  • Polymer for treating hair
    Patent number: 11471706
    Abstract: The present invention relates to a polymer comprising repeating units derived from at least one first monomer (monomer A) which is a molecule comprising a thiolactone ring and an ethylenically unsaturated, polymerizable double bond, and at least one second monomer (monomer B) which is N-vinyl pyrrolidone. Furthermore the present invention relates to a modified polymer, the structure of which is identical to the structure of the said polymer apart from the only difference, which is that all or at least some of the thiolactone moieties of the said polymer are modified by opening the thiolactone ring with a substance selected from the group consisting of ammonia, a primary amine, 2-amino-1-ethanol and L-lysine, wherein the N-atom of said substance is binding to the carbonyl group of the opened thiolactone ring. Furthermore, the present invention relates to a process for making the modified polymer and to the use of the polymer or of the modified polymer for treating hair.
    Type: Grant
