HAIRSTYLING COMPOSITION COMPRISING A POLYMER WITH PARTICULAR CHARACTERISTICS AND AN IONIC FILM FORMING POLYMER

摘要

The invention concerns a hairstyling composition comprising, in a cosmetically acceptable medium: (1) at least a polymer (A) selected such that the film obtained by drying of a mixture of said polymer (A) with ethanol or water, at room temperature and at a relative moisture content of 50 % has a mechanical profile defined by at least: (i) an ultimate elongation rate ( epsilon r) not less than 300 % ; (ii) a creep at 300 seconds (R300) not less than 45 % ; and (iii) when the creep at 300 seconds ranges between 45 and 60 %, the elongation is less than 1300 % ; (2) at least a film forming polymer (B) different from polymer (A) and selected among anionic, cationic or amphoteric film forming polymers. The invention also concerns a hairstyling or hair-fixing method using said composition and its use for formulating hairstyling products such as lacquers, sprays and foams for hairstyling and hair fixing.
