Abstract

The present invention relates to a composition for a cleansing agent comprising a component (A) in the form of an ionic surfactant and a component (B) in the form of one or more types of compounds selected from the group consisting of a hydroxystearic acid polymer and an esterification reaction product of a hydroxystearic acid polymer. According to the present invention, a composition for a cleansing agent can be provided that has favorable foaming power and foam quality, is easily rinsed during cleansing, is free of stickiness after cleansing and allows the obtaining of a moist feeling.

First claim

The invention claimed is:

1. A cleansing agent, comprising:
a component (A) in the form of one or more types of surfactants selected from the group consisting of an anionic surfactant and an amphoteric surfactant, a component (B) in the form of a hydroxystearic acid polymer, a component (C) in the form of a dispersion medium, and water, wherein an average number of monomers of the hydroxystearic acid polymer is 4 to 12.

2. The cleansing agent according to claim 1 , wherein an amount of the component (A) is 5 to 60% by weight, relative to a total amount of the cleansing agent.

3. The cleansing agent according to claim 1 , wherein an amount of the component (B) is 0.1 to 15% by weight, relative to the total amount of the cleansing agent.

4. The cleansing agent according to claim 1 , wherein the component (B) comprises polymers of 12-hydroxystearic acid.

5. The cleansing agent according to claim 1 , wherein the component (C) is a polyvalent alcohol.

6. The cleansing agent according to claim 5 , wherein the polyvalent alcohol is one or more polyvalent alcohols selected from the group consisting of propylene glycol, glycerin, diglycerin, 1,3-butylene glycol, isoprene glycol, dipropylene glycol, polyethylene glycol, pentaerythritol, dipentaerythritol, neopentyl glycol, sorbitol, and sorbitan.
