Copolymers of the formula: <IMAGE> wherein the bonds between the glucoside units are beta (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. |
