Abstract
Provided is a skin cleansing composition comprising the following components (A), (B), and (C): (A) from 0.5 to 40 mass % of an ether oil in a liquid state at 25° C., (B) from 0.01 to 5 mass % of a nonionic water-soluble polymer comprising cellulose as a constitutional unit selected from the group consisting of methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and hydroxypropylmethylcellulose, and (C) water, and 1 mass % or less of a nonionic surfactant, wherein the mass ratio of the component (B) to the component (A), (B)/(A) is from 0.001 to 5.
