Description

Technical Field

[0001] The present invention relates to an oily transparent mascara base makeup. More specifically, it relates to an oily transparent mascara base makeup that maintains colorless transparency without turning white after application and has excellent curling power and curling retention power.

Background Art

[0002] Mascara base makeup is used to enhance curling retention, volume, and long effect, improve the color development and adhesion of mascara, and prevent the collapse, bleeding, and smudging of mascara. Therefore, mascara base makeup is required to have good adhesion, excellent curling power, and curling retention power. In order to impart curling power and curling retention power to eyelashes, an oily mascara base makeup containing a large amount of wax is generally used. However, there is a problem that it turns white after application when wax is blended. In addition, an oily mascara base makeup containing a high concentration of wax has a feeling of snagging when applying mascara, making it difficult to apply mascara smoothly.

[0003] In recent years, from the perspective of the compatibility of colored mascara, which is in increasing demand, and natural makeup, a mascara base makeup having colorless transparency has been desired. In addition, since mascara can be easily removed with water while the mascara is applied, a colorless transparent water-soluble type of mascara base makeup that does not contain wax is commercially available. However, the water-soluble type of mascara base makeup has weak curling power and curling retention power, and there is a problem that the mascara base makeup collapses due to sweat or tears.

[0004] Regarding oil-based mascara primers, for example, Patent Documents 1 and 2 describe them as follows. Patent Document 1 describes a mascara primer characterized by containing component (a) an oil-soluble resin, component (b) an aqueous component, and component (c) anhydrous silicic acid. However, because it contains component (c) anhydrous silicic acid, it is not colorless and transparent. All of the oil-based gel-type mascara primers in Examples 1 to 9 and Comparative Examples 1 to 3 described in Patent Document 1 are semi-transparent. Thus, the mascara primer described in Patent Document 1 does not fall under the category of a colorless and transparent oil-based transparent mascara primer that is the target of the present invention.

[0005] Patent Document 2 describes a mascara primer cosmetic characterized by containing (a) 0.1 to 4.0% by mass of black colored nylon fibers, (b) 0.03 to 6% by mass of a siliconeized polysaccharide compound, (c) 3 to 30% by mass of wax, and (d) 3 to 30% by mass of dextrin fatty acid ester. However, the mascara primer cosmetic of Patent Document 2 contains (a) black colored nylon fibers to suppress the drawback of turning white after application due to the inclusion of (c) wax, and is therefore not colorless and transparent. Thus, the mascara primer cosmetic of Patent Document 2 does not fall under the category of a colorless, transparent oil-based transparent mascara primer cosmetic targeted by the present invention.

The average transmittance of the cover slip (uncoated) was set to 100, and this was used as the transmittance of the oil-based transparent mascara base cosmetic.

[0036] Example 1 and Comparative Examples 1-6 Preparation of oil-based transparent mascara base cosmetic Following conventional methods, oil-based transparent mascara base cosmetics for Example 1 and Comparative Examples 1-6 were prepared by mixing the components in the amounts listed in Table 1. The results of the evaluation tests conducted on the prepared oil-based transparent mascara base cosmetics are shown in Table 1.

[0037] [Table 1]

[0038] The oil-based transparent mascara base cosmetics of Comparative Examples 1 to 6 are oil-based transparent mascara base cosmetics that do not contain one or two of the (A) sugar fatty acid ester-based oil gelling agent, (B) amino acid-based oil gelling agent, and (C) polymer-type oil gelling agent in the present invention. Specifically, Comparative Example 1 does not contain component (A), Comparative Example 2 does not contain components (A) and (B), Comparative Example 3 does not contain components (A) and (C), Comparative Example 4 does not contain component (B), Comparative Example 5 does not contain component (C), and Comparative Example 6 does not contain components (B) and (C). As shown in Table 1, the oil-based transparent mascara base cosmetic of Example 1 performed better in the evaluation test than any of the oil-based transparent mascara base cosmetics of Comparative Examples 1 to 6. Comparative Examples 1-3 involved a roller treatment to homogenize mascara primers. However, the gelling agent did not homogenize within the mascara primer, and only the gelling agent did not enter the roller, making it unusable as a mascara primer. From the above, it can be seen that in the present invention, (A) sugar fatty acid ester-based oil gelling agent, (B) amino acid-based oil gelling agent, and (C) polymer-type oil gelling agent are necessary components for maintaining colorless transparency without turning white after application, for avoiding a catching sensation when applying mascara, and for having excellent curling power and curl-holding power.

[0039] Example 2 and 5 and Reference Examples 3 and 4 Preparation of oil-based transparent mascara base cosmetic By mixing the components in the amounts listed in Table 2 according to the conventional method, Example 2 and 5 and Reference Examples 3 and 4 An oil-based transparent mascara base cosmetic was prepared. The results of the evaluation tests conducted on the prepared oil-based transparent mascara base cosmetic are shown in Table 2.

[0040] [Table 2]

[0041] Example 2 and 5 and Reference Examples 3 and 4 The oil-based transparent mascara base cosmetic was similar to or better than the oil-based transparent mascara base cosmetic of Example 1.

[0042] Examples 7 and 8 and Reference Examples 6 and 9-11 Preparation of oil-based transparent mascara base cosmetic By mixing the components in the amounts listed in Table 3 according to the conventional method, the Examples 7 and 8 and Reference Examples 6 and 9-11 An oil-based transparent mascara base cosmetic was prepared. The results of the evaluation tests conducted on the prepared oil-based transparent mascara base cosmetic are shown in Table 3.

[0043] [Table 3]

[0044] Examples 7 and 8 and Reference Examples 6 and 9-11 The oil-based transparent mascara base cosmetic is primarily a modified version with altered content of component (C). As shown in Table 3, the evaluation test results were satisfactory when the content of component (C) was 0.5 to 2% by mass. More preferably, the content of component (C) was 0.7% by mass or more.

[0045] Examples 12-16 Preparation of oil-based transparent mascara base cosmetic Following conventional methods, the oil-based transparent mascara base cosmetics of Examples 12-16 were prepared by mixing the components in the amounts listed in Table 4. The results of the evaluation tests conducted on the prepared oil-based transparent mascara base cosmetics are shown in Table 4.

[0046] [Table 4]

[0047] The oil-based transparent mascara base cosmetics of Examples 12-16 are mainly variations in component (D) and its content. As shown in Table 4, all of Examples 12 to 16 showed excellent results in the evaluation tests. It was found that a combination of trimethylsiloxysilicate, polymethylsilsesquioxane, and (vinylpyrrolidone / eicosene) copolymer as component (D), as in Examples 12 and 13, was more preferable.

[0048] Example 12 and Comparative Examples 7 and 8 Comparison of oil-based white mascara primer containing wax and water-based clear mascara primer. According to conventional methods, the oil-based white mascara base cosmetic containing wax of Comparative Example 7 and the aqueous transparent mascara base cosmetic of Comparative Example 8 were prepared by mixing the components in the quantities shown below.

[0049] [Table 5]

[0050] The results of the evaluation tests conducted on the mascara base cosmetics of Example 12 and Comparative Examples 7 and 8 are shown in Table 6.

[0051] [Table 6]

[0052] The oil-based white mascara base cosmetic containing wax in Comparative Example 7 had significantly lower transmittance and was inferior in smoothness and curl-holding ability compared to the oil-based transparent mascara base cosmetic in Example 12 of the present invention. The aqueous transparent mascara base cosmetic of Comparative Example 8 had higher transmittance compared to the oil-based transparent mascara base cosmetic of Example 12 of the present invention, but it was inferior in terms of film-forming (firmness), curling power, and curl-holding power, as well as adhesion.

[0053] The embodiments and examples disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are included.
