Description

Title of the invention: Cosmetic composition comprising at least one clay, at least one crystallizable fat, and at least one liposoluble UV filter

[0001] The present invention relates to compositions, in particular cosmetics comprising, in a physiologically acceptable aqueous medium, at least one clay selected from phyllosilicates having a 2:1 sheet structure, at least one crystallizable fat, and at least one liposoluble filter capable of absorbing UVA and / or UVB.

[0002] It is known that radiation with wavelengths between 320 nm and 400 nm allows the human epidermis to tan, while radiation with wavelengths between 280 and 320 nm, known as UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental change in the biomechanical properties of the epidermis, resulting in the appearance of wrinkles and leading to premature skin aging.

[0003] It is also known that UVA rays with a wavelength between 320 and 400 nm penetrate the skin more deeply than UVB rays. UVA rays cause immediate and persistent tanning of the skin. Daily exposure to UVA rays, even for short periods, under normal conditions can damage collagen and elastin fibers, resulting in changes to the skin's microrelief, the appearance of wrinkles, and uneven pigmentation (spots, lack of uniformity of complexion).

[0004] To date, a wide variety of photoprotective compositions are already known to protect keratinous materials, and more specifically the skin, against the harmful effects induced by UVA and / or UVB radiation. They are generally presented in the form of direct or inverse emulsions in which the liquid oil phase contains the liposoluble UV filters. However, these compositions generally present uncomfortable or even unpleasant sensory aspects, notably a greasy and sticky feeling, which are significant.

[0005] Consequently, there is a need for a photoprotective composition based on a liposoluble UV filter which has good cosmetic properties upon application, in particular that is easy to apply, without a greasy or sticky finish on the skin, especially after drying.

[0006] There is also a need for a photoprotective composition based on a liposoluble UV filter limiting the adhesion of particles.

[0007] There also remains a need for a photoprotective composition based on Liposoluble UV filter offering a sensory experience without a greasy or sticky finish on the skin while providing a high level of UV protection.

[0008] The inventors have surprisingly discovered that the combination of a clay chosen from among the phyllosilicates having a 2:1 sheet structure and at least one crystallizable fat makes it possible to eliminate or reduce the stickiness of such a photoprotective composition, which limits the adhesion of particles, while maintaining a high level of protection against UVA and / or UVB.

[0009] More specifically, the present invention relates to a composition, particularly a cosmetic one, comprising, in a physiologically acceptable aqueous medium:

[0010] - at least one clay selected from among the phyllosilicates having a sheet-like structure 2:1,

[0011] - at least one crystallizable fat, and

[0012] - at least one liposoluble filter capable of absorbing UVA and / or UVB.

[0013] The present invention also relates to a cosmetic treatment method non-therapeutic application of keratinous materials, preferably of the skin, comprising the application to said keratinous materials of a composition according to the invention.

[0014] Clay selected from among the phyllosilicates having a 2:1 sheet structure

[0015] The composition according to the invention comprises at least one clay selected from among the phyllosilicates having a 2:1 sheet structure. The classification of clays is referenced in the following work: Bergaya F., Lagaly G. “Handbook of Clay Science” 2nd Edition. A. Fundamentals — Elsevier Ltd., 2013.

[0016] Phyllosilicates are minerals of the silicate group constructed by stacking tetrahedral layers (“T”) where the tetrahedra share three out of four vertices (the “basal” oxygens), the fourth vertex (the “apical” oxygen) being connected to an octahedral layer (“O”) occupied by different cations. In phyllosilicates having a TOT structure, an octahedral O layer is sandwiched between two tetrahedral T layers.

[0017] The 2:1 sheet structure is also called the TOT structure, where T is a tetrahedral layer and O is an octahedral layer.

[0018] Preferably, the clay is chosen from among the smectites.

[0019] The structure of smectites differs from other phyllosilicates with a 2:1 sheet structure by the presence of an interlayer space between each TOT sheet association, which depends on the hydration state of the clay, and in which interlayer cations are intercalated. Smectites are sometimes called "swelling" clays. Preferably, the interlayer cations are selected from Ca2+, Mg2+, Na+, and Li+.

[0020] Preferably, the clay is chosen from trioctahedral smectites.

[0021] Trioctahedral smectites are characterized by the fact that all the octahedral sites The helical sites of the TOT structure are mainly occupied by divalent cations. Preferably, the divalent cations of the octahedral sites are chosen from Mg2+ and Fe2+.

[0022] In particular, the clays according to the invention are trioctahedral smectites that can be exfoliated or “activated” in the presence of water, thus forming aqueous gels due to the existence of interlayer cations within the structure.

[0023] When water comes into contact with a clay suitable for the invention, it hydrates the clay's layers, thereby inducing swelling of the distance between the layers. Then, separation of the layers occurs, possibly via an exfoliation and / or delamination mechanism. An aqueous gel is then obtained. Essentially, a content of this specific type of clay, ranging from 0.5% to 10% by weight relative to the total weight of the composition, is what allows the formation of gelled aqueous phases in the compositions according to the invention.

[0024] Preferably, the clay according to the invention comprises an amount by weight of SiO2 greater than or equal to 30% relative to the total weight of the clay, preferably between 35% and 65% by weight, and an amount by weight of MgO greater than or equal to 10%, preferably between 15% and 30% by weight.

[0025] According to a more preferred embodiment, the clay according to the invention comprises 35% to 65% by weight of SiO2, relative to the total weight of the clay, and 15% to 30% by weight of MgO, relative to the total weight of the clay.

[0026] Preferably, in the clay according to the invention, the SiO2 / MgO weight ratio is between 1 and 3, preferably between 1.5 and 2.5, preferably between 1.8 and 2.4.

[0027] Preferably, the clay according to the invention further comprises a quantity by weight of Al2O3 between 0% and 15% relative to the total weight of the clay.

[0028] According to a first variant, a clay suitable for the invention is devoid (devoid) of A12O3.

[0029] According to a second variant, a clay suitable for the invention may comprise from 0.1% to 15% by weight of Al2O3, preferably from 8% to 12% by weight, relative to the total weight of the clay.

[0030] According to another preferred embodiment, when T A12O3 is present within the clay suitable for the invention, the SiO2 / A12O3 weight ratio is strictly greater than 3.

[0031] Preferably, the clay according to the invention has a density of less than 2.7. Density (or specific gravity) is a very important property of minerals; its calculation is quite simple. It is dimensionless and measured using various apparatus and techniques that are covered in most mineralogy textbooks. Among these methods, the Jolly balance and the beam balance are best suited for working with mineral samples. The apparatus for performing these measurements is simple and can be built inexpensively (Sinkankas, 1966). Density corresponds to the The following calculation:

[0032] [Math.l] Density = (weight in air) / (weight in air - weight in water).

[0033] According to a particular embodiment, a clay suitable for the invention has the following general molecular formula: [CO-U] ^"^3+ M*f'“o20(OH)4 X^nthO

[0035] in which

[0036] M4+ represents a cation, preferably Si4+,

[0037] M3+ represents a cation, preferably Al3+,

[0045] The clay suitable for the invention is generally available in powder form.

[0046] Preferably, the clay is chosen from the group consisting of hectorite, stevensite and saponite.

[0047] Advantageously, the clay is hectorite.

[0048] Hectorite can be defined by the following formula: Nax(Mg3.x,Lix)Si4Oio(OH)2, x being between 0.2 and 0.4, preferably equal to 0.3.

[0049] Preferably, the clay of the composition according to the invention is different from sauconite, sobotkite, talc and montmorillonite.

[0050] Preferably, the clay according to the invention is an unmodified clay. By unmodified clay, we mean a natural or synthetic clay that has not undergone any modification whatsoever. For example, when an unmodified clay suitable for the invention is an unmodified hectorite, this is distinct from hectorites modified with a C22 fatty acid ammonium chloride, such as hectorite modified with distearyl dimethyl ammonium chloride. In one embodiment, an unmodified clay suitable for the invention is synthetic.

[0051] According to a preferred embodiment, an unmodified clay suitable for the invention is natural, preferably natural hectorite.

[0052] Modified clay is defined as sheet silicates whose lipophilicity has been increased, for example by ion-exchange reactions with quaternary ammonium salts, preferably quaternary ammonium chlorides. The chlorides Quaternary ammonium compounds include, for example, benzyldimethylstearylammonium chloride, or quaternium-18, with the formula

[0053] [Chem.2] R1 . I R1—N—CHj CH3 cr in which the R1 groups are independently selected from among the linear saturated C12-C20 alkyl groups. Modified clays are for example disteardimonium hectorite or stearalkonium hectorite.

[0054] Preferably, the composition according to the invention is substantially free of modified clay, preferably substantially free of disteardimonium hectorite and stearalkonium hectorite. By "substantially free" is meant that the composition comprises less than 0.1% by weight relative to the total weight of the composition, preferably less than 0.05% by weight, preferably less than 0.01% by weight of modified clay. Preferably, the composition according to the invention is completely free of modified clay.

[0055] Preferably, the clay is present in a content of between 0.1% and 10% by weight relative to the total weight of the composition, preferably between 0.5% and 5% by weight, preferably between 1% and 3% by weight, advantageously between 1.5% and 2.5% by weight.

[0171] Example 2: Anti-adhesion test of compositions Cl, C2 and C3 according to the invention and of comparative compositions C4*, C5*, C6* and C7*

[0172] The non-stickiness of compositions Cl, C2 and C3 according to the invention and of comparative compositions C4*, C5*, C6* and C7* was evaluated according to the following protocol:

[0173] - Bioskin plates (reference: MAPREKOS Bioskin K520 or K531 plate A4) smooth and fiat surface thickness 2mm (in squares 5*5 cm) are rinsed with a detergent solution (micellar solution, surfactant solution) then with water and are left to dry for 2 hours in an oven at 40°C.

[0174] - 40 to 60 mg of each composition are applied to a Bioskin plaque. The spreading is done according to the following procedure: the formula is first spread using a finger cot with right-to-left movements (5 back-and-forth motions), then the tray is rotated a quarter turn and 5 more back-and-forth motions are performed. The operation is repeated on all 4 sides of the tray.

[0175] - The plates are weighed to ensure that they contain at least 30 mg of composition.

[0176] - Each plate is left to dry for at least 20 minutes on a plate heated (reference: EKIUM PCMF 400*600).

[0177] - hydrophobic black iron oxide (FeO) particles are applied using a A sieve is used to ensure uniform particle size, and the quantity of particles is precisely measured using a precision balance. The plate is left to rest for 15 minutes to allow the particles to adhere.

[0178] - the plate is then placed on a rotating support, an airflow is then introduced function for 5 seconds using a compressor set to 0.2 bar (reference: Compressors Smart Jet Pro 875 by IWATA) and an airbrush positioned 30 cm from the plate (reference: Aerograf IWATA HP-G5 (0.5 mm) so that the sample is swept by this flow transversely.

[0179] - the plate is then weighed again in order to identify the quantity of particles having adhered to the formulaic film.

[0180] A composition is considered non-sticky when the percentage of FeO removed during the passage of the Skin FX support under the airflow is greater than or equal to 70%.

[0181] The results of this test are presented in the following table:

[0182] [Tables2] Composition Amount of FeO deposited (mg) Amount of FeO remaining after airflow (mg) Percentage of FeO removed by airflow Cl 30.3 8.1 74% C2 66.2 12.8 80.5% C3 38.1 5.4 85.8% C4* 51.1 43 15.8% C5* 24.1 8.5 48.2% C6* 44.6 31.7 28.9% C7* 73.8 54.9 25%

[0183] When the compositions do not contain unmodified clay and / or crystallizable fats (comparative compositions C4*, C5*, C6* and C7*), the adhesion of the iron oxide is significant because the compositions are sticky. Only the compositions according to the invention comprising the combination of an unmodified clay and a crystallizable fat (compositions C1, C2 and C3) make it possible to obtain non-sticky compositions.

[0184] Example 3: Other compositions according to the invention and comparative

[0185] Another composition according to the invention C8 and another comparative composition C9* were prepared according to the following protocol:

[0186] 1) The oily phase, containing crystallizable fats as well as lipo- filters solubles and a first surfactant, is introduced into the tank and heated to 80°C (emulsifier speed at 400 rpm scraper 20 rpm).

[0187] 2) When all the solid raw materials are melted, the clay or gum gellan is added to be dispersed in this oily phase (emulsifier speed 400 rpm; coaxial 90 rpm; scraper 50 rpm).

[0188] 3) The aqueous phase containing the second surfactant, the water-soluble filters and The water is prepared separately and heated to 80°C in a 5L Maxilab (Olsa brand) tank.

[0189] 4) The aqueous phase is added to the oily phase (emulsifier speed at 4000 rpm) ; coaxial 150 rpm; scraper 75 rpm). After 15 minutes, sodium alginate, when present, is added (emulsifier speed 4000 rpm; coaxial 150 rpm; scraper 75 rpm).

[0190] 5) After 10 minutes, the heating is stopped and the system cools to a setpoint temperature of 10°C. At the same time, the charge is introduced into the mixture (emulsifier speed 2000 rpm; coaxial 150 rpm; scraper 75 rpm).

[0191] 6) At 40°C, the preservative and antioxidants are added, at 30°C the rest of the conservatives are added.

[0192] 7) If necessary, the pH is adjusted according to the hydrophilic UV filters used.

[0193] The SPF index of the compositions was determined according to the ISO standard method 24442.
