| abstract |
Copolymers of formula (I) wherein the bonds between the glucoside units are β (1←4), the degree of polymerization referred to a single glucoside unit varies from about 50 to 50,000, R is a free or esterified carboxy group and S is an amino or acylamino group. The part designated by x may vary between about 5 % and 100 % and that designated by y may vary between about 95 % and 0 %. At least a part of the R groups are esterified carboxy groups, and at least a part of the S groups are acylamino groups. Salts of these copolymers are also disclosed. The products of the invention are particularly useful in the cosmetic field. |
