Skin cleanser composition

A skin cleanser composition comprising a cationized hydroxypropyl cellulose (A) and a surfactant (B), wherein the cationized hydroxypropyl cellulose (A) has an anhydroglucose-derived main chain represented by the following general formula (1), and has a degree of substitution with cationized ethyleneoxy group of from 0.01 to 3.0 and a degree of substitution with propyleneoxy group of from 0.01 to 2.9:

• wherein R1, R2 and R3 each independently represent a substituent having a cationized ethyleneoxy group and a propyleneoxy group represented by the following general formula (2);
• n indicates a mean degree of polymerization of anhydroglucose and is a number of from 20 to 5000,
• wherein one of Y1 and Y2 is a hydrogen atom and the other is a cationic group represented by the following general formula (3);
• PO represents a propyleneoxy group;
• p indicates the number of cationized ethyleneoxy groups (—CH(Y1)—CH(Y2)—O—) in the general formula (2) and q indicates the number of propyleneoxy groups (—PO—) therein, each being 0 or a positive integer;
• in case where both of p and q are not 0, the addition sequence of the cationized ethyleneoxy group and the propyleneoxy group is not defined, and in case where p and/or q are/is 2 or more, a binding form may be a block co-polymer or a random co-polymer;
• wherein R4, R5 and R6 each independently represent a linear or branched alkyl group having from 1 to 3 carbon atoms, and X− represents an anionic group.
