Cosmetic composition for concealing immediate blemishes {Make-up cosmetic composition having immediate effect}

The present invention relates to a cosmetic composition capable of immediately concealing skin imperfections, and more particularly, to a cosmetic composition containing a specific silicone elastomer and powder having a remarkably excellent immediate concealment effect of skin imperfections.

[0003] Recently, women have increased the desire to make the skin look smooth by improving the curvature of the skin while maintaining the color of the skin for natural makeup. Therefore, studies on cosmetics that show natural skin color and make the curves of the skin look smooth are being actively conducted with only basic cosmetics, and products that compensate for skin defects as soon as they are applied are being released.

Conventional cosmetic compositions for improving skin conditions such as skin wrinkles or skin elasticity tend not to show an immediate skin improvement effect when applied to the skin. Some of the above problems can be solved by using some silicone elastomers or spherical powders, but since a large amount must be used for an effect, the formulation becomes hard and the feeling of use becomes heavy, resulting in poor application. In addition, wax and higher alcohol components are precipitated over time at low temperatures, and stability may be deteriorated, and a shedding phenomenon due to association of elastomers occurs severely, resulting in a loss of value as a product. As a way to solve this problem, there is a method of reducing the content of elastomer and increasing the content of powder, but in this case, another problem that cannot achieve stabilization of the formulation occurs.

The problem to be solved by the present invention is excellent in immediate concealment of skin defects such as wrinkles, less slipping during makeup, good feeling of use, and containing a high content of powder, providing a cosmetic composition for concealing skin defects with excellent formulation stability is to do

In order to achieve the above technical problem, the present invention provides an oil-in-water cosmetic composition for concealing defects comprising a silicone elastomer and powder.

The inventors of the present invention improved the effect of concealing skin defects along with the stability of the formulation of the cosmetic, while striving to minimize the creeping phenomenon that occurs seriously in the cosmetic containing a large amount of silicone elastomer and powder, the specific When silicone elastomer and powder, especially hemi-spherical PMMA powder, are combined, the association of elastomers is suppressed, oil absorption is increased to prevent shedding, and it is found that the effect of hiding skin blemishes is excellent Thus, the present invention was completed.

In the present invention, the meaning of the 'concealment of defects' includes covering wrinkles or pores of the skin, making the skin texture look fine and smooth, and the like.

For the compositions prepared in Comparative Example 1 and Examples 1 to 6, skin defects (wrinkles, pores, skin texture) concealment experiments and stability were evaluated, and detailed evaluation methods and results are as follows.

Experimental example 1: Evaluate the effect of concealing fine wrinkles (wrinkles around the eyes)

In order to confirm the immediate effect of concealing fine wrinkles of a formulation containing powder and silicone elastomer, wrinkles around the eyes were measured on 10 women in their 30s and 40s. The instrument used was PRIMOS (Phaseshift Rapid In vivo Measurement of Skin, GFMesstechnik GmbH, Germany), and wrinkles around the eyes were measured with the face fixed to a set of fixed equipment for measurement. The same area was measured at every measurement, and the subject was measured after fixing the test subject to a set of specially designed PRIMOS measurement fixtures to prevent contraction, relaxation and movement of the skin at the measurement area. In the 3D measurement of PRIMOS, the parallel projection stripes projected onto the skin change according to the height difference of the skin surface, and the degree of this change is quantitatively calculated by a computer. The image of wrinkles around the eyes measured by PRIMOS is matched with the measurement area using 3D Matching. When the value of the variable (Ra) decreases, it means that wrinkles around the eyes are improved. The variable (Ra) value measured by PRIMOS means the arithmetic average value of the highest values of the profile within the entire measurement range, and the improvement rate was calculated as follows.
