Description

Title of the invention: Composition comprising at least one (CrC6)alkyl acrylic acid polymer, hyaluronic acid and a hydrophilic gelling agent

[0001] The present invention relates to a composition, particularly a cosmetic one, comprising at least one polymer derived from (C1-C6)alkyl acrylic acid or one of its salts, less than 0.15% by weight relative to the total weight of the hyaluronic acid composition and / or one of its salts, and at least one hydrophilic gelling agent distinct from the polymer derived from (C1-C6)alkyl acrylic acid or one of its salts and from the hyaluronic acid and / or its salts. It also relates to a cosmetic treatment method for skincare, particularly for oily skin, comprising the application of a cosmetic composition according to the invention.

[0002] Sebum normally acts as a moisturizing agent for the epidermis. It is the natural product of the sebaceous gland, which is an extension of the pilosebaceous unit. It is essentially a more or less complex mixture of lipids. Typically, the sebaceous gland produces squalene, triglycerides, aliphatic waxes, cholesterol waxes, and possibly free cholesterol.

[0003] Hyperseborrheic oily skin is characterized by excessive secretion and excretion of sebum. Classically, a sebum level exceeding 200 pg / cm² measured on the forehead is considered characteristic of such oily skin. This type of skin is also often associated with poor desquamation, a shiny complexion, and / or a thick skin texture, i.e., manifestations perceived as skin imperfections or aesthetic disorders.

[0004] Skin shine is generally linked to a significant secretion of sebum, but can also be linked to sweat, result from physical activity or climatic conditions (heat, humidity); it can also be due to the combination of the two phenomena (sebum and sweat).

[0005] In addition to the active ingredients that prevent and / or treat this significant sebum secretion, compositions are sought that have an appearance that is consistent with the purpose for which this composition is used by the consumer.

[0006] Thus, a composition with minimal shine, a granite / sorbet appearance and a gliding effect on application to the skin is highly sought after by users, especially those with combination or oily skin, as it gives a perception of lightness and freshness while ensuring a certain comfort during application.

[0007] There is therefore a need for cosmetic compositions, particularly those adapted to oily or oily-prone skin, that have good sensory properties, namely a minimal shine (i.e. very slightly shiny) and a granite / sorbet appearance while maintaining a smooth effect when applied to the skin.

[0008] The Applicant has now discovered that a composition comprising at least one polymer derived from (Ci-C6)alkyl acrylic acid, hyaluronic acid or one of its salts in a certain content and at least one hydrophilic gelling agent distinct from the polymer derived from (Ci-C6)alkyl acrylic acid and hyaluronic acid, exhibits both minimal shine, a granite / sorbet-like appearance and a good glide effect when applied to the skin.

[0009] Thus, the object of the invention is a composition, in particular a cosmetic one, comprising:

[0010] i) at least one polymer derived from (Ci-C6)alkyl acrylic acid or one of its salts, comprising a repetition of formula units (I):

[0011] [Chem.l]

[0012] formula (I) in which:

[0013] * R1 and R2, whether identical or different, represent a hydrogen atom or a (Ci-C6)alkyl group such as methyl, preferably R1 and R2 represent a hydrogen atom,

[0014] * M+ represents a cationic counterion, preferably an alkali metal, alkaline- earthy or ammonium, more preferably M+ represents an alkali metal such as sodium;

[0015] ii) less than 0.15% by weight relative to the total weight of composition, of hyaluronic acid and / or one of its salts, and

[0016] iii) at least one hydrophilic gelling agent distinct from the polymer derived from (Cl-C6)alkyl acrylic acid or one of its salts and hyaluronic acid and / or its salts.

[0017] Such a composition according to the invention is advantageous in several respects: it gives the user a perception of freshness and lightness upon application due to its minimal shine (i.e. very slightly shiny) and its granite appearance (like finely crushed ice), while maintaining a certain comfort thanks to a gliding effect when applied to the skin.

[0018] For the purposes of this invention, "granite" describes an appearance with a slightly grainy, frosted effect. A granite appearance is synonymous with a frosted texture; a "frosted texture" is understood to be a composition with a sorbet-like appearance that melts on the skin upon application. Such a frosted texture is characterized, in particular, by the presence of agglomerates distributed homogeneously throughout the composition.

[0019] The granite effect and minimal gloss of the composition according to the invention are visual characteristics of the composition, which can in particular be evaluated in its container such as a jar, and are particularly interesting in the context of compositions intended for the treatment of oily skin, because they give the consumer the perception of a light and fresh texture.

[0020] The gliding effect of the composition according to the invention can be evaluated by determining the number of turns that can be made on the skin during a defined time, for example the number of turns for 15 seconds after application of the composition to the skin.

[0021] Advantageously, the composition according to the invention has a viscosity of less than 40 Pa.s, preferably a viscosity of 20 to 40 Pa.s, more preferably of 25 to 40 Pa.s, even better of 30 to 40 Pa.s.

[0022] The viscosity measurement is carried out at 30°C, using an Ametek Brookfield HADV2T viscometer equipped with a No. 6 wheel such as the reference HA-6, the measurement being carried out after 1 minute of rotation of the wheel within the composition (time at the end of which a stabilization of the viscosity and the rotation speed of the wheel is observed), at a speed of 10 revolutions / min (rpm).

[0023] The invention also relates to a cosmetic treatment method for skin care, in particular oily skin, comprising the application of a cosmetic composition according to the invention.

[0024] For the purposes of the present invention, and unless otherwise indicated:

[0025] By "polymer(s)" we mean one or more homopolymer(s) (i.e. resulting from the polymerization of identical synthons), one or more copolymer(s) (i.e. resulting from the polymerization of different synthons), or their mixtures i.e. homopolymers and copolymers.

[0026] By "(C j -C 6 )alkyl group", we mean a saturated hydrocarbon radical, linear or branched, in Ci-C6, preferably in Ci-C4.

[0027] By "cationic counter-ion" is meant a cation or a cationic group from an organic or mineral base salt counterbalancing the anionic charge of the ingredients of formula (!') or (II'); more particularly the cationic counter-ion is chosen from alkali metals such as sodium, potassium, preferably Na+; alkaline earth metals such as calcium; ammonium (R)4N+ with R, identical or different, represents a hydrogen atom or a (Ci-C6)alkyl group optionally substituted by one or more hydroxy groups, preferably R represents a hydrogen atom or a (Ci-C4)alkyl group such as methyl.

[0091] These are water-soluble polymers, dispersible in water or inflatable in water. These polymers used according to the invention are homo- or copolymers that can be obtained from at least one monomer with ethylenic unsaturation and a sulfonic group, which may be in free form or partially or totally neutralized.

[0092] Preferably, the sulfonic group polymers used according to the invention can be partially or completely neutralized by a mineral base (such as sodium hydroxide, potassium hydroxide, or aqueous ammonia) or an organic base such as mono-, di-, or triethanolamine, aminomethylpropanediol, N-methylglucamine, or basic amino acids such as arginine or lysine, or mixtures of these compounds. They are generally neutralized. In the present invention, the term "neutralized" is intended to designate polymers that have been completely or almost completely neutralized, that is, neutralized to at least 90%.
