Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a liquid eye make-up cosmetic having good heat resistance and film-forming ability. More specifically, it causes resin agglomeration under a high temperature condition for a long period of time. It is an object of the present invention to provide a liquid eye makeup cosmetic having a film-forming ability, such as a mascara or an eyeliner.

[0002]

2. Description of the Related Art Conventionally, mascara which is applied to the eyelashes and eyeliner which is applied to the edges of the eyes are mainly composed of fatty acids such as stearic acid and myristic acid.
Triethanolamine and 2-amino-2-methyl-1-
An emulsion type having a film-forming ability prepared by emulsifying with water in which an alkali such as propanol is dissolved and then blending an acrylic resin emulsion is commercially available. Alternatively, an emulsion type having a film-forming ability prepared by emulsifying a nonionic activator such as a self-emulsifying glycerin fatty acid ester or a self-emulsifying propylene glycol fatty acid ester and then blending an acrylic resin emulsion is also commercially available.

However, when the amount of the acrylic resin emulsion is increased, the heat resistance of the liquid eye make-up cosmetic composition is remarkably lowered, and when it is kept at 50 ° C.,
The particles of the acrylic resin emulsion stick to each other and the liquid eye makeup cosmetic solidifies into a rubber. This phenomenon is more remarkable as the film forming temperature of the resin emulsion is lower and as the compounding amount of the resin emulsion is increased, which has been a problem in increasing the film forming ability.

[0004]

Means for Solving the Problems As a result of earnest studies in view of such problems, the present inventor has found that a liquid eye makeup cosmetic having a film-forming ability containing 10.0 to 60.0% by weight of an acrylic resin emulsion. In the case of 0.1 to 5.0% by weight of polyoxyethylene alkylphenyl ether having an addition mole number of ethylene oxide of 60 or more, the heat resistance of the cosmetic is remarkably improved,
It was found that the resin did not aggregate under a high temperature condition of ℃ for more than 1 year.

That is, according to the present invention, 10.0 to 60.0% by weight of an acrylic resin emulsion and 0.1 to 5.0% by weight of a polyoxyethylene alkylphenyl ether having an ethylene oxide addition mole number of 60 or more. %
A liquid eye make-up cosmetic characterized by being blended.

The structure of the present invention will be described in detail below. The liquid eye makeup cosmetic of the present invention is a liquid eye makeup cosmetic that forms an acrylic resin film after application, and has a makeup effect when used around the eyes such as mascara, eyeliner, and eye shadow. It is a cosmetic that gives

The acrylic resin emulsion used in the present invention is an aqueous emulsion of a copolymer containing at least one monomer selected from the group consisting of acrylic acid ester, methacrylic acid ester, acrylic acid and methacrylic acid. / Octyl acrylate / acrylic acid copolymer, methyl methacrylate / ethyl acrylate / acrylic acid copolymer, methyl methacrylate / octyl acrylate / methacrylic acid copolymer, methyl methacrylate / ethyl acrylate / methacrylic acid copolymer Polymer, methyl methacrylate / butyl acrylate / acrylic acid copolymer, methyl methacrylate / acrylic acid / styrene copolymer, octyl acrylate / acrylic acid / styrene copolymer, methyl methacrylate / acrylic acid / vinyl acetate Copolymer, octyl acrylate / acry Acid / vinyl acetate copolymer, methyl methacrylate / acrylamide / acrylic acid copolymer and emulsions such as methyl methacrylate / methacrylic acid amide / styrene / acrylic acid copolymer. The particle size of these resin emulsions is about 0.00
1 to 0.5 μm, and the resin solid content is about 30 to 60% by weight.

The amount of the acrylic resin emulsion blended in the liquid eye makeup cosmetic of the present invention is from 10.0 to
60.0% by weight is preferred. If it is less than 10.0% by weight, the film-forming ability is poor, and if it exceeds 60.0% by weight, the viscosity is too high for the purpose of mascara or eyeliner, and there is a problem in use.

In the polyoxyethylene alkylphenyl ether used in the present invention, the number of moles of ethylene oxide added is 60 or more, and preferably 80 to 80.
120. 60 moles of ethylene oxide added
When the amount is less than the above, the heat resistance of the liquid eye makeup cosmetic is lowered, and under the condition of 50 ° C., the particles of the acrylic resin emulsion stick to each other and the liquid eye makeup cosmetic solidifies into a rubber. Also, the number of added moles is 120
If it exceeds, it is possible to prevent the liquid eye makeup cosmetic from coagulating in a rubbery state, but the water resistance of the cosmetic gradually decreases, and there is a tendency for makeup to be lost due to sweat or the like.

The alkyl group of the polyoxyethylene alkylphenyl ether used in the present invention is not particularly limited, but an octyl group having 8 to 9 carbon atoms and a nonyl group are preferable.

The amount of polyoxyethylene alkylphenyl ether used in the present invention is 0.1 to 5.0% by weight. When it is less than 0.1% by weight, the cosmetic has no anticoagulant effect, and when it exceeds 5.0% by weight, the cosmetic has anticoagulant effect, but the liquid eye makeup cosmetic has extremely poor water resistance.

Of course, after the polyoxyethylene alkylphenyl ether used in the present invention has been blended in advance in the process of producing the acrylic resin emulsion,
It is also effective in improving heat resistance when used in liquid eye makeup cosmetics.

In other nonionic surfactants such as polyoxyethylene linear alkyl ether, polyoxyethylene sorbitan fatty acid ester and polyoxyethylene glycerin fatty acid ester, the number of carbon atoms in the alkyl group, the type of fatty acid, and the polyoxyethylene Even if the number of moles of ethylene added is changed, the heat resistance is not improved.

In the liquid eye makeup cosmetic of the present invention, in addition to the above-mentioned essential components, other surfactants, waxes, oils, pigments or dyes, preservatives, antioxidants, fragrances and the like are generally added to cosmetics. The components described above can be appropriately blended within a range that does not impair the stability of the acrylic resin emulsion.

[0015]

The effects of the present invention will be described in more detail with reference to the following examples. The blending amount shown below is% by weight.

(Preparation method of mascara) With the following composition,
The mascara of Examples 1-6 and Comparative Examples 1-4 were prepared. As a preparation method, polyvinylpyrrolidone, propylene glycol, triethanolamine, polyoxyethylene alkylphenyl ether, and a preservative were dissolved in pure water at 80 ° C., and then the pigment was dispersed to obtain an aqueous phase. On the other hand, an oil phase obtained by dissolving stearic acid and beeswax at 80 ° C was added to the aqueous phase and emulsified with a homomixer. Then, the acrylic resin emulsion was gradually added, and the mixture was further stirred with a homomixer and then cooled to room temperature. Here, all acrylic resin emulsions used had a resin solid content of 46% by weight.

(Heat resistance test of mascara) After placing the prepared mascara in a closed glass container, 40 ° C, 45 ° C, 50
After 1 week, 1 month, 3 months, 6 months, and 1 year after leaving it in each of the thermostatic chambers at ℃, check the mascara for coagulation. Those that had solidified were evaluated by "x".

(Practical Property Test of Mascara) The prepared mascara was subjected to the following practical property test. In the practical property test, the mascara was applied to 20 female panelists on the eyelashes, and the cosmetic effect was evaluated by 5 grades (5: good, 4: good, 3: normal, 2: bad, 1: bad). Then
The average value was taken.

[0032]

[Table 2]

From Table 1, it is clear that Examples 1 to 6 are superior in heat resistance to Comparative Examples 1, 2 and 4. Although Comparative Example 3 is excellent in heat resistance, it can be seen from Table 2 that the effect of water resistance is extremely low as compared with Examples 1 to 6, and therefore the makeup retention is poor. On the other hand, the fact that the water resistance of Example 6 tends to be lower than that of the other Examples is due to the reason described above.
