PROBLEM TO BE SOLVED: To provide a skin cleansing agent composition which materializes fine foam quality with excellent elasticity and skin with a moist feeling and without stiffness after finishing of washing.SOLUTION: The skin cleansing agent composition contains: (A) 1 to 20 mass% of alkyl ether carboxylic acids represented by general formula (1) (in formula, R1 represents a 4-22C alkyl group, and n represents a number from 0 to 20), wherein the average number of carbon atoms in R1 is 10.8 to 12.8, the content of components in which n=0 is 4.3 to 30 mass%, and the total content of components in which n=1 and components in which n=2 is at least 20 mass% and less than 40 mass% (B) 1 to 20 mass% of a straight chain or branched chain 10-22C fatty acids (C) 0.1 to 5 mass% of a cationic polymer (D) a base and (E) water. At least a part of the component (A) and a part of the component (B) are present in the form of salts with the component (D), and a molar ratio of the component (D) relative to the component (A) and the component (B) (component (D))/(component (A)+component (B)) is 0.9 to 1.1.COPYRIGHT: (C)2013,JPO&INPIT【課題】泡質がキメ細かく弾力性に優れ、洗い上がりの肌がしっとりしてつっぱらない皮膚洗浄剤組成物の提供。【解決手段】(A)一般式(1)(式中、R1は炭素数4~22のアルキル基を示し、nは0~20の数を示す)で表されるアルキルエーテルカルボン酸であって、R1の平均炭素数が10.8~12.8であり、n=0の成分を4.3~30質量%含み、n=1の成分とn=2の成分の合計含有量が20質量%以上40質量%未満であるアルキルエーテルカルボン酸1~20質量%、(B)炭素数10~22の直鎖又は分岐の脂肪酸1~20質量%、(C)カチオンポリマー0.1~5質量%、(D)塩基、(E)水を含有し、成分(A)及び(B)は、少なくとも一部が成分(D)と塩で存在し、成分(D)は、成分(A)及び(B)に対するモル比(成分(D)/(成分(A)+成分(B))が0.9~1.1である皮膚洗浄剤組成物。【選択図】なし
