Description

  The present invention relates to a skin cleanser composition that reduces irritation of a cleansing agent without deteriorating foam performance and is excellent in skin feel after cleaning.

Conventionally, it has been known to remove higher fatty acid salts from detergent compositions for the purpose of improving mildness such as itching and lack of feeling of bulkiness. It was recognized that the foam performance such as the property and the amount of foam was insufficient.
In addition, when powder is used together to improve the skin feel after washing, such as smoothness and smoothness, irritation such as itching and tingling sensation occurs during washing, and the powder does not remain on the skin. A defect that the skin feel was not obtained was recognized.

  As a technique for solving these problems and the like, for example, a detergent composition that improves mildness to the skin by using a low-irritant surfactant without using a higher fatty acid salt (for example, Patent Document 1). However, there is a problem that it is not yet satisfactory in terms of usability such as foaming at the time of washing and sliminess.

In addition, the powder having specific physical properties is used in combination to improve the skin feel. For example, the average particle diameter is 0.1 to 100 μm and the pore volume is 0.5 ml / g or more. A detergent composition characterized by containing a certain spherical porous silica (for example, see Patent Document 2), an average particle diameter of 0.1 to 100 μm, and an oil absorption of 0.5 ml / g or more. A cleaning composition containing a spherical fine particle inorganic pigment and a water-soluble polymer is known (for example, see Patent Document 3).
However, each powder used in these cleaning compositions physically gives skin irritation because of its large particle size, and also has a problem that the effect of reducing external irritation is not sufficient because it cannot remain in the details of the skin. There is something.
