The present invention provides an oil-in-water emulsified composition comprising the following ingredients (A)-(G) characterized by miniaturization of the emulsified particles by means of high pressure emulsification: (A) salt type drug (B) hydrophilic nonionic surfactant (C) N-long chain acyl acidic amino acid mono salt (D) two or more types of higher fatty acids and alkali that constitutes higher fatty acid soap (E) higher alcohol (F) oil component (G) water. The object of the present invention is to provide an oil-in-water emulsified composition prepared by miniaturizing emulsified particles by means of a high pressure emulsification method, said composition being superior in terms of emulsification stability such that electrolyte salt type drugs can be stably blended in.본 발명은 하기 성분(A)~(G)를 함유 해 고압 유화에 의해 유화 입자를 미세화한 것을 특징으로 하는 수중유형 유화 조성물을 제공하는 것이다.(A) 염형약제(B) 친수성 비이온 계면활성제(C) N-장쇠아실산성 아미노산모노염(D) 2종 이상의 고급 지방산 및 고급 지방산 비누를 구성하는 알칼리(E) 고급 알코올(F) 유분(G) 물
