Description

Title of the invention: Cosmetic composition of the oil-in-water emulsion type with a powdery appearance Technical field

[0001] The present invention relates to the field of cosmetic care compositions, in particular in the form of oil-in-water emulsions, and providing interesting sensory properties when applied and dried on a keratin material.

[0002] By “keratin material” is meant in particular the skin, the scalp, keratin fibers such as the eyelashes, the eyebrows, the hair, and the body hair, the nails, the mucous membranes such as the lips, and more particularly the skin (body, face, neck, décolleté, eye contour, eyelids). Prior art

[0003] The galenic forms conventionally used to provide a powdery feel are solid compositions comprising powdery materials such as loose or pressed powders, the latter also being called compact. These galenic forms are particularly appreciated by users, given their lightness, softness and non-sticky or greasy feel.

[0004] This type of powdery feel composition also exists in the form of a direct emulsion, namely an oily phase dispersed in an aqueous phase. These compositions have the advantage of providing a similar or even more suitable sensoriality for skin care and, above all, of providing a perception of freshness and comfort upon application. They are also conducive to rapid evaporation of the liquid medium carrying the powdery materials.

[0005] On the other hand, with regard to these direct emulsion type compositions, there is a need to maintain their stability, in particular by limiting the phase shift phenomenon after manufacture, when particulate materials, such as powdery materials, are incorporated therein at a high charge rate. Among the particulate materials of these compositions generally are materials such as hydrophobic silicas and / or lauroyl lysine type particles, of a lipophilic nature. Due to their lack of affinity or low affinity for water, these particulate materials have the advantage of being more compatible with the architecture of direct emulsions, but the physicochemical stability of these emulsions does not remain optimal. Furthermore, the galenic formulas incorporating these materials do not provide users with an immediate perception of marked, soft and slippery powderiness, in particular during its drying and / or after drying on the skin.But this is precisely what users expect.

[0006] Furthermore, with regard to these direct emulsion type compositions, there is a need to improve their appearance on the skin after application, in particular by limiting the formation of white traces on the skin, in particular when particulate materials, such as powdery materials, are incorporated therein at a high charge rate.

[0007] Thus, the present invention aims to develop a galenic formula capable of providing users with an almost immediate perception of powderiness upon application.

[0008] It also aims to offer a composition providing its users with feelings of lightness, softness and a non-sticky or greasy appearance to the touch.

[0009] It also aims to provide a composition whose appearance after application to the skin is improved, in particular for which the formation of white traces on the surface of the skin after application is limited or even avoided.

[0010] Finally, the invention also aims to propose a galenic formula with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good index of naturalness and / or of natural and / or abundant origin. Indeed, the formulation of environmentally friendly cosmetic products, that is to say, the design and development of which take environmental issues into account, is becoming a major concern to help meet global challenges. It is therefore essential to propose more sustainable compositions that can thus meet these environmental challenges. Summary of the invention

[0015] (d) at least one C6-C3o fatty alcohol, liquid at room temperature.

[0016] Against all expectations, the inventors have thus found that a composition according to the invention has a satisfactory appearance on the skin after application, in particular without the formation of white traces on the skin, while exhibiting rapid volatility at the time of application followed by the formation of a deposit after drying, providing a satisfactory sensation of comfort and perception of powderiness.

[0202] According to a particular embodiment, a composition according to the invention comprises less than 1.0% by weight, in particular less than 0.5% by weight of silicone surfactant(s) relative to the total weight of the composition, more particularly free of silicone surfactant(s).

[0203] Semi-crystalline polymer(s) containing at least one alkyl acrylate chain

[0204] According to a particular embodiment, the composition according to the invention may comprise at least one semi-crystalline polymer containing at least one alkyl acrylate chain.

[0205] For the purposes of the invention, the term "semi-crystalline polymer" means polymers comprising a crystallizable part, pendant chain or sequence in the skeleton, and an amorphous part in the skeleton, and having a first-order reversible phase change temperature, in particular melting (solid-liquid transition).

[0206] When the crystallizable part is a sequence of the polymer skeleton, this crystallizable sequence is of a chemical nature different from that of the amorphous sequences; the semi-crystalline polymer is in this case a sequenced polymer for example of the diblock, triblock or multiblock type, comprising at least one crystallizable sequence and at least one amorphous sequence.

[0207] By “sequence” we generally mean at least 5 identical repeating units. The crystallizable sequence(s) are then of a different chemical nature from the 5 amorphous sequence(s).

[0208] In particular, the semi-crystalline polymer containing at least one alkyl acrylate chain has an average molecular weight (Mn) greater than or equal to approximately 2000 g / mol, preferably approximately 2000 to 800,000 g / mol, preferably approximately 3000 to 500,000 g / mol, preferably approximately 4000 to 150,000 g / mol, and preferably approximately 4000 to 99,000 g / mol.

[0209] Apart from the crystallizable chains or sequences, the polymer sequences are amorphous.

[0210] By "crystallizable chain or sequence" is meant, within the meaning of the invention, a chain or sequence which, if it were alone, would pass from the amorphous state to the crystalline state, reversibly, depending on whether it is above or below the melting temperature. A chain within the meaning of the invention is a group of atoms, pendant or lateral to the polymer skeleton. A sequence is a group of atoms belonging to the skeleton, a group constituting one of the repeating units of the polymer. Advantageously, the “crystallizable pendant chain” can be a chain comprising at least 6 carbon atoms.

[0211] Preferably, the polymeric backbone of the semi-crystalline polymers is soluble in the oil phase.

[0212] Thus, the semi-crystalline polymer containing at least one alkyl acrylate chain which can be used in a composition according to the invention is generally introduced into the oily phase of the composition.

[0213] Preferably, the crystallizable sequences or chains of the semi-crystalline polymers containing at least one alkyl acrylate chain represent at least approximately 30% by weight and preferably at least approximately 40% by weight relative to the total weight of each polymer.

[0214] In particular, the semi-crystalline polymers with crystallizable sequences that can be used in a composition according to the invention are block or multi-block polymers. They can be obtained by polymerization of monomers with reactive (or ethylenic) double bonds or by polycondensation. When the polymers of the invention are polymers with crystallizable side chains, they are advantageously in random or statistical form.

[0215] For example, the semi-crystalline polymers that can be used in a composition according to the invention are of synthetic origin. Furthermore, they do not comprise a polysaccharide backbone.

[0216] In particular, semi-crystalline polymers may or may not be partially crosslinked. This may then involve chemical crosslinking, by reaction with a multifunctional monomer during polymerization. It may also involve physical crosslinking which may then be due either to the establishment of hydrogen or dipolar bonds between groups carried by the polymer such as dipolar interactions between carboxylate ionomers, these interactions being in small quantity and carried by the polymer skeleton; or to a phase separation between the crystallizable sequences and the amorphous sequences, carried by the polymer.

[0217] Preferably, the semi-crystalline polymers containing at least one alkyl acrylate chain are non-crosslinked.

[0218] As an example of semi-crystalline polymers containing at least one alkyl acrylate chain, mention may be made of those resulting from the polymerization of one or more saturated alkyl (meth)acrylates.

[0219] Preferably, the semi-crystalline polymers with a crystallizable side chain are homopolymers of alkyl(meth)acrylate, or copolymers of these monomers with a hydrophilic monomer.

[0220] According to a particular embodiment, the semi-crystalline polymer containing at least one alkyl acrylate chain is derived from a monomer with a crystallizable chain chosen from saturated alkyl (meth)acrylates, and even more particularly poly(stearyl acrylate) or poly(behenyl acrylate).

[0221] According to another particular embodiment of the invention, the semi-crystalline polymer containing at least one alkyl acrylate chain is chosen from copolymers resulting from the polymerization of at least one monomer with a crystallizable chain chosen from saturated alkyl (meth)acrylates.

[0222] Preferably, the semi-crystalline polymer containing at least one alkyl acrylate chain is chosen from homopolymers obtained by polymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates and from copolymers obtained by copolymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates, with a hydrophilic monomer, preferably N-vinylpyrrolidone or a hydroxyethyl (meth)acrylate, and mixtures thereof, even more preferably a hydroxyethyl (meth)acrylate, and mixtures thereof.

[0223] As a particular example of a semi-crystalline polymer, mention may be made of homopolymers obtained by polymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates, preferably from stearyl acrylates and behenyl acrylates, in particular polymers having the INCI name POLY C10-30 ALKYL ACRYLATE such as the product TEGO® SP 13-1 or TEGO® SP 13-1 MB (formerly Intelimer® IPA 13-1) which is a stearyl polyacrylate marketed by the company EVONIK (AIR PRODUCTS), or the product TEGO® SP 13-6 (formerly Intelimer® IPA 13-6) which is a behenyl polymer (behenyl polyacrylate) marketed by the company EVONIK MATERIALS NE-THERLANDS BV

[0224] As a particular example of another semi-crystalline polymer, mention may also be made of the copolymers obtained by copolymerization of a monomer chosen from alkyl acrylates and alkyl methacrylates, with a hydrophilic monomer, preferably a hydroxyethyl (meth)acrylate, in particular the copolymers described in applications FR 3 073 405 and FR 3 073 406, and preferably the copolymers obtained by copolymerization of at least one monomer chosen from alkyl acrylates, preferably from behenyl acrylates, stearyl acrylates, and mixtures thereof, with a hydrophilic monomer such as hydroxyethyl (meth)acrylate and N-vinylpyrrolidone and preferably hydroxyethyl acrylate.

[0225] Preferably, the semi-crystalline polymer containing at least one alkyl acrylate chain is a behenyl acrylate / 2-hydroxyethyl acrylate copolymer, a stearyl acrylate / 2-hydroxyethyl acrylate copolymer and / or a mixture thereof, and in particular the polymer with the INCI name: Poly C12-22 Alkyl Acrylate / Hydroxyethylacrylate Copolymer, notably marketed under the name Tego® SP Senstar by the EVONIK Company.
