Abstract
Description
[0001] The subject of the present invention is a solid composition for making up keratinous substances, in particular the skin and / or the lips, comprising ethylcellulose, at least one benzoate oil, at least one liquid fatty alcohol and at least one phenylated silicone oil containing dimethicone segments in specific amounts. Another subject of the present invention is a method for making up and / or caring for the lips, in particular, comprising using such a composition.
[0002] The invention relates more particularly to a composition for making up the skin and / or lips in which it is desired to obtain a lustrous surface.
[0003] Liquid or solid anhydrous compositions especially designed for making up human keratinous substances such as the skin and lips to produce lustrous effects are obtained from mixtures comprising relatively high contents of oils, in particular non-volatile oils, and also colorants such as, for example, pearlescent agents and / or pigments.
[0004] In the case of fluid compositions, they must exhibit sufficient viscosity to ensure the stability of the composition over time, in particular to keep the colorant in suspension and to prevent the composition from flowing out of the area to be treated or made up during application. The viscosity of the composition must also limit the migration of the composition into the wrinkles and fine lines of the lip contour after application. However, this viscosity must be maintained so that the composition can be satisfactorily applied with good gliding in order to obtain a sufficiently thin and uniform deposit.
[0005] In the case of solid compositions, structurants (such as waxes, for example) are often added to the mixtures mentioned above. These compounds must harden the compositions sufficiently so that they can be molded in stick form without impairing their use properties. This is because these compositions must be able to be deconstructed so that the appropriate amount can be applied to the lips at any time. Anhydrous cosmetic compositions comprising a first oil (such as octyldodecanol) and at least one non-volatile silicone oil incompatible with the first oil and ethylcellulose are known, for example, in document WO 2017 / 108584.
[0006] These compositions make it possible to obtain a glossy deposit that remains over time. However, it would be preferred to further improve the transfer resistance of the deposit obtained, without, however, deteriorating the gloss or comfort properties of the resulting deposit, or increasing the tackiness, or introducing a feeling of tightness or dryness on the lips after application of the composition.
[0007] These and other problems are solved by the present invention, which therefore provides a solid cosmetic composition for making up and / or caring for human keratin substances, in particular the lips, comprising:
[0008] * at least ethylcellulose,
[0009] *At least one first oil selected from benzoic acid and C 8 -C 20 , preferably C 8 -C 18 Monoesters of preferably saturated monohydric alcohols and also mixtures thereof,
[0010] * At least one second oil, the at least one second oil is selected from C 10 -C 26 a polar non-volatile hydrocarbon-based oil of an alcohol and optionally an ester other than the first oil,
[0011] * at least one third oil chosen from non-volatile phenylated silicones comprising at least one dimethicone fragment,
[0012] *optionally at least one fourth oil, the at least one fourth oil being a non-phenylated silicone oil or a phenylated silicone oil without a dimethicone segment,
[0013] * The content of oil is such that the weight ratio of the first oil, the second oil and, where appropriate, the fourth oil / the third oil is less than or equal to 1.
[0014] Another subject of the invention is a method for making up human keratin substances, in particular the skin or the lips, in which the composition mentioned above is applied.
[0015] The composition according to the invention exhibits the advantages of being stable over time and easy to apply, as well as improved glide. Furthermore, the deposit obtained is precise and uniform, does not adhere and does not migrate into wrinkles and fine lines, in particular around the lips or eyes (crow's feet).
[0016] Furthermore, despite the high non-volatile oil content, the resulting deposit is fine. The deposit makes it possible to obtain a glossy make-up effect with improved wear properties. It is also comfortable, without a feeling of dryness or tightness.
[0017] Finally, the transfer resistance of the deposits obtained by applying the composition according to the invention is improved.
[0018] In the following text, the expression "at least one" is equivalent to "one or more".
[0019] Unless otherwise stated, the expressions “between… and…” and “ranging from… to…” should be understood as meaning that the limit values are included.
[0020] The temperature mentioned in this specification is at atmospheric pressure (1.013×105 Pa) shown below.
[0021] Since the composition according to the invention is a cosmetic composition, this means in particular that it comprises a physiologically acceptable medium, that is to say a medium particularly suitable for applying the composition according to the invention to human keratinous substances, most particularly the skin and the lips.
[0022] The physiologically acceptable medium is generally adapted to the nature of the support to which the composition is to be applied and also to the form in which the composition is to be packaged.
[0023] The composition according to the invention preferably comprises less than 5% by weight, more particularly less than 2% by weight, or even less than 1% by weight of water relative to the total weight of the composition. Advantageously, the composition according to the invention is anhydrous. The term "anhydrous" is understood to mean in particular that water is not intentionally added to the composition, but may be present in traces in the various compounds used.
[0024] The composition according to the invention is in solid form. The term "solid" is understood to mean in particular a composition that does not flow under its own weight at ambient temperature (25° C.) and atmospheric pressure. Preferably, the composition according to the invention is in the form of a stick. More particularly, the term "stick" is understood to mean a pharmaceutical form whose hardness can be measured according to the following "cheesewire" method:
[0025] Protocol for measuring hardness:
[0026] The compositions in stick form were stored at 20° C. for 24 hours before measuring the hardness.
[0027] The measurement is carried out at 20° C. and consists in transversely cutting the product rod, preferably a cylinder, by means of a rigid tungsten wire with a diameter of 250 μm, by moving the wire relative to the rod at a speed of 100 mm / min.
[0028] The tensile strength of the samples of the composition according to the invention in Nm was measured using a DFGS2 tensile testing device sold by Indelco-Chatillon. -1 Indicates the hardness.
[0029] The measurement is repeated three times and then averaged. The average of the three values read using the tensile tester mentioned above is given in grams (denoted as Y). This average is converted to Newtons and then divided by L (which represents the longest distance the wire passes through). In the case of a cylindrical rod, L is equal to the diameter (in meters).
[0030] The hardness is converted to Nm by the following formula -1 :(Y×10 -3 ×9.8) / L
[0031] According to this measurement method, the composition according to the invention, when it is in solid form, advantageously exhibits a relative humidity between 20 and 150 Nm at 20° C. and at atmospheric pressure. -1 Between and preferably between 40 and 120 Nm -1 The hardness between.
[0032] Ethyl cellulose
[0033] As indicated previously, the composition according to the invention comprises ethylcellulose.
[0034] Ethylcellulose is a cellulose alkyl ether comprising chains of β-anhydroglucose units linked together via acetal bonds. Each of the anhydroglucose units contains three replaceable hydroxyl groups, all or part of which can react according to the following reaction:
[0035] RONa+R'Cl ROR'+NaCl, wherein R represents a cellulose group and R' represents an ethyl group.
[0036] Full substitution of the three hydroxyl groups per anhydroglucose unit would result in a degree of substitution of 3, in other words an alkoxy content of 54.88%.
[0037] The ethylcellulose polymer used in the cosmetic composition according to the invention is preferably a polymer having a degree of substitution ranging from 2.5 to 2.6 ethoxy groups per anhydroglucose unit, in other words comprising an ethoxy content ranging from 44% to 50%.
[0038] The ethylcellulose used in the composition according to the invention is more particularly present in pulverulent form.
[0039] Ethylcellulose is sold, for example, by Dow Chemicals under the trade name Ethocel Standard (including in particular Ethocel Standard 7FP Premium and Ethocel Standard 100FP Premium). Other commercially available products, such as those sold by Ashland Inc. under the trade name Aqualon EC K-type, N-type and T-type, preferably N-type (e.g. N7, N100), are particularly suitable for carrying out the present invention.

[0049] Advantageously, the oil is immiscible with water. The term "immiscible with" is understood to mean that the mixing of equal amounts of water and oil does not produce a stable solution containing only a single phase under standard temperature and pressure conditions after stirring. If necessary, 100 g of the mixture is observed by eye or using a phase contrast microscope, the mixture being obtained after sufficient stirring with a Rayneri mixer to create a vortex in the mixture (as a guide, 200 to 1000 rpm), the resulting mixture being left to stand in a closed flask for 24 hours at ambient temperature before observation.
[0050] The term "hydrocarbon-based oil" is understood to mean an oil which is essentially formed or even consists of carbon atoms and hydrogen atoms and possibly one or more oxygen atoms and nitrogen atoms and does not contain other heteroatoms such as, for example, one or more silicon atoms. Hydrocarbon-based oils are thus different from silicone oils. Hydrocarbon-based oils may contain alcohol, ester, ether, carboxylic acid, amine and / or amide groups.

[0159] For the purposes of the present invention, the term "paste-like" means a lipophilic compound having a reversible solid / liquid state change, in particular having an anisotropic crystal structure in the solid state and comprising a liquid portion and a solid portion at ambient temperature.
[0160] In other words, the initial melting point of the pasty compound may be below ambient temperature. The liquid portion of the pasty compound measured at ambient temperature may be from 9% to 97% by weight of the pasty compound. This portion that is liquid at ambient temperature preferably accounts for 15% to 85%, more preferably 40% to 85% by weight.

[0165] It should be noted that the liquid fraction by weight of the pasty fatty substance at ambient temperature is equal to the ratio of the heat of fusion consumed at ambient temperature to the heat of fusion of the pasty fatty substance.
[0166] The heat of fusion of a pasty fatty substance is the amount of heat consumed by said substance in order to pass from the solid state to the liquid state. A pasty fatty substance is said to be in the solid state when the entire mass of the substance is in the form of a crystalline solid. A pasty fatty substance is said to be in the liquid state when the entire mass of the substance is in the form of a liquid.
[0167] The heat of fusion of a pasty fatty substance is the amount of energy required to change the pasty fatty substance from the solid state to the liquid state. The heat of fusion is expressed in J / g. The heat of fusion of a pasty fatty substance is equal to the area under the curve of the thermogram obtained.

[0190] The term "pigment" means white or colored mineral or organic particles which are insoluble in the medium of the composition and which are intended to color and / or opacify the resulting composition and / or deposit. Pigments are therefore not fillers.
[0191] According to a first particular embodiment, the pigments used are chosen from mineral pigments.
[0192] The term "mineral pigment" means any pigment that meets the definition in the chapter on inorganic pigments in Ullmann's encyclopaedia. Among the mineral pigments that can be used in the invention, mention may be made of zirconium oxide or cerium oxide, and also zinc oxide, iron oxides (black, yellow or red) or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and iron blue, titanium dioxide, and metal powders (for example aluminum powder or copper powder).

[0194] According to one particular form of the invention, the pigment has a size characterized by D
[50] greater than 100 nm and possibly ranging up to 10 μm, preferably from 200 nm to 5 μm and more preferably from 300 nm to 1 μm.
[0195] These sizes were obtained using a commercial MasterSizer from Malvern. The particle size analyzer measures by static light scattering, which makes it possible to determine the size distribution of all these particles over a wide range (which can extend from 0.01 μm to 1000 μm). The data are processed based on the standard Mie scattering theory. This theory is most applicable to size distributions ranging from submicron to multimicron; it allows the determination of the "effective" particle diameter. This theory is described in particular in the following publications: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.
[0196] D
[50] represents the maximum dimension present at 50% by volume of the particles.

[0200] The pearlescent agent can be selected from pearlescent pigments such as mica titanium coated with iron oxide, mica titanium coated with bismuth oxychloride, mica titanium coated with chromium oxide, mica titanium coated with organic dyes and also pearlescent pigments based on bismuth oxychloride. These pearlescent agents can also be mica particles on the surface of which at least two layers of metal oxides and / or organic colorants are superimposed in sequence.

[0203] Among the pigments that can be used according to the invention, mention may also be made of those pigments having optical effects other than simple conventional coloring effects, i.e. uniform and stabilized effects as produced by conventional colorants (e.g. monochromatic pigments). For the purposes of the present invention, the term "stabilized" means an effect that lacks color variability with viewing angle or in response to temperature changes.
[0204] For example, this material can be chosen from particles with metallic hues, goniochromatic colorants, diffractive pigments, thermochromics, optical brighteners, and also fibers, especially interference fibers. Needless to say, these different materials can be combined in order to provide two effects at the same time, or even novel effects according to the invention.

[0208] The coating may also comprise at least one additional non-lipophilic compound.
[0209] For the purposes of the present invention, "coating" of a pigment according to the present invention generally means a total or partial surface treatment of the pigment with a surfactant which absorbs, adsorbs or grafts onto the pigment.
[0210] The surface treated pigments can be prepared according to surface treatment techniques of a chemical, electrical, mechanochemical or mechanical nature well known to those skilled in the art. Commercial products can also be used.
[0211] Surfactants can be absorbed, adsorbed or grafted onto the pigment by evaporation of solvent, chemical reaction and formation of covalent bonds.
[0212] According to one variant, the surface treatment consists in applying a pigment.
[0213] The coating may represent from 0.1% to 20% by weight and in particular from 0.5% to 5% by weight relative to the total weight of the coated pigment.
[0214] The coating can be produced, for example, by absorbing a liquid surfactant onto the surface of the solid particles by simply mixing the particles with said surfactant under stirring, optionally with heating, before incorporating the particles into the other ingredients of the cosmetic or care composition.
[0215] The coating can be produced, for example, by chemical reaction of the surfactant with the surface of the solid pigment particles and formation of covalent bonds between the surfactant and the particles. This method is described in particular in patent US Pat. No. 4,578,266.
[0216] Chemical surface treatment may involve diluting the surfactant in a volatile solvent, dispersing the pigment in this mixture, and then slowly evaporating the volatile solvent so that the surfactant is deposited on the surface of the pigment.
[0217] When the pigment comprises a lipophilic or hydrophobic coating, this coating is preferably present in the fatty phase of the composition according to the invention.

[0270] If the composition according to the invention contains a filler, the content of this filler advantageously represents from 0.5% to 15% by weight and more particularly from 2% to 10% by weight relative to the weight of the composition.
[0271] Mineral thickener
[0272] The composition according to the invention may also comprise at least one mineral thickener chosen from optionally modified clays, optionally modified silicas or mixtures thereof.
[0273] More particularly, if the composition contains a mineral thickener, the content of this mineral thickener, expressed as active material, is from 0.1% to 10% by weight and preferably from 0.2% to 5% by weight relative to the total weight of the composition.
[0274] Optionally modified clay
[0275] Clays are silicates containing cations which may be selected from the group consisting of calcium, magnesium, aluminum, sodium, potassium and lithium cations and mixtures thereof.
[0276] As examples of such products, mention may be made of clays of the montmorillonite group and also of the vermiculite, stevensite or chlorite group. These clays may be of natural or synthetic origin.
[0277] Preferably, organophilic clays are used, more particularly modified clays such as montmorillonite, bentonite, hectorite, attapulgite or sepiolite and mixtures thereof. The clay is preferably bentonite or hectorite.
[0278] These clays are modified with compounds selected from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkylaryl sulfonates or amine oxides and mixtures thereof.
[0279] Mention may thus be made of hectorites modified with quaternary amines, more particularly of C 2+ containing or not containing aromatic groups. 10 To C 22 Fatty acid halogenated (e.g. chloride) ammonium modified, such as hectorites modified with distearyldimethylammonium halide (preferably chloride) (CTFA name: disteardimethylammonium hectorite), such as those sold under the names Bentone 38V, Bentone 38V CG or Bentone EW CE by Elementis, or stearalkonium chloride hectorites, such as in particular the product Bentone 27V.

[0281] According to a preferred embodiment, the thickener is chosen from organophilic modified clays, in particular organophilic modified hectorites, in particular modified with benzyldimethylammonium stearate or distearyldimethylammonium halide (in particular chloride).
[0282] According to an alternative form of the invention, the content of optionally modified clay ranges from 0.2% to 10% by weight relative to the weight of the composition, preferably from 0.5% to 5% by weight relative to the weight of the composition. These percentages are expressed as active material.
[0283] Optionally modified silica
[0284] Mention may also be made of fumed silica, preferably treated to be hydrophobic on the surface, the size of the particles of which is advantageously less than 1 μm. In fact, the surface of the silica can be chemically modified by a chemical reaction, thereby causing a reduction in the number of silanol groups present at the surface of the silica. In particular, the silanol groups can be replaced by hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups can be:
[0285] - trimethylsiloxy groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. According to the CTFA (6th edition, 1995), silicas treated in this way are called silylated silicas (Silica Silylate). They are sold, for example, by Degussa under the reference number Aerosil and Cab-O-Sil Sale.
[0286] - dimethylsiloxy or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. According to the CTFA (6th edition, 1995), silicas treated in this way are called "silica dimethyl silylate". They are marketed, for example, by Degussa under the reference number Aerosil and Aerosil and Cab-O-Sil and Cab-O-Sil Sale.
[0287] The hydrophobic fumed silica particularly has a particle size that may be nanometer-sized to micrometer-sized, for example ranging from about 5 to 200 nm.
[0288] The composition according to the invention may also comprise at least silica aerogel particles.
[0289] Silica aerogel is a porous material obtained by replacing the liquid component of silica gel with air (through drying).
[0290] These aerogels are typically synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the most commonly used supercritical fluid being supercritical CO. 2 This type of drying makes it possible to avoid shrinkage of pores and materials. The sol-gel process and the various drying operations are described in detail in Brinker CJ and Scherer GW, Sol-Gel Science, New York, Academic Press, 1990.
[0291] Hydrophobic silica aerogel particles suitable for practicing the present invention exhibit a range of from 500 to 1500 m 2 / g, preferably from 600 to 1200m 2 / g and even better from 600 to 800m 2 The specific surface area per unit mass (S M ), and a size expressed as a volume average diameter (D[0.5]) ranging from 1 to 1500 μm, better still from 1 to 1000 μm, preferably from 1 to 100 μm, in particular from 1 to 30 μm, more preferably from 5 to 25 μm, better still from 5 to 20 μm and even better still from 5 to 15 μm.
[0292] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a diameter ranging from 600 to 800 m 2 The specific surface area per unit mass (S M ) and a size denoted as volume mean diameter (D[0.5]) ranging from 5 to 20 μm and even better still from 5 to 15 μm.
[0293] The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (Brunauer-Emmett-Teller) method, which is described in The Journal of the American Chemical Society, Vol. 60, p. 309, February 1938 and corresponds to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of the particles under consideration.
[0294] The size of the silica aerogel particles can be measured by static light scattering using a commercial particle size analyzer such as the MasterSizer 2000 machine from Malvern. The data are processed based on the Mie scattering theory. This theory is accurate for isotropic particles, making it possible to determine the "effective" particle size in the case of non-spherical particles. This theory is particularly described in the following publication: Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.
[0295] According to a preferred embodiment, the hydrophobic silica aerogel particles used in the present invention have a diameter ranging from 5 to 60 μm. 2 / cm 3, preferably from 10 to 50m 2 / cm 3 And also better from 15 to 40m 2 / cm 3 The specific surface area per unit volume S V .
[0296] Aerogels that can be used according to the invention are hydrophobic silica aerogels, preferably silylated silica (INCI name: Silica Silylate).
[0297] With regard to the preparation of hydrophobic silica aerogel particles which have been surface-modified by silylation, reference may be made to US Pat. No. 7,470,725.
[0298] Hydrophobic silica aerogel particles surface-modified with trimethylsilyl groups will preferably be used.
[0299] As hydrophobic silica aerogels that can be used in the present invention, examples that may be mentioned include the aerogels sold by Dow Corning under the name VM-2260 (INCI name: Silica Silylate), the particles of which have an average size of about 1000 microns and a diameter ranging from 600 to 800 microns. 2 / g of specific surface area per unit mass.
[0300] Mention may also be made of the products manufactured by Cabot Corporation under the reference numbers Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, Aerogels are sold as Aerogel MT 1100 and Enova Aerogel MT 1200.
[0301] It will be preferred to use an aerogel sold by the company Dow Corning under the name VM-2270 (INCI name: SILICA SILYLATED), the particles of which have an average size ranging from 5 to 15 microns and a particle size ranging from 600 to 800 m 2 / g of specific surface area per unit mass.
[0302] Preferably, when the composition comprises at least one thickener chosen from optionally modified silicas, the optionally modified silicas are chosen from hydrophobic silica aerogel particles.
[0303] According to an alternative form of the invention, the content of optionally modified silica ranges from 0.5% to 15% by weight and preferably from 1% to 7% by weight relative to the weight of the composition. These values are expressed as weight of active material.
[0304] Preferably, the mineral thickener is chosen from organophilic clays, in particular modified hectorites; hydrophobically treated fumed silicas; hydrophobic silica aerogels; or mixtures thereof, and more particularly also at least one organophilic modified clay or at least one hydrophobically modified silica, in particular hydrophobic silica aerogels.
[0305] Optional additives
[0306] The composition may comprise at least one optional additive selected from, for example, film formers; antioxidants; preservatives; fragrances; flavoring agents; neutralizers; emollients; organic thickeners, such as, for example, linear or branched dextrin esters; coalescing agents; humectants; vitamins; and mixtures thereof.
[0307] Of course, a person skilled in the art will carefully choose the optional additional additives and / or their amounts such that the advantageous properties of the composition according to the invention are not or not substantially adversely affected by the envisaged additions.
[0308] The following examples serve to illustrate the present invention without however limiting its scope.
