Description

  The present invention relates to a liquid skin cleanser product in which the rinsing time is shortened by reducing the slickness during rinsing.

  Conventionally, skin cleansing agents have been preferred for a refreshing feel after washing, and higher fatty acid salts have been used as washing bases. However, while the fatty acid salt is refreshed after washing, it has a drawback that it takes time for rinsing because it is slippery during rinsing.

  A detergent containing an anionic surfactant has been proposed in order to reduce the slickness during rinsing, but it is difficult to remove the slickness with an anionic surfactant alone, so it is hydrolyzed with a sugar alcohol derivative. Attempts have been made to increase the refreshing feeling after rinsing even when the plant protein is blended and even when it feels slippery during rinsing. However, the coexistence between the refreshing feeling after rinsing and the shortening of the rinsing time is not sufficient (Patent Document 1: Japanese Patent Application Laid-Open No. 2010-180182).

  On the other hand, attempts have been made to improve foam quality by blending a cationic polymer, but coexistence with shortening of the rinsing time is still insufficient (Patent Documents 2 and 3: JP 2004-204087 A). JP, 2005-15359, A). Although a cleaning agent having improved foam quality by blending a polyol has been proposed, the effect of shortening the rinsing time has not been sufficient (Patent Document 4: JP-A-2002-080345).

  In any case, there is currently no skin cleanser that can be rinsed in a short period of time, the rinse time is fast, the foam is elastic and foamy, and a refreshing feeling is obtained after rinsing. There is no known skin cleanser that can be used in former containers.

(C) When sugar alcohol is added, the refreshing feeling after washing increases, and the elasticity of foam discharged from the former container can be increased by filling the former container with this composition. The headline and the present invention were made.

Accordingly, the present invention provides the following liquid skin cleanser products.
