Provided is a liquid cosmetic which can suitably be used for a liquid cosmetic applicator using a brush or a pen feed as an applying means and which has good water resistance and is excellent in an adhesive property to the skin. The liquid cosmetic comprises at least carbon black, water, 0.5 to 5% by mass of a dispersant comprising a film-formable resin, 2 to 15% by mass (in terms of a solid content) of a film-forming agent and 0.5% by mass or less of a surfactant, and a viscosity thereof measured at a temperature of 25° C. and a shear rate of 3.83 S−1 by means of an ELD type viscometer falls in a range of 2 to 8 mPa·s. |

1. A liquid cosmetic for an eyeliner or for applying to an eyebrow stored in a liquid cosmetic applicator using a brush or a pen feed as an applying means, wherein the liquid cosmetic comprises at least carbon black, water, 0.5 to 5% by mass of a dispersant comprising a soluble copolymer which is a copolymer of vinylpyrrolidone-vinyl acetate, a copolymer of vinylpyrrolidone-dimethylaminopropylacrylamide, or a copolymer of octylacrylamide-acrylic ester, 2 to 15% by mass, in terms of a solid content, of a film-forming agent of an emulsion of a water-insoluble copolymer made from two or more components selected from acrylic acid, methacrylic acid, alkyl (C1 to C4 and C8) esters of acrylic acid, or alkyl (C1 to C4 and C8) esters of methacrylic acid, and 0.5% by mass or less of a surfactant, and a viscosity of the liquid cosmetic measured at a temperature of 25° C. and a shear rate of 3.83 S−1 by means of an ELD type viscometer using a cone rotor falls in a range of 2 to 6 mPa·s. |
