Title:
NEW POLYSACCHARIDE DERIVATIVE, ITS PRODUCTION AND COSMETIC CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP3165377
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a new polysaccharide derivative that provides a highly transparent aqueous solution, develops an excellent thickening effect with little viscosity change, and excellent emulsification stability by addition of a small quantity of the derivative, and is useful as a thickening agent and gelling agent for toiletry products.
SOLUTION: This new polysaccharide derivative comprises a polysaccharide or its derivative a part or all of hydrogen atoms of hydroxide groups of which is replaced with either group (A): a 10-40C alkyl, alkenyl or acyl group in which OH may be replaced, and COO or OCO may be inserted therein, or (B): a 1-5C sulfoalkyl group in which OH may be replaced, or a salt of them, and respective average degrees of substitution per constitutional monosaccharide moiety are 0.001-1.0 for group (A) and 0.01-2.0 for group (B).
