Description

Skin Cleanser Composition {SKIN CLEANSING AGENT COMPOSITION}

The present invention relates to a skin cleanser composition.

The speed | rate of foaming and the amount of foaming of a skin cleanser composition are one of important product quality from a viewpoint of the satisfaction of cleaning power, etc. in a consumer. In recent years, outgas agents such as body creams in which oil and silicone are blended are often used (see Patent Document 1), and there is a problem that the foaming of the skin cleanser composition is deteriorated. Similarly, even when used for skin where contamination such as oil or silicone exists, a foaming skin cleanser composition is desired.

As a method of making foaming of a skin cleaning composition favorable, the method of increasing the compounding quantity of a cleaning agent (anionic surfactant, an amphoteric surfactant, a nonionic surfactant, etc.) is mentioned. Furthermore, the body cleaning composition containing any of a long-chain fatty acid, N-acyl- (alpha)-alanine, a polyhydric alcohol, a high molecular compound, an inorganic salt, an amphoteric surfactant, and the acylamino acid alkali metal ( Patent Document 2), a skin cleaning composition containing a silicate having a hemoglobin aggregation action, a fatty acid salt (see Patent Document 3), and the like have been proposed.

However, these detergent compositions have a problem that slipperiness occurs at the time of rinsing, and it is difficult to rinse, or there is a problem that irritation to the skin occurs such as feeling the pulling of the skin, feeling sticky after towel drying. Moreover, the speed | rate of foaming and the amount of foaming were also not fully satisfactory.

In order to eliminate the pulling feeling of skin, the detergent composition which aimed at the improvement of the mildness to skin by using together polyethyleneglycol and a specific hypoallergenic surfactant is proposed (refer patent document 4 and 5).

However, when these cleaning compositions are used, unpleasant "slipiness" occurs at the time of washing, not only the rinsing property is impaired, but also there is a problem that a sticky feeling occurs after drying.

Therefore, the present condition is strongly desired to provide a skin cleansing composition which is quick to foam, has a large amount of foam, is excellent in rinsing property, and does not have a sticky feeling and a feeling of pulling after drying.
