Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a refreshing use feeling for removing dirt on the skin and makeup cosmetics.
It relates to a transparent cleansing material excellent in usability.

[0002]

2. Description of the Related Art Sebum and makeup cosmetics remaining on the skin are mainly oily stains, and a cleansing agent containing an oil as a main component has been used to remove them. Oil-based cleansing agents include oil-based components alone or oil-based cleansing agents (cleansing oil) containing a surfactant and an oil-based component, an aqueous component and an emulsified cleansing agent containing a surfactant ( Cleansing cream, cleansing milk) and the like are used depending on their usability. As a method of use, there is a method in which a cleansing agent is applied to the skin to adjust it to dirt, and then wiped off with a tissue or the like, or washed off with water.

[0003]

However, although the oil-based cleansing agent containing an oil agent as a main component has an excellent cleansing effect, the oil-based feeling remains after wiping or rinsing, and in some cases, furthermore, soap or face washing. It was necessary to wash the face using ingredients. In addition, the emulsified cleansing material has a problem that the oily feeling is reduced, but the cleansing effect, which is the original purpose, is not sufficient. Therefore, there has been a demand for development of a cleansing material which has an excellent stain removing effect, can be more easily cleansed, and has no oily feeling after use.

[0004]

Under such circumstances, the present inventors have conducted intensive studies and have found that liquid oil and HLB7
By blending the side chain fatty acid soap with the above nonionic surfactant, a cleansing effect having an excellent cleansing effect, leaving no oily feeling after wiping or washing, and having a refreshing feel can be obtained. The inventor has found that a gel-like transparent cleansing agent excellent in usability can be obtained by blending a dextrin fatty acid ester, thereby completing the present invention.

That is, the present invention is characterized in that it contains the following components (A) to (C): (A) liquid oil; (B) a nonionic surfactant having an HLB of 7 or more; and (C) a side chain fatty acid soap. It is a clear cleansing fee. Furthermore, it is a gel-like transparent cleansing agent characterized by containing the component (D) dextrin fatty acid ester. The details will be described below.

[0006]
