Patent ID: 8821905

Claim:
An oil-in-water emulsified composition comprising: 1-3 wt % of potassium 4-methoxysalicylate or L-ascorbic acid-2-glucoside; hydrophilic nonionic surfactant; an N-long chain acyl acidic amino acid mono salt selected from the group consisting of sodium stearoyl glutamate, sodium lauroyl glutamate, potassium myristoyl glutamate, and sodium myristoyl glutamate; two or more types of higher fatty acids and alkali that constitutes a higher fatty acid soap; a higher alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, myristyl alcohol, oleyl alcohol, cetostearyl alcohol, batyl alcohol, and isostearyl alcohol; oil component; and water; wherein the oil-in-water emulsified composition: is characterized by miniaturization of emulsified particles by means of high pressure emulsification under a pressure of 50 MPa or more down to an emulsified particle size range of 0.03-0.15 μm; has aqueous solution-like low viscosity physical properties; and has superior stability over time.
