Description

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.

Korean Patent Publication No. 10-2007-63908 U.S. Patent No. 6,932,984 European Patent No. 2,277,982

It is an object of the present invention to provide a cosmetic composition which uses a destructive color change microcapsule having excellent color bleed resistance and shatter resistance and which can provide a makeup composition stabilizing an active ingredient with improved stability without inducing skin irritation And to provide a cosmetic composition for skin.

It is still another object of the present invention to provide a color change cosmetic composition for makeup which can easily control color development or discoloration pattern, and uniformly realize various color coordinates with a feeling of soft feeling without a foreign object.

The present invention provides, in a physiologically acceptable medium, a cosmetic composition comprising a) a core layer comprising at least one colorant, an oil-soluble active ingredient and a first binder, one or both of a core layer comprising at least one colorant and a second binder , B) an alcohol selected from polyols, diols and monools in an amount of up to 10% by weight based on the total weight of the cosmetic composition, and c) at least one hydrophilic gelling agent, to form a color change cosmetic composition for make- to provide.

As shown in Table 2, it was confirmed that the color change cosmetic composition according to the present invention can remarkably improve the stability of the oil-soluble active ingredient compared to the comparative example.

3. Color persistence evaluation

0.1 g of each formulation was uniformly applied to artificial leather of a certain area (1 cm 2) eight times reciprocally. The initial color values were measured using a colorimeter (Spectrophotometer ColorQuest XE), color values were measured in the same manner at intervals of one week, and the color difference value (ΔE) versus the initial application state was calculated by the following formula 1. At this time, the smaller the value calculated by the following formula 1 is, the smaller the color change is, and when the value is less than 1, it is commonly referred to as " no color change. &Quot;

(Equation 1)

^{△ E = (△ L 2 +} △ a 2 + △ b 2) 1/2

As shown in the above Table 3, the color change cosmetic composition according to the present invention has a color difference value (? E) of 1.0 or less, showing no change in color difference, and thus can be used stably in a formulation. This shows that the swelling characteristics of the microcapsules are appropriately controlled when the formulations are applied, thereby solving the problems of the reproducibility of the color tones expressed when the microcapsules are destroyed.

That is, the color change cosmetic composition according to the present invention can overcome the problems that occur during color development of the color change microcapsule, and can enhance the unique characteristics of the color cosmetic composition such as broad color coordination and hiding power enhancement. In addition, it is expected that the stability of the oil soluble active ingredient can be dramatically improved, thereby maximizing the skin care effect and providing pleasure in visual sense, aesthetic sensibility and pleasure of makeup.
