Cosmetic composition {COSMETIC COMPOSITION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, and in particular, to a cosmetic composition, particularly a lip cosmetic (lip make up) composition, in which an applied texture, uniform applicability, color developing power (expression power) and color persistence are enhanced.

Cosmetic compositions, in particular representative lip makeup compositions (all cosmetics that can be used on the lips, such as lipsticks, lip gloss, lip balms, lip pencils), color the skin (especially the lips; the same below) to make the skin look beautiful and healthy while simultaneously This is to protect it, which is made into a uniform mixture by dispersing various nutrients, organic and inorganic pigments useful for the skin in oily substances such as animal and vegetable waxes and ester oils.

That is, a cosmetic composition usually contains a solid component, a liquid oil component, a pigment | dye, other nutritional components, etc.

The solid components include candelillanab, ceresin, carnauba wax, paraffin, nap, braze, beeswax, microcrystalline lead, polyethylene, etc., which increase the hardness to maintain the appearance of the cosmetic composition, and improve the feeling smoothly. do.

However, the use of such a solid component, although giving a smooth texture, there is a problem in that it shows a hard feeling when applied to the skin by increasing the hardness.

The liquid oil phase components include castor oil, jojoba oil, squalane, lanolin oil, lanolin derivatives, oils extracted from animals and plants, and synthetic ester oils.

However, according to the use of the liquid oil-based component such as synthetic ester oil, the usability is heavy, the coating feeling is bad, and also has a disadvantage that the burden on the skin after the application and the durability of the color is not excellent.
