(Industrial Application Field) The present invention relates to a liquid cosmetic having excellent line drawing and application performance, and in particular to a liquid cosmetic for use in pen-shaped cosmetics that has good discharge from the pen tip and less clogging of the pen tip. It is. (Prior art and its problems) Conventional cosmetics such as eyeliners, eyebrows, eye shadows, and mascaras include types in which highly viscous liquid cosmetics are contained in a cosmetic container and brushes are soaked with the liquid cosmetics. There are types that apply powdered cosmetics with an applicator such as a brush or sponge, and pencil-shaped types that have solid cosmetics as a core.Types that use high viscosity liquid cosmetics have a continuation of the liquid. It was difficult to apply the liquid to the brush many times during use, and the application feeling was also poor. The same goes for the powder type, and the pencil type also has the risk of damaging the eyes. (Means for Solving the Problems) Therefore, the inventors of the present invention have conducted extensive research based on the viewpoint that the above-mentioned problems can be solved if liquid cosmetics can be made to have a low viscosity and can be incorporated into pen-shaped cosmetics. As a result, we obtained the following knowledge. In order to incorporate liquid cosmetics into a pen-shaped cosmetic tool and guide the liquid to the pen tip using capillary force,
It is necessary to set the viscosity of the liquid to 1.5 to 50 centipoise (hereinafter abbreviated as cps). Bleeding is a new problem that occurs when liquid cosmetics are made to have a low viscosity, and it is necessary to solve this problem while also satisfying the fixability, flexibility, and water resistance of the applied surface for practical purposes. Furthermore, since it is a pen-shaped cosmetic tool, it is necessary to consider discharge from the pen tip and prevention of clogging at the pen tip. In view of the above-mentioned points, the present invention was finally completed as a result of various studies on pigments as colorants and binders that particularly affect drawing characteristics. That is, the present invention provides a pigment having a particle size of 1 μm or less; a betaine type amphoteric methacrylic acid ester polymer represented by the following general formula (); propylene glycol;
The gist of the invention is a liquid cosmetic comprising at least glycerin and polyethylene glycol, either alone or as a mixture. <General formula> (In the formula, n+m=400-450 R= C1 - C18 alkyl group) (Structure) The present invention will be described in detail below. The coloring agent for the liquid cosmetic of the present invention has a particle size of
It is necessary to use pigments with a diameter of 1μ or less. Particularly when using a porous material such as urethane as a pen tip, if the particle size of the pigment is large, the pen tip tends to become clogged, and conversely, if the pores (capillary diameter) in the pen tip are made large, the capillary force Functionality deteriorates and liquid leakage and liquid swallowing phenomena occur. Then,
The pores in the pen tip are naturally limited, and as a result of repeated experiments by crushing and dispersing the pigment, the inventors found that in order for the pigment to pass smoothly without clogging the pores in the pen tip, the particle size of the pigment must be adjusted. It was found that it is necessary to reduce the value to 1μ or less. The particle size of pigments varies depending on the type of pigment and manufacturing method, but since particles smaller than primary particles cannot be produced through post-processing such as crushing and dispersion, the primary particles of the pigments used often contain particles of 1μ or less. However, most pigments are in a secondary or tertiary agglomerated state, and it is necessary to crush and disperse these into a primary particle state and crush all particles to less than 1μ, which is difficult to use. There are differences depending on the machine used, and it is virtually impossible to crush everything down to primary particles.
Since this is difficult, particles larger than 1μ are removed by post-processing, such as ultracentrifugation. Further, pigments whose primary particles are all 1μ or more cannot be used in the present invention, but if it is a mixture of primary particles of 1μ or more and 1μ or less, the pigments of 1μ or more will be removed through post-processing to make a liquid cosmetic. be able to. In addition, even if the pigment has been treated to a size of 1μ or less, the pigment particles will attract each other due to the Van der Waals force, causing aggregation and increasing the size of the particles.This can be prevented by the dispersant effect, and the pigment particles can be According to the law, sedimentation occurs over time, so this also needs to be prevented. In the present invention, the second method is to use a betaine type amphoteric methacrylic acid ester polymer represented by the general formula (), which has a dispersant effect and an anti-sedimentation effect, as these inhibitors. Features. This is the result of examining various water-soluble polymers and latexes for use in cosmetics, taking into account their toxicity.
Liquid cosmetics can be made with low viscosity (1.5 to 50 cps),
It has the effect of preventing agglomeration and sedimentation of pigment particles, and also has little bleeding, practical fixability, flexibility,
We have discovered a betaine type amphoteric methacrylate ester polymer represented by the general formula () having abrasion resistance and water resistance. Furthermore, in the present invention, propylene glycol, glycerin, polyethylene glycol alone or a mixture thereof is added in an amount of 2 to 30% based on the total amount of the liquid cosmetic.
Use % by weight. In cosmetics, the use of water-soluble organic solvents as liquid moisturizers is prohibited due to toxicity, especially skin absorption. Among these, safe liquid moisturizers include propylene glycol, glycerin, and polyethylene glycol alone or in combination. These liquid moisturizers also act as a solubilizer for the betaine type amphoteric methacrylic acid ester polymer represented by the general formula (). Since the liquid cosmetic of the present invention uses a pen-shaped cosmetic tool, dryness particularly at the pen tip and freeze aggregation at low temperatures are problematic. Regarding freeze aggregation, from a practical point of view, it is sufficient if the pigment returns to its original dispersed state when the temperature returns to room temperature, but it is preferable that the freezing temperature be as low as possible. By adding 2% by weight or more of a liquid humectant, freezing can be prevented at temperatures above 0° C., which is a practical temperature. Furthermore, as mentioned above, since the liquid cosmetic of the present invention is used in a pen-type cosmetic tool, the pen tip is exposed when the cap of the cosmetic tool is removed, so it is difficult to forget to put the cap on. It is more preferable to prevent the liquid from drying at the pen tip and making it impossible to write even if misused, so in the present invention, a liquid humectant is added for this purpose as well. In this case, the greater the amount added, the greater the effect, but if the amount is 30% by weight or more, problems arise in that the liquid viscosity becomes too high and the drying of the coated surface becomes too slow. From the above points, it is preferable to use 2 to 30% by weight of the liquid humectant in the present invention. In addition to the above-mentioned essential ingredients, in the present invention, as necessary, urea and/or its derivatives are used as drying preventive agents and moisturizers at the pen tip, various surfactants are used as dispersants or penetrants, and various preservatives. fungicide,
Furthermore, various water-soluble polymers may be added as appropriate for the purpose of adjusting liquid viscosity or as an aid for preventing pigment sedimentation. (Function) Since the betaine type acrylic resin represented by the above general formula used in the present invention is a betaine type amphoteric resin, it has ○+ and ○− in close positions, creating an apparent network structure. Since there is no oxidation agent, and because the molecular weight is relatively low and the solubility in water is good, the viscosity does not increase much, and the viscosity of the liquid cosmetic can be made low. In addition, when betaine-type amphoteric resin is adsorbed around pigments, both ○+ and ○- are formed, so even when pigment particles approach each other, electrostatic repulsion works and prevents aggregation more strongly than with other resins. Furthermore, the presence of both ○+ and ○- ions makes the affinity with water of the ○+ and ○- ions of the betaine type amphoteric resin adsorbed on the pigment stronger, and it is also possible to prevent the pigment from settling. . (Examples) The present invention will be explained in more detail below using examples. In Examples and Comparative Examples, "parts" simply indicate "parts by weight."

This entire amount is passed through a three-roll mill five times to crush and disperse the pigment to create a pigment paste. or,
On the other hand, the remaining ingredients were sequentially added to the remaining 38.5 parts of purified water while stirring to make a homogeneous aqueous solution, and then
After adding the entire amount of the pigment paste ground and dispersed using this roll mill and stirring at high speed using a homomixer for 1 hour, the pH was confirmed to be 7.5. In this state, I checked the particle state of the pigment with a grind gauge, and found that
Since some 1μ to 5μ remained, the entire amount was centrifuged at 5000 rpm for 30 minutes in a centrifuge with a rotation radius of 15cm, and the liquid was removed by decantation to obtain a black eyeliner solution. When I checked the particle size of this eyeliner liquid again using a grind gauge, all particles were 0.8μ or less. The viscosity of this eyeliner liquid at 25°C was measured to be 4.0 cps using a B-type rotational viscometer at 60 rpm. After the black eyeliner liquid of this example was heat sterilized, it was filled into an eyeliner equipped with a prototype urethane nib having continuous pores that had been sterilized with ethylene oxide gas to prepare a test sample.
