Kind Code:

A1

Abstract:

A polysaccharide derivative having a structure formed by replacing part or all of the hydrogen atoms of the hydroxyl groups in a polysaccharide or a derivative thereof with a group represented by the formula (1) -E?1¿-(OA)¿n?-E?2¿-R (wherein E?1¿ represents a C¿1-6? divalent saturated hydrocarbon group optionally substituted by hydroxy or oxo; n is a number of 8 to 300; nA's are the same or different and each represents a C¿1-6? divalent saturated hydrocarbon group; E?2¿ represents an ether bond or oxycarbonyl; and R represents C¿4-30? alkyl optionally substituted by hydroxy) [the hydrogen atom of the hydroxyl group in the group (A) may be replaced with a group (A)]; a thickener and an emulsifier each comprising the derivative; and an aqueous composition containing the derivative. The polysaccharide derivative has excellent handleability at low temperatures. It is useful in various toiletry as a thickener having sufficient thickening properties at high temperatures or as an emulsifier having excellent emulsifying activity serving as a stabilizer.
