OIL-IN-WATER TYPE EMULSIFIED COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain an oil-in-water type emulsified composition which effectively controls crystallization of an N-long-chain acyl basic amino acid derivative and its acid addition salt formulated in an oil-in-water type emulsified composition and has excellent storage stability. SOLUTION: In this oil-in-water type emulsified composition comprising the N-long-chain acyl basic amino acid derivative and its acid addition salt, the oil-in-water type emulsified composition is formulated with one or more kinds selected from an organic acid or its salt. One or more kinds selected from lactic acid and its salt are used as the organic acid or its salt. An N-cocoyl-L-arginine ethyl ester-DL-pyrrolidonecarboxylate is used as the N-long-chain acyl basic amino acid derivative and its acid addition salt. COPYRIGHT: (C)2004,JPO&NCIPI
