Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition having an appearance of various colors,

The present invention relates to a cosmetic composition which realizes a brilliant hue according to an angle and a light source without using an inorganic pigment and a dye as a pigment.

Recently, trend of cosmetics is characterized not only by the excellent performance of the product itself, but also by designing the product package or container, designing the color or form of the product itself, thereby giving different visual differentiation from the existing product. Grant plays a crucial role in selecting a product for purchase by the consumer.

In general, the cosmetic product of the oil cosmetic can be used both oil phase and water phase, so that it can realize both advantages of both. There have been many attempts to modify the shape and color of the formulations to enhance the palatability of such cosmetic products. For example, in order to impart the characteristics of a product to a transparent cosmetic composition using a microemulsion or a refractive index matching method, an inorganic pearl or bead coated with titanium dioxide on mica or alumina or a pigment such as an inorganic pigment or a dye is used Coloring has been carried out.

However, when coloring using an inorganic pigment as a coloring matter, it is difficult to provide a transparent cosmetic composition because of a large refractive index difference between the refractive index of the inorganic pigment and the dispersion medium.

In addition, when a dye is used as a coloring matter, there is a problem in preservability because it is frequently discolored under direct sunlight or fluorescent light.

Korean Patent No. 10-0908360 is made up of a liquid separated into two phases whose refractive index coincides with each other in the wavelength range of 400 nm to 800 nm and is colorless before mixing the liquid phase of two phases, It discloses a color-forming composition which develops color.

Accordingly, the present inventors aim to provide a color cosmetic composition which realizes a brilliant hue without using an inorganic pigment and a dye as pigments in a transparent emulsion cosmetic composition in order to solve the above-mentioned conventional problems.

In order to attain the above object, the present invention provides a water-based cosmetic composition comprising a mixture of an aqueous phase and an oil phase, wherein the aqueous phase is composed of purified water and glycerin, and the oil phase comprises a coloring cosmetic composition comprising silicone surfactant, silicone elastomer, oil and organic UV- Lt; / RTI >

Experimental Example  One : Color  Evaluation of Strength

The color intensity of the cosmetic prepared in Examples and Comparative Examples was visually judged and evaluated by a panel of 10 males and 10 females to determine the color development intensity of each of the test samples from the number of panels that felt the color intensity . The results are shown in Table 2 and FIG.

 <Evaluation Criteria>

◎: More than 18 people felt that they were developing.

○: More than 10 people, less than 18, felt that they were developing.

△: More than one person, less than 10 people, felt that they were developing.

X: 0 people who felt that they were developing.

Experimental Example  2: Evaluation of transparency

The transparency of the cosmetic compositions prepared in Examples and Comparative Examples was visually judged and evaluated by a panel of 10 males and 10 females and the transparency of each of the test samples was judged based on the following criteria based on the panel acceptance. The results are shown in Table 2 below.

 <Evaluation Criteria>

◎: More than 18 people felt transparent.

○: More than 10 people, less than 18, felt transparent.

△: More than 1 person, less than 10 people felt transparent.

X: 0 people who felt transparent

As can be seen from the results of Table 2, Examples 2 to 5 are all transparent cosmetics, and Example 1 and Comparative Examples 1 and 2 have an opaque appearance. In the case of Example 1 and Comparative Example 1, the transparency was low even though the refractive index difference between the water phase and the oil phase was 0.001 or less, and the opacity of Comparative Example 2 was higher than that of the entire cosmetic composition with respect to the content of the organic UV blocking agent having a high refractive index This is because the refractive index difference between the water phase and the oil phase is 0.001 or more.

On the other hand, the intensity of color development was higher in Example 3 than in Examples 1 and 2, and it was confirmed that the color development intensities of Examples 3 to 5 in which transparency was different were all similarly high.

Experimental Example 3: Evaluation of stability of cosmetic composition

As shown in Table 3, the formulation stability of the cosmetic compositions of Examples 1 to 5 and Comparative Examples 1 and 2 was stored in a thermostatic chamber at different temperature conditions (4 ° C, room temperature, 45 ° C, cycling) for 4 weeks And the results are shown in Table 3.

As can be seen from the results shown in Table 3, when the total content of the organic UV blocking agent contained in Comparative Example 2 exceeds 15% by weight, the separation phenomenon occurs at almost all the temperature conditions.
