    • The present invention relates to a solid temporal colorimetric hydrogel cosmetic composition having flexibility by irradiation of gamma-rays, and, as an oil-in-water type hydrogel cosmetic composition comprising a water phase part and an oil phase part, is characterized in that the cosmetic composition comprises 15 to 99.90 wt% of the water phase part and 0.10 to 85 wt% of the oil phase part based on the total weight percentage of the composition, the water phase part and the oil phase part have a refractive index difference of 0 to 0.02 therebetween, the cosmetic composition has gamma-rays irradiated thereto, and the cosmetic composition is characterized by a color change according to variations in a refractive index difference between the water phase part and the oil phase difference when applying the cosmetic composition to the skin. A hydrogel cosmetic composition according to the present invention has effects that the cosmetic composition not only has flexibility through irradiation of gamma-rays, but also enables an optimal application time of the cosmetic composition to be visually confirmed through a color change from transparency to ivory white due to a change in the refractive index difference caused by absorbency and volatilization of water when applying the composition to the skin using a refractive index difference between a water phase part and an oil phase part within the composition, and has an effect that the cosmetic composition is capable of improving quality of a product although a preservative irritating to the skin is not added by inhibiting microbial proliferation of a cosmetic material.

    • The present invention relates to a cosmetic container for two kinds of cosmetics. The cosmetic container includes: an upper container 10 containing a second cosmetic and configured to be rotatable; a lower container 20 containing a first cosmetic; a handle part 30 detachably coupled to the lower end of the upper container 10 and the upper end of the lower container 20; a discharge part 40 provided so as to enable discharging of the second cosmetic. The present invention exhibits an effect in that only the desired one of the two kinds of cosmetics can be used, or the two kinds of cosmetics can be used, sequentially or mixed together, through a single tip by a simple operation of the cosmetic container. Also, the present invention enables contouring to be performed by discharging and using a necessary amount of the second cosmetic after using the first cosmetic, thus exhibiting an effect of enabling the appearance of the skin to have accentuated facial contours or have a three-dimensional effect according to the type of formulation (the first cosmetic is a BB cream, and the second cosmetic is a highlighter, shading or blusher, etc.). Also, the cosmetic container can be used as a cosmetic container for skin care and skin protection by using a cream formulation as the first cosmetic and a serum as the second cosmetic, or a sun-care formulation as the first cosmetic and a cooling product as the second cosmetic.
