The present invention relates to an oil-based solid cleansing cosmetic composition containing a face-wash powder.

Facial cleansing and cleansing are an early stage of the beauty system and are a very important cosmetic activity. Clearing away excess sebum or make-up cosmetics and proceeding to the next treatment step is a necessary condition to prevent skin trouble and protect healthy skin condition. There are both endogenous and exogenous dirts on the skin, and the endogenous ones include excessive sebum and metabolites such as keratin of the stratum corneum, and the foreign ones include dust, dust, and makeup. If sebum and makeup materials are left to oxidize, it is important to keep the skin clean because it causes inflammation, edema, pigmentation, or microorganisms that cause acne.

The cleansing cosmetics to clean the skin there are a variety of products, the shape of the creamy, latex, liquid, powder is known. In addition, when classified into a prescription configuration, the main component is an aqueous cleansing agent, an aqueous cleansing agent containing an aqueous component, an aqueous component, an oily component, and a surfactant, and an oily component, which are formulated with an aqueous component as a main component. Therefore, there are oil-based cleansing cosmetics containing a surfactant, powdery cleansing cosmetics containing a hydrophilic surfactant powder and an enzyme, and the like. In general, the ability to remove cosmetics and dirt on the skin is excellent in order of oily cleansing cosmetics, emulsified cleansing cosmetics, powdery cleansing cosmetics, and aqueous cleansing cosmetics.

Due to this change, since a sufficient cleansing force is not obtained with the conventional cleansing cosmetics, the cleansing market is also greatly changed, and the market of cleansing oil with excellent cleansing power is rapidly expanded.

However, cleansing oils have the disadvantage of flowing down from the hand when in use, despite their excellent cleansing power, and there are consumers who do not like this type of cleansing agent. In order to improve the usability disadvantages from hand, oil-based gelling agents such as organic bentonite, hydrophobized silicic acid, silicic anhydride and dextrin fatty acid ester are mixed (Japanese Patent Application No. 62-108806) or aerosol containing dextrin fatty acid ester. It is devised to make a mousse of a form (Japanese Patent Laid-Open No. 7-277954) or to use an wax such as polyethylene to form an oil-based solid cleansing agent (Japanese Patent Laid-Open No. 2001-213726). However, waxes and emulsifiers have a drawback that they are excellent in adhesion to the skin, and therefore, when used after wiping and washing off, stickiness and a greasy oiliness remain, a fresh feeling is difficult to obtain.

In addition, in the case of aqueous cleansing foam cleansing, the cleansing power is improved by using a synthetic and natural scrub agent such as polyethylene powder, hodo seed powder, and apricot seed powder with high melting point, but due to physical friction of the scrub agent, Stimulation and eye irritation are disadvantages.

Therefore, the development of a new type of cleansing cosmetics that improves the cleansing effect, improves the disadvantages of the cleansing oil flowing down, and eliminates the disadvantages of sticky and greasy oily after cleansing after use and washing off. need.
