Abstract

A water-based liquid cosmetic containing diethylhexyl sodium sulfosuccinate, an inorganic coloring pigment, a water-soluble dispersant, and a film-forming polymer emulsion, wherein a content of diethylhexyl sodium sulfosuccinate is 0.01 to 1 mass % and a content of the inorganic coloring pigment is 3 to 20 mass %, based on a total amount of the cosmetic, and wherein the inorganic coloring pigmentcontains carbon black.

Description

technical field [0001] The invention relates to a water-based liquid cosmetic. Background technique [0002] As water-based liquid cosmetics used in cosmetics, products obtained by dissolving or dispersing colorants in water or aqueous organic solvents are known. For cosmetics such as eyeliner or eyebrow pencil, inorganic coloring pigments are often used as colorants. This is due to the tendency, especially in eyeliners, to draw intensely colored lines to enhance the makeup of the eyes. However, inorganic coloring pigments have a large specific gravity and are prone to aggregation and sedimentation, so they tend to be insufficiently dispersed in water-based liquid cosmetics and tend to cause color unevenness in drawing lines. [0003] In addition, water-based cosmetics tend to be inferior in water resistance and friction resistance of cosmetic films compared with oily cosmetics or water-in-oil emulsion cosmetics. Therefore, it is difficult to improve the make-up retention...
