摘要

A cosmetic composition comprises in solution in an appropriate vehicle at least one polymer having 50-100% of repeating units of the beta -alanine type having the formula (I) and 0-50% of repeating units of the acrylamide type having the formula (II) wherein R1 represents hydrogen or a member selected from the group consisting of (i) (ii) -CH2OH, (iii) -(CH2)n-CH3 wherein n is 0 or a whole number from 1 to 11, (iv) wherein r' and r'' each independently represent hydrogen or alkyl having 1-3 carbon atoms, (v) -CHOH-COOH, (vi) -CH2-SO3Na, (vii) and (viii) -(CH2-CH2-O)mH wherein m ranges from 1 to 10, and R2 and R3 represent hydrogen or methyl.
