Abstract
Cosmetic or personal care compositions, such as for styling hair, comprise a thermoplastic elastomer which is a block copolymer comprising a core polymer having a backbone comprising at least a proportion of C—C bonds and two or more flanking polymers. Each flanking polymer is covalently bound to an end of the core polymer and the core polymer and/or at least one of the flanking polymers is a copolymer derived from two or more monomers. The compositions comprise a cosmetically acceptable diluent or carrier.

Cosmetic or personal care composition comprising a thermoplastic elastomer which is a block copolymer comprising a core polymer block comprised of monomers selected from acrylate esters, and two or more flanking polymer blocks, each flanking polymer block being covalently bound to an end of the core polymer block, wherein at least one of the polymer blocks is a random copolymer derived from two or more monomers;
- and a cosmetically acceptable diluent or carrier.
A cosmetic method of treating hair which comprises the step of applying to the hair a composition comprising a thermoplastic elastomer which is a block copolymer comprising a core polymer block comprised of monomers selected from acrylate esters;
- and two or more flanking polymers blocks, each flanking polymer block being covalently bound to an end of the core polymer block, wherein at least one of the polymer blocks is a random copolymer derived from two or more monomers;
- and a cosmetically acceptable diluent or carrier.
