Description

Cosmetic composition comprising a cucurbic acid compound and an acrylic semicrystalline polymer

The present invention relates to a cosmetic composition in oil-in-water emulsion form comprising a cucurbic acid compound and a semicrystalline acrylic polymer, and also to the use of this composition in a process for treating human keratin materials.

More particularly, the composition of the invention is intended for caring for and/or making up keratin materials.

For the purposes of the invention, the term "keratin materials" is intended to denote, for example, the skin, mucous membranes, the lips, the scalp, the eyelashes, the eyebrows and the hair. Patent application EP-A-1 333 021 discloses hydrogenated cucurbic acid compounds such as 3-hydroxy-2-pentylcyclopentaneacetic acid for promoting desquamation of the skin and stimulating epidermal renewal, combating the signs of ageing of the skin, improving the radiance of the complexion and/or making facial skin smooth. In patent application FR-A-62921255, these compounds are also described for their use as depigmenting agents.

However, introducing these hydrogenated cucurbic acid compounds into an oil- in-water emulsion gives rise to instability of the composition, especially after storage for one month, or even two months at 45°C: the emulsion then shows phase separation of oil at the surface; the oil globules dispersed in the aqueous phase have a coarse aspect, making the emulsion non-uniform.

The aim of the present invention is thus to provide an oil-in-water emulsion comprising the hydrogenated cucurbic acid compound that is stable and homogeneous, especially after storage for one month, or even two months at 45°C. The inventor has discovered that such a stable emulsion can be obtained by using a particular semicrystalline acrylic polymer. More specifically, the present invention relates to a composition in the form of an oil-in-water emulsion, comprising a cucurbic acid compound of formula (I) as described below, an oily phase comprising a semicrystalline polymer chosen from Cio-C₃₀ alkyl (meth)acrylate homopolymers, and an aqueous phase. The composition according to the invention is in particular a cosmetic composition.

Surprisingly, the inventor has observed that the addition of a cucurbic acid compound to a composition comprising a semicrystalline polymer as described previously does not significantly affect the viscosity of the said composition and thus enables it to be formulated in a form that is suited to its handling during its application.

According to yet another of its subjects, the present invention relates to a non- therapeutic treatment process for caring for or making up keratin materials, comprising the application to the said keratin materials of a composition in accordance with the invention. The process is in particular intended for care or makeup treatment of the skin. The cucurbic acid-based compound is a compound chosen from those corresponding to formula (I) below:

in which: Ri represents a radical COOR₃, R₃ denoting a hydrogen atom or a Ci-C₄ alkyl radical, optionally substituted with one or more hydroxyl groups;

R₂ represents a saturated or unsaturated linear hydrocarbon-based radical containing from 1 to 18 carbon atoms or a saturated or unsaturated branched or cyclic hydrocarbon-based radical containing from 3 to 18 carbon atoms; and also the optical isomers thereof, and the corresponding salts.

Preferably, Ri denotes a radical chosen from -COOH, -COOMe, -COO-CH₂- CH₃, -COO-CH₂-CH(OH)-CH₂OH, -COOCH₂-CH₂-CH₂OH and -COOCH₂- CH(OH)-CH₃. Preferentially, Ri denotes a radical -COOH.

Preferentially, R₂ denotes a linear, saturated or unsaturated hydrocarbon- based radical, preferably containing from 2 to 7 carbon atoms. In particular, R₂ may be a pentyl, pentenyl, hexyl or heptyl radical.

According to one embodiment, the compound of formula (I) is chosen from 3- hydroxy-2-[(2Z)-2-pentenyl]cyclopentaneacetic acid and 3-hydroxy-2- pentylcyclopentaneacetic acid. Preferably, compound (I) is 3-hydroxy-2- pentylcyclopentaneacetic acid; this compound may especially be in the form of the sodium salt.

The salts of the compounds that may be used according to the invention are chosen in particular from salts of alkali metals, for example sodium or potassium; salts of alkaline-earth metals, for example calcium, magnesium or strontium; metal salts, for example zinc aluminium, manganese or copper; ammonium salts of formula NH₄ ⁺; quaternary ammonium salts; salts of organic amines, for instance salts of methylamine, dimethylamine, trimethylamine, triethylamine, ethylamine, 2-hydroxyethylamine, bis(2-hydroxyethyl)amine or tris(2-hydroxyethyl)amine; lysine or arginine salts. Salts chosen from sodium, potassium, magnesium, strontium, copper, manganese and zinc salts are preferably used. The sodium salt is preferentially used. The compound of formula (I) defined previously may be present in the composition according to the invention in a content ranging from 1 % to 10% by weight, and preferably from 1 ,5% to 5% by weight, relative to the total weight of the composition.

The composition according to the invention comprises a semicrystalline polymer chosen from Ci₀-C₃₀ alkyl (meth)acrylate homopolymers.

For the purposes of the invention, the term "polymers" means compounds comprising at least two repeating units, preferably at least three repeating units and more especially at least ten repeating units.

For the purposes of the invention, the term "semicrystalline polymer" means polymers comprising at least one crystallizable side chain with a first-order reversible change of phase temperature, in particular of melting (solid-liquid transition).

For the purposes of the invention, the expression "crystallizable chain" means a chain comprising at least 10 carbon atoms and which, if it were alone, would change from the amorphous state to the crystalline state reversibly, depending on whether one is above or below the melting point. For the purposes of the invention, a "chain" is a group of atoms, which are pendent or lateral relative to the polymer backbone. A semicrystalline polymer that is suitable for use in the invention may in particular have a melting point higher than the temperature of the skin.

According to one particular embodiment, a semicrystalline polymer with crystallizable side chains that is suitable for use in the invention may have a melting point of less than or equal to 80°C, in particular in a range from 30°C to 70°C, in particular from 40°C to 65°C, more particularly from 42°C to 60°C, or better still from 44°C to 56°C, or even from 44°C to 54°C, and more particularly less than 50°C.

This melting point (Tm) may be measured by any known method and in particular using a differential scanning calorimeter (DSC).

According to one particular embodiment of the invention, the polymer may be chosen from homopolymers resulting from the polymerization of a monomer with a crystallizable side chain chosen from saturated Ci₀ to C₃₀ alkyl (meth)acrylates, which may be represented by formula (II) below:

in which is H or CH₃, R represents a Ci₀ to C₃₀ alkyl group and X represents 0.

According to a more particular embodiment of the invention, the polymer is derived from the polymerization of monomers with a crystallizable chain chosen from saturated Ci₀ to C₃₀ alkyl (meth)acrylates, and more particularly homopolymers resulting from the polymerization of a monomer with a crystallizable chain chosen from Ci₄-C₂₄ alkyl acrylates and Ci₄-C₂₄ alkyl methacrylates.

As a particular example of a semicrystalline polymer that may be used in a composition according to the invention, mention may be made of the Intelimer™ products from the company Landec described in the brochure "Intelimer™ Polymers", Landec IP22. These polymers are in solid form at room temperature. They bear crystallizable side chains and correspond to saturated Ci₄-C₂₄ alkyl acrylate or methacrylate homopolymers. As semicrystalline polymers that are suitable for the compositions according to the present invention, mention may also be made of the stearyl acrylate homopolymer, such as the product sold under the name Intelimer^® IPA 13-1 from the company Landec or from the company Air Products and Chemicals, or the behenyl acrylate homopolymer (such as Intelimer^® IPA-13.6) (INCI name: Poly C10-30 alkyl acrylate).

The semicrystalline polymer may be present in the composition according to the invention in an amount ranging from 0, 1 % to 3% by weight, relative to the total weight of the composition. Preferably, the content of the said polymer may range from 0, 1 % to 2,5% by weight relative to the total weight of the composition.

Preferentially, the content of the said polymer may range from 0,2% to 2% by weight relative to the total weight of the composition.

The composition comprises an aqueous phase.
