Description

DescriptionAqueous sorbet composition comprising an (alkyl)acrylic acid polymer, a polysaccharide and a colorant, and cosmetic process employing it

[0001] The present invention relates to a preferably cosmetic composition comprising i) at least one polymer derived from (Ci-Ce)alkyl acrylic acid and salts thereof, ii) at least one polysaccharide, iii) at least one colorant, and iv) water, to the use of said composition in cosmetics, and to a process for treating keratin materials by applications of said composition to said materials.Technical field

[0002] There is great interest in providing texture to keratin materials, especially human keratin materials such as the skin, for cosmetic products. A further aim is to provide compositions which are pleasant in texture, more particularly of gel / cream or even "sorbet" type, with particular sensations, especially refreshing sensations, as soon as the compositions are applied.

[0003] In addition to the provision of compositions with a pleasant texture of the gel / cream or even "sorbet" type, an aim is that, after application to the keratin materials, there should be excellent coverage and little or no color after application to said materials.

[0004] The idea is to find a composition, especially a cosmetic composition, which, after massage, allows the liquid to flow out, by transformation of a physical property, such as of a gel / cream into a liquid. Ideally, the transformation would take place during the application of said composition. It would then be advantageous if, once the application had been carried out on said materials, there was no need to lament a sensation of stickiness or drying-out of said materials thus treated.

[0005] These technical problems have been solved by the composition according to the invention.

[0006] Hence the subject of the invention is a composition, especially a cosmetic composition, comprising: i) at least one polymer derived from (Ci-Ce)alkyl acrylic acid and salts thereof, comprising a repeating unit of formula (I):[Chem. 1]-[CH(R1)-C(R2)(COO M*)]- in which formula (I):* R1and R2, which are identical or different, represent a hydrogen atom or a (Ci-Ce)alkyl group such as methyl, preferably R1and R2represent a hydrogen atom,* M+represents a cationic counterion, preferably an alkali metal, alkaline earth metal or ammonium, more preferably M+represents an alkali metal such as sodium;* y represents an integer greater than or equal to 2;* z is zero, or represents a number greater than zero; preferably y > z; ii) at least one linear or branched polysaccharide, preferably branched, more particularly comprising the combination of monosaccharides chosen from glucose, mannose and glucuronic acid, combined or not with a (keto)(Ci-Ce)alkyl carboxylic acid such as pyruvic acid or such as xanthan gum; iii) at least one colorant, more particularly a dye and / or pigment, absorbing in the visible spectrum and / or at least one pigment, preferably black such as carbon black, Yellow 5, Red 33, Blue 1 ; and iv) water.

[0007] Also a subject of the invention is the use of the cosmetic composition, in particular in caring for keratin materials, more particularly human keratin materials such as the skin.

[0008] Another subject of the invention is a process for treating keratin materials, especially human keratin materials such as the skin, by applying the composition according to the invention to said materials.

[0009] The composition of the invention has excellent rheology and is very pleasant to the touch. Once applied to keratin materials, in particular human keratin materials such as the skin, the composition transforms into a gel with an appearance similar to a "sorbet" with a refreshing sensation. In addition, the keratin materials, once treated with the composition of the invention, are not sticky and the color disappears on application or immediately after being applied to said keratin materials, and especially the skin.

[0010] Moreover, the composition of the invention remains stable over time even at a temperature greater than or equal to 45°C after several weeks, and even after one month or even two months.

The test tube is 16 cm high and 1.6 cm in diameter and filled to 14 cm (the bottom of the meniscus of the composition in the tube is at 14 cm from the bottom of the tube). A published international patent application (A4 format) is placed 1 cm behind the tube. The observer's eyes are positioned at a distance (reading focal length relative to the test tube) of between 20 cm and 40 cm, such as 30 cm, perpendicular to the middle of the composition in the tube (approximately 7 cm from the bottom of the tube). The observer then assesses whether they can distinctly read the published international patent application through the composition in the tube, specifically the first page. It is understood that the tester has normal vision, or uses corrective eyewear (glasses, contact lenses, or other optical devices) as needed for reading. For example, one can use application WO 2018 / 104428 and evaluate the clarity, i.e. , the ability to read all 31 lines on page 13, or preferably, perform the reading test on the first page.

[0049] Spectrophotometric Method:

[0062] The neutralized polymer(s) i) can be neutralized totally or partially. Preferably, the polymer(s) i) is (are) partially neutralized, preferably by a metal salt, more preferably by an alkali metal salt, and even more preferably a sodium salt.

[0063] According to a particular embodiment, in the polymer or polymers of the invention, the molar ratio of the neutralized parts (units of formula (I)) to the non-neutralized parts (units of formula (II)) is at least 10%, particularly at least 20%, more particularly at least 30%, even more particularly at least 40%, or even at least 50% and / or particularly at most 90%, more particularly at most 80%, even more particularly at most 70%, better still at most 60%.

[0064] According to a particular embodiment of the invention, the composition comprises one or more polymers i) as defined above comprising (preferably consisting of) a repetition of unit of formula (I) and of unit (II) in which R1and R2represent a hydrogen atom or a (Ci- C4)alkyl group such as methyl, preferably a hydrogen atom.

[0065] According to one particular embodiment of the invention, the composition comprises one or more polymers i) as defined above in which M+represents a cationic counterion chosen from an alkali metal, alkaline earth metal and ammonium; preferably M+represents an alkali metal such as sodium.

[0066] The polymer(s) i) as defined above is (are) particularly chosen from "superabsorbents", i.e., the polymer(s) is (are) capable of absorbing at least 20 times its (their) weight of water (i.e., at least 20 grams of water absorbed per gram of superabsorbent polymer - the water absorbence characteristics being defined at room temperature: 25°C and atmospheric pressure (1 atm) with distilled water), more particularly at least 50 times its (their) weight of water, more particularly capable of absorbing at least 80 times its (their) weight of water; preferably the polymer(s) of formula (I) is (are) capable of absorbing at least 100 times its (their) weight of water.

[0067] The water absorption capacity value of the polymer(s) can be determined, for example, by dispersing 5 grams (g) of polymer(s) in 150 g of water and waiting for 5 minutes (min.) to 30 min., such as 20 min., filtering the solution through a 150 mm filter in 20 min., and weighing the unabsorbed water.

[0069] When discussing water absorption capacity, it is understood that the polymer(s), after absorbing distilled water, maintain their structure, meaning that even after absorbing the maximum amount of water, the saturated polymer(s) retain a defined, non-liquid shape. This can be tested, for example, by placing 10g of the superabsorbent polymer(s) to be evaluatedin a becher (beaker) and adding 200g of distilled water. After mixing, or even sonication, a "spatula-full" of the mixture is taken from the becher. The spatula is then rotated to 90° above the beaker and held still without moving. The time it takes for the mixture to remain on the spatula without dripping or falling back into the beaker is measured. If, after at least 5 seconds, better at least 10 seconds, even better at least 20 seconds, and preferably at least 30 seconds, nothing falls from the spatula into the becher, then the absorption capacity is considered to be reached. After absorbing the maximum amount of water, the polymer(s) preferably exhibit an opaque or translucent appearance. If adding 1 or 2g of additional distilled water results in a more liquefied mixture, and when the previous experiment is repeated with the spatula rotated to 90° and held still above the becher without moving, and at least one drop of the mixture falls within 5 seconds, better within 10 seconds, even better within 20 seconds, and preferably within 30 seconds, then the maximum water absorption capacity is considered to be reached, which in this case is 20 times its weight. The upper limit is thus found and will be 20 times its weight in water.

[0256] Hydrophobic silica, in particular silica silylate, is in particular constituted on the basis of silica aerogels, i.e., porous materials, obtained by replacing (in particular by drying or other means for evaporating solvent, in particular water) the liquid component of a silica gel with air. They are generally synthesized by a sol-gel process in liquid medium and then dried, most often by extraction with a supercritical fluid, the most commonly used being supercritical CO2. This type of drying avoids shrinkage of the pores and the material. The sol-gel process and the various drying operations are known to those skilled in the art. Mention may be made, for example, of the method described in detail in the work by Brinker C.J. and Scherer G.W., Sol-Gel Science, New York, Academic Press (1990).

[0257] The hydrophobic silica aerogel particle(s) may have a specific surface area per unit weight (SW) ranging from 500 to 1500 m2 / g, preferably from 600 to 1200 m2 / g, and more preferably from 600 to 800 m2 / g, and / or a size, expressed as a volume-average diameter (D[0.5]), ranging from 1 to 1500 pm, preferably from 1 to 1000 pm, more preferably from 1 to 100 pm, particularly from 1 to 30 pm, even more preferably from 5 to 25 pm, even more preferably from 5 to 20 pm, and even more preferably from 5 to 15 pm.

[0258] According to a particular embodiment of the invention, the hydrophobic silica aerogel particle(s) may have a size, expressed as volume-average diameter (D[0.5]), ranging from 1 to 30 pm, preferably from 5 to 25 pm, more preferably from 5 to 20 pm, and even more preferably from 5 to 15 pm.

[0259] The specific surface area per unit weight can be determined by the nitrogen absorption method, called the BET (Brunauer-Emmett-Teller) method, described in the scientific publication J. Amer. Chem. Soc., vol. 60, p. 309 (1938), which 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.

[0260] The sizes of the silica aerogel particle(s) can be measured by static light scattering using a granulometer, for example using a Malvern MasterSizer 2000-type commercial granulometer. The data are processed on the basis of the Mie scattering theory. This theory, which is exact for isotropic particles, makes it possible to determine, in the case of non- spherical particles, an "effective" particle diameter. This theory is described in particular in the scientific work of Van de Hulst, H.C., "Light Scattering by Small Particles", chap. 9 and 10, Wiley, New York (1957).

[0261] According to an advantageous embodiment, the hydrophobic silica aerogel particle(s) may have a specific surface area per unit weight (SW) ranging from 600 to 800 m2 / g and a size, expressed as volume-average diameter (D[0.5]), ranging from 5 to 20 pm, and preferably from 5 to 15 pm.

[0262] The silica aerogel particle or particles can advantageously have a packed density (r) ranging from 0.04 g / cm3to 0.10 g / cm3, and preferably from 0.05 g / cm3to 0.08 g / cm3.

[0263] In the context of the present invention, this density, called packed density, can be measured according to the following protocol: 40 g of powder are poured into a measuring cylinder. The cylinder is then placed on a Stampf Volumeter Stav 2003 apparatus; then subjected to a series of 2500 tamping or compacting operations (this procedure is repeated until the difference in volume between 2 consecutive tests is less than 2%). The final volume Vf of compacted powder is then measured directly on the measuring cylinder. The packed density is determined by the ratio w / Vf, in this case 40 / Vf (Vf being expressed in cm3and w in g).

[0264] According to one embodiment, the hydrophobic silica aerogel particles may have a specific surface area per unit volume SV ranging from 5 to 60 m2 / cm3, preferably from 10 to 50 m2 / cm3, and more preferably from 15 to 40 m2 / cm3.

[0265] The specific surface area per unit volume is given by the relation: SV = SW x p; where p is the packed density expressed in g / cm3and SW is the specific surface area per unit weight expressed in m2 / g, as defined above.

[0266] The term "hydrophobic silica" is understood to mean any silica whose surface is treated with silylating agents, for example with halogenated silanes, such as halosilanes, in particular alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes, such as hexamethyldisiloxane, or silazanes, so as to functionalize OH groups with silyl groups - Si(R')3, with R', identical or different, representing a hydrogen atom or a linear or branched, acyclic or cyclic, saturated or unsaturated, aromatic or non-aromatic hydrocarbon group, comprising from 1 to 14 carbon atoms, optionally interrupted by one or more heteroatoms such as oxygen; preferably, the hydrocarbon group is chosen from (Ci-Ce)alkyl, aryl such as phenyl, and aryl(Ci-Ce)alkyl such as benzyl; preferably, R' represents a (Ci-C4)alkyl group such as methyl.

[0267] As regards the preparation of hydrophobic silica aerogel particles surface-modified by silylation, reference may be made to the document US 7,470,725.

[0268] Hydrophobic silica aerogel particles surface-modified with -Si(R')3 groups as defined above, preferably trimethylsilyl, will be used in particular.

[0395] The composition according to the invention may comprise one or more butters, which may be identical or different, preferably of plant origin.

[0396] According to a preferred embodiment of the invention, the weight content, in the butter or butters according to the invention, of C16 fatty acids of the triglycerides, expressed with respect to all the fatty acids of the triglycerides, is less than 23%.

[0397] For the purposes of the present invention, the term “butter1’ (also known as a “pasty fatty substance”) means a lipophilic fatty compound which undergoes a reversible solid / liquid change of state and which includes, at a temperature of 25°C and at atmospheric pressure (760 mmHg), a liquid fraction and a solid fraction. In other words, the starting melting point of the pasty compound may be less than 25°C. The liquid fraction of the pasty compound, measured at 25°C, may represent 9% to 97% by weight of the compound. This fraction that is liquid at 25°C preferably represents between 15% and 85%, more preferably between 40% and 85%, by weight.

[0398] Preferably, the butter(s) have an end melting point of less than 60°C.

[0399] Preferably, the butter(s) have a hardness of less than or equal to 6 MPa.

[0400] Preferably, the pasty fatty substances have, in the solid state, an anisotropic crystal organization, which is visible by X-ray observation.

[0401] For the purposes of the invention, the melting point corresponds to the temperature of the most endothermic peak observed on thermal analysis (DSC) as described in the standard ISO 11357-3; 1999. The melting point of a pasty substance or of a wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name DSC Q2000 by the company TA Instruments.

[0402] As regards the measurement of the melting point and the determination of the end melting point, the sample preparation and measurement protocols are as follows:

[0403] A sample of 5 mg of pasty fatty substance, preheated to 80°C and withdrawn with magnetic stirring using a spatula that is also heated, is placed in a hermetic aluminium capsule, or a crucible. Two tests are performed to ensure the reproducibility of the results.

[0404] The measurements are performed on the calorimeter mentioned above. The oven is flushed with nitrogen. Cooling is performed by an RCS 90 heat exchanger. The sample is then subjected to the following protocol, being first heated to 20°C and then subjected to a first temperature rise from 20°C to 80°C at a heating rate of 5°C / minute, then cooled from 80°C to -80°C at a cooling rate of 5°C / minute and finally subjected to a second temperature rise from -80°C to 80°C at a heating rate of 5°C / minute. During the second temperature rise, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the sample of butter is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.

[0405] The end melting point corresponds to the temperature at which 95% of the sample has melted.

[0406] The liquid fraction by weight of the butter at 25°C is equal to the ratio of the heat of fusion consumed at 25°C to the enthalpy of fusion of the butter.

[0407] The heat of fusion of the pasty compound is the heat consumed by the compound in order to pass from the solid state to the liquid state. The butter is said to be in the solid state when all of its mass is in crystalline solid form. The butter is said to be in the liquid state when all of its mass is in liquid form.

[0408] The heat of fusion of the butter is equal to the integral of the entire melting curve obtained using the abovementioned calorimeter, with a temperature rise of 5 or 10°C / minute, according to the standard ISO 11357-3:1999. The heat of fusion of the butter is the amount of energy required to make the compound change from the solid state to the liquid state. It is expressed in J / g.

[0409] The heat of fusion consumed at 25°C is the amount of energy absorbed by the sample to change from the solid state to the state that it has at 25°C, constituted of a liquid fraction and a solid fraction.

[0410] The liquid fraction of the butter measured at 32°C preferably represents from 30% to 100% by weight of the compound, preferably from 50% to 100%, more preferably from 60% to 100% by weight of the compound. When the liquid fraction of the butter measured at 32°C is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32°C.

[0411] The liquid fraction of the butter measured at 32°C is equal to the ratio of the heat of fusion consumed at 32°C to the heat of fusion of the pasty compound. The heat of fusion consumed at 32°C is calculated in the same way as the heat of fusion consumed at 23°C.

[0412] As regards the measurement of the hardness, the sample preparation and measurement protocols are as follows:

[0413] The composition according to the invention or the butter is placed in a mold 75 mm in diameter, which is filled to about 75% of its height. In order to overcome the thermal history and to control the crystallization, the mold is placed in a Vdtsch VC0018 programmable oven, where it is first placed at a temperature of 80°C for 60 minutes, then cooled from 80°C to 0°C at a cooling rate of 5°C / minute, and then left at the stabilized temperature of 0°C for 60 minutes, and then subjected to a temperature rise ranging from 0°C to 20°C, at a heating rate of 5°C / minute, and then left at the stabilized temperature of 20°C for 180 minutes.

[0414] The compression force measurement is taken using a TA / TX2i texturometer from Swantech. The spindle used is chosen according to the texture:- cylindrical steel spindle 2 mm in diameter for starting materials which are very rigid;- cylindrical steel spindle 12 mm in diameter for starting materials which are not very rigid.The measurement involves three steps:- a first step after automatic detection of the surface of the sample, where the spindle moves at a measuring speed of 0.1 mm / second, and penetrates into the composition according to the invention or the butter to a penetration depth of 0.3 mm, and the software notes the maximum force value reached;- a second step, known as relaxation, where the spindle remains in this position for one second and the force is noted after 1 second of relaxation; and finally- a third step, known as withdrawal, where the spindle returns to its original position at a speed of 1 mm / second, and the withdrawal energy of the spindle (negative force) is noted.

[0415] The hardness value measured during the first step corresponds to the maximum compression force measured in newtons divided by the area of the texturometer cylinder expressed in mm2in contact with the butter or the composition according to the invention. The hardness value obtained is expressed in megapascals or MPa.
