DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a skin cleanser. More specifically, the present invention relates to a skin cleanser having a high makeup removing effect and excellent foaming.

[0002]

2. Description of the Related Art Conventionally, cleansing foams, facial cleansing gels and cleansing oils containing an oil component containing a surfactant as a main component have been used for the purpose of removing makeup cosmetics adhering to the skin.

[0003]

However, cleansing foams and facial cleansing gels remove the film such as silicone resin of makeup cosmetics by the detergency of a surfactant, and have the advantage of being well foamed and of being able to be easily removed. On the other hand, the effect of removing makeup is not enough.

[0004] In addition, the cleansing oil has a problem that it dissolves the film of makeup cosmetics well and has an excellent cleaning effect, but it does not foam and does not give a refreshing finish. Since the silicone resin contained in makeup cosmetics is soluble in oil, the concept is that it would be conceivable that if oil was incorporated into a surfactant-based formulation, the purpose would be fulfilled, but ordinary oil would dissolve in water. Instead, since a surfactant is used to solubilize or emulsify this oil, this concept does not foam and gives a refreshing skin feeling.

[0005] The present inventors have conducted intensive studies in view of the above-mentioned problems, and as a result, have found that a skin cleanser containing a specific oil component and a surfactant has a high makeup removing effect, is excellent in foaming, and can be washed off completely. The present invention has been completed.

[0006] It is an object of the present invention to provide a skin cleanser which has a high makeup removing effect, is excellent in foaming, and can be washed away.

[0007]
