| abstract |
The invention relates to cationic or amphoteric polyurethanes bearing at least one tertiary or quaternary amine function and having a self-adhesion value—expressed by the maximum tensile force (F max (in N)) recorded during the detachment by traction of two circular surfaces of 0.95 cm 2 , coated with the said polyurethanes—of greater than or equal to 11 N. The invention also relates to the use of these self-adhesive cationic polyurethanes, in cosmetics and in particular in styling compositions. |
