(57) 【Abstract】 PROBLEM TO BE SOLVED: To exhibit creamy, moisturizing feeling and moisturizing effect while having low viscosity and physical properties of an aqueous solution, and also weakly acidic, emulsion stability and pH stability. An oil-in-water emulsion composition having excellent properties is provided. SOLUTION: In an N-long-chain acyl acidic amino acid monosalt-amphiphile-water system, (A) N-long-chain acyl acidic amino acid monosalt and (B) selected from those capable of forming a gel at room temperature. ) An amphipathic substance, water, and an oil content are contained, and substantially all of (A) and (B) are present at the oil droplet interface, and the viscosity of the system is 30 cps or less. |
