Title: COSMETIC HAIR COMPOSITION PROVIDING GOOD RESISTANCE PROPERTIES AND COMPRISING POLYURETHANES
Abstract:
The invention concerns a cosmetic composition comprising, in a cosmetically acceptable medium, at least a film-forming polyurethane (A) selected such that the material resulting from drying said polymer in an aqueous or alcoholic medium, at room temperature and at a relative humidity rate of 50 %, has a profile defined by at least: (a) an ultimate elongation (εr) not less than 500 %; (b) an instantaneous recovery (Ri) ranging between 30 and 85 %; (c) a recovery (R300) at 300 seconds ranging between 50 and 100 %; (d) a glass transition temperature less than 45 °C.
