Description

[0001] Cosmetic composition for lip [0002]

The present invention relates to a cosmetic composition for lips excellent in spreading, moisturizing, glossiness, pigment dispersion and high-temperature stability.

Lip is the part that connects the oral mucosa to the normal skin. It is thinner than normal skin and unlike other skin, it does not have sebaceous glands and pores. Therefore, there is no secretion of sweat sebum and lipid barrier and natural moisturizing factor (NMF) It is much lower than the skin and is easily prone to moisture loss and dryness. In consideration of the characteristics of such lips, the cosmetic composition for lips has been studied mainly on functions such as color persistence, coloring power, moisturizing power, tinting strength, etc. However, there are technical difficulties in satisfying these functions at the same time.

The lip cosmetic used for the lips is to protect the lips skin while giving a luster to the lips so as to make it look beautiful and healthy. This is to protect the lips skin by adding various nutrients useful for the skin to oily substances such as vegetable wax and ester oil , Organic and inorganic pigments are dispersed into a homogeneous mixture.

In particular, cosmetic composition for lips is an important factor in imparting color, so it is important to disperse various organic and inorganic pigments to make a uniform mixture, and to select oily substances having excellent wettability and luster. Also, since most processes such as lipstick, lip balm, lip gloss, and lipstick used in most cosmetic compositions for lips include a high-temperature process for dissolving solid components, the components of the composition used must have excellent stability at high temperatures Do.

As a method for improving the gloss upon application to the lips of a lip cosmetic composition, a method of improving the gloss of a coating composition by containing a high amount of high-gloss oil component is widely used. Most of the viscous oils have high gloss, It is disadvantageous in that it has poor viscosity and dispersibility of pigment. On the other hand, when the viscosity is low, softening ability and pigment dispersibility are increased, but the stability at high temperature is lowered.

DISCLOSURE OF THE INVENTION The present invention has been made to solve the disadvantages of the above-mentioned conventional cosmetic composition by incorporating diisotridecyl malate (DI-ITA-malate) into the composition to provide a cosmetic composition excellent in spreading, moisturizing, glossiness, pigment dispersion and high- And the present invention has been completed.

Accordingly, the present invention provides a cosmetic composition for lips excellent in gloss, spreadability, moisturizing power and pigment dispersibility when applied to skin and excellent in high-temperature stability without a high viscosity.
