Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, and more particularly to a cosmetic composition having a high emollient effect, preventing skin dryness and being excellent in usability.

[0002]

2. Description of the Related Art Originally, the skin has a function of appropriately suppressing the evaporation of water from the body, but if it is placed in an extremely dry environment or if the skin becomes rough, its function deteriorates. The skin becomes rough. In such cases,
It is known that by applying an appropriate oil content to the skin, the moist skin is restored and abnormal evaporation of water is suppressed. Among them, cholesterols have a high water-holding ability and can further improve the smoothness and moistness of the skin.

[0003]

However, when cholesterols are used alone or in combination with a non-polar oil, they cause a problem as a cosmetic in terms of stickiness and the like.

[0004]

In view of such circumstances, the present inventors have conducted earnest studies to obtain a cosmetic having a high emollient effect and an excellent use surface, and as a result, a cholesterol derivative and a polyvalent compound were obtained. The inventors have found that the above problem can be solved by using a fatty acid ester of alcohol together, and have completed the present invention. That is, the present invention is
A cosmetic comprising one or more cholesterol derivatives and one or more esterified products of a polyhydric alcohol and a fatty acid.

The structure of the present invention will be described in detail below. Cholesterol derivatives used in the present invention include cholesterol, cholestanol, dehydrocholesterol, lanolin fatty acid cholesteryl, cholesteryl isostearate, cholesteryl 12-hydroxystearate, cholesteryl ricinoleate, macadamia nut oil fatty acid cholesteryl and the like. The amount of the cholesterol derivative used in the present invention is 0.01 to
30% by weight is preferred. If it is less than 0.01% by weight, the effect tends not to be exhibited, and if it exceeds 30% by weight, it is not preferable in the process of the product.

Examples of esterified products of polyhydric alcohols and fatty acids used in the present invention include pentaerythritol tetra-2-ethylhexanoate and glycerin tri-2-ethylhexanoate. The amount of the esterified product of the polyhydric alcohol and the fatty acid used in the present invention is preferably 0.01% by weight or more based on the total amount of the cosmetic. If it is less than 0.01% by weight, the stickiness of the cholesterol derivative cannot be suppressed.
