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.本發明提供一種水中油型乳化組成物，含有下述成分(A)～(G)，且利用高壓乳化使乳化粒子細微化。(A)鹽型藥劑(B)親水性非離子界面活性劑(C)N-長鏈醯基酸性胺基酸單鹽(D)2種以上之高級脂肪酸及構成高級脂肪酸皂之鹼(E)高級醇(F)油分(G)水本發明之目的在於提供一種水中油型乳化組成物，其利用高壓乳化法使乳化粒子細微化，且可穩定調配電解質之鹽型藥劑，乳化穩定性極其優異。
