Problems solved by technology

[0010] However, even with the technologies described in the above-mentioned Patent Documents 1 to 4, it is still not possible to achieve both curling effect and volume at a high level.
For example, the cosmetics of the above-mentioned Patent Documents 1 to 3 in which waxes and film-forming agents have been studied are not sufficient in curling effect, and there is room for improvement in terms of non-caking and slipperiness.
In addition, waxes or film formers are mostly opaque substances, so the gloss of the makeup film will lose or look white, and it is difficult to obtain the luster that makes the eyelashes look glossy
In addition, as shown in the above-mentioned Patent Document 4, if a large amount of powder is blended in order to impart curl persistence, there is a tendency that caking is likely to occur and it is difficult to form a uniform cosmetic film.

Embodiment 1～14 and comparative example 1～7

[0106] The oil-in-water cosmetics for eyelashes having the compositions shown in Tables 1 to 5 were prepared by the following manufacturing methods, and the above-mentioned evaluations were performed. The results are shown in Tables 1-5 together.

[0107]

[0108] Components 1 to 13 were mixed, dissolved and homogenized by heating to 90° C., and this was used as an oil phase. Next, components 14 to 28, which were heated and dissolved at 90° C., were added to the oil phase and emulsified. After cooling the emulsion, component 29 was added and stirred. This was filled in a container to obtain an oil-in-water mascara.

Embodiment 15

[0132] (Example 15: mascara (containing fiber))

[0133]

[0134]

[0135] *The details of 1, 4, and 6 are the same as above.

[0136]

[0137] Components (1) to (10) were heated to about 90° C., mixed uniformly, and used as an oil phase. Next, components (11) to (16) heated to about 90° C. were added to the obtained oil phase and emulsified. After cooling the emulsion, component (17) was added and stirred. This was filled in a container to obtain an oil-in-water mascara (containing fibers).

[0138]

[0139] The obtained mascara (containing fibers) was evaluated in the same way as above. As a result, (a) the uniformity of the makeup film (no lumps), (b) adhesion, (c) gloss, (d) All the evaluation items of blackness, (e) curling effect, and (f) storage stability were evaluated as "⊚".

Embodiment 16

[0140] (Example 16: eyelash primer)

[0141]

[0142]

[0143] *The details of 2, 4, and 6 are the same as above.

[0144]

[0145] Components (1) to (11) were heated to about 90° C. and uniformly mixed to obtain an oil phase. Next, components (12) to (17) heated to about 90° C. were added to the obtained oil phase and emulsified. After cooling the emulsion, component (18) was added and stirred. Fill it into a container and you get a mascara primer.

[0146] The obtained mascara primer was evaluated in the same way as above. As a result, (a) uniformity of makeup film (no caking), (b) adhesion, (c) luster, (e) curling effect And (f) the evaluation of "⊚" among all the evaluation items of storage stability.

The oil-in-water emulsion cosmetic for eyelashes includes (A) a water-soluble film forming agent, (B) a water-soluble thickener, (C)a powder, and (D) a surfactant, in which the (B) includes at least one selected from the group consisting of a cellulose-based thickener and a polysaccharide-based thickener, the (C) includes carbon black, and the (D) includes a non-ionic surfactant having a HLB of 10 to 17 and a non-ionic surfactant having a HLB of less than 8.

Description

technical field [0001] The present invention relates to an oil-in-water cosmetic for eyelashes. Background technique [0002] Cosmetics for eyelashes such as mascara have a cosmetic effect such as making the eyelashes look thick and long to accentuate the eyes. In recent years, cosmetics for eyelashes of the oil-in-water emulsified type that can be easily removed with warm water have become increasingly popular. Furthermore, regarding the makeup effect, not only the thick feeling of the eyelashes but also the curling effect obtained by both the curling of the eyelashes and the curling retention force for maintaining the curling are emphasized. [0003] However, in the case of the oil-in-water type, since the main component is water, the drying speed is slow, and the eyelashes hang down due to their own weight before the makeup film is cured, so it is difficult to curl them. In addition, even if it is curled, there is a problem that since the outer phase is a water-based co...
