Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cleansing composition which is creamy, has good lather, has excellent feeling upon use, has low irritation, and can be moist and moist after washing.

[0002]

2. Description of the Related Art Conventionally, since a skin cleansing composition has a feature of high foaming properties, anionic surfactants such as alkyl sulfates, alkyl benzene sulfonates and α-olefin sulfonates have been widely used. Used. However, when these surfactants are blended in a large amount, irritation may occur, and there is a problem that a refreshing feel can be obtained after washing, but the skin feels tight.

[0003] For this reason, as surfactants having a lower irritation, sulfosuccinic acid-based surfactants, ether carboxylic acid-based surfactants, amide ether carboxylic acid-based surfactants, N-alkylamide alkanol sulfates and the like are available. Are known. However, these surfactants were not sufficiently satisfactory in terms of foaming properties and foam quality.
When using such low-irritating surfactants, in order to improve their foaming properties and foam quality, a combination of a nonionic surfactant and an amphoteric surfactant is blended. However, there was a problem that there was a sticky feeling after washing.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a skin cleansing composition which has good lathering, is excellent in use feeling, has low irritation, is refreshing after washing, and has no stickiness. It is in.

[0005]

Means for Solving the Problems Under such circumstances, the present inventors have conducted intensive studies. As a result, if an anionic surfactant and trimethylglycine are used in a specific ratio in combination, creamy and good foaming can be obtained. It is possible to obtain a skin cleansing composition that is excellent in use feeling, is low irritation, has less feeling of tightness of the skin after washing, and has a moist and moist wash while having a refreshing washing feeling. Heading, the present invention has been completed.

That is, the present invention comprises (A) an anionic surfactant and (B) trimethylglycine, and the weight ratio of components (A) and (B) is (A) / (B) = 100 /
1 to 4/1.
