Description

[0001]Description Title: Cosmetic composition of the oil-in-water emulsion type, having a powdery perception Technical field The present invention relates to the field of cosmetic care and / or makeup compositions, notably in the form of oil-in-water emulsions, which give beneficial sensory properties during the application thereof and drying thereof on a keratin material. The term “keratin material” notably means the skin, the scalp, keratin fibres such as the eyelashes, the eyebrows, head hair, bodily hair, the nails, mucous membranes such as the lips, and more particularly the skin (body, face, neck, neckline, area around the eyes, eyelids). Prior art The presentation forms conventionally selected to afford a powdery feel are solid compositions including pulverulent materials, such as loose or pressed powders, the latter also being referred to as compacts. These presentation forms are particularly appreciated by users with regard to their lightness, softness, tack-free aspect or non-greasy feel. However, this type of composition having a powdery feel also exists in the form of a direct emulsion, i.e. an oily phase dispersed in an aqueous phase. The advantage of these compositions is that they give a similar sensory impression, or even a more suitable sensory impression for caring for the skin, and above all give a perception of freshness and comfort on application. They are also ideal for rapid evaporation of the liquid medium that carries the pulverulent substances. On the other hand, regarding these direct emulsion-type compositions, there is a need to maintain their stability, notably by limiting the phenomenon of phase separation after manufacture, when particulate materials such as pulverulent substances are incorporated therein at high filler contents. The particulate materials of these compositions generally include materials such as hydrophobic silicas and / or particles of the lauroyl lysine type, which are lipophilic in 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 is still not optimal. Moreover, presentation forms incorporating these materials do not give users an immediate marked, soft and smooth powdery perception, notably during drying thereof and / or after drying on the skin. And yet, this is precisely one expectation users have. Moreover, in the case of these direct emulsion-type compositions, there is a need to improve their longevity on the skin after application, notably by limiting their transfer to fabrics, this phenomenon being liable to be exacerbated when pulverulent materials are incorporated in significant amounts. Thus, one aim of the present invention is to develop a presentation form which is able to give users a virtually immediate powdery perception upon application. The invention is also directed towards proposing a composition which gives users feelings of lightness, softness and a tack-free aspect or non-greasy feel. It is also directed towards proposing a composition whose transfer after application to the skin is significantly limited, notably with regard to fabrics which may come into contact therewith. Finally, the invention is also directed towards proposing a presentation formulation with a better carbon footprint, notably by promoting the use of starting materials that are renewable and / or that have a good natural origin index and / or are of natural origin, and / or which are abundant. Specifically, formulating environmentally-friendly cosmetic products, i.e. products whose design and development take environmental issues into account, is becoming a major concern for contributing towards meeting global challenges. It thus proves essential to propose more sustainable compositions, thereby enabling these environmental challenges to be met. Summary of the invention Thus, according to one aspect thereof, the present invention relates to a composition, preferably a cosmetic composition, in the form of an oil-in-water emulsion, comprising: (a) at least one hydrophobic silica; (b) at least one semi-crystalline polymer containing at least one alkyl acrylate chain; and (c) at least one alkane oil with a molecular weight of less than or equal to 200 g / mol. Contrary to all expectation, the inventors have thus found that a composition according to the invention achieves limited transfer after application to the skin, notably low transfer onto a fabric, for example a dark fabric, while at the same time retaining the other desired properties, such as rapid volatility at the time of application followed by the formation of a deposit after drying, affording a satisfactory sensation of comfort and a satisfactory powdery perception. According to a particular embodiment, a composition according to the invention comprises: - at least 7% by weight of hydrophilic silica(s) (a), relative to the total weight of the composition; - from 5% to 35% by weight of alkane oil(s) (c) relative to the total weight of the composition, including at least a mixture of C9-C12 alkane oils; and - from 0.01% to 15% by weight of semi-crystalline polymer(s) (b) relative to the total weight of the composition, including at least the polymer whose INCI name is Poly C10-30 Alkyl Acrylate. More particularly, a composition according to the invention may comprise: - from 7% to 35% by weight of hydrophilic silica(s) (a), relative to the total weight of the composition; - from 5% to 35% by weight of alkane oil(s) (c) relative to the total weight of the composition, including at least a mixture of C9-C12alkane oils; and - from 0.01% to 15% by weight of semi-crystalline polymer(s) (b) relative to the total weight of the composition, including at least the polymer whose INCI name is Poly C10-30 Alkyl Acrylate. Another subject of the present invention is a process for the cosmetic treatment of a keratin material, in which a composition as defined previously is applied to the keratin material. A subject of the present invention is also the use of a composition as defined previously in the cosmetics field, in particular for caring for, protecting and / or making up bodily or facial skin. Other characteristics, aspects and advantages of the invention will become apparent on reading the detailed description that follows. In the text hereinbelow, the expression “at least one” is equivalent to “one or more” and, unless otherwise indicated, the limits of a range of values are included in that range. Detailed description The composition according to the invention is cosmetic and / or dermatological, and is preferably cosmetic. The term “cosmetic” means a composition that is compatible with the skin, mucous membranes and skin appendages. The composition according to the invention is non-therapeutic. The composition according to the invention is generally suitable for topical application to the skin and thus generally comprises a physiologically acceptable medium, i.e. a medium that is compatible with the skin. It is preferably a cosmetically acceptable medium, i.e. a medium which has a pleasant colour, odour and feel and which does not cause any unacceptable discomfort, i.e. stinging, tautness or redness, liable to discourage the user from applying this composition. For the purposes of the invention, the term “limiting the transfer” means significantly reducing or even preventing any undesirable deposition of pulverulent materials forming said composition on substrates with which it is brought into contact, such as fabrics and notably clothing, in particular dark or even black clothing. In other words, limiting such deposits corresponds to an improvement in the transfer-resistance properties of a composition. According to a particular embodiment, the composition according to the invention comprises less than 1.0% by weight, in particular less than 0.5% by weight, of silicone compound(s), relative to the total weight of the composition, and more particularly does not contain silicone compound(s). For the purposes of the present invention, the term “silicone compound” means a compound belonging to the siloxane or polysiloxane (silicone) family, which are known in the cosmetics field, of formula R2SiO or [SiOR2]n, in which R is an organic group, for example an alkyl. Hydrophilic silica (a) The composition according to the invention comprises a hydrophilic silica (a). According to a particular embodiment, the composition according to the invention comprises an amorphous hydrophilic silica (a). An amorphous silica can be natural or synthetic. For example, a synthetic amorphous silica is chosen from microamorphous silicas and mixtures thereof, in particular silica gels, colloidal silicas, amorphous precipitated silicas, fumed silicas and mixtures thereof. According to a particular embodiment, the composition according to the invention comprises a hydrophilic silica (a) chosen from silicas with a mean particle diameter ranging from 1 µm to 30 µm, in particular from 1 µm to 25 µm, and more particularly from 1 µm to 20 µm. Such a mean particle diameter can be characterized, for example, using an apparatus operating under the Coulter principle, and notably the Multisizer™ apparatus sold by the company Beckman Coulter. As hydrophilic silica (a), mention may be made of: the compound having the INCI name Silica, sold under the name Solesphere™ H51 by the company AGC Chemicals Americas, or Sunsphere®H51 sold by the company AGC SI TECH. According to one embodiment, the composition according to the invention comprises at least 7% by weight, in particular at least 10% by weight, more particularly at least 12% by weight, and even more particularly 14% by weight, of hydrophilic silica(s) (a), relative to the total weight of the composition. According to another embodiment, the composition comprises from 7% to 35% by weight, in particular from 7% to 30% by weight, and more particularly from 10% to 25% by weight, of hydrophilic silica(s), relative to the total weight of the composition. Semi- A composition according to the invention comprises at least one semi-crystalline polymer (b) containing at least one alkyl acrylate chain. For the purposes of the invention, the term “semi-crystalline polymer” means polymers including a crystallizable portion, pendent chain or block in the backbone, and an amorphous portion in the backbone, and having a reversible first-order phase transition temperature, in particular melting point (solid-liquid transition). When the crystallizable portion is a block of the polymer backbone, this crystallizable block is of different chemical nature from that of the amorphous blocks; the semi-crystalline polymer (b) is, in this case, a block polymer, for example of the diblock, triblock or multiblock type, including at least one crystallizable block and at least one amorphous block. The term “block” generally means at least five identical repeating units. The crystallizable block(s) are then of different chemical nature from the 5 amorphous block(s). In particular, the semi-crystalline polymer (b) containing at least one alkyl acrylate chain has an average molecular mass (Mn) of greater than or equal to about 2000 g / mol, preferably from about 2000 to 800000 g / mol, preferably from about 3000 to 500000 g / mol, preferably from about 4000 to 150000 g / mol, and preferably from about 4000 to 99000 g / mol. Aside from the crystallizable chains or blocks, the blocks of the polymers are amorphous. For the purposes of the invention, the term “crystallizable chain or block” is understood to mean a chain or block which, if it were alone, would change from the amorphous state to the crystalline state reversibly, depending on whether the temperature is above or below the melting point. For the purposes of the invention, a chain is a group of atoms, which is pendent or lateral relative to the polymer backbone. A block is a group of atoms belonging to the backbone, this group constituting one of the repeating units of the polymer. Advantageously, the “pendent crystallizable chain” may be a chain including at least 6 carbon atoms. Preferably, the polymer backbone of the semi-crystalline polymers is soluble in the oily phase. Thus, the semi-crystalline polymer (b) containing at least one alkyl acrylate chain that may be used in a composition according to the invention is generally introduced into the oily phase of the composition. Preferably, the crystallizable blocks or chains of the semi-crystalline polymers containing at least one alkyl acrylate chain represent at least about 30% by weight and preferably at least about 40% by weight relative to the total weight of each polymer. In particular, the semi-crystalline polymers with crystallizable blocks that may be used in a composition according to the invention are block or multiblock polymers. They may be obtained by polymerizing monomers bearing reactive (or ethylenic) double bonds or by polycondensation. When the polymers of the invention are polymers bearing crystallizable side chains, these polymers are advantageously in random or statistical form. For example, the semi-crystalline polymers that may be used in a composition according to the invention are of synthetic origin. Moreover, they do not include a polysaccharide backbone. In particular, the semi-crystalline polymers may or may not be partly crosslinked. It may then be a case of chemical crosslinking, by reaction with a multifunctional monomer during the polymerization. It may also be a case of physical crosslinking, which may then be due either to the establishment of bonds of hydrogen or dipolar type between groups borne by the polymer, such as dipolar interactions between carboxylate ionomers, these interactions being in small amount and borne by the polymer backbone; or due to a phase separation between the crystallizable blocks and the amorphous blocks borne by the polymer. Preferably, the semi-crystalline polymers containing at least one alkyl acrylate chain are non- crosslinked. As examples 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. Preferably, the semi-crystalline polymers bearing a crystallizable side chain are alkyl (meth)acrylate homopolymers, or copolymers of these monomers with a hydrophilic monomer. According to a particular embodiment, the semi-crystalline polymer (b) containing at least one alkyl acrylate chain is derived from a monomer bearing a crystallizable chain chosen from saturated alkyl (meth)acrylates and even more particularly poly(stearyl acrylate)s or poly(behenyl acrylate)s.

Protocol for evaluation of the sensory impression The technical effects relating to the sensory impression after application of a composition, notably with regard to the feeling of comfort and the powdery effect, were demonstrated via the following protocol, performed by five assessors: - application of a defined amount of a composition, corresponding to 0.2 g, on the back of the hand; - spreading of the composition circularly and evenly over the back of the hand, completing 15 circular motions in 15 seconds; and - evaluation of the comfort and the powdery effect 2 minutes 30 seconds after applying the composition. Protocol for evaluating the transfer onto a fabric This technical effect was evaluated using a Supplale support (supplied by Soudotique) which is a flexible black fabric made of artificial leather bonded to a collagen film, and which has a roughness that allows it to simulate that of the skin. This Supplale support has two sides: a “skin” side and a “fabric” side mimicking black clothing. The evaluation protocol is as follows: - an amount of composition is applied by finger to the “skin” side of a first Supplale support until this deposited amount of composition no longer slides and catches; - the first Supplale support including the spread composition is left to dry for one hour, - the “fabric” side of a second Supplale support is rubbed against the composition deposit; and - the appearance of white traces due to filler transferring is visually evaluated on this “fabric” side of the second Supplale support, - the level of transfer is also evaluated by visual assessment of the cream residue on the “skin” side of the first Supplale support. With regard to these two observations: - a score of “0” is awarded when no transfer is observed, - a score of “1” is awarded for slight transferring, notably when the white traces found on the second support are very faint; and - a score of “2” is awarded for significant transferring, notably when the white traces found on the second support are very visible. Preparation and evaluation of compositions according to the invention and comparative compositions A composition according to the invention (I1) and a composition outside the invention (C1), free of semi-crystalline polymer (b), were prepared according to the preparation protocol described hereinbelow, with the nature of the ingredients and their respective amounts reported in Table 1. The contents are expressed as weight percentages relative to the total weight of the composition. Process for preparing the compositions The components of phase A are mixed in a Rayneri mixer equipped with a mobile rotor / stator and a deflocculator, followed by the addition of boiling water to the mixture obtained. The components of phase B1 are heated to 75-85°C (melting of the fatty substances). The mixture obtained is added to phase A, with stirring by rotor / stator (1300 rpm), without heating. The mixture obtained is cooled to a temperature below 55°C, followed by the addition of phase B2, with stirring by rotor / stator. The emulsion obtained is examined under the microscope after 10 minutes. The components of phase C are added to the emulsion, with stirring by the deflocculator. The emulsion obtained is once again examined under the microscope after 10-15 minutes. The components of phase D are added portionwise to the emulsion, cooled with an ice bath, and stirring with the deflocculator. The phase E is added to the mixture, stirring with the deflocculator so that the temperature remains below 30°C.

It is observed that composition I1 according to the invention is satisfactory in terms of the comfort and the powdery effect. The transfer was also characterized (Table 1) after application, for composition I1 according to the invention and composition C1 outside the invention, following the evaluation protocol described above. It is found that composition I1 according to the invention leads to a low amount of white traces being transferred onto the fabric, in contrast to the comparative composition C1. Composition I1 according to the invention thus has significantly improved transfer- resistance properties relative to the comparative composition C1.
