Description

 COMPOSITION COMPRISING A PARTICULAR ACRYLIC COPOLYMER AND ANIONIC FIXING POLYMER COMPRISING AN ACID MONOMER

 CROTONIC

 The present invention relates to a composition for the treatment of keratinous fibers, in particular human keratinous fibers such as the hair, comprising one or more particular acrylic copolymers and one or more fixing polymers. The present invention also relates to a method for shaping and / or maintaining the hairstyle using said composition and the use of said composition for shaping and / or maintaining the hairstyle.

 In the field of styling, in particular among products intended for shaping and / or maintaining the hairstyle, the most popular hair compositions on the cosmetics market are compositions consisting essentially of a solution most often alcoholic or hydroalcoholic and one or more polymers, called fixing polymers, which are generally film-forming polymers. These polymers thus have the function of making welds between the hair so as to be able to structure the hairstyle and bring it a lasting hold.

 However, some fixing polymers cause a hardening of the hair. This inconvenience leads to a fixed hairstyle and a difficult disentangling at the end of the day, the hair having a dry touch.

 To improve the cosmetic feel of the hair, it is known to add silicone or oxyethylenated compounds. However, this type of association tends to decrease the level of fixation of the compositions and to reduce the behavior of the hairstyle.

 JP2007-223943 and JP2007-63186 disclose hair compositions associating a silicone-fixing polymer.

 For example, JP2007-223943 describes hair compositions comprising a film-forming acrylic copolymer, wherein the film-forming acrylic copolymer can be combined with an alkyl acrylate / methacrylic acid / silicone copolymer. The compositions obtained make it possible to obtain good strength properties without adding stiffness or stickiness.

JP2007-63186 also discloses hair compositions comprising a film-forming acrylic copolymer, the film-forming acrylic copolymer being capable of being associated with a methylpolysiloxane or a methylphenylpolysiloxane. The compositions obtained provide fixation and a cosmetic feel, especially softness. Furthermore, JP2007-217314 discloses hair compositions comprising a film-forming acrylic copolymer, the film-forming acrylic copolymer being capable of being associated with an alkyl acrylate copolymer. The compositions obtained make it possible to give a natural rendering without generating stickiness.

 However, the properties obtained in terms of fixation (level, durability), and cosmetics (smooth touch, disentangling) are not optimal.

 There is therefore a real need to find compositions, especially for styling, which allow a good level of fixation and maintenance of the hairstyle, durable, while providing a cosmetic touch to the hair.

 The Applicant has found surprisingly and unexpectedly that the combination of a particular acrylic copolymer and a fixing polymer allowed to obtain a hair not having the above disadvantages.

 Indeed, this combination provides a strong attachment of the hair, lasting on the day, while providing a cosmetic touch to the hair. The surface of the hair is smoother and the hair is held in the desired shape without being fixed or hardened.

 In addition, detangling at the end of the day is easier, the touch is non-sticky and the hair softer, are soft and smooth.

 The subject of the invention is therefore a composition, comprising:

 (i) one or more acrylic copolymers comprising as monomers:

 (a) at least one unsaturated acidic monomer selected from acrylic or methacrylic acids or their salts;
