Definitions

• the subject of the invention is a cosmetic composition
• a cosmetic composition comprising, in a cosmetically acceptable medium, at least one polymer (A) with particular characteristics. It also relates to a method of shaping or maintaining hair using this composition, as well as its use for the formulation of styling products such as hairsprays, sprays or mousses, with a view to obtaining the maintaining or shaping the hairstyle.
• compositions for spraying in an aerosol or in a pump bottle such as lacquers, sprays or foams, essentially consisting of a more often alcoholic or hydroalcoholic " and of a film-forming polymer soluble in water or in alcohol, in mixture with various cosmetic adjuvants.
• these hair formulations such as mousses, gels and especially sprays and aerosol lacquers intended to maintain the shape of the hairstyle do not yet allow the hairstyle to resist satisfactorily the various natural movements of life such as walking, head movements or gusts of wind.
• the polymers used for the formulation of these hair products are anionic, amphoteric or nonionic film-forming polymers, which lead to the formation of films having a more or less hard and brittle nature.
• the percentage of elongation at break measured on the film is low, that is to say generally less than 2% and the holding of the hairstyle is not ensured over time.
• these polymers have already been mixed with plasticizers and obtained more flexible and non-friable coatings.
• these films are deformable and plastic, that is to say that after deformation, they recover very little of their initial shape. If the holding of the hairstyle is improved, it is not yet satisfactory since the shape of the hairstyle changes over time.
• compositions comprising a combination of film-forming polymers, such as for example a polyvinylcaprolactam polymer and an acrylic polymer.
• film-forming polymers such as for example a polyvinylcaprolactam polymer and an acrylic polymer.
• these compositions are not yet entirely satisfactory, insofar as the hair loses some of its natural cosmetic properties.
• the subject of the invention is a cosmetic composition
• a cosmetic composition comprising, in a cosmetically acceptable medium, at least one film-forming polymer (A) chosen such that the material obtained by drying this polymer in an aqueous or alcoholic medium, at room temperature and at a relative humidity of 50%, has a mechanical profile defined by at least:
