Description

  The present invention relates to eye makeup cosmetics.

Eye makeup cosmetics are divided into emulsified types and oily types. These are produced by adding a pigment, powder or polymer emulsion to a base obtained by emulsifying or dispersing a solid or semi-solid oil in water.
Such eye makeup cosmetics have good adhesion to the skin and eyelashes and mascara has the advantage of curling up and volume up, but it is based on particles dispersed in water or oil. Since the agent itself is cloudy and not transparent, and the particles impair the uniformity of the film even after drying, there is a problem that the coating film is not smooth and gloss is not felt during and after application.

As a cosmetic for eyelashes that gives the eyelashes a glossy appearance, a cosmetic for eyelashes containing a water-soluble carboxyvinyl polymer, a basic substance and dextrin has been proposed (see Patent Document 1). This cosmetic for eyelashes has a problem that it is glossy but has low water resistance, so it dissolves in tears and eye drops and the eyelashes become sticky.
In addition, an oil-in-water type high gloss mascara containing a glossy film forming agent, a thickener and a wax has been proposed (see Patent Document 2). This high gloss mascara has a certain degree of gloss, but has low water resistance and sebum resistance and insufficient makeup persistence.
Furthermore, cosmetics for water-in-oil eyelashes containing inulin and / or inulin fatty acid ester, wax and candelilla resin have been proposed (see Patent Document 3). This cosmetic for eyelashes has a problem in that the base is opaque, so that it does not feel gloss when applied.
