Description

Cosmetic composition for lips containing a large amount of pearl {LIP COSMETIC COMPOSITION HAVING A LARGE AMOUNT OF PEARLS}

The present invention relates to a cosmetic composition for lips containing a large amount of pearl, and specifically, to a cosmetic composition for lips comprising at least one of polyacrylate crosspolymer-6 and hydroxyethylacrylate/sodium acryloyldimethyltaurate copolymer It relates to a cosmetic composition for lips that stabilizes a large amount of pearls, including an agent, and has excellent lasting and moisturizing power.

Lips are the most mobile parts of the body, and because they are always exposed to the outside, they are greatly affected by environmental factors such as atmospheric and climatic conditions, so they dry out easily or age quickly. In particular, unlike the general skin structure of the lips, the skin structure of the lips does not have sebum and pores, and the stratum corneum is formed very thinly, so the absolute amount of natural moisturizing factors and moisture is insufficient, and the water evaporation rate is very fast. Because lip care products that protect lips are used repeatedly every day or over a long period of time in daily life, they must be safe to use and have no side effects.

The trend of makeup is changing according to the times, and recently, due to Corona 19, people are constantly wearing masks, and accordingly, mask makeup with high durability without sticking to the mask is becoming popular.

In general, lipstick is an oily formulation and consists of wax, oil, pigment, and powder. The wax maintains the appearance of the lipstick, the oil gives a rich feeling of use and a glossy feeling, the pigment shows a color as a pigment and/or dye, and the powder gives a matte feeling with improved spreadability, adhesion, and durability use for

In addition, in the case of the cosmetic composition of the water dispersion type, it has the characteristic of having a moist feeling due to the content of water, but the moisture feeling disappears over time due to the rapid evaporation of water, so it has a dry feeling. It has a weakness problem. In order to solve this problem, when the content of the polymer used as a conventional thickener is increased, there are problems such as stickiness and heavy feeling of use, so there is no satisfactory improvement.

In addition, Carbomer, which is conventionally used as a thickener in most lip makeups for lips, dries quickly and has a problem that keratin appears and glossiness is lowered. Contamination is controversial and its use is restricted in organic and natural cosmetics.

Accordingly, the present inventors overcame the problems of the prior art as described above, and developed a cosmetic composition for lips that has high lasting power and excellent moisturizing power without sticking to the mask, leading to the present invention.
