Component A: Polyethylene glycol Component B: Ester oil having an IOB value of 0.1 or more and less than 0.6 Component C: Nonionic surfactant having an HLB value of 19.3 or less The skin cleansing composition defines component A. By including it in terms of content, it is excellent in affinity with water, a feeling of use, and washability after use. As used herein, "excellent in affinity with water" means that the skin cleansing composition is easily mixed with water. As used herein, the term "excellent in usability" means that the skin cleansing composition exhibits good elongation when applied to the skin. In the present specification, "excellent in washing off after use" means that the skin cleansing composition adhering to the skin can be easily washed away with water or the like. In addition, component A can also be used for the purpose of adjusting the viscosity of the skin cleansing composition.

Since the skin cleansing composition contains the component A and the component B, the skin cleansing composition can be blended with the stains on the skin, and thus has excellent stain removing power.

When the skin cleansing composition contains the component C, it is possible to reduce the stickiness and oily feeling caused by the oily component after use. That is, after using the skin cleansing composition according to the present invention, a good finish without stickiness can be obtained.

<Ingredient A>
