Abstract

An emulsified color cosmetic composition according to the present invention contains, in cosmetics, a lake pigment of which the surface is modified by an organic compound having a hydrophobic group so as to prevent the lake pigment dispersed in an oil phase from moving to a water phase, thereby preventing the lake pigment from reacting with water such that discoloration and color bleeding are prevented even in color cosmetics in an emulsified formation containing water. Thus, it is possible to provide emulsified color cosmetics capable of expressing various colors.

Description

Emulsifying Tint Cosmetic Composition

The present invention relates to an emulsified color cosmetic composition with improved discoloration of the lake pigment.

Cosmetic compositions, in particular all cosmetics that can be used on the lips, such as lipstick, lip gloss, lip balm, etc. are intended to color the skin (particularly the lips) to look beautiful and healthy while protecting the skin. Existing lip cosmetic compositions typically contain solid ingredients, but include liquid oily ingredients, pigments and other nutritional ingredients.

There is a growing demand for fresh, moist lipstick products, but there is a limit to express such a feeling with conventional oil-dispersed formulations. Therefore, emulsified lip products including oil and water awards continue to be released. Generally, the rake pigments used in oil-dispersed lip products are also used in such emulsified lip products, but the rake pigments react with water in the water to cause discoloration reactions. There is a limit to using.

Therefore, there is a need for a study on an emulsified composition that is stably dispersed in an oil phase even in a water-containing composition and does not exhibit discoloration and color bleeding of the lake pigment.

Accordingly, the present inventors have studied to develop an emulsion-type color cosmetics in which rake pigments are stably dispersed even in an oil phase. As a result, when the rake pigments whose surface is modified by an organic compound having a hydrophobic group are dispersed in an oil phase, the rake pigments receive an oil phase. By preventing the transfer to the rake pigment caused by the water-containing composition to prevent the discoloration reaction was confirmed that it is possible to express a variety of colors to complete the present invention.

Accordingly, it is an object of the present invention to provide an emulsified color cosmetic composition comprising a lake pigment whose surface is modified so as not to react with water even in the color cosmetics of an emulsified formulation containing water.

As a means for solving the above problems, the present invention

An aqueous phase comprising purified water;

Oil phase components; And

An emulsified color cosmetic composition comprising a lake pigment surface-modified by an organic compound having a hydrophobic group is provided.
