Filed: 1994-06-07
Abstract: PURPOSE:To provide a liquid coloring agent containing a black iron oxide colorant, a micro-encapsulated reducing substance and a solvent, exhibiting aging stability and effectively usable in cosmetics, etc. CONSTITUTION:This coloring agent is produced by incorporating a solvent solution (e.g. water) containing 2-55wt.% of a black iron oxide colorant with 0.1-10wt.% (based on the solvent solution of the black iron oxide colorant) of a reducing agent (e.g. ascorbic acid) sealed in microcapsules. In the case of using the black iron oxide as an aqueous dispersion, the liquid coloring agent is produced by incorporating the aqueous solution with 1,3-butylene glycol, etc., as a wetting agent in addition to a surfactant. The reducing substance is sealed in microcapsules by an arbitrary method such as interfacial polymerization. The discoloration of the liquid coloring agent is effectively prevented by using the sustainedrelease reducing substance.
