Skin cleanser composition in a former container

The present invention relates to a skin cleanser composition contained in a former container.

In the skin cleanser composition contained in the foamer container, from the point of usability, the foam performance such as the fineness of the foam (hereinafter, may be referred to as "the texture of the foam"), elasticity of the foam, and the shape of the foam are important factors. , various studies such as increasing the amount of various active agents and combinations thereof have been conducted so far, and improvement of foam performance has been tested (see, for example, Patent Documents 1 and 2).

Moreover, the technique of improving foam performance by combining an amphoteric surfactant with an anionic surfactant is also proposed (for example, refer patent document 3).

According to the above proposal, excellent foaming performance can be achieved, but the formulation viscosity increases due to the combination of the anionic surfactant and the amphoteric surfactant, thereby increasing the pressing pressure at the time of foaming from the pump and foaming performance. (especially the grain of a bubble) may cause a fall, and the discharge property from a former container may fall.

Accordingly, there is a strong demand for rapid development of a skin cleanser composition contained in a former container having good foam compactness, foam elasticity, and foam retention, and also excellent in dischargeability from the former container.
