Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a skin cleansing composition which is excellent in the function of removing corneal plugs of the skin or scalp, is hypoallergenic and highly safe.

[0002]

2. Description of the Related Art Conventionally, a scrubbing agent, clay (mud stone) and the like have been used in cleaning compositions for the purpose of removing dirt from pores and old keratin. Apricot kernels, almond seeds, walnut shells, etc. may be used as scrubbing agents,
These scrubs are hard, highly irritating to the skin, and have often been regarded as a safety issue.

Agar is known to be used as a water-soluble solidifying agent, a thickening agent, a capsule forming agent and a granulating additive. Cork has excellent resistance to deterioration against chemicals, so it can be used as a container stopper or packing,
As shown in 1 and Japanese Patent Publication No. 9-511010, it is known to be used as a component for adsorbing dirt and active ingredients. Dextrin is mentioned as one of water-soluble polymers, and is used in the food field for the purpose of improving the preservability of jam, sausage and the like. However, it is not at all known that agar, cork, and a skin cleansing composition that uses dextrin as a powder, and that this skin cleansing composition has an excellent function / effect of removing horn plugs of the scalp and skin. It was The term “keratin plug” as used herein refers to sebum secreted by the sebaceous glands existing around the pores.

[0004]

DISCLOSURE OF THE INVENTION The present invention has a superior function of removing keratin plugs, which are sebum secreted from the sebaceous glands present around the pores of the scalp and skin, and is hypoallergenic and highly safe for skin cleansing. The purpose is to provide a composition.

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that a skin cleansing composition containing a surfactant has a polysaccharide powder, particularly an agar powder, a cork powder, The present invention has been completed by discovering that the inclusion of one or more poorly soluble dextrin powders results in low irritation, high safety, and excellent keratin plug removal function.

That is, the present invention is as follows: 1. A skin cleansing composition comprising a surfactant-containing skin cleansing composition containing a polysaccharide powder. 2. The skin cleansing composition according to 1, wherein the polysaccharide powder is one or more of agar powder, cork powder and sparingly soluble dextrin powder. 3.

The composition for cleansing skin according to any one of 1 to 3, which has low irritation.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The polysaccharide powder used in the present invention is
It is preferably selected from the group consisting of agar powder, cork powder and sparingly soluble dextrin powder, and one kind or a combination of two or more kinds can be used. The agar powder is agarose, [4-O- (β-D-galactopyranosyl)-
3,6-anhydro-L-galactose] is a main component of a polysaccharide having a repeating unit. It is not limited to the raw algae / production method, etc., and may be any as long as it can be mixed with cosmetics.
Agar treated with an enzyme or the like may be used. For example, it is commercially available as "Ultra Agar" (manufactured by Ina Food Industry Co., Ltd.) and can be used.

Any cork powder may be used as long as it is incorporated into cosmetics.
