[0006] BACKGROUND ART

[0007] Imparting texture to keratinous substances, such as skin, is one of the key features of cosmetic products, especially skin cosmetic products.

[0008] In particular, a refreshing feel (as the cosmetic product bursts, allowing liquid to flow out, in other words, a transformation of a physical property like from a gel / cream to a liquid) by a structural collapse during application, and no sticky feeling after application are often required for consumer satisfaction.

[0009] In addition, a gel with a unique sherbet-like appearance can provide a visually refreshing impression that matches the above transformative texture and no sticky skin finish.

[0028] The present invention also relates to a cosmetic process for treating a keratin substance, comprising the step of applying the composition according to the present invention.

[0029] BEST MODE FOR CARRYING OUT THE INVENTION

[0030] After diligent research, the inventors have discovered that it is possible to provide a composition which can provide a sherbet-like appearance as well as texture transformation (from the texture of a gel / cream to the texture of a liquid) during application and no sticky feeling after application.

[0031] Thus, one aspect of the present invention is a composition comprising:

[0032] (a) at least one neutralized poly(meth)acrylic acid polymer;

[0033] (b) at least one organic acid or salt thereof; and

[0034] (c) water, wherein the amount of the (a) neutralized poly(meth)acrylic acid polymer is 0.5% by weight or more, relative to the total weight of the composition.

[0035] The composition according to the present invention can provide a sherbet-like appearance as well as texture transformation (from the texture of a geVcream to the texture of a liquid) during application and no sticky feeling after application. The term “sticky” here means a property which provides a tacky feeling to the skin. Thus, the composition according to the present invention can provide both a refreshing visual impression and a refreshing feeling to touch. Thus, the composition according to the present invention can provide a unique appearance and texture.

[0036] The composition according to the present invention can also provide additional effects.

[0037] In general, a composition including an organic acid or a salt thereof may have difficulty in being thickened and may have a low viscosity. Therefore, in order to thicken such a composition including an organic acid or a salt thereof, a large amount of a thickener tends to be added to the composition.

[0038] However, the use of a large amount of a thickener in a composition may negatively influence the texture transformation of the composition or may cause sticky feeling to touch. In addition, if a thickener is a synthetic polymer, the use of a large amount of the thickener may cause the formation of noodles after application due to the aggregation of the synthetic polymers.

[0039] The composition according to the present invention includes (b) organic acid or salt thereof.

[0040] Therefore, the composition according to the present invention may include a large amount of the (a) neutralized poly(meth)acrylic acid polymer(s) in order to sufficiently thicken the composition.

[0041] However, even if the composition according to the present invention includes a large amount of the (a) neutralized poly(meth)acrylic acid polymer(s), the composition according to the present invention can cause good texture transformation and no sticky feeling after application. In addition, the composition according to the present invention can suppress the formation of noodles after application.

[0042] Furthermore, the composition according to the present invention is stable. The composition according to the present invention is stable just after the preparation of the composition and a long time after the preparation of the composition, even under elevated temperature. Therefore, the composition according to the present invention is stable over time, and can be stored for a long period of time even under hot conditions, for example, in summer.

[0062] The (a) neutralized poly(meth)acrylic acid polymer may be crosslinked.

[0063] The closslinking of the (a) neutralized poly(meth)acrylic acid polymer may be performed by, for example, applying at least one crosslinking agent to the (a) neutralized poly(meth)acrylic acid polymer by spraying.

[0064] In one preferred embodiment of the present invention, the (a) neutralized poly(meth)aciylic acid polymer is a crosslinked homopolymer.

[0079] It is known that AHA activates the protease in the stratum corneum to enhance the degradation of comeodesmosomes, while in the dermis layer, the AHA can promote collagen formation, which subsequently leads to desquamation of skin. In addition, it has been reported that AHA also decreases facial pores and blackheads, most likely by targeting enzyme activation and protein functions linked to sebum production.

[0080] It is known that BHA adds keratolytic activity which promotes the peeling and shedding of cells in the stratum corneum layer. It also decongests the skin by softening the sebum which blocks the pores. For this reason, it is effective for improving desquamation and especially effective for acne and oily skin types as well.

[0107] (Oil-Absorbable Particle)

[0108] The composition according to the present invention may comprise (e) at least one oil-absorbable particle. If two or more oil-absorbable particles are used, they may be the same or different.

[0109] The (e) oil-absorbable particle is capable of absorbing (and / or adsorbing) an oil or a liquid fatty substance, for instance sebum (from the skin).

[0110] It is preferable that the (e) oil-absorbable particle have an oil-absorbing capacity of 140 ml / 100 g or more, more preferably 250 ml / 100 g or more, even more preferably 400 ml / 100 g or more, further more preferably 600 ml / 100 g or more, even further more preferably 800 ml / 100 g or more, and further still more preferably 1000 ml / 100 g or more.

[0113] The amount of oil absorbed (and / or adsorbed) by the (e) oil-absorbable particle may be characterized by measuring the wet point according to the method described below. The oilabsorbing capacity measured at the wet point, noted Wp, corresponds to the amount of oil that needs to be added to 100 g of particle in order to obtain a homogeneous paste.

[0114] The amount of the absorbed (and / or adsorbed) oil can be measured according to the method for determining the oil uptake of a powder described in standard ISO 787 / 5-1980.

[0115] An amount m (in grams) of the (e) oil-absorbable particle of between about 0.5 g and about 5 g (the amount depends on the density of the (e) oil-absorbable particle, but typically 2 g) is placed on a glass plate and isononyl isononanoate is then added drop wise.

[0116] After the addition of 4 to 5 drops of isononyl isononanoate, the isononyl isononanoate is incorporated into the (e) oil-absorbable particle using a spatula, and addition of the isononyl isononanoate is continued until a conglomerate of isononyl isononanoate and powder has formed. At this point, the isononyl isononanoate is added one drop at a time and the mixture is then triturated with the spatula. The addition of isononyl isononanoate is stopped when a firm, smooth paste is obtained. This paste must be able to be spread on the glass plate without cracking or forming lumps. The volume Vs (expressed in ml) of isononyl isononanoate used is then noted.

[0117] The oil uptake corresponds to the ratio Vs / m.

[0118] In the above protocol to determine the wet point, isononyl isononanoate may be replaced with oleic acid or linseed oil. Unless otherwise defined, oil-absorbing capacities defined in the present invention mean those measured by using isononyl isononanoate.

[0119] The (e) oil-absorbable particle may have a volume-average particle size of less than 50 pm, preferably less than 45 pm, and more preferably less than 40 pm.

[0120] The (e) oil-absorbable particle may have a volume-average particle size of 1 pm or more, preferably 2 pm or more, more preferably 3 pm or more, and even more preferably 4 pm or more.

[0121] The (primary) particle size of the (e) oil-absorbable particle may be from 1 to 30 pm, preferably from 2 to less than 25 pm, more preferably from 3 to less than 20 pm, and even more preferably from 4 to less than 15 pm. The (primary) particle size can be measured by, for example, extracting and measuring from a photograph image obtained by SEM and the like, using a particle size analyzer such as a laser diffraction particle size analyzer, and the like. It is preferable to use a particle size analyzer such as a laser diffraction particle size analyzer. In this ease, the (primary) particle size is the volume-average (primary) particle size.

[0122] It is preferable that the (e) oil-absorbable particle be a porous particle, in particular, a porous spherical particle.

[0123] According to another aspect of the present disclosure, the (e) oil-absorbable particle may have a BET specific surface area greater than or equal to 300 m2 / g, for instance, greater than or equal to 500 m2 / g, such as greater than or equal to 600 m2 / g, and less than or equal to 1500 m2 / g.

[0124] The (e) oil-absorbable particle may have a density of from 0.01 to 0.9 g / cm3, preferably from 0.05 to 0.5 g / cm3, and more preferably from 0.1 to 0.3 g / cm3.

[0125] The (e) oil-absorbable particle may be organic or inorganic.

[0126] Inorganic Oil-Absorbable Particle:

[0127] The (e) oil-absorbable particle may be of inorganic nature.

[0128] The inorganic (e) oil-absorbable particle may have at least one inorganic core and at least one hydrophobic coating.

[0129] The hydrophobic coating may be formed by a hydrophobic treatment agent which may be chosen especially from fatty acids such as stearic acid; metal soaps such as aluminium dimyristate, the aluminium salt of hydrogenated tallow glutamate; amino acids; N-acylamino acids or salts thereof; lecithin, isopropyl triisostearyl titanate, mineral waxes, and mixtures thereof.

[0130] The N-acylamino acids may comprise an acyl group containing from 8 to 22 carbon atoms, for instance a 2-ethylhexanoyl, caproyl, lauroyl, myristoyl, palmitoyl, stearoyl, or cocoyl group. The salts of these compounds may be aluminium, magnesium, calcium, zirconium, zinc, sodium, or potassium salts. The amino acid may be, for example, lysine, glutamic acid, or alanine.

[0131] The term "alkyl" mentioned in the compounds mentioned previously especially denotes an alkyl group containing from 1 to 30 carbon atoms and preferably containing from 5 to 16 carbon atoms.

[0132] It is preferable that the inorganic (e) oil-absorbable particle comprise at least one material selected from the group consisting of silica, particularly hydrophobic silica such as silica silylate, silicate, perlite, boron nitride, magnesium carbonate, magnesium hydroxide, kaolin, talc, and a mixture thereof.

[0133] The hydrophobic silica, particularly silica silylate, may be based on silica aerogels which are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

[0134] They are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the one most commonly used being supercritical CO2. This type of drying makes it possible to avoid shrinkage of the pores and of the material. The sol-gel process and the various drying operations are described in detail in Brinker C.J. and Scherer G.W., Sol-Gel Science, New York, Academic Press, 1990. The hydrophobic silica aerogel particles may exhibit a specific surface area per unit of 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 the 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, further more preferably from 5 to 20 pm, and even further more preferably from 5 to 15 pm.

[0135] According to one embodiment, the hydrophobic silica aerogel particles may exhibit 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.

[0136] The specific surface area per unit of weight can be determined by the nitrogen absorption method, known as the BET (Brunauer-Emmett-Teller) method, described in The Journal of the American Chemical Society, Vol. 60, page 309, February 1938, which corresponds to international standard ISO 5794 / 1 (appendix D). The BET specific surface area corresponds to the total specific surface area of the particles under consideration.

[0137] The sizes of the silica aerogel particles can be measured by static light scattering using a commercial particle size analyzer of MasterSizer 2000 type from Malvern. 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 publication by Van de Hulst, H.C., "Light Scattering by Small Particles”, Chapters 9 and 10, Wiley, New York, 1957.

[0138] According to an advantageous embodiment, the hydrophobic silica aerogel particles may exhibit a specific surface area per unit of weight (SW) ranging from 600 to 800 m2 / g and a size, expressed as the volume-average diameter (D[0.5]), ranging from 5 to 20 pm, and preferably from 5 to 15 pm.

[0139] The silica aerogel particles can advantageously exhibit 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.

[0140] In the context of the present invention, this density, known as the packed density, can be assessed according to the following protocol:

[0141] 40 g of powder are poured into a graduated measuring cylinder; the measuring cylinder is then placed on a Stav 2003 device from Stampf Volumeter; the measuring cylinder is subsequently subjected to a series of 2500 packing actions (this operation is repeated until the difference in volume between 2 consecutive tests is less than 2%); and the final volume Vf of packed powder is then measured directly on the measuring cylinder. The packed density is determined by the ratio w / Vf, in this instance 40 / Vf (Vf being expressed in cm3and w in g).

[0142] According to one embodiment, the hydrophobic silica aerogel particles may exhibit a specific surface area per unit of volume SV ranging from 5 to 60 m2 / cm3, preferably from 10 to 50 m2 / cm3, and more preferably from 15 to 40 m2 / cirf. The specific surface area per unit of volume is given by the relationship: Sv = Sw x p; where p is the packed density expressed in g / cm3and Sw is the specific surface area per unit of weight expressed in m2 / g, as defined above.

[0143] The term "hydrophobic silica" is understood to mean any silica, the surface of which is treated with silylating agents, for example with halogenated silanes, such as alkylchlorosilanes, siloxanes, particularly dimethylsiloxanes, such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl groups Si-Rn, for example, trimethylsilyl groups.

[0144] As regards the preparation of hydrophobic silica aerogel particles modified at the surface by silylation, reference may be made to the document US 7 470 725.

[0145] Use will particularly be made of hydrophobic silica aerogel particles modified at the surface with trimethylsilyl groups.

[0293] Yes: Sherbet-like appearance was observed

[0294] No: Sherbet-like appearance was not observed

[0295] (Texture Transformation)

[0296] Five professional panelists evaluated “texture transformation” at early stage of application during the application of the compositions according to Examples 1-6 and Comparative Examples 1-3. Each panelist took each composition in their hands, then applied it onto their faces to evaluate texture transformation at early stage of application, and graded it from 1 (poor) to 5 (very good), which was then classified in the following 4 categories based on the average of the grade:

[0297] Very Good: From 5.0 to 4.0 (Texture transformation (from gel to liquid) is clearly felt at the early stage of application)

[0298] Good: From 3.9 to 3.0 (Texture transformation was felt at the early stage of application)

[0299] Poor: From 2.9 to 2.0 (Texture transformation was hardly felt at the early stage of application) Very Poor: From 1 .9 to 1 .0 (Texture transformation was not felt at all at the early stage of application)

[0300] The results are shown in Table 1 .

[0301] (Non-Sticky Feeling)

[0302] Five professional panelists evaluated “non-sticky feeling” after application of the compositions according to Examples 1-6 and Comparative Examples 1-3. Each panelist took each composition in their hands, then applied it onto their faces to evaluate non-sticky feeling after application, and graded it from 1 (poor) to 5 (very good), which was then classified in the following 4 categories based on the average of the grade:

[0303] Very Good: From 5.0 to 4.0 (Stickiness was not felt at all after application)

[0304] Good: From 3.9 to 3.0 (Stickiness was hardly felt after application)

[0305] Poor: From 2.9 to 2.0 (Stickiness was felt after application)

[0306] Very Poor: From 1.9 to 1 .0 (Stickiness was clearly felt after application)

[0307] The results are shown in Table 1 .

[0308] (Noodle)

[0309] Five professional panelists evaluated “formation of noodle” after application of the compositions according to Examples 1 -6 and Comparative Examples 1 -3. Each panelist took each composition in their hands, then applied it onto their faces to evaluate the formation of noodle after application, and graded it from 1 (poor) to 5 (very good), which was then classified in the following 4 categories based on the average of the grade: Very Good: From 5.0 to 4.0 (No noodle was observed at all)

[0310] Good: From 3.9 to 3.0 (Noodle was slightly formed such that it was not perceivable at normal usage) Poor: From 2.9 to 2.0 (Small noodle was observed and it could be perceived)

[0311] Very Poor: From 1 .9 to 1 .0 (Large noodle was observed and it could be perceived)

[0312] (Temperature Stability)

[0313] Each of the compositions according to Examples 1 -6 and Comparative Examples 1 -3 was filled into a glass bottle and was held at a temperature of 45°C for 2 months. Each sample was then investigated for the degree of change (aspect, odor and color), and evaluated in accordance with the following criteria:

[0314] Very Good: Almost the same conditions as at production.

[0315] Good: Little change in aspect, odor or color was observed.

[0316] Poor: Change in aspect, odor or color was clearly observed. Aspect change (e.g., phase separation and creaming), bad odor, or color change (e.g., yellowing and browning) was clearly observed.

[0317] Very Poor: A remarkable change in aspect, odor or color was noticed. A remarkable aspect change (e.g., phase separation and creaming), bad odor, or color change (e.g., yellowing and browning) was observed.

[0318] The results are shown in Table 1.

[0319] (Viscosity)

[0320] The viscosity of each of the compositions according to Examples 1-6 and Comparative Examples 1-3 was measured by using a B-type viscometer (Rotor: No. 4, rotation speed: 6 rpm, and measurement time: 1 minute).

[0321] The results are shown in Table 1 .

[0322] (Summary)

[0323] The compositions according to Examples 1-6 showed a sherbet- like appearance as well as texture transformation (from the texture of a gel / cream to the texture of a liquid) during application and no sticky feeling after application.

[0324] The compositions according to Examples 1-6 were also stable and were able to suppress the formation of noodles.

[0325] The comparison between Example 1 and Example 2 demonstrates that the addition of oil- absorbable particle (silica silylate) further improved non-sticky feeling to touch.

[0326] Comparative Example 1 shows that no use of any thickener could not increase the viscosity of the composition according to Comparative Example 1. In addition, the composition according to Comparative Example 1 was unstable and could not show any sherbet-like appearance, texture transformation, good non-sticky feeling.

[0327] Comparative Example 2 shows that the use of non-neutralized poly(meth)acrylic acid polymer could not provide any sherbet-like appearance, good texture transformation, or non-sticky feeling. In addition, the composition according to Comparative Example 2 could not suppress the formation of noodles. Comparative Example 3 shows that the use of a very small amount of neutralized poly(meth)acrylic acid polymer (0.3% by weight) was insufficient to increase the viscosity of the composition according to Comparative Example 3 and to provide the composition with a sherbetlike appearance, good texture transformation, or good non-sticky feeling. In addition, the composition according to Comparative Example 3 was not stable.
