Description

The present invention relates to eyebrow cosmetics, and more particularly, to eyebrow coat cosmetics useful for preventing eyebrows from breaking apart.

Eye makeup plays an important role in forming a person's image in the person's appearance. Above all, the shape of the eyebrows is one of the factors that have a great influence. For this reason, eyebrows have been widely made up since ancient times, such as shaving the eyebrows and drawing them artificially. Even in modern times, it is widely practiced to draw eyebrows with eyebrow mascara after shaving the eyebrows or removing the eyebrows. The eyebrow mascara and the like used for such eyebrow make-up use various waxes in a high blend for the purpose of increasing the viscosity and stabilizing the system. In particular, such a system has a drawback that the makeup is easily lost due to weak adhesion to the skin. For this reason, portability was improved, and it was necessary to remake regularly. It has been desired to develop a means for improving the longevity of such eyebrows.

On the other hand, it has been developed for the purpose of preventing color transfer to cups, cigarettes, etc. in cosmetics such as lipsticks that cover makeup cosmetics from above with specific cosmetics to improve their makeup. There has been no known keep coat cosmetic for the purpose of preventing makeup collapse. In particular, there was no idea of cosmetics for eyebrow coats useful for preventing physical friction such as hair touching eyebrows, and makeup collapse caused by sweat, sebum, etc., and their existence was not known at all.

The preferable content thereof is 1 to 10% by weight, and more preferably 2 to 8% by weight. This is because if the amount is too small, the plasticity and antimicrobial effects may be impaired, and if the amount is too large, the formation of the coating itself may be impaired. When such a polyhydric alcohol is used, it is preferable to use paraben and / or phenoxyethanol because the antimicrobial properties are further improved. The preferable content of paraben and / or phenoxyethanol is 0.1 to 1% by weight based on the total amount of the cosmetic.

The eyebrow cosmetic of the present invention can be produced by treating the essential components, optional components, and preferred components according to a conventional method.

By using the eyebrow cosmetic composition of the present invention, for example, the coating formed by applying the eyebrows and then applying the eyebrows has an effect of preventing the eyebrows from being broken by sweat or sebum.

In addition, by using the eyebrow cosmetic of the present invention, a cosmetic having a high wax content and therefore low adhesion to the skin can be adhered and fixed. This can also prevent makeup collapse.

The eyebrow dosage form to which the eyebrow cosmetic of the present invention is applied is not particularly limited, and can be applied to commonly known dosage forms such as an emulsification type, an oil gel type, and a solvent dispersion type. As an indication of the content of the wax, those containing 10 to 70% by weight of the total amount of eyebrow can be preferably exemplified. Among these, it is particularly preferable to use as an oil gel type eyebrow cosmetic material in which the problem of makeup collapse is particularly significant. In other words, by applying the eyebrow cosmetic film of the present invention over the eyebrow with a high amount of wax, the eyebrow can be fixed, and makeup collapse due to sebum or sweat can be prevented.

Hereinafter, the present invention will be described in detail by way of examples, comparative examples, and test examples, but the present invention is not limited to these examples.

<Example 1 and Comparative Example 1>
According to the formulation shown below, the eyebrow cosmetic of the present invention was produced. (Table 1) Moreover, eyebrow mascara was produced as an example of the eyebrow to apply to the eyebrows. (Table 2) In addition, a mixture ratio is a weight part.

<Test Example 1>
The long-lasting effect of the eyebrow cosmetic of the present invention was confirmed by a sauna test in cooperation with 10 panelists. That is, the eyebrow cosmetic material 1 of the present invention was applied to the right eyebrow part drawn with an eyebrow mascara produced as an example of eyebrow ink. (Example 1) Further, as a control, the left eyebrow was only drawn with the same eyebrow mascara. (Comparative Example 1) After that, the panelist was allowed to enter the sauna for 10 minutes, and the professional panelist determined that she had 10 minutes after leaving the room according to the following evaluation criteria.

〔Evaluation criteria〕
5 points: Very good.
(No blur of the eyebrow line is observed.)
4 points: Good.
(The blur of the eyebrow line is hardly observed.)
3 points: Neither can be said.
(Although there is a slight blur on the eyebrow line, there is little blurring and makeup break-up is not noticeable.)
2 points: Somewhat bad.
(The eyebrow line has a faint blur and slight blurring. If you look at it in a bright place, you can see the makeup collapse.)
1 point: Very bad.
(Even if it is clearly dark, you can see that the eyebrows line is broken.)

As is apparent from the results in Table 3, it was found that the eyebrow cosmetic 1 of the present invention is a cosmetic having an excellent function of improving the makeup of the eyebrows when used from above the eyebrows.

<Example 2 and Comparative Example 2>
The eyebrow cosmetic 2 was prepared in the same manner as in Example 1, and the same test using the above eyebrow mascara was conducted to evaluate the cosmetic durability. That is, with regard to the eyebrow cosmetic 2 for the eyebrow coat in which the alkyl acrylate copolymer emulsion of Table 1 is replaced with the same pure alkyl acrylate / styrene copolymer emulsion, the eyebrow make-up is the same as in Test Example 1. The expert panel judged on the evaluation criteria.

As is apparent from the results in Table 4, the eyebrow cosmetic 2 of the present invention is slightly inferior to the eyebrow cosmetic 1 described above. It turned out to be cosmetics.

That is, the eyebrow cosmetic of the present invention includes a gel composed of an anionic polymer and a vinyl acetate / vinyl pyrrolidone copolymer, and a vinyl pyrrolidone / N, N-dimethylaminoethyl methacrylate that is a cationic polymer as a film forming agent. An acid copolymer diethyl sulfate can be preferably used. Among these, as the anionic polymer, an alkyl acrylate copolymer emulsion is most preferable.

<Examples 3-5 and Comparative Examples 3-5>
By changing 1,3-butylene glycol of Example 1 to other polyhydric alcohols, a specialized panelist determined that the eyebrows had a makeup with the same evaluation criteria as in Test Example 1. That is, one replaced with 1,2-pentanediol (Example 3), one replaced with isoprene glycol (Example 4), and one replaced with glycerin (Example 5).

As is apparent from the results of Table 5, in the eyebrow cosmetic of the present invention, the polyhydric alcohol is, in particular, one or two selected from 1,3-butylene glycol, 1,2-pentanediol and isoprene glycol. It turns out that more than a seed can be used preferably.

In the present invention, the eyebrow cosmetics can be coated not only with eyebrows and can improve makeup retention, but also contain physiologically active ingredients, so that they are widely used as eyebrow cosmetics for various purposes. Application can be expected.
