Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has excellent resistance to drying when applied to a cosmetic-containing type applicator.
In addition, the present invention relates to a liquid cosmetic which is excellent in the dryness of application marks.

[0002]

2. Description of the Related Art Conventionally, in liquid cosmetics, propylene glycol, 1,3-butylene glycol, glycerin and the like have been used as hygroscopic water-soluble organic solvents.

[0003]

However, when propylene glycol or 1,3-butylene glycol is used, its moisturizing property is insufficient, and when the cap of the applicator is removed and left to stand, application is not possible. There is a problem that the portion is easily dried and becomes unusable, and when the coated portion is dried, it is difficult to restore even if the cap is put on.

Further, when glycerin is used, the moisturizing property is excellent, but the dryness of the application mark when applied to the skin is poor, and there is a problem in that the transfer of the application mark occurs in, for example, an eyeliner. Further, when the coated portion is dried, even if a cap is used to restore the ink, the viscosity of glycerin is too high, which impedes the flow of the ink and rather delays the restoration.

[0005]

The present invention is characterized by comprising at least a colorant, water, and one or more selected from pentaerythritol, trimethylolethane, and trimethylolpropane. The main point is liquid cosmetics.

The present invention will be described in detail below. As the colorant, any of water-soluble dyes and pigments can be used as long as they can be used in cosmetics. Moreover, each may be used alone or in combination of two or more. The usage is
It is preferably 1 to 20% by weight with respect to the entire liquid cosmetic.

Water is used as the main solvent. Pentaerythritol, trimethylolethane or trimethylolpropane is used as a solvent and a moisturizer. The amount used is preferably 0.01 to 15% by weight. In particular, pentaerythritol dissolves only about 5.5% by weight in water, and it is not preferable to add an excessive amount.

In addition to the above-mentioned components, propylene glycol may be used as a drying control agent for the coating part and the coating trace, if necessary.
Water-soluble organic solvents that have been conventionally used, such as toluene, 1,3-butylene glycol and glycerin, can be used together.
Further, urea as a moisturizing aid, a surfactant as a penetrating agent or a dispersant, a water resistance of a coating mark, an improvement in fixing property or a resin and an antiseptic / antifungal agent as a dispersant, a water-soluble polymer as a viscosity modifier, and a pH. As an adjusting agent, an alkalizing agent or the like can be appropriately selected and used as an additive.

When a dye is used as a coloring material, the present liquid cosmetic composition is prepared by agitating and mixing each component with a conventionally known stirrer such as a homomixer or a propeller stirrer to uniformly dissolve the components. When a pigment is used as a coloring material, the pigment is dispersed by a conventionally known disperser, for example, a ball mill, a roll mill, a sand mill or the like, and the mixture is stirred and mixed with other components to prepare a cosmetic. It can be obtained by a method such as.

Function: Pentaerythritol and trimethylol of the present invention
Since ruethane or trimethylolpropane has many hydroxyl groups in the molecule, propylene glycol and 1,
It can retain more water than 3-butylene glycol. This suppresses the evaporation of water at the pen tip and makes it more difficult for the coated part to dry than propylene glycol or 1,3-butylene glycol. Also pentaerythrit
Since trimethylolethane or trimethylolpropane is a crystalline solid at room temperature, the coating trace can be dried only by evaporation of water, and pentaerythritol and trimethylol by evaporation of water. The transfer of the coating mark can be prevented by solidifying ruethane or trimethylolpropane. Thus, it is presumed that excellent performance as a liquid cosmetic composition can be obtained by using pentaerythritol, trimethylolethane or trimethylolpropane.
