Abstract

Disclosed is an oily cosmetic which comprises: (a) 50 to 99 mass% of an oily phase which has a liquid form at 25 DEG C; (b) 1 to 7 mass% of dextrin (palmitate / 2-ethylhexanoate); and (c) 0.001 to 10 mass% of a coloring material and / or a pearlescent agent other than a laminated film powder, and which has a viscosity of 3000 to 20000 mPa s as measured on a BL viscometer at 30 DEG C. The oily cosmetic may further comprise (d) silicic acid anhydride and / or hydrophobized silicic acid anhydride.

Description

technical field [0001] The present invention relates to oil-based cosmetics, and more particularly, to oil-based cosmetics and cosmetic preparations capable of stably dispersing colorants and / or pearlescent agents while maintaining fluidity. Background technique [0002] Oil-based cosmetics are cosmetic formulations widely used in eye color, eyebrow pencil, lipstick, etc., by changing the composition of solid oil, semi-solid oil, liquid oil, coloring pigment, bright pigment, constituent powder, etc. type and / or content to make various functions and / or textures, hues, etc. concrete. These textures, color tones, and the like are important elements in cosmetic cosmetics, and various techniques have been proposed. For example, a colorant containing a pearlescent material based on mica and / or a laminated powder containing polyethylene terephthalate / metal / epoxy resin has been developed (Patent Documents 1, 2), which are made of aluminum, A colored metallic pigment in which a lay...
