Description

Skin cleanser composition

The present invention relates to a skin cleanser composition.

In the skin cleansing composition, the foam performance is an important factor from the viewpoint of usability. Examples of the performance of the foam include ease of foaming at the time of washing, foam persistence, foam quality, and foam shape retention. Among these, when the ease of foaming at the time of washing and the persistence of the foam are poor, the user's satisfaction may be lowered. As a skin cleansing composition excellent in easiness of foaming, a personal cleansing composition containing polyoxyethylene alkyl ether sulfate and a betaine-type amphoteric surfactant has been proposed (see, for example, Patent Document 1). However, the above proposal has a problem that it is inferior in terms of the persistence of the foam and the ease of spreading on the skin. Moreover, as a skin cleanser composition excellent in usability and foam quality, a skin cleanser composition containing polyoxyethylene alkyl ether sulfate, betaine-type amphoteric surfactant, and alkylamine oxide has been proposed. (For example, refer to Patent Document 2). However, the proposed skin cleanser composition is not satisfactory in terms of foaming ease and foam persistence.

Furthermore, the ease of extension on the skin is also important for the feeling of use of the skin cleanser. So far, a skin cleanser composition has been proposed that contains polyoxyethylene alkyl ether sulfate, a betaine-type amphoteric surfactant, and a specific nonionic surfactant and is excellent in stretchability on the skin. (For example, refer to Patent Document 3). However, the above proposal has a problem that the skin cleansing composition is less likely to foam, and the skin becomes sticky on the dry wrinkles after washing.

Therefore, it is desired to provide a skin cleanser composition that is easy to foam and has a good persistence of foam, is easy to stretch on the skin, and has excellent dry wrinkle skin stickiness after washing.
