Description

Eye make-up cosmetic composition containing an acrylate-based copolymer {Eye Make-up Cosmetic Composition Comprising Acrylate-based Copolymer}

The present invention relates to an eye makeup cosmetic composition.

Eye-makeup cosmetics include, for example, shadow, mascara, liner, and the like.

Shadows are mainly used on the eyelids between the eyes and the eyebrows to make the eyes stand out. Eye shadow makeup compositions are largely classified into powder type, cream type, liquid type, etc. according to formulations. For shadows, it is important to increase color development and durability, and for powder types, minimizing powder scattering is an important factor.

Mascara is applied to hairs such as eyebrows and eyelashes to compensate for the disadvantages of the shape or to give beauty to the eyes. Characteristics required of mascara, especially mascara applied to eyelashes, are to provide a sense of volume when applied, provide curling and long lash functions, and apply evenly so as not to spread easily in sweat, tears, and oil, and not to fly powder.

In addition, the liner is used on the mucous membrane around the eyes, on the double eyelid line, or on the eyelids to make the eyes look clear and large. Eyeliner is classified into liquid eyeliner, brush pen eyeliner, pencil eyeliner, and gel eyeliner depending on the container and formulation. Important properties required for eyeliner include durability, friction resistance, water resistance, oil resistance, blackness, and drying speed.

Due to the nature of the formulation, it is common that the water dispersion composition is easily erased when it comes in contact with water such as tears, and the oil dispersion composition has a problem of spreading well along the oily eye area. However, there is a demand for a product capable of providing strong durability to both moisture and oil due to its nature applied around the eyes.

In order to solve the above problems, an object of the present invention is to provide an eye makeup cosmetic composition exhibiting strong durability against both oil and moisture.

The present invention provides an eye makeup cosmetic composition. Specifically, the present invention includes an aqueous phase part, a pigment, and an acrylate-based copolymer, wherein the aqueous phase part contains a polyol and water, and the acrylate-based copolymer has a glass transition temperature of -25 to 15 ° C. It provides an eye makeup cosmetic composition comprising a first acrylate-based copolymer and a second acrylate-based copolymer having a glass transition temperature of 0 to 40 °C.

In the cosmetic composition of the present invention, the acrylate-based copolymer is included in an amount of 2 to 25% by weight based on the total weight of the composition.

In the cosmetic composition of the present invention, the first acrylate-based copolymer is an acrylate/ethylhexyl acrylate copolymer (Tg: -13 ° C), and the second acrylate-based copolymer is styrene. / Acrylates / ammonium methacrylate copolymer (Styrene / Acrylates / Ammonium Methacrylate Copolymer, Tg: 19 ℃).

In the cosmetic composition of the present invention, the acrylate/ethylhexylacrylate copolymer and the styrene/acrylate/ammonium methacrylate copolymer are included in a weight ratio of 55:45 to 65:35.

In addition, the silicone acrylate in the cosmetic composition of the present invention, the composition may additionally include an oil phase and a surfactant.

The eye makeup cosmetic composition according to the present invention, unlike conventional eye makeup cosmetics, can provide strong durability to both oil and moisture.

(2) Sensory evaluation of the cosmetic compositions of Examples 1-2 and Comparative Examples 1-4

Sensory evaluation was conducted on Examples 1 to 2 and Comparative Examples 1 to 4 prepared according to the composition of Table 1 above. 10 female consumers in their 20s and 30s were asked to compare the waterproof and smudge-proof effects of 20 products.

The waterproof effect was tested by applying each eyeliner of Examples 1 to 2 and Comparative Examples 1 to 4 on the back of the hand, drying for 10 minutes, then spraying water and rubbing with the hand to confirm the degree of erasure. In addition, for the smudge-proof effect, each eyeliner was applied between the knuckles, dried for 10 minutes, and then artificial sebum was applied, and then the fingers were bent and unfolded 50 times. As a result, it was tested by confirming the degree of spreading along the wrinkles between the knuckles. Each was given a score of 0 to 5, and the scores were averaged. The results are shown in Table 2 below.

Comparative Examples 1 to 4 showed excellent results in only one specific effect of waterproof or smudge proof, but the acrylate-based copolymers of Examples 1 to 2 obtained good results of 4 points or more for both waterproof and smudge proof.

2. Comparison of characteristics according to acrylate copolymer content ratio

(1) Preparation of cosmetic compositions of Example 3 and Comparative Examples 5 to 8

An eyeliner cosmetic composition comprising the composition (unit: weight%) of Table 3 below was prepared.

Two types of acrylate-based copolymers used in Examples 1 and 2, which received good sensory evaluation in 1 above, were used, and the cosmetic compositions of Example 3 and Comparative Examples 5-8 were prepared by varying their content ratio.

(2) Sensory evaluation of the cosmetic compositions of Example 3 and Comparative Examples 5 to 8

Sensory evaluation was conducted for Example 3 and Comparative Examples 5 to 8 prepared according to the composition of Table 3 above. Similarly, 10 female consumers in their 20s and 30s were targeted for 20 products, and the waterproof and smudge-proof effects of each composition were compared.

The waterproof and smudge-proof effects were tested in the same way as in 1. above, and the feeling of use was evaluated sensoryally based on spreadability during application. A score of 0 to 5 was given for each item, and the results of averaging the scores are shown in Table 4 below.

In the case of Example 3, it can be confirmed that all good results are shown in the feeling of use, the waterproof test, and the smudge proof test. In particular, when the copolymers of Acrylates/Ethylhexyl Acrylate Copolymer (Tg: -13) and Styrene/Acrylates/Ammonium Methacrylate Copolymer (Tg: 19) are mixed in the same ratio as in Example 3, than when each copolymer is used alone. It can be seen that both waterproof and smudge proof effects are improved.

1 is a photograph of the smudge proof test results of each Example 3 and Comparative Examples 5 to 8. As shown in the figure, the degree of spreading along the wrinkles between the fingers was evaluated, and it was confirmed that Example 3 was the most smudge-free.
