Water-based liquid cosmetic

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 pigment contains carbon black.

What is claimed is: 
     
         1 . A water-based liquid cosmetic comprising a mixture of: diethylhexyl sodium sulfosuccinate, an inorganic coloring pigment, a water-soluble dispersant, and a film-forming polymer emulsion,
 wherein a content of the 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,   wherein the inorganic coloring pigment comprises carbon black,   wherein the film-forming polymer emulsion is a polymer emulsion selected from the group consisting of an alkyl acrylate copolymer emulsion, an alkyl acrylate/styrene copolymer emulsion, an alkyl acrylate/vinyl acetate copolymer emulsion, an alkyl acrylate/diacetone acrylamide copolymer emulsion, and a urethane/acrylic composite resin emulsion, and   wherein the film-forming polymer emulsion, the diethylhexyl sodium sulfosuccinate, the inorganic coloring pigment, and the water-soluble dispersant are dissolved or dispersed in the cosmetic.   
     
     
         2 . The water-based liquid cosmetic according to  claim 1 , wherein the water-soluble dispersant comprises at least one water-soluble polymer selected from the group consisting of polyvinylpyrrolidone, polyvinyl alcohol, and an acrylic polymer. 
     
     
         3 . The water-based liquid cosmetic according to  claim 1 , wherein the water-soluble dispersant comprises at least one water-soluble polymer including an alkyl acrylate copolymer. 
     
     
         4 . The water-based liquid cosmetic according to  claim 1 , having a viscosity of 50 mPa·s or less at 25° C. 
     
     
         5 . The water-based liquid cosmetic according to  claim 1 , comprising no more than 0.1 mass % of a nonionic surfactant based on a total amount of the cosmetic. 
     
     
         6 . The water-based liquid cosmetic according to  claim 1 , wherein a content of the water-soluble dispersant is 0.5 to 5 mass % based on a total amount of the cosmetic. 
     
     
         7 . The water-based liquid cosmetic according to  claim 1 , wherein a content of the film-forming polymer emulsion is 1 to 20 mass % as a solid content concentration based on a total amount of the cosmetic. 
     
     
         8 . A water-based liquid cosmetic comprising a mixture of:
 0.01 to 1 mass % of diethylhexyl sodium sulfosuccinate;   3 to 20 mass % of an inorganic coloring pigment;   0.5 to 5 mass % of a water-soluble dispersant;   1 to 20 mass % of a film-forming polymer emulsion as a solid content concentration; and   40 to 80 mass % of water, based on a total amount of the cosmetic,   wherein the inorganic coloring pigment comprises carbon black,   wherein the film-forming polymer emulsion is a polymer emulsion selected from the group consisting of an alkyl acrylate copolymer emulsion, an alkyl acrylate/styrene copolymer emulsion, an alkyl acrylate/vinyl acetate copolymer emulsion, an alkyl acrylate/diacetone acrylamide copolymer emulsion, and a urethane/acrylic composite resin emulsion, and   wherein the film-forming polymer emulsion, the diethylhexyl sodium sulfosuccinate, the inorganic coloring pigment, and the water-soluble dispersant are dissolved or dispersed in the cosmetic.
