BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color changing cosmetic composition for make-

The present invention relates to a color change cosmetic composition for make-up, and more particularly to a color change cosmetic composition for make-up comprising destructive microcapsules having a core layer and a shell layer containing an oil-soluble active ingredient.

In general, makeup cosmetic products are used for the purpose of skin flaw cover, bright skin expression, skin protection from ultraviolet rays, and control functions for sweat and sebum. Especially, when the control function for sweat and sebum, which is represented by persistence of makeup, is not secured, the makeup collapses, and functions such as cover, skin expression and skin protection can not be operated properly. Accordingly, many methods have been developed for improving the makeup persistence, and specifically, various methods of surface treatment of particles, complexation of particles, and transformation of a particle have been proposed.

Recently, color change microcapsules have been proposed for the purpose of enhancing the aesthetic effect of makeup cosmetic products. These color change microcapsules hid the color of the colorant and are used or applied on the surface of the skin, The color of the hidden colorant is revealed. A conventional technique using such a color change microcapsule will be described as follows.

Patent Document 1 discloses a pigment surrounded by a capsule film having pressure collapsibility. However, the capsule membrane of Patent Document 1 is made of collagen, gelatin, agar, or algin, and is not only susceptible to the storage conditions (stability at the aqueous phase) of the cosmetic composition but also develops a phenomenon in which colors are exuded into the liquid matrix through the capsule membrane over time And the like.

Also, Patent Document 2 discloses a method for producing microcapsules comprising at least one polymer wall material selected from a dye and a polyacrylate, a polymethacrylate, a cellulose ether, a cellulose ester, and a polystyrene maleic anhydride copolymer. Patent Document 3 discloses a cleaning composition comprising a core (A) of a colorant granule and a microencapsulated colorant granule constituting a shell (B) comprising a wall-forming polymer and a colorant. However, all of these deteriorate the visual effect of the product and the stability of the formulation due to the gradual release of the colorant in the microcapsule or the bleeding phenomenon (blurring phenomenon) caused by the coloring agent during the temperature raising process or the leaching phenomenon The problem was not completely solved.

In order to solve the problems of the prior art, the present applicant has proposed a color change microcapsule in which physical properties such as bleed resistance and shatter resistance in a formulation are remarkably improved, The present invention has been completed to provide a color change cosmetic composition for make-up comprising an oil-soluble active ingredient capable of maximizing the stability of the composition.
