摘要
A polymer combination for formulating hair styling compositions consists of a first polymer (A) which gives films having specified mechanical properties, and a second, different, polymer (B) selected from 13 given polymers. Hair styling composition comprising, in a cosmetically acceptable medium, (1) at least one polymer (A) selected such that a film obtained by drying a mixture of the polymer (A) with ethanol or water at ambient temperature and a relative humidity of 50 %, has a mechanical profile defined by at least (i) an elongation at rupture greater than or equal to 300 %; (ii) 300 second recovery (R300) greater than or equal to 45 % and (iii) if the 300 second recovery = 45-60 % then the elongation is less than 1300 %; and (2) at least one nonionic film-forming polymer (B), different to the polymer (A), and selected from polyalkyloxazolines; homopolymers of vinyl acetate; copolymers of vinyl acetate and acrylic esters; copolymers of vinyl acetate and ethylene; copolymers of vinyl acetate and maleic esters; copolymers of polyethylene and maleic anhydride; homopolymers of alkyl (meth)acrylates; copolymers of acrylic esters such as copolymers of alkyl acrylates and alkyl methacrylates; copolymers of acrylonitrile and a nonionic monomer selected from butadiene and alkyl (meth)acrylates; copolymers of alkyl acrylates and urethane; guar gums; polymers derived from hydroxystyrene; and homo- and copolymers of vinyl lactams.
