JP6833320B2 - Skin cleanser composition - Google Patents

Description

The present invention relates to a skin cleansing composition, and more specifically, it has excellent foam amount and foam quality, does not have a dry feeling like soap after washing and towel drying, and has a smooth finish, but has a slimy finish during rinsing. It relates to a skin cleansing composition that provides a refreshing and refreshing sensation.

Conventionally, soap has been widely used as a liquid or paste-like skin cleanser such as body soap and face wash from the viewpoint of excellent foam volume and creaminess of foam quality during use. However, in recent years, due to the diversification of consumer needs for skin cleansers, not only the amount of foam at the time of use and the creaminess of the foam quality, but also the foaming easiness and rinsing property, and the texture after washing have been emphasized. Furthermore, the number of consumers with sensitive skin is increasing, and various base surfactants such as blending a mild surfactant for the skin are being sought after.

For example, alkyl sulfates and polyoxyethylene alkyl ether sulfates have a texture after washing that is different from that of soaps, but they always feel slimy during rinsing, and they do not give a refreshing or refreshing feeling.

In addition, N-acylamino acid salt is known as a mild activator that is less irritating to the skin, and has been favorably used in recent years. N-acylamino acid salt, amphoteric surfactant, polyoxyethylene fatty acid penta A skin cleaning agent that combines erythritol ester and polyoxyethylene fatty acid alkanolamide (for example, Patent Document 1), or a liquid cleaning that combines an N-acyl acidic amino acid salt with a specific glyceryl ether and polyvalent alcohol. Agent compositions (eg, Patent Document 2) and the like have been devised. However, these cleaning agents could not reduce the sliminess during rinsing, the refreshing feeling was not satisfactory, and the creaminess of the foam was not satisfactory.
