Description

Powder type cosmetic composition with excellent adhesion and dispersibility {POWDER TYPE COSMETIC COMPOSITION WITH EXCELLENT ADHESION PROPERTY AND DISPERSION}

The present invention relates to a powder type cosmetic composition having excellent adhesion and dispersibility.

Powder-type cosmetic compositions are mainly used for applying makeup compositions such as base, BB, foundation, etc. to the skin, then holding the oil of the skin, giving a matte or soft finish, or imparting various colors to the skin surface, Its usability is high. In addition, powder-type cosmetic compositions are highly preferred by consumers because they can design the appearance of products in various forms and impart various colors compared to formulations with flowability such as toners, toners, essences, and creams.

Such a powder-type cosmetic composition is mainly applied on a cosmetic film formed of makeup compositions such as sunscreen, base, BB, foundation, etc., rather than directly applied on the skin surface, so high adhesion is required. In addition, as it is prepared by mixing a binder including oil, wax, etc. with powder as a main component, high dispersibility is required for characteristics such as uniform color and spreadability without clumping.

On the other hand, so far, as disclosed in Korean Patent Publication No. 10-2018-0017811, development has been conducted for the main purpose of improving the skin application feeling of a powder-type cosmetic composition and moldability during manufacture. Development of a powder-type cosmetic composition with improved adhesion and dispersibility at the same time is insufficient.
