Abstract

The invention discloses high-pigment-content pure oil non-emulsification cosmetic color paste and a preparation method. The color paste is prepared from, by weight, 65-85% of pigment, 0.2-2% of a dispersing agent, 0.2-2% of stabilizer and 12-35% of grease. The high-pigment-content pure oil non-emulsification cosmetic color paste is characterized in that the pigment content is high, and the color paste belongs to pure oil non-emulsification color paste. The utilized pigment, the grease, the dispersing agent and the stabilizer are all raw materials which are allowed to be used by a China Cosmetic Ingredient Dictionary, a product is high in solid content, high in covering power, good in stability, high in safety, convenient to use, free of water, easy to add, easy to scatter, simple in preparation process and easy to produce, is the best substitute of traditional powdery pigment and is suitable for the field of cosmetics, food and the like.

Description

technical field [0001] The invention relates to the field of cosmetic raw materials, in particular to a pure oily color paste for cosmetics. Background technique [0002] There are many shortcomings in the use of traditional cosmetic grade powder pigments in cosmetic formulations. The surface energy level of powder pigments is large, and the particles are easy to agglomerate, which increases the difficulty of powder dispersion, especially in the process of color blending. Difficult and uneven dispersion reduces the coloring power and hiding power of pigments, and easily forms color spots and chromatic aberration. At the same time, powder pigments will generate floating dust during application, which not only causes the loss of raw materials, but also seriously affects health and pollutes the environment. [0003] Most of the pigments used in cosmetics on the market are still powder pigments, and few paste pigments are used. Existing oily color paste, for example: applicat...
