Abstract: The present invention relates to a cosmetic composition of a multiple emulsion formulation having a lamellar liquid crystal structure, and a method for preparing the same. More particularly, the cosmetic composition is prepared using different single emulsification type emulsions, i.e. a W/O type emulsion and an O/W type emulsion which has a lamellar liquid crystal structure, or using a mixture having constituent ingredients thereof. Thus, the present invention has effects of stably maintaining effective ingredients of the cosmetic composition, and enhancing the feeling of use.

Abstract: An oil-in-water type emulsion and a cosmetic composition having the same to an oil-in-water type emulsion in which an oil-phase part having a C12-C22 fatty acid, an oil and an emulsifier is dispersed in a water-phase part comprising a viscosity increasing agent, a neutralizing agent and water is disclosed. The wherein the oil-in-water type emulsion has a starch-based viscosity increasing agent as the viscosity increasing agent A cosmetic composition having the same is also disclosed. In spite of being an emulsified composition obtained through the neutralization of fatty acids, the oil-in-water type emulsion according to the present invention has excellent stability and is also excellent in view of the feeling of use, skin irritation, and stability on the skin, and thus enables the manufacture and use of various formulations of chemical products.
