Patent ID: 8632761

Claim:
A hair cosmetic composition comprising a surfactant and a cationized hydroxypropyl cellulose, wherein the cationized hydroxypropyl cellulose has a main chain of an anhydroglucose represented by general formula (1) and has a cationized ethyleneoxy group substitution degree of from 0.01 to 2.5 and a propyleneoxy group substitution degree of from 0.1 to 2.8, wherein R 1 , R 2 and R 3 are each independently a substituent group represented by general formula (2) comprising a cationized ethyleneoxy group and a propyleneoxy group; and n represents an average polymerization degree of the anhydroglucose and is a number of from 50 to 5000, wherein one of Y 1 and Y 2 is a hydrogen atom and the other of Y 1 and Y 2 is a cationic group represented by general formula (3); PO is a propyleneoxy group; and p represents a number of cationized ethyleneoxy groups (—CH(Y 1 )—CH(Y 2 )—O—) present in the general formula (2) and q represents a number of propyleneoxy groups (—PO—) present in the general formula (2), and p and q are respectively 0 or a positive number with the proviso that when neither p nor q is 0, the order of addition of the cationized ethyleneoxy group and the propyleneoxy group is not limited, and when neither p nor q is 0 and at least one of p and q are 2 or more, the cationized ethyleneoxy group and the propyleneoxy group may be added by a block bond or a random bond, wherein R 4 , R 5 and R 6 are each independently a linear or branched alkyl group having 1 to 3 carbon atoms; and X − is an anionic group.
