(57) Abstract: A glyceryl ether group in which at least two hydrogen atoms of a hydroxyl group of a polysaccharide or a derivative thereof have a linear or branched alkyl and / or alkenyl group having 8 to 40 carbon atoms ( 1) and a polysaccharide derivative or a salt thereof each substituted with a carboxymethyl group (2), the substitution degree of the glyceryl ether group (1) is 0.01 to 1.0 per constituent monosaccharide residue, and the carboxymethyl group (2) A degree of substitution of 0.01 to 2.0 per constituent monosaccharide residue, and a content of glyceryl ether group (1) in the polysaccharide derivative of 3.0 to 50% by weight, or a polysaccharide salt thereof, Manufacturing method and cosmetics containing the same. [Effect] It gives a highly transparent aqueous solution, shows excellent thickening effect even when added in a small amount, has little change in viscosity due to coexistence of salts and temperature, and has excellent emulsion stability, and is suitable for cosmetics and toiletry products. It is useful as a thickener and a gelling agent. |
