外用乳膏剂的杀菌效能主要取决于乳膏剂内杀菌剂的性质及其在此系统中水相中的浓度,而此浓度又取决于杀菌剂在水、油相内的分配系数。本文研究了有杀菌作用的季铵化合物在单一分配系统和乳膏剂中分配特征的相互关系。研究表明,在水 The effectiveness of topical creams depends largely on the nature of the antiseptic in the cream and its concentration in the aqueous phase of the system, which in turn depends on the partition coefficient of the antiseptic in water and oil phase. In this paper, the interrelationship between the distribution characteristics of quaternary ammonium compounds with bactericidal action in a single distribution system and in creams was investigated. Research shows that in water
