An O/W/O type multiple emulsion in which an O/W type emulsion is dispersed in the outer phase oil wherein the O/W type emulsion in the inner phase contains water, an oil based ingredient, a surfactant and an amphiphilic substance chosen from those which can form a gel at ordinal temperature or higher in an amphiphilic substance-surfactant-oil-water system or N-long chain acyl acidic amino acid monosalt and an amphiphilic substance chosen from those which can form a gel at ordinal temperature or higher in an amphiphilic substance-N-long chain acyl acidic amino acid monosalt-oil-water system, said outer phase oil contains organophilic modified clay minerals and an emulsifying agent with a HLB of 7 or lower, and the weight ratio of the O/W type emulsion and the outer phase oil is 2:3-19:1. An O/W/O type multiple emulsion with superior stability over time and good usability.
An O/W/O type multiple emulsion in which an O/W type emulsion is dispersed in the outer phase oil wherein the O/W type emulsion in the inner phase contains water, an oil based ingredient, a surfactant and an amphiphilic substance chosen from the group consisting of those which can form a gel at ordinal temperature or higher in an amphiphilic substance-surfactant-oil-water system, said outer phase oil contains organophilic modified clay minerals and an emulsifying agent with a HLB of 7 or lower, and the weight ratio of the O/W type emulsion and the outer phase oil is 2:3-19:1.
