Description

Cosmetic Composition Containing Silica Silylate Pellet

The present invention relates to a sebum control cosmetic composition containing silica silylate pellets, specifically, to a sebum control cosmetic composition containing silica silylate pellets comprising a core layer comprising mannitol and the like and a coating layer comprising silica silylate. will be.

Existing sebum-regulating powders use powders having high oil absorption capacity such as silica. For example, porous powders such as porous silica and porous cellulose are widely used as sebum control agents. However, the porous powder has difficulty in forming into a water phase due to low wetting power.

U.S. Patent No. 5,683,706 discloses a powder cosmetic composition containing two types of talc having different particle sizes, and discloses a method of controlling sebum by using powders having high oil absorption power such as silica as a sebum oil absorber. The method uses a large amount of powders having a large oil absorption power to concentrate only on simple sebum oil absorption, resulting in severe skin pulling after use, and when used in a small amount, the persistence of sebum oil absorption deteriorates and the skin becomes shiny due to the absorbed sebum. And the like.

Korean Registered Patent No. 10-1062430 discloses a micron capsule composition for a sunscreen containing nano-inorganic powder, which is more friendly to the human body, by dispersing an inorganic sunscreen using a natural surfactant, and a method for manufacturing the same.

However, most of the powders having excellent skin absorption capacity are not stably dispersed in water, and thus the powder form is difficult to use for basic cosmetics in addition to color cosmetics.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a cosmetic composition having excellent sebum control ability, including silica silylate pellets.

The above object is achieved by a cosmetic composition for sebum control comprising silica silylate pellets.
