Description

[Technical Field]

[0001] This invention relates to a cosmetic product for eyelashes. [Background technology]

[0002] Mascara and other eyelash cosmetics utilize oil-dispersion (non-aqueous dispersion) formulations or W / O (water-in-oil) formulations containing various oil-soluble film-forming agents to enhance makeup longevity, such as water resistance and curling power. However, these products cannot be removed with ordinary facial cleansers or cleansing foams, requiring the use of oil-based cleansers or specialized makeup removers, which can damage eyelashes or irritate the skin, making cleansing difficult. To improve the cleansing power of such mascaras, O / W (oil-in-water) formulations using water-soluble or water-dispersion film-forming agents are also used, but these reduce makeup longevity, such as curling power, compared to oil-dispersion or W / O formulations containing oil-soluble film-forming agents.

[0003] As a means of solving this problem, for example, cosmetics using non-aqueous polymer dispersions made from various copolymers have been proposed. However, for example, the cosmetic in Patent Document 1 uses a non-aqueous polymer dispersion, but it is difficult to remove, and its removal requires a facial cleanser such as a point makeup remover specifically for the eye area. Similarly, the oily cosmetic in Patent Document 2 also uses a non-aqueous polymer dispersion, but it is not removed by normal water washing and requires a separate facial cleanser such as an oil.

The evaluation of ease of removal (removability with hot water) and stability was performed using the same procedure as described above, while the evaluation of oil cleansing performance, water resistance, and oil resistance was performed using the following procedure.

[0094] Evaluation of the cleansing performance of oil cleansers Each prepared eyelash cosmetic for the examples and comparative examples was uniformly applied to a microscope slide in a 0.3g portion. A 0.05g drop of commercially available facial cleansing oil was then added and left to stand for 1 minute. After that, the slides were immersed in 40°C water for 3 minutes, wiped with a tissue, and the degree of removal was checked. The cleansing performance of the oil cleanser was then evaluated according to the following evaluation criteria. <Evaluation Criteria> A: Removal rate is 80% to 100% B: Removal rate 50%~80% C: Removal rate 30%~50% D: Removal rate 10%~30% E: Does not fall

A drop of water was then applied to filter paper (10 cm). 2(For water resistance evaluation), and filter paper with artificial sebum drops (10cm 2 A sample (for oil resistance evaluation) was prepared, and the application area of ​​the eyelash cosmetic was tapped onto the filter paper 30 times each using a tapping test machine (N=3). The degree of transfer to the filter paper after tapping was checked for bleeding, and the water resistance and oil resistance were evaluated according to the following evaluation criteria. <Evaluation Criteria> A: There is very little transfer to the filter paper, so there is no concern about bleeding. B: There is some transfer to the filter paper, but there is almost no concern about bleeding. C: There is a possibility of transfer to the filter paper, and there is a slight concern about bleeding.

[0102] The eyelash cosmetic prepared as described above was evaluated for ease of removal (removable with hot water), stability, cleansing ability with oil cleansing, water resistance, oil resistance, and makeup longevity. The evaluation of ease of removal (removable with hot water), stability, cleansing ability with oil cleansing, water resistance, and oil resistance was performed using the same procedure as described above, and the evaluation of makeup longevity was performed using the following procedure.

[0103] Makeup longevity rating Each prepared eyelash cosmetic was uniformly applied to the coating surface of a tapping test machine (water and oil resistance confirmation test) and allowed to dry to form a film. A filter paper (10 cm) with no drops of liquid was then used. 2 A tapping test machine was used to tap each of the areas on the filter paper where the eyelash cosmetic was applied 30 times (N=3). The degree of transfer to the filter paper after tapping was used to check for bleeding, and the durability of the cosmetic was evaluated according to the following evaluation criteria. <Evaluation Criteria> A: There is absolutely no transfer to the filter paper, so you can expect excellent makeup longevity. B: There is very little transfer to the filter paper, so it can be expected to last a long time. C: There is some transfer to the filter paper, but there is little concern about the makeup staying put. D: There is transfer to the filter paper, raising concerns about the durability of the cosmetic product.
