferably less than 1, and wherein the proportion of Fe, determined by XRF and calculated as elemental metal, is preferably > 4% by weight, relative to the total weight of said absorbent pigment.

[0063] In another particularly preferred embodiment, at least one of the layers 2 and 3 comprises metal oxides, metal hydroxides and / or hydrated metal oxides, the metal ions comprising or being the metals Fe and Sn, the Fe / Sn weight ratio, determined respectively by XRF and calculated respectively as elemental metal, is preferably in a range of 1 to 80, preferably 2 to 60, more preferably 3 to 50 and particularly 4 to 40, and where the proportion of Sn, determined by means of XRF and calculated as elemental metal, is preferably chosen in a range of 1% to 25% by weight, preferably 2 to 19% by weight and more preferably 4% to 15% by weight, on the basis in each case of the total weight of said absorbing pigment.

[0064] The metal oxide, metal hydroxide, and / or hydrated metal oxide contents of the absorbent pigments of the invention are determined as respective metal oxides by means of X-ray fluorescence (XRF) analysis and can be calculated as respective elemental metals. For this purpose, the absorbent pigment is incorporated into a lithium tetraborate glass tablet, fixed in dosing cups for solid samples, and analyzed from this tablet. The measuring instrument used was the Thermo Scientific Advantix ARL system.

[0065] The average thickness of layer 1 is preferably less than 10 nm, more particularly less than 5 nm and preferably less than 3 nm, layer 1 completely or incompletely enveloping the substrate in the form of wafers or a coating possibly present.

[0066] The average layer thickness of each of the layers 2 and 3 of the absorbing pigments is preferably within a range of 30 to 350 nm, preferably 35 to 310 nm, even better 90 to 340 nm, more preferably 40 to 280 nm and preferably 50 to 210 nm.

[0067] In a preferred embodiment, the average thickness of layers 2 and 3 is practically the same.

[0068] By "practically the same average layer thickness", it is understood that the ratio of the average thickness of layer 2 and the average thickness of layer 3 is preferably in a range from 0.5 to 1.8, preferably from 0.5 to 1.8, in particular from 0.7 to 1.6, more particularly from 0.8 to 1.4 and preferably from 0.9 to 1.2.

[0069] In another embodiment, in the case of a different physical composition of layers 2 and 3, the respective optical layer thickness of these is practically the same, the optical layer thickness of layers 2 and 3 being able or not to follow the known rule lambda / 4.

[0070] The thickness of the optical layer is defined as the product of the refractive index and the average thickness of the respective layer.

[0071] The average thickness of the overall coating layer of the absorbing pigments is preferably < 800 nm.

[0072] The average thickness of the overall coating layer is preferably within a range of 45 to 650 nm, more preferably within 65 to 530 nm and preferably within 80 to 380 nm.

[0073] By "global coating" is meant the complete coating which starts from the surface of the substrate and extends perpendicularly to it in one direction.

[0074] In one embodiment, the relative standard deviation of the thickness distribution of layers 2 and 3 is from 2 to 74%, preferably from 3 to 63%, more preferably from 4 to 57% and more preferably from 5 to 49% and the relative standard deviation of the layer thickness distribution of the overall coating is from 0.3 to 31%, preferably from 1 to 27%, more preferably from 1.2 to 24% and more preferably from 1.9 to 22%.

[0075] The relative standard deviation in [%] is the quotient of the calculated standard deviation and the average thickness. Spacing layer

[0076] The spacer layer between layers 2 and 3 is preferably arranged essentially parallel to the surface of the substrate in the form of platelets.

[0077] By "essentially parallel" means that, on a scanning electron micrograph of a cross-section, a regression line drawn through a spacing layer, with respect to a regression line drawn on the surface of the substrate in platelet form, has a slope preferably close to 0.

[0078] The position of the spacer layer in the overall coating may vary.

[0079] If, for example, the average thicknesses of layers 2 and 3 are practically identical, the spacing layer, with respect to the overall coating, preferably composed of the optional layer 1 and layers 2 and 3, is located approximately in the middle of the overall coating since the optional layer 1 is preferably extremely thin, preferably only a few layers of atoms thick.

[0080] The interlayer (or spacer layer) is preferably disposed between the first sixth and the sixth sixth of the overall coating relative to the overall coating. The first sixth here refers to the proportion facing the substrate in the form of platelets, and the sixth sixth to the proportion of the overall coating away from the substrate in the form of platelets (see Figure 7 of US2017 / 0348201).

[0081] It should be noted that the spacing layer or layers include more particularly connections and cavities.

[0082] Thus, the intercalated layer formed between layers 2 and 3 preferably has connections, which can also be called spacers, which on the one hand connect the adjacent layers on either side of the intercalated layer and on the other hand keep them spaced apart.

[0083] As can be seen from scanning electron micrographs of cross-sections, these connections or spacers, for example in the form of bars or columns, can be arranged at an angle of approximately 90°, for example from 80° to 100°, relative to the surface of the substrate in the form of wafers. However, they can also take any other angle between 5° and 175°.

[0084] Preferably, the spacers, in particular the bars, preferably the longitudinal axes of the spacers, preferably the bars, are arranged at an angle between 15° and 150°, and more preferably at an angle between 35° and 135°, each case on the surface of the substrate in the form of plates.

[0085] When determining the angle, the plane of the substrate forms the first member. One of the outer sides of the bar in question constitutes the second member in each case.

[0086] The angle formed is determined from the apex of the angle of the two branches, 0° being assumed to be on the left and 180° on the right in the plane of the substrate in the top view of the scanning electron micrographs of cross-sections.

[0087] The connections or spacers can take various geometric forms and are preferably distributed homogeneously over the entire spacing layer. For example, the connections or spacers can take the form of lattices, grids, ladders, sponges, or honeycombs.

[0088] It may also be possible to identify certain structural elements similar to those of a photonic or inverse photonic crystal, as known for example by EP2371908, EP1546063 or EPI 121334.

[0089] The connections or spacers comprise at least one metal oxide, one metal hydroxide and / or one hydrated metal oxide.

[0090] In a preferred embodiment, the connections or spacers comprise a physical composition identical to the layers on either side of the spacer layer.

[0091] Alternatively, it is also possible that a gradient between various metal oxides, metal hydroxides and / or metal oxide hydrates may be formed inside the connections or spacers.

[0092] In a preferred embodiment, the connections or spacers comprise a metal oxide, a metal hydroxide and / or a hydrated metal oxide, the metal ions comprising or being at least two metal ions selected from the group of metals consisting of Ti, Fe, Sn, Mn, Zr, Ca, Sr, Ba, Ni, Ag, Zn, Cu, Ce, Cr and Co, more preferably still from the group consisting of Ti, Fe, Sn, Mn, Zr, Ag, Zn, Cu and Ce, more preferably from the group consisting of Ti, Fe, Sn, Zr, Ag and Ce, and more preferably still from the group consisting of Ti, Fe and Sn.

[0093] The spacing layer of the effect pigments preferably has an average height ha within a range of 5 to 120 nm, preferably from 9 to 95 nm, of preferred manner from 16 to 76 nm, preferably from 21 to 69 nm, more advantageously from 22 to 62 nm, preferably from 26 to 56 nm (see Figure 6 of US2017 / 0348201).

[0094] To determine the average height ha of the spacing layer, the average thickness of layers 2 and 3 and the average thickness of the overall coating layer, scanning electron micrographs of cross-sections are used to establish the upper and lower surfaces of the substrate as baselines.

[0095] What is meant by upper and lower surfaces of the substrate in scanning electron micrographs of cross-sections is the longer side of the substrate in the form of platelets in each case.

[0096] The baseline is drawn on the scanning electron micrograph of the cross-section along the surface of the substrate in the form of platelets.

[0097] Scanning electron micrographs of cross-sections were analyzed using AxioVision 4.6.3 image processing software (from Zeiss).

[0098] A sufficient number of parallel lines are drawn at 50 nm intervals at an angle of 90° from these two baselines in order to place a grid on the effect pigment shown on the scanning electron micrograph of the cross-section (see Figure 4 of US2017 / 0348201)

[0099] The magnification of the scanning electron micrograph of the cross-section is preferably at least 50,000 times, based on the Polaroid 545 (4" x 5").

[0100] Starting from the respective baseline of the substrate in the form of plates, in the direction of the respective outermost layer 3 or outermost layer, the points of intersection between the parallel lines arranged perpendicular to the respective baseline with the respective interfaces of the optional layer 1 with layer 2, layer 2 with the spacing layer, the spacing layer with layer 3 and layer 3 with the environment or with any other applied layer are analyzed manually.

[0101] It may be here that one of the lines drawn at intervals of 50 nm is located directly above a connection point or a spacer.

[0102] In this case, only the respective intersection point at the interface of layer 3 with the environment or with any other applied layer is recorded.

[0103] These measurements give the layer thicknesses of layers 2 and 3, the layer thickness of the overall coating, the layer thickness of other layers possibly present and the height ha of the spacing layer by difference formation.

[0104] The layer thickness of layer 2 is calculated from the difference between the respective measured intersection points at the respective interfaces of layer 2 with the spacing layer and either of the optional layer 1 with layer 2, or of the baseline with layer 2 if the substrate in the form of wafers has not been covered with other layers beforehand.

[0105] The layer thickness of layer 3 is calculated from the difference between the respective measured intersection points of layer 3 with the environment or any other applied layer and of the spacing layer with layer 3.

[0106] The overall coating layer thickness is calculated from the difference between the respective intersection points of layer 3 with the environment or any other applied layer with the environment and the respective baseline.

[0107] The height ha of the spacing layer is calculated from the difference between the respective measured intersection points of the spacing layer with layer 3 and of layer 2 with the spacing layer.

[0108] The layer thicknesses of any other layers applied can be determined in a similar manner and should be taken into account accordingly when forming differences.

[0109] The individual values ​​of the layer thicknesses and the height ha thus determined are used to form the respective arithmetic means in order to determine the values ​​indicated above for the average layer thicknesses and the average height ha.

[0110] To be statistically significant, the measurements described above are carried out on at least 100 of the parallel lines arranged perpendicular to the baselines.

[0111] The height hma refers to the middle of the spacing layer.

[0112] It is calculated as the total sum of the thickness of the optional layer 1 and layer 2 and half the height ha of the spacing layer.

[0113] The relative height hRma of the midpoint of the spacing layer is formed from the ratio between hma and the thickness of the overall coating layer.

[0114] The standard deviation of the relative height ohRma is preferably within a range of 0.2 to 18%, more preferably still within a range of 0.3 to 15%, more preferably within a range of 0.4 to 11% and more preferably still within a range of 0.5 to 8%.

[0115] The standard deviation of the relative height ohRma is a value of the measure in which the spacing layer is in a defined position parallel to the surface of the substrate in the form of plates over the whole of the coating.

[0116] If the absorbing pigments have at least one other spacer layer, the height hma of this layer and the relative height of the middle of the other spacer layer hRma of this layer are determined by the method described above using scanning electron micrographs of cross-sections.

[0117] The values ​​indicated above for the standard deviation of the relative height ohRma apply accordingly to the other spacing layers.

[0118] Those skilled in the art know that pearlescent pigments coated, for example, with titanium dioxide have pores in the coating that are statistically distributed throughout the coating (see Figure 5 of US2017 / 0348201). These pearlescent pigments do not have a spacer layer.

[0119] On the other hand, the spacer layer and the cavities present within the spacer layer in the absorbent pigments of the invention are not statistically distributed over the whole of the coating, but are arranged parallel to the surface of the substrate in the form of platelets over the whole of the coating.

[0120] The distances between the midpoints of the statistically distributed pores and the substrate surface were also determined by means of scanning electron micrographs of cross-sections by the method described above.

[0121] To this end, a sufficient number of parallel lines were drawn at 50 nm intervals at an angle of 90° to the upper and lower baselines corresponding to the two surfaces of the substrate in the form of platelets so that a grid was placed on the pearlescent pigment without a spacer layer shown on the scanning electron micrograph of a cross-section.

[0122] If one of the parallel lines appeared above one or more pores, the height(s) of the line, the midpoint(s) of the pores and the distance of the midpoint(s) of the pores from the surface of the substrate were determined.

[0123] The statistical distribution of the pore midpoints can also be used to determine a standard deviation.

[0124] The standard deviation of the distances between the median points of the statistically distributed pores and the surface of the substrate is greater than 20% in the pearlescent pigments of the prior art, i.e. in the case of pearlescent pigments without a spacer layer.

[0125] The standard deviation of the distances of the median points of the statistically distributed pores with respect to the surface of the substrate is thus clearly different in terms of the value of the standard deviation of the relative height of the midpoint of the spacing layer of the absorbing pigments.

[0126] It is thus possible to compare the standard deviation of the distances from the pore media to the surface of the substrate of pearlescent pigments without an intercalary layer with the standard deviation of the relative height of the midpoint of the spacer layer of the pigments with an absorbing effect of the invention.

[0127] Furthermore, using the lines described above drawn at 50 nm intervals on a scanning electron micrograph, the number of connections or spacers per micrometer and the network density, defined as the number of connections or spacers per number of lines in %, is determined.

[0128] If the absorbent pigments have more than one spacer layer in the overall coating, the method just described for measuring the individual layers and the spacer layers is applied accordingly.

[0129] In one embodiment, the relative standard deviation in the height distribution of the spacing layer is 4 to 75%, preferably 7 to 69%, more preferably 9 to 63%, and even more preferably 13 to 60%. The relative standard deviation in [%] of the height distribution is the quotient of the calculated standard deviation and the mean height.

[0130] In a preferred embodiment, the absorbing pigments within the spacer layer have a number of connections or spacers per micrometer in a range of 0 to 11, preferably still in a range of 0 to 9, more preferably in a range of 1 to 7 and preferably in a range of 1 to 3.

[0131] In a preferred embodiment, the absorbing pigments have, within the spacer layer, a network density, defined as the number of connections or spacers per number of lines as a percentage, of less than 85%, preferably from 1% to 75%, more preferably from 1% to 63% and preferably from 1% to 49%.

[0132] Beyond a network density of 85%, there is no longer any reference to a spacing layer since the high proportion of connections or spacers then leads to a very substantially continuous coating.

[0133] In another preferred embodiment, the absorbing pigments comprise at least one spacer layer arranged essentially parallel to the surface of the substrate in the form of platelets, the spacer layer having in each case an average height ha within a range of 19 to 83 nm, more preferably within a range of 27 to 66 nm and even more preferably within a range of 33 to 57 nm.

[0134] In a particularly preferred embodiment, the absorbing pigments have at least one spacer layer with an average height ha in a range of 16 to 79 nm, preferably 21 to 66 nm and preferably 23 to 57 nm, the number of connections or spacers per micrometer inside the spacer layer being chosen in a range of 0 to 8, preferably 0 to 6, more preferably 1 to 5 and preferably 1 to 4.

[0135] The spacer layer includes cavities as well as the connections or spacers described above.

[0136] These cavities are spatially delimited by layers 2 and 3 and the connections or spacers.

[0137] Energy-dispersive X-ray microanalysis (EDX analysis) of these cavities does not allow any conclusion as to whether the material is solid or liquid. In this case, with the currently available analytical methods, it is assumed that the cavities inside the spacer layer contain a gas, probably air.

[0138] The connections or spacers include, on the other hand, at least one metal oxide, one metal hydroxide and / or one hydrated metal oxide, as detailed above.

[0139] The cavities inside the spacer layer of the absorbing pigments can take an average height hH in a range from 2 to 119 nm, preferably in a range from 6 to 105 nm, more preferably in a range from 11 to 85 nm and preferably in a range from 18 to 53 nm.

[0140] By height hH we mean the greatest difference between the upper and lower limits of the cavity.

[0141] It is determined by the method described above for the height ha, by drawing parallel lines at intervals of 50 nm at an angle of 90° to the surface of the substrate in the form of platelets in scanning electron micrographs of cross-sections.

[0142] The difference between the two points of intersection of these lines with the upper and lower limits of the cavity is the height hH. Here too, to be statistically significant, the measurements described above are taken on at least 100 lines. Therefore, the average height ha is a maximum value for the average height hH.

[0143] Consequently, it is also possible that a plurality of cavities may be present one on top of the other inside the spacing layer.

[0144] The average height of the spacer layer ha and the average height of the cavities hH are determined, using a hardened lacquer film in which the pigments with an absorbing effect are aligned essentially in a planar manner and parallel to the substrate, according to the details given in section Ilk (see US2017 / 0348201).

[0145] To this end, a cross-section of the hardened lacquer film is examined by scanning electron microscopy (SEM), as described above for ha.

[0146] As an alternative to these cross-sections, absorbing pigments can be cut using the FIB (Focused Ion Beam) method. For this purpose, a thin beam of highly accelerated ions (e.g., gallium, xenon, neon, or helium) is focused to a point using ion optics and guided line by line across the surface of the pigment to be treated. Upon impact on the surface of the pigment, the ions release most of their energy and destroy the coating at that point, resulting in material being removed line by line.

[0147] It is also possible, using the scanning electron micrographs which were subsequently recorded by the method described above, to determine the average height ha, the average thickness of layers 2 and 3 and the average thickness of the entire coating.

[0148] The average thickness of the substrate in the form of platelets can also be determined using scanning electron micrographs of the effect pigments cut by the FIB method.

[0149] In another embodiment, the absorbing pigments comprise, within the intercalated layer, distributed over the whole of the effect pigment and measured by scanning electron micrographs of cross-sections, a surface proportion of cavities in a range of 51 to 99%, preferably in a range of 63 to 96%, more preferably in a range of 76 to 95% and preferably in a range of 84 to 94%, and a surface proportion of connections or spacers in a range of 1 to 49%, preferably in a range of 4 to 37%, more preferably in a range of 5 to 24% and preferably in a range of 6 to 16%.

[0150] It is also preferable that the total volume occupied by the connections and spacers in the spacing layer be less than the total volume occupied by the cavities.

[0151] Preferably, the total volume occupied by the connections or spacers in the spacing layer is less than 50% by volume, preferably still less than 30% by volume, more preferably less than 20% by volume and preferably less than 10% by volume of the total volume occupied by the cavities.

[0152] According to the invention, the cavities which are not randomly distributed throughout the coating but are present essentially parallel to the surface of the substrate in the form of platelets inside the spacer layer do not have an adverse effect on the optical properties of the absorbing pigments of the invention.

[0153] The gloss of the effect pigments is determined using white / black swatches with a Micro-Tri-Gloss glossmeter from Byk-Gardner, according to the details given in section IId "Gloss Measurements" (see US2017 / 0348201).

[0154] The saturation of the absorbing pigments of the invention is also determined using white / black patches with the BYK-mac multi-angle colorimeter (from the company Byk-Gardner), according to the details given below in section IIb (see US2017 / 0348201).

[0155] In one embodiment, the absorbing pigments comprise, in addition to the layers 1, 2 and 3 described above, other layers with high and / or low refractive index, which can be arranged, viewed from the substrate, in the form of plates, either below the optional layer 1, or in layer 2 and / or above layer 3.

[0156] These additional layers may comprise metal oxides, metal hydroxides, hydrated metal oxides, metal ions comprising or being at least one metal ion selected from the group of metals consisting of Ti, Fe, Sn, Mn, Zr, Ca, Sr, Ba, Ni, Ag, Zn, Cu, Ce, Cr and Co, preferably from Ti, Fe, Sn, Zr, Ag, Zn, Cu, Ce, Cr and more preferably from Ti, Fe and Sn. In addition, these other layers may comprise semi-transparent metals selected from the group consisting of Ag, Al, Cr, Ni, Au, Pt, Pd, Cu, Zn and Ti, preferably Ag, Au and Cu, alloys of each and / or mixtures thereof.

[0157] More particularly, the other layers are chosen such that the proportion of colouring metal ions chosen from the group of metals consisting of Fe, Ti, Sn, Mn, Cu, Cr, Co, Ag and Ce, determined respectively by means of XRF and calculated in each case as elemental metal, preferably totals greater than 4% by weight, and is preferably still within a range of 5 to 82% by weight in total, more preferably 7 to 72% by weight in total and preferably 10 to 68% by weight in total, on the basis in each case of the total weight of the pigment with absorbing effect.

[0158] In addition, the proportion of at least one semi-transparent metal, determined by means of XRF, preferably amounts to at least 1% by weight, and is more preferably within a range of 2 to 20% by weight in total and advantageously, of 3 to 12% by weight in total, respectively with respect to the total weight of the absorbing pigment.

[0159] If the pigments with absorbing effect comprise at least one colouring metal ion and at least one semi-transparent metal, whether they are in the substrate in the form of platelets or in the coating, their proportion preferably amounts to at least 5% by weight, based on the total weight of the pigment with absorbing effect.

[0160] In one embodiment, each layer of the absorbing pigments may be provided with a dopant, the dopant comprising metal oxides, metal hydroxides and / or metal oxide hydrates, and the metal ions being selected from Ca, Mg, Al, Ce, Zr or Sn, preferably Al, Zr or Sn. The proportion of dopant is preferably at most 1% by weight, more preferably at most 0.5% by weight and preferably at most 0.2% by weight, relative to the total weight of the absorbing pigments.

[0161] In another embodiment, the overall coating of the absorbent pigments may, in addition to the spacer layer, comprise at least one other layer spacing also arranged essentially parallel to the surface of the substrate in the form of plates between layers 2 and 3.

[0162] Preferably, the absorbing pigments of the invention do not have more than four spacer layers within the overall coating, because their optical quality then decreases.

[0163] It should be noted that even when the effect pigment comprises more than one interlayer, in relation to the overall coating, there is no interlayer in either the first sixth or the sixth sixth of the overall coating.

[0164] The absorbing pigments can have any median particle size D50. The D50 values ​​of the absorbing pigments of the invention are preferably in a range from 3 pm to 350 pm.

[0165] Preferably, the D50 values ​​of the absorbing pigments are in a range from 4 to 211 pm, preferably from 6 to 147 pm, more particularly from 7 pm to 99 pm and preferably from 7 to 99 pm, or even from 8 to 56 pm.

[0166] Exceptionally preferred, the absorbing pigments have a D50 value in the range of 3 to 15 pm, more particularly 10 to 35 pm, especially 25 to 45 pm, advantageously 30 to 65 pm, preferably 40 to 140 pm, or even 135 to 250 pm.

[0167] The D10 values ​​of the absorbing pigments preferably extend in a range from 1 pm to 120 pm. Even more preferably, the D10 values ​​of the absorbing pigments are in a range from 1 to 5 pm or in a range from 5 to 25 pm or in a range from 10 to 30 pm or in a range from 20 to 45 pm or in a range from 25 to 65 pm or in a range from 75 to 110 pm.

[0168] The D90 values ​​of the absorbing pigments preferably extend in a range from 6 pm to 500 pm. Even more preferably, the D90 values ​​of the absorbing pigments of the invention are in a range from 8 to 250 pm or in a range from 10 to 150 pm or in a range from 40 to 70 pm or in a range from 68 to 110 pm or in a range from 120 pm to 180 pm or in a range from 400 to 490 pm.

[0169] The D10, D50 and D90 of the cumulative frequency distribution of the volume mean size distribution function, as obtained by laser diffraction methods, indicate that, respectively, 10%, 50% and 90% of the analyzed effect pigments have a volume mean diameter less than, greater than or equal to, the value specified in each case.

[0170] The size distribution curve of the absorbing pigments is determined using the Malvern Mastersizer 2000 instrument according to the manufacturer's instructions.

[0171] The scattered light signals are evaluated by the Fraunhofer theory, which also includes the diffraction and absorption characteristics of the particles.

[0172] In a preferred embodiment, the absorbing pigments of the invention have an AD range, defined as AD = D90-D10 / D50, in a range of 0.7 to 2.0, preferably in a range of 0.7 to 1.5, preferably still in a range of 0.8 to 1.3, more preferably in a range of 0.8 to 1.2 and most preferably in a range of 0.85 to 1.1.

[0173] Reference may be made to US application 2017 / 0348201 for further details on pigments with absorbent effect and their preparation processes.

[0174] More particularly the pigment with absorbent effect used in the composition according to the invention has the following INCI name: Calcium Borosilicate (and) Titanium Dioxide (and) Iron Oxide (and) Tin Oxide.

[0175] This type of pigment is notably marketed under the name Mirage Glamour Space Silver by the company Eckart.

[0176] Advantageously, the effect pigment is present at a content ranging from 0.1 to 8% by weight, preferably from 0.15 to 6% by weight, relative to the total weight of the composition. FIRST MOTHER-OF-PEARL

[0177] As stated previously, the composition comprises at least a first nacre, which is more particularly a glossy black nacre, consisting of a laminated aluminium oxide substrate preferably transparent in the form of platelets having an aspect ratio of at least 85, and a coating comprising a layered structure consisting of a first layer composed of hematite and / or goethite, a second layer composed of magnetite, and optionally, another colorless dielectric layer on the magnetite layer, in this sequence, on the substrate.

[0178] It is recalled that the aspect ratio is the ratio between the average size of the particles and their thickness.

[0179] More particularly, the aluminum oxide substrate in the form of platelets of the first nacre refers more particularly to a particulate substrate having an upper surface and a lower surface which both constitute the principal surfaces of the particulate substrate and are parallel to each other.

[0180] These substrate particles are preferably transparent and of homogeneous composition.

[0181] “Parallel” does not only mean strictly parallel in the geometric sense, but also substantially parallel in the sense that the main surfaces are smooth and flat and the angle of deviation from the geometrically parallel surfaces is not greater than 15°.

[0182] The extension of the principal surfaces in length and width constitutes the largest dimension (particle size) of the laminated particles in the form of platelets (or platelet-like laminated particles). The difference in length between the The main surfaces constitute the thickness of the laminated substrates. In general, the thickness of platelet substrates is much smaller than the particle size of the first nacre. The aspect ratio of the substrate particles, which is the ratio of particle size to thickness, is at least 85 and preferably > 100, but can also reach 200. This applies at least to the ratio of the average particle size to the average thickness of the substrate particles as such, but preferably to the actual ratio of particle size to the thickness of each individual substrate particle.

[0183] The particle size (particle diameter) of first nacre can be measured by various methods, for example, by laser diffraction using a commercially available instrument, such as the Malvern Mastersizer 2000, APA200, a product of Malvern Instruments Ltd. The advantage of this method is that, in addition to the actual particle size, the particle size distribution within a pigment fraction or pigment mixture can also be measured by the standard operating procedure (SOP). To determine the particle size as well as the thickness of a single first nacre particle, scanning electron microscopy (SEM) images can be advantageously used, where the thickness and particle size of each individual particle can be measured directly.

[0184] Laminated substrates are said to be "transparent" if they transmit a significant amount of visible light, i.e. at least 90% of the incoming visible radiation.

[0185] The laminated substrates are also homogeneous in their composition, that is to say, they are made of the same material, either a single compound, a mixture of compounds, or a mixed oxide, at every location within the substrate. In particular, there are no gradients or distinct zones of different materials within the same substrate particle.

[0186] The substrate particles used are synthetically produced substrate materials composed of aluminum oxide, such as Al₂O₃ or Al₂O₃ containing up to 5% by weight of TiO₂, relative to the weight of the substrate, both hereafter referred to as aluminum oxide wafers. They are preferably in the form of single crystals. These nacres can be produced by precisely controlling the particle thickness and the smoothness of the external surfaces, and, furthermore, by also controlling the variation in particle thickness and the particle size distribution at the end.

[0187] Reference may be made to patent EP763573.

[0188] The aluminum oxide wafers used (or substrate) preferably have an average thickness between 50 and 250 nm, preferably between 100 and 200 nm, and most preferably between 30 and 170 nm. The thickness variation of the particles the substrate content is preferably not greater than 10% and can be controlled by the production process of the corresponding substrate particles.

[0189] The average diameter (D50) of the substrate particles, which corresponds to the largest dimension of the substrate, i.e., the particle size, is less than 20 pm, generally between 5 and 19 pm, particularly less than 16 pm, especially between 5 and 15 pm. D50 values ​​of 10 to 15 pm are preferred. A narrow particle size distribution is particularly advantageous. The particle size distribution can be controlled by the process parameters as well as by any grinding and / or classification process that may be performed.

[0190] As stated above, the first nacre comprises a flake aluminium oxide substrate having an aspect ratio of at least 85 and a coating.

[0191] The coating comprises a layered structure consisting of a first layer composed of hematite and / or goethite and a second layer composed of magnetite, in this sequence, on the substrate. This second layer may be a coating on the two main surfaces of the substrate, but preferably encapsulates the transparent substrate such that all the external surfaces of the transparent sheet substrate are coated with the hematite / goethite-magnetite layered structure.

[0192] It goes without saying that the layered hematite / goethite-magnetite structure need not necessarily have the same thickness at every point on the surface of the substrate and that even some smaller surface areas of the substrate may not be perfectly coated with the layered structure or, at least, with the hematite / goethite layer mentioned above.

[0193] The layer composed of hematite and / or goethite is hereinafter referred to as the "hematite layer." Its actual composition depends on the precipitation conditions used for its preparation. For the conditions given in the process described in application WO2012 / 076110, the composition of the hematite layer has been found to be preferably either pure hematite (alpha Fe2O3, ferric oxide) or hematite containing goethite (alpha FeO(OH), hydrated ferric oxide). Usually, the goethite content is lower than the hematite content.

[0194] The layer composed of magnetite is hereinafter referred to as "magnetite layer" and, in the case where it is produced by the process described in application WO2012 / 076110, is composed either of pure magnetite (Fe3O4) or of magnetite containing very small amounts of maghemite (gamma Fe2O3).

[0195] According to a preferred embodiment, the thickness of the magnetite layer within the layered structure is greater than the thickness of the hematite layer. Typically, the thickness of the magnetite layer within the structure in layers is advantageously at least 10 times greater than the thickness of the hematite layer.

[0196] The hematite layer is applied to the substrate particles (possibly pre-coated) with a very thin layer thickness, using a molecular monolayer and having an upper limit of approximately 5 nm. Typically, the hematite layer thickness is between 0.1 and 3.5 nm, preferably between 0.1 and 2.5 nm. It should be noted that the hematite layer can act as a binder for the magnetite layer, which is to be applied over the hematite layer below.

[0197] Moreover, particularly with regard to aluminium oxide flakes used as substrate particles, or with regard to any pre-coatings they carry, the outer surfaces usually obtained from these particles are often not particularly useful for being directly coated with iron oxides at an acidic to neutral pH value rather lower than that used for the direct coating of Fe3O4 according to the present invention.

[0198] The hematite layer, which can also serve as a means of activating the surface of the substrate particles, is most particularly deposited directly onto the substrate or onto the pre-coated substrate, since it could be directly precipitated onto the aluminum oxide wafers or dielectric layers that act as pre-coatings and itself provides an activated surface, which is advantageous for the precipitation of the subsequent magnetite layer. Furthermore, the very smooth and flat surface of the substrate particles can be maintained by precipitating a dense and uniform, but ultra-thin, hematite layer.

[0199] Moreover, since the underlying substrate contains or is composed of A12O3 crystals, the next hematite layer is able to form crystals in the same crystal structure as that present in the underlying substrate, namely in the crystal structure of corundum, which is advantageous for the formation of a dense hematite layer.

[0200] In such a case, the growth of the hematite layer on the substrate which contains or is essentially composed of Al2O3 crystals is similar to an epitaxial crystal growth process of a crystalline layer on a solid substrate.

[0201] Furthermore, the presence of the hematite layer is also advantageously useful for forming a dense, flat, and substantially crystalline layer of Fe3O4 directly on it by a precipitation procedure not using an oxidizing agent. The thickness of the substrate particle layer and the thickness of the hematite layer must be adjusted because the hematite layer is so thin that it does not, in itself, contribute to the interference of the pigment but only in combination with the other layers and the substrate, respectively.

[0202] The magnetite layer is present in a thickness ranging from 50 nm to 250 nm, in particular from 80 nm to 180 nm. It is adjusted so as to obtain a weak bluish interference color of the resulting nacre (the deposition can be controlled by known means in the process of precipitation of the magnetite layer).

[0203] The magnetite layer, in particular, exhibits a dense, crystalline structure. The regularity of the substrate particles can be maintained, so that the magnetite layer itself is also smooth, dense, and flat. It has a high refractive index greater than 2.0 (approximately 2.4). In addition to its faint bluish interference color, the magnetite layer also imparts, through absorption, a black-body color and intense luster to the resulting pigments.

[0204] In addition, it is preferable that the magnetite layer be doped with at least one aluminum compound, which is preferably an aluminum oxide and / or an aluminum oxide hydrate.

[0205] Doping is achieved by adding a suitable aluminum compound while the magnetite layer is precipitated onto the pre-coated hematite substrate particles. Useful aluminum compounds include, for example, aluminum sulfates, aluminum chlorides, or aluminum nitrates. Al doping of the magnetite layer contributes to the optical behavior of the magnetite layer and facilitates the precipitation of the next layer onto the magnetite layer, if present.

[0206] Aluminum oxide and / or aluminum oxide hydrate, as mentioned above, are present in the magnetite coating with a content preferably between 0.1 and less than 5% by weight, relative to the weight of the magnetite coating. They do not form mixed oxides with the iron component because their content is far too low. Instead, they are present as aluminum oxide and / or hydrated oxide itself, for example as Al₂O₃ or Al₂O₅OH, in the magnetite coating. Besides the fact that the subsequent dielectric layer can be deposited on the magnetite layer much more easily when the magnetite layer is doped with an Al component, the brilliance of the resulting nacres can be further enhanced with this.

[0207] The embodiment in which the magnetite layer is doped with an aluminum compound as described above is preferred. The most preferred embodiment is that in which the substrate material is an aluminum oxide wafer as defined above, having no pre-coating but a single-layer structure directly on and encapsulating the substrate, the layered structure being composed of a first hematite layer and a second a layer of magnetite doped with an Al component as defined above, followed by at least one colorless dielectric layer on top of the magnetite layer.

[0208] Such a pre-coating can, among other things, be applied to improve the surface characteristics of substrate particles, in order to adapt the thickness of the substrate particles to a desired degree or to facilitate the coating process to coat the layered structure mentioned above.

[0209] The adaptation of the interference color of the brilliant black nacres is not, however, the main objective of such a pre-coating, since the magnetite layer within the stratified structure will give the pigment obtained a black body color and a bluish interference color itself and will also absorb most of the incoming light, i.e. at least 70% of it.

[0210] Nevertheless, the aluminum oxide wafers as defined above may be pre-coated with at least one dielectric coating before coating the substrate particles with the layered structure consisting of the hematite layer and the magnetite layer. Preferably, the thickness of the pre-coating, if any, will be moderate, preferably in a range of 0.1 to 50 nm, depending on the materials used for the pre-coating.

[0211] As pre-coating materials, dielectric materials are used, in particular dielectric materials that are commonly used in the production of interference pigments. These materials may have a high (> 1.8) or low (< 1.8) refractive index and may include oxides and / or hydrated oxides of titanium, iron, chromium, zinc, zirconium, tin or silicon, alone or in mixtures thereof.

[0212] In the case where such a dielectric pre-coating is applied to the substrate, said dielectric pre-coating is located between the substrate and the first layer (hematite layer) of the layered structure described above.

[0213] Preferably, no pre-coating is present prior to the application of the layered structure consisting of the hematite layer and the magnetite layer. Therefore, the layered structure consisting of the hematite layer and the magnetite layer as defined above is located directly on the substrate, and in particular, completely encapsulates the substrate.

[0214] Unlike pre-coatings, at least one dielectric layer above the hematite / magnetite layered structure is preferably present in the black mother-of-pearls used in the compositions according to the invention. In this case, the dielectric layer is located directly above the magnetite layer.

[0215] Dielectric metal oxides or metal oxide hydrates are generally used as materials for these dielectric layers. Although they can also be colored under certain circumstances, the dielectric layers advantageously are colorless dielectric layers composed of colorless metal oxides or hydrates of colorless metal oxides or mixtures thereof, for example tin oxide, cerium oxide, silicon dioxide, zirconium dioxide and aluminium dioxide, or their hydrates.

[0216] The thickness of these dielectric layers which are used in addition to the hematite / magnetite layered structure depends on the use for which they are intended.

[0217] In the case where the interference color of the brilliant black nacres needs to be adapted, the thickness of the dielectric layer above the magnetite is advantageously adjusted between 20 and 100 nm.

[0218] According to a preferred embodiment, there is at least one colorless dielectric layer above the magnetite layer. Preferably, this dielectric layer is composed of a colorless dielectric material with a low refractive index. A single dielectric layer of hydrated silicon dioxide located directly above the magnetite layer is preferred.

[0219] Hydrated silicon oxide is a dielectric material with a dense amorphous structure and is therefore very useful for protecting the underlying magnetite layer and, if necessary and by adjusting the thickness according to the knowledge of those skilled in the art, for attenuating the faint bluish interference color of the magnetite layer. For this purpose, the hydrated silicon oxide layer must have a certain thickness, which is considerably thicker than the thickness of typical subsequent coatings, which may, among other things, be composed of silicon dioxide or its hydrate.

[0220] Nevertheless, the hydrated silicon oxide layer can also be used as a pure protective layer (subsequent coating).

[0221] Thus, the thickness of the silicon oxide hydrate layer located above the magnetite layer in black nacres is between 5 and 100 nm, in particular between 5 and 50 nm and preferably between 5 and 30 nm.

[0222] In the case where the hydrated silicon oxide layer located above the magnetite layer of the nacre acts as an interference layer rather than as a subsequent coating, the thickness of the layer of the latter is advantageously adjusted so as to decrease rather than intensify the interference colour of the underlying nacres.

[0223] The nacres obtained exhibit a deep black body colour, a weak or very weak bluish interference colour and an excellent luster.

[0224] Furthermore, glossy black mother-of-pearls could be adapted to their application requirements by including a so-called "post-coating," distinct from or in addition to the hydrated silicon oxide layer. In this case, dielectric layers may also be used. This type of post-coating confers a better dispersibility, better resistance to light, etc., to mother-of-pearl and are well known in art.

[0225] So-called "post-coatings" based on inorganic dielectric compounds generally have a thickness of less than 20 nm, and in particular between 1 and 15 nm, preferably between 2 and 10 nm. Dielectric layers of this type will not cause any interference to the system. Very thin layers of silicon dioxide (here in systems layered with other subsequent coatings), aluminum oxide, cerium oxide, and / or tin oxide and similar materials are used, alone or in mixtures. For this purpose, several very thin dielectric layers of different materials, as mentioned above, are often superimposed.

[0226] Of course, the colorless dielectric layer and the layers intended to improve application properties can be used together in an embodiment. In particular, said black pearlescent pigments, consisting of an aluminum oxide platelet having a layered hematite / goethite-magnetite structure and a hydrated silicon oxide layer on top, can further be provided with subsequent inorganic coating(s) to give them better application properties in specific compositions.

[0227] In addition to or as an alternative to inorganic dielectric layers for subsequent coatings as described above, thin coatings of organic materials, for example of various organic silanes, organic titanates, organic zirconates, can also be applied to the surface of nacres in order to improve their application capabilities in specific compositions.

[0228] Such coatings are known in the art of effect pigments and their application therefore falls within the skills of a person skilled in the art.

[0229] Examples of what is called "post-processing" of effect pigments, of organic or inorganic nature, which can be used for nacres as described above, can be found in the following documents: EP632109, US5759255, DE4317019, DE3929423, DE3235017, EP492223, EP342533, EP268918, EP141174, EP764191, WO98 / 13426 or EP465805.

[0230] The first mother-of-pearl used in the composition according to the invention is known and, in particular, described in application WO2012076110, to which reference may be made. The processes for preparing such mother-of-pearl are also described in that international application.

[0231] Suitable for implementing the invention is Ronastar Diamond Black IQ mother-of-pearl, marketed by Merck.

[0232] Advantageously, the first nacre is present at a content ranging from 0.1 to 10% by weight, preferably from 0.15 to 8% by weight, relative to the total weight of the composition. SECOND MOTHER-OF-PEARL BASED ON ALUMINUM OXIDE

[0233] As previously stated, the composition according to the invention optionally comprises at least a second nacre made of aluminium oxide, titanium oxide and optionally tin oxide.

[0234] More particularly, the mother-of-pearl used in the invention comprises a support comprising aluminium oxide (or alumina or A12O3; terms used interchangeably) covered at least in part by titanium oxide (or titanium dioxide; the two terms will again be used interchangeably).

[0235] Mother-of-pearl is in the form of plates.

[0236] More particularly, the particles have a shape characterized by three dimensions: a length, a width, and a height (also called thickness); the length and width being greater than the thickness. Advantageously, the ratio of the largest dimension of the wafer to the height (or thickness) of the wafer is greater than or equal to 5, more particularly greater than or equal to 20. For the purposes of the present invention, the "largest dimension" of the wafers means the diameter of the sphere in which said wafer is inscribed. The dimensions of the particles are, for example, evaluated by scanning electron microscopy and image analysis.

[0237] According to a particular embodiment, the aluminum oxide-based support of the nacre also comprises titanium dioxide. According to this embodiment, the titanium dioxide is substantially homogeneously mixed with the aluminum oxide (in other words, the titanium dioxide and the aluminum oxide are not distributed either with a concentration gradient or in the form of superimposed layers).

[0238] Moreover, advantageously, the proportion of aluminium oxide is predominant compared to that of titanium dioxide in the support.

[0239] Preferably, in the support, the titanium dioxide content represents 0.1 to 4% by weight, relative to aluminum oxide.

[0240] The aluminum oxide-based support, optionally comprising titanium dioxide, further comprises a coating at least partially comprising titanium dioxide. According to one embodiment of the invention, the coating may optionally comprise another metal, and preferably tin, also in oxide form.

[0241] More particularly, the second nacre has an average equivalent diameter (D50) in volume between 15 and 30 pm and preferably between 15 and 25 pm.

[0242] The "equivalent diameter" is the diameter of the sphere which would behave identically during the chosen particle size analysis operation.

[0243] Particle size can be measured by static light scattering using a commercial particle size analyzer such as the Malvem MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in the publication by Van de Hulst, H.C., "Light Scattering by Small Particles", Chapters 9 and 10, Wiley, New York, 1957.

[0244] Such nacres are known and are described in particular in patent US5702519, EP1013724.

[0245] They can notably be marketed under the names Timiron Glam Silver by Merck. Mother-of-pearl marketed under the names Mirinae A9001K Splendor White or Mirinae A9001S Brilliant White by CQV could also be suitable.

[0246] According to a particular embodiment of the invention, the second mother-of-pearl, if the composition includes it, is present at a content ranging from 0.05 to 12% by weight, preferably from 0.1 to 8% by weight, even more preferably from 0.15 to 4% by weight, relative to the total weight of the composition.

[0247] The weight ratio (absorbent pigment / first nacre and where applicable second nacre) can vary a wide range, advantageously ranging from 10 / 90 to 90 / 10.

[0248] More particularly, in the case of solid compositions, a weight ratio between 10 / 90 and 55 / 45 may be preferred.

[0249] More particularly in the case of liquid compositions, a weight ratio ranging from 50 / 50 to 85 / 15 may be preferred. NON-VOLATILE HYDROCARBONATED OR SILICONED OIL

[0250] As stated previously, the composition comprises at least one non-volatile polar or non-polar hydrocarbon oil, or silicone oil, and mixtures thereof.

[0251] Preferably, the content of non-volatile hydrocarbon oil(s), polar or non-polar, or silicone oil(s), and mixtures thereof, represents 10 to 70% by weight, more particularly 15 to 60% by weight, relative to the total weight of the composition.

[0252] The term "oil" refers to a liquid compound at 20°C and atmospheric pressure (1.013105 Pa), immiscible with water.

[0253] By "immiscible" is meant that the mixture of the same quantity of water and oil, after stirring, does not lead to a stable solution comprising only one phase, under the aforementioned temperature and pressure conditions. The observation is made visually or, if necessary, using a phase-contrast microscope, on 100 g of the mixture obtained after sufficient Rayneri stirring to create a vortex within the mixture (for example, 200 to 1000 rpm); the resulting mixture being left to rest, in a closed bottle, for 24 hours at room temperature before observation.

[0254] The term "hydrocarbon oil" is classically used to refer to an oil formed essentially, or even composed, of carbon and hydrogen atoms, and possibly of oxygen and nitrogen atoms, and containing no silicon or fluorine atoms. Hydrocarbon oil is therefore distinct from silicone oil and fluorinated oil. Advantageously, the hydrocarbon oils according to the invention contain only carbon, hydrogen, and oxygen atoms.

[0255] By "siliconized oil" is meant an oil comprising at least one silicon atom, in particular an oil comprising in its structure a -Si-O- group.

[0256] By "non-volatile oil" is meant an oil whose vapor pressure at 20°C is non-zero and less than 2.66 Pa, more particularly less than or equal to 0.13 Pa. By way of example, the vapor pressure can be measured according to the static method or by the isothermal thermogravimetric effusion method, according to the vapor pressure (OECD standard 104). NON-VOLATILE POLAR HYDROCARBONATE OILS

[0257] The term "polar hydrocarbon oil" means an oil formed essentially, or even composed, of carbon and hydrogen atoms, and also comprising at least one oxygen atom, and possibly nitrogen. It may contain one or more alcohol, ester, ether, carboxylic acid, amine, and / or amide groups. Such oils are therefore distinct from silicone oils since they are devoid of silicon atoms.

[0258] More particularly, the non-volatile polar hydrocarbon oil is selected from ester oils comprising one or more ester functions, possibly hydroxylated, and comprising at least one hydrocarbon group, linear or branched, saturated or unsaturated, or aromatic, the total number of carbon atoms being at least 12, as well as mixtures thereof; alcohols in the form of C10-C26; ethers of formula ROR', carbonates of formula RO(CO)OR', formulas in which, whether identical or not, the R, R' groups represent a hydrocarbon group comprising at most 16 carbon atoms, saturated or unsaturated, branched or unbranched, preferably in C3-C16; more particularly in C8-C16; as well as mixtures thereof. Ester oils

[0259] It is recalled that a polar hydrocarbon ester oil within the meaning of the invention comprises, in addition to carbon and hydrogen atoms, at least one ester function (-C(=O)-O-). The ester oil may optionally comprise other group(s) or function(s), such as, for example, one or more hydroxyl groups (-OH), one or more oxygen atoms bonded to two carbon atoms (i.e., an ether function: -O-), for example.

[0260] More particularly, the oil is chosen from among non-volatile hydrocarbon ester oils comprising one or more ester functions, possibly hydroxylated, and comprising at least one hydrocarbon group, linear or branched, saturated or unsaturated, or aromatic, the total number of carbon atoms preferably being at least 12, as well as mixtures thereof.

[0296] Among the non-volatile silicone oils, we can mention non-phenylated silicones, and phenylated silicones with or without a dimethicone fragment.

[0297] The expression "non-phenylated silicone oil" means a silicone oil that does not contain phenyl substituents.

[0361] The solid hydrocarbon compound, other than waxes, may be a pasty compound.

[0362] For the purposes of this invention, "pasty compound" means a lipophilic fatty solid compound with a reversible solid / liquid phase change, comprising, at a temperature of 20-25°C, a liquid fraction and a solid fraction. Thus, a pasty compound may have a starting melting point below 20-25°C.

[0363] The melting point of the pasty fat is determined according to the same principle as that detailed previously for waxes. In the case of a pasty compound, however, the measurement protocol is as follows:

[0364] Note that to determine the melting point of solid compounds other than waxes, the following protocol is used in particular: A 5 mg sample of pasty fat placed in a crucible is subjected to a first temperature increase from -20°C to 100°C, at a heating rate of 10°C / minute, then is cooled from 100°C to -20°C at a cooling rate of 10°C / minute and finally subjected to a second temperature increase from -20°C to 100°C at a heating rate of 5°C / minute. The melting point of said pasty fat is the temperature value corresponding to the peak of the curve representing the variation of the difference in absorbed power as a function of temperature. It should be noted that the liquid fraction by weight of the pasty fat at room temperature is equal to the ratio of the enthalpy of fusion consumed at room temperature to the enthalpy of fusion of the pasty fat. The enthalpy of fusion of a fat in a paste form is the enthalpy consumed by the fat to change from a solid to a liquid state. A fat in a paste form is said to be in a solid state when its entire mass is in crystalline solid form. A fat in a paste form is said to be in a liquid state when its entire mass is in liquid form. The enthalpy of fusion of a fat-based substance is the amount of energy required to change the fat-based substance from a solid to a liquid state. It is expressed in J / g. The enthalpy of fusion of the fat-based substance is equal to the energy generated under the curve of the resulting thermogram.

[0365] Advantageously, the content of solid hydrocarbon compound(s) at 20°C other than waxes varies from 15 to 40% by weight, relative to the total weight of the composition.

[0378] The sizes are measured by static light scattering using a commercial particle size analyzer, the Malvern Master Sizer 3000®, which allows for the determination of the particle size distribution of all particles over a wide range from 0.01 µm to 1000 µm. The data are processed based on the classical Mie scattering theory. This theory is best suited for size distributions ranging from submicron to multimicron and allows for the determination of an "effective" particle diameter. This theory is notably described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0379] D

[50] represents the maximum size that 50% of the particles have by volume.

[0380] According to one embodiment of the invention, the mineral pigment comprises a lipophilic or hydrophobic coating, the latter preferably being present in the oily phase of the composition according to the invention.

Thus, the pigments may be coated with a glutamic acid derivative and / or one of its salts, and more particularly with a stearoyl glutamate, such as aluminum stearoyl glutamate. Examples of such pigments include titanium dioxide pigments and black, red, and yellow iron oxide pigments, sold under the trade name NAI® by the company Miyoshi Kasei.

[0387] These pigments can also be in the form of composite pigments as described in patent EPI 184426. These composite pigments can be composed in particular of particles comprising an inorganic core covered at least partially with an organic pigment and at least one binder ensuring the fixation of the organic pigments on the core.

[0388] The pigment can also be a lacquer. By lacquer, we mean insolubilized dyes adsorbed onto insoluble particles, the whole thus obtained remaining insoluble during use.

[0389] The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate or calcium aluminium borosilicate, and aluminium.

[0390] Among the organic dyes, we can mention cochineal carmine. Other products known by the following names include: D&C Red 21 (CI 45 380), D&C Orange 5 (CI 45 370), D&C Red 27 (CI 45 410), D&C Orange 10 (CI 45 425), D&C Red 3 (CI 45 430), D&C Red 4 (CI 15 510), Red 6 (CI 15 850), D&C Red 33 (CI 17 200), D&C Yellow 5 (CI 19 140), D&C Yellow 6 (CI 15 985), D&C Green (CI 61 570), D&C Yellow 10 (CI 77 002), D&C Green 3 (CI 42 053), D&C Blue 1 (CI 42 090), D&C Red 22, D&C Red 28.

[0391] Examples of lacquers include the product known as D&C Red 7 (CI 15 850 :1).

[0392] In particular, the pigment content, if the composition includes any pigments, is less than or equal to 2% by weight, preferably between 0.5 and 1.5% by weight, relative to the total weight of the composition. The composition may optionally not include any such pigments.

[0393] The colouring material can also be a nacre, different from the pigment with absorbent effect and the first and second nacres described previously.

[0394] By “mother-of-pearl”, we must understand particles of any shape, iridescent or not, natural or synthesized, and which exhibit at least one color effect by optical interference.

[0395] The mother-of-pearls suitable for the invention are more particularly mother-of-pearls based on natural mica, synthetic mica, borosilicate, such as calcium aluminium borosilicate, calcium sodium borosilicate, and their combinations.

[0396] The nacre or nacres contain at least one mineral species based on at least one metal, chosen for example from iron, tin, chromium, titanium, and their combinations.

[0397] Particularly suitable are metallic oxides, such as iron, chromium, tin, titanium oxides, or even ferric ferrocyanide.

[0398] They may also include at least one organic pigment as defined above.

[0399] Nacres, different from the absorbent pigment and the first and second nacres mentioned above, can thus be chosen from white pearlescent pigments such as mica, natural or synthetic, coated with titanium or bismuth oxychloride, colored pearlescent pigments such as titanium mica with iron oxides, ferric blue, chromium oxide, titanium mica with an organic pigment of the type mentioned above, as well as pearlescent pigments based on bismuth oxychloride.

[0400] If the composition includes at least one nacre other than the pigment with absorbent effect and the first and second nacres mentioned above, the content varies more particularly between 0.1 and 2.5% by weight, relative to the total weight of the composition.

[0401] According to a first variant, if the composition is anhydrous, the content of different nacres of the pigment with absorbing effect and of the first and second nacres, represents more particularly 0.15 to 1% by weight, relative to the total weight of the composition.

[0402] According to a second variant, if the composition includes at least 5% by weight of water, relative to the total weight of the composition, the content of different nacres of the pigment with absorbing effect and of the first and second nacres, represents more particularly 0.3 to 2% by weight, relative to the total weight of the composition. CHARGES

[0403] The composition according to the invention may comprise at least one filler.

[0404] The filler is chosen from mineral fillers, organic fillers, and mixtures thereof.

[0405] The term "charge" refers to a particle of organic or mineral nature, colorless or white, solid, of any shape, insoluble in the medium of the composition at ambient temperature and atmospheric pressure. These charges are advantageously dispersed in the composition.

[0406] According to one embodiment of the invention, if the composition contains it, the content of filler(s) represents from 1 to 10% by weight, relative to the total weight of the composition. MINERAL CHARGES

[0407] The term “mineral filler” means any compound whose chemical structure does not include a carbon atom, regardless of the presence of a coating on said filler.

[0408] The fillers are in the form of particles and are distinct from the coloring materials which will be described below.

[0409] The fillers used in the compositions according to the present invention may be particles of lamellar, globular, spherical, fibrous, or any other intermediate shape between these defined forms. The fillers may be spherical, that is to say, comprising at least one generally rounded portion, in particular defining at least one portion of a sphere, preferably internally defining a concavity or a hollow (sphere, globules, bowls, horseshoe, etc.), or lamellar.

[0410] According to a particular embodiment of the invention, the charges more particularly have an average particle size (expressed as volume average diameter - D

[50] ) of at least 1 pm, preferably at least 2 pm, advantageously between 2 and 15 pm. The particle size can be measured by laser diffraction using a commercial particle size analyzer of the Mastersizer 3000 type, from Malvern. (see also ISO 13320).

[0411] The fillers used in the composition according to the invention may or may not be surface-coated, and in particular, they may be coated with a hydrophobic treatment agent, especially one that promotes the dispersion and compatibility of the filler within the composition. The hydrophobic treatment agent may be selected from silicones, in particular silanes; fluorinated derivatives; fatty acids such as stearic acid; metallic soaps such as aluminum dimyristate, aluminum salt of hydrogenated tallow glutamate; amino acids; N-acylated amino acids or their salts; lecithin, isopropyl trisostearyl titanate, and mixtures thereof. The N-acylated amino acids may comprise an acyl group having from 8 to 22 carbon atoms, such as, for example, a 2-ethylhexanoyl, caproyl, lauroyl, myristoyl, palmitoyl, stearoyl, or cocoyl group.The salts of these compounds can be aluminum, magnesium, calcium, zirconium, zinc, sodium, or potassium salts. The amino acid can be, for example, lysine, glutamic acid, or alanine. The term alkyl mentioned in the compounds cited above refers in particular to an alkyl group having from 1 to 30 carbon atoms, preferably having from 5 to 16 carbon atoms.

[0412] Such fillers may advantageously be chosen from silica (INCI name: Silica), perlite, zeolites, calcium magnesium carbonate, calcium carbonate, magnesium carbonate, magnesium hydrogen carbonate, hydroxyapatite, kaolin, talc, diatomaceous earth, natural or synthetic mica, boron nitride; silica and titanium dioxide composites, such as the TSG® series marketed by Nippon Sheet Glass, bismuth oxychloride, glass or ceramic microcapsules; such as, for example, borosilicate particles, mixtures thereof. ORGANIC LOADS

[0413] By "organic charge" means, in the sense of the invention, solid particles of at least one hydrocarbon or silicone compound, preferably hydrocarbon, regardless of their coating.

[0414] The fillers are in the form of particles and may also be surface treated or not, by means of compounds such as those described above in the context of mineral fillers.

[0415] The fillers used in the compositions according to the present invention may be of lamellar, globular, spherical, fibrous, or any other intermediate form between these defined forms. The fillers may be spherical, that is to say, comprising at least one generally rounded portion, in particular defining at least one portion of a sphere, preferably internally defining a concavity or a hollow (sphere, globules, bowls, horseshoe, etc.), or lamellar.

[0416] Suitable fillers include cellulose particles, micronized waxes, natural or synthetic, metallic soaps derived from carboxylic organic acids having 8 to 22 carbon atoms, for example, zinc, magnesium or lithium stearate, zinc laurate, magnesium myristate, polysaccharide powders, and in particular starch powders, especially corn, wheat or rice starches, crosslinked or not, starch powders crosslinked by octenylsuccinate anhydride, waxy corn starch powders, C8-C22 N-acylated amino acids with carbon atoms, for example, lauroyl lysine, and mixtures thereof.

[0417] According to a particularly advantageous embodiment of the invention, the composition, when anhydrous and solid, comprises at least one cellulose-type filler.

[0418] According to this variant, the cellulose particle content represents 2 to 10% by weight, preferably 3 to 9% by weight, relative to the total weight of the composition.

[0419] The cellulose particles usable according to the invention are preferably spherical (cellulose beads).

[0420] For the purposes of this invention, spherical particles are defined as solid or porous particles, whose surface may or may not be smooth, having an average circularity parameter of at least 0.95. The circularity parameter is defined as the ratio of the circumference of a disk having the same area as the particle to the perimeter of the particle. A value of 1 characterizes perfectly spherical particles.

[0421] The "mean circularity" can be determined by an image analysis method. In particular, the "mean circularity" can be an arithmetic mean of circularity obtained by image analysis of a scanning electron microscope (SEM) image of not less than 2000 particles observed at a magnification of 1000 by detection of secondary electrons using a scanning electron microscope (SEM).

[0422] The "circularity" of each particle is a value determined by the following formula: C = 4irS / L² where C represents a circularity, S represents an area (projected area) of the particle in the image, and L represents a length of a periphery (perimeter) of the particle in the image. As the average circularity approaches 1, the shape of each particle becomes more spherical.

[0423] They preferably have an average size (D(50) in volume) less than or equal to 40 pm, preferably ranging from 1 to 20 pm, more preferably from 2 to 15 pm.

[0424] Particle sizes can be measured by static light scattering using a commercial particle size analyzer such as the Malvem MasterSizer 2000. The data are processed based on Mie scattering theory.

[0425] Among the cellulose particles that can be used according to the invention, we can mention in particular those sold by the company Daito under the brand name Cellulobeads® such as Cellulobeads USF®, Cellulobeads USF-X®, Cellulobeads D-5®, Cellulobeads D-10®, Cellulobeads D-30®.

[0426] We can also mention, although they are not preferred, acrylic (co)polymer particles, and their derivatives, for example the polymers with the following INCI names: Methyl Methacrylate Crosspolymer, Polymethyl Methacrylate, Methyl Methacrylate / Glycol Dimethacrylate Crosspolymer, Acrylates Crosspolymer, Lauryl Methacrylate / Glycol Dimethacrylate Crosspolymer, Acrylates / Ethylhexyl Acrylate Crosspolymer, polyamide particles, such as Nylon; silicone particles, in particular silicone resin particles (e.g. Polymethylsilsesquioxane), silicone elastomer particles, in particular Vinyl Dimethicone / Methicone Silsesquioxane Crosspolymer, Diphenyl Dimethicone / Vinyl Diphenyl Dimethicone / Silsesquioxane Crosspolymer, Dimethicone / Vinyl Dimethicone Crosspolymer, Methylsilanol / Silicate Crosspolymer particles, and mixtures thereof.

[0427] Preferably, the organic filler is not chosen from silicone fillers, nor from acrylic (co)polymers, acrylonitril, polyurethane, polyamides, as described above. ETHYLCELLULOSE

[0428] The composition according to the invention may optionally include at least ethylcellulose.

[0429] Ethylcellulose is an ethyl ether of cellulose, comprising a chain made up of [3-anhydroglucose] units linked together by acetal bonds. Each An anhydroglucose unit has three replaceable hydroxyl groups, all or part of which can react according to the following reaction: RONa + C2H5Cl → ROC2H5 + NaCl, where R represents a cellulose radical. Complete substitution of the three hydroxyl groups would lead to a degree of substitution of 3 for each anhydroglucose unit, in other words, an alkoxy, specifically ethoxy, group content of 54.88%.

[0430] The ethylcellulose polymers used in a cosmetic composition according to the invention are preferably polymers having a degree of substitution in ethoxy groups, ranging from 2.5 to 2.6 per anhydroglucose unit, in other words comprising an ethoxy group content ranging from 44% to 50%.

[0431] The average molar mass of ethylcellulose is preferably chosen so that the viscosity of a 5 wt% solution in an 80 / 20 (toluene / ethanol) mixture at 25°C is from 4 to 300 mPa.s, preferably from 5 to 200 mPa.s, for example from 5 to 150 mPa.s. (ASTM D 914 standard).

[0432] The ethylcellulose used in the composition according to the invention is more particularly in powder form.

[0433] It is, for example, marketed under the trade names ETHOCEL Standard by Dow Chemicals, including ETHOCEL Standard 7 FP Premium and ETHOCEL Standard 100 FP Premium. Other commercially available products, such as those marketed by Ashland, Inc., under the names Aqualon Ethylcellulose type-K, type-N and type-T, preferably type-N, such as N7, N100, are particularly suitable for carrying out the invention.

[0434] According to a particular embodiment of the invention, the composition, when it comprises at least 5% by weight of water, relative to the total weight of the composition, also comprises ethylcellulose.

[0435] According to this variant, the ethylcellulose content represents more particularly 8 to 17% by weight, preferably 8 to 15% by weight, or even 9 to 15% by weight, and even more preferably 10 to 12% by weight, relative to the total weight of the composition. LIPOPHILE THICKENERS

[0436] The composition according to the invention may optionally include at least one lipophilic thickener, chosen more particularly from silicas, treated hydrophobic or not; lipophilic clays; alone or in mixture. SILICES

[0437] The composition according to the invention may thus include, as a mineral thickener, a fumed silica, preferably hydrophobic, or silica aerogel particles, preferably hydrophobic. Pyrogenated silica

[0438] Suitable for the invention is hydrophobically treated fumed silica. It is indeed possible to chemically modify the surface of silica by a chemical reaction that reduces the number of silanol groups present on the silica surface. In particular, silanol groups can be replaced by hydrophobic groups, resulting in hydrophobic silica.

[0439] Hydrophobic groups can be: - Trimethylsiloxyl groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. Silicas treated in this way are called "Silica Silylate" according to the CTFA (8th edition, 2000). They are marketed, for example, under the references Aerosil R812® by the company Degussa, and CAB-O-SIL TS-530® by the company Cabot. - dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are called "Silica Dimethyl Silylate" according to the CTFA (8th edition, 2000). They are marketed, for example, under the references Aerosil R972® and Aerosil R974® by the company Degussa, and CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by the company Cabot. Silica aerogels

[0440] Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

[0441] They are generally synthesized by the sol-gel process in a liquid medium and then dried, usually by extraction from a supercritical fluid, most commonly supercritical CO2. This type of drying prevents contraction of the pores and the material. The sol-gel process and the various drying methods are described in detail in Brinker CL, and Scherer GW, Sol-Gel Science: New York: Academie Press, 1990.

[0442] Hydrophobic silica aerogel particles usually have a specific surface area per unit mass (SM) of 500 to 1500 m2 / g, preferably 600 to 1200 m2 / g and better 600 to 800 m2 / g, and a size expressed as volume mean diameter (D[0,5]) of 1 to 1500 pm, better 1 to 1000 pm, preferably 1 to 1000 pm, in particular 1 to 30 pm, preferably still 5 to 25 pm, better 5 to 20 pm and better still 5 to 15 pm.

[0443] According to one embodiment, the hydrophobic silica aerogel particles used in the present invention have a size expressed in volume average diameter (D[0,5]) ranging from 1 to 30 pm, preferably from 5 to 25 pm, better from 5 to 20 pm and even better from 5 to 15 pm.

[0444] The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (BRUNAUER-EMMET-TELLER) method, described in "The Journal of the American Chemical Society", Vol. 60, Page 309, February 1938, and corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0445] The particle sizes of silica aerogel can be measured by static light scattering using a commercial particle size analyzer such as the Malvern MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows for the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0446] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (SM) ranging from 600 to 800 m2 / g and a size expressed in volume mean diameter (D[0.5]) ranging from 5 to 20 pm and even better from 5 to 15 pm.

[0447] Aerogels are hydrophobic silica aerogels, preferably silylated silica (INCI name Silica Silylate).

[0448] By "hydrophobic silica" is meant any silica whose surface is treated with silylation agents, for example with halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl Si-Rn groups, for example trimethylsilyl groups.

[0449] Regarding the preparation of surface-modified hydrophobic silica aerogel particles by silylation, reference can be made to US document 7,470,725.

[0450] Preferably, hydrophobic silica aerogel particles modified on the surface by trimethylsilyl groups will be used.

[0451] As examples of hydrophobic silica aerogels that can be used in the invention, we can cite, for example, the aerogel marketed under the name VM-2260 (INCI name Silica Silylate), by the company Dow Corning, whose particles have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0452] We can also mention the aerogels marketed by the Cabot company under the references AEROGEL TLD 201®, AEROGEL OGD 201®, AEROGEL TLD 203®, ENOVA AEROGEL MT 1100®, ENOVA AEROGEL MT 120.

[0453] We can also mention the aerogel marketed under the name VM-2270 (INCI name Silica Silylate), by the company Dow Corning, whose particles exhibit a average size ranging from 5-15 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g. LIPOPHILE CLAYS

[0454] The term “lipophilic clay” means any clay that is liposoluble or lipodispersible in the oily phase of the composition.

[0455] 'clay' means a material based on hydrated silicates and / or aluminosilicates with a lamellar structure.

[0456] Clays can be natural or synthetic and are made lipophilic by treatment with an alkyl ammonium salt such as a C22 C1O ammonium chloride, in particular steralkonium chloride or di-stearyl di-methyl ammonium chloride.

[0497] More particularly, these compounds are found in the form of salts of alkali metals such as sodium, potassium, or of amine or alkanolamine, in particular in C2-C4, primary or secondary.

[0498] These compounds generally comprise from 10 to 30 carbon atoms, in particular from 10 to 20 carbon atoms in their longest hydrocarbon chain, and are saturated or unsaturated, linear, branched or cyclic. They may further comprise up to 20 oxyalkylated motifs, preferably up to 15 motifs (in particular oxyethylated).

PREPARATION METHOD

[0510] The composition according to the invention can be prepared according to the conventional methods in the field.

[0511] When the composition is anhydrous, liquid or solid, the usual procedure is to mix the oils, waxes and solid fatty compounds at a temperature greater than or equal to the melting point of the solid fats if they are present.

[0512] Generally, if the composition includes solid compounds, the process is carried out at a temperature between 80 and 150°C, preferably between 85 and 110°C.

[0513] If the composition does not include solid compounds, a temperature close to room temperature may be appropriate.

[0514] Once the mixture has been homogenized, the absorbent pigments, the first nacres and possibly the second nacres, and where applicable, the additional coloring materials, the fillers, are then added under agitation.

[0515] For solid compositions, the mixture is then poured into molds and cooled.

[0516] The solidified compositions are then demolded and packaged.

[0517] For liquid compositions, once the mixture has been cooled if necessary, preferably under stirring, the mixture is packaged in suitable containers.

[0518] When the composition includes at least 5% by weight of water, it is more preferably in the form of a water (which represents the dispersed phase) in oil (which represents the continuous phase) emulsion.

[0519] The classic means can be implemented to prepare such a composition.

[0520] Thus, more specifically, the aqueous phase is prepared on the one hand, and on the other the oily phase of the emulsion is separated, and the two phases thus obtained are brought into contact, under sufficient agitation to obtain a homogeneous composition; the aqueous phase being preferably introduced into the oily phase.

[0521] Usually, when the composition includes it, ethylcellulose is brought into contact with the oils, and possibly the solid compounds if the composition includes them, under agitation, to obtain a homogeneous mixture.

[0522] The surfactants are then added, under stirring, to the resulting mixture.

[0523] The temperature at which the preparation of the oil phase is carried out usually varies between 25 and 110°C, preferably from 70 to 90°C, depending on the nature of the ingredients which compose it.

[0524] Advantageously, when the composition includes ethylcellulose, the preparation of the oil phase takes place at a temperature between 70 and 90°C.

[0525] The preparation of the aqueous phase generally takes place at a temperature between 40 and 90°C.

[0526] Similarly, the mixing of the two phases is carried out more particularly at a temperature below 100°C, by way of example at a temperature less than or equal to 90°C. For example, the emulsion is carried out at a temperature between 40 and 90°C.

[0527] Once the emulsion is homogenized, the filler(s) if the composition includes them are added under agitation, then the pigment with absorbent effect, the first nacres and if necessary the second nacres, until a homogeneous mixture is obtained.

[0528] The temperature at which this last step is carried out is advantageously carried out at a temperature below 50°C.

[0529] It should be noted that if the composition includes additional colouring materials different from the absorbing effect pigments, first nacres and where applicable second nacres, they can be added in the aqueous phase or in the lipophilic phase, according to their nature; or they can be added once the emulsion has been obtained, before, with or after the effect pigments / first nacres / second nacres; or even a combination of these two possibilities.

[0530] The composition is finally packaged in a suitable container.
