Description

The present invention relates to a cosmetic composition comprising, in a cosmetically acceptable medium, one or more vinylformamide / vinylformamine copolymers and one or more cationic polymers. The present invention also relates to a process for the cosmetic treatment of hair, in particular a process for fixing and / or shaping the hair using the aforementioned composition. The present invention finally relates to a use of this composition for the cosmetic hair treatment, and in particular for styling the hair, that is to say shaping and / or fixing the hairstyle. Hair styling products are usually used to build, structure the hairstyle and give it a lasting hold. They are usually in the form of lotions, gels, mousses, creams, sprays, etc. The corresponding compositions generally comprise one or more film-forming polymers or fixing polymers, in a cosmetically acceptable medium. These polymers allow the formation of a sheathing film on the hair, thus ensuring the maintenance of the hairstyle. However, the fixing polymer films thus formed have the disadvantage of being relatively friable, which limits in time the holding of the hairstyle, and causes the formation on the hair of unsightly residues. Thus, conventional styling products lead to a fixation of the hairstyle and styling effects that gradually fade over time. In particular, when the product is applied in the morning, the styling effects fade as the day progresses. The next day, styling effects are weak or non-existent.

To remedy this problem, it is known to incorporate in the styling products polymers with a very high fixing power, and / or to increase the concentration of fixing polymer. However, the use of such extremely fixative products causes a number of disadvantages. In particular these products lead to a dry and rough feel of the hair and are difficult to remove with shampoo. There is therefore a need for hair compositions that make it possible to obtain a lasting fixation of the hairstyle, with styling effects that persist throughout the day or even several days, while eliminating easily with shampooing and providing a pleasant cosmetic feel, and in particular a smooth touch. International Patent Application WO 96/03969 generally discloses cosmetic compositions for fixing and / or conditioning hair, which comprise a homopolymer of vinylformamide or a copolymer of vinylformamide and one or more other vinyl monomers in combination with at least one ingredient selected from conditioning agents, emulsifying agents, surfactants, viscosity modifiers, gelling agents, opacifying agents, stabilizing agents, preservatives, sequestering agents, chelating agents, pearlescent agents, clarifying agents, perfumes, dyes, propellants, organic solvents and water.

Furthermore, US Pat. No. 4,421,602 describes vinylformamide / vinylformamine copolymers, their preparation and their use in the paper industry to improve retention, flow rate, and flocculation. The Applicant has now discovered that, surprisingly, the combination of a vinylformamide / vinylformamine copolymer with a cationic polymer in a non-washing cosmetic composition (that is to say with a low content of anionic and nonionic surfactants, or even free of such surfactants) allowed to obtain a cosmetic hair composition providing improved styling properties. In particular, such an association makes it possible to obtain styling products that provide a lasting fixation of the hairstyle, while easily eliminating washing and providing a pleasant cosmetic feel to the hair.

The present invention thus makes it possible to prepare hair styling products that provide very high levels of fixation, a very long hold of the hairstyle over time, and good resistance to mechanical stresses. After shampooing, the touch of the hair is particularly soft, and the hair is loosened.

The subject of the present invention is therefore a cosmetic composition comprising, in a cosmetically acceptable medium: one or more vinylformamide / vinylformamine copolymers comprising: from 10 to 95 mol% of units of the following formula A: CH 2 CH 2 NH 2 (A) and from 90 to 5 mol% of units of the following formula: ## STR2 ## and one or more cationic polymers other than the vinylformamide / vinylformamine copolymers, this composition containing less than 5% by weight in total of anionic surfactants. and nonionic surfactants.
