本文研究了注射液赋形剂中含苯甲醇及吐温80时影响产生混浊的因素,其中包括时间、温度、苯甲醇及吐温80的浓度及电解质如氯化钠的存在。测定了各种成份在不同浓度时表面张力的降低及昙点等数据,并对注射液处方(配方)的问题进行了讨论。在注射液处方中苯甲醇常与吐温80及氯化物配伍,Halaby 观察到在室温时含苯甲 In this paper, the factors that affect the turbidity of benzyl alcohol injection and Tween 80 injection were studied, including the time, temperature, the concentration of benzyl alcohol and Tween 80, and the presence of electrolytes such as sodium chloride. Determined the various components in different concentrations of surface tension reduction and the Tan point and other data, and injection prescription (formula) of the issue were discussed. Benzyl alcohol is often compatible with Tween 80 and chloride in injection formulations. Halaby observed that at room temperature,
