This article describes the method of preparation for cisplatin multiple-phase emulsion. Japanese emulsifying agent HCO-60,SO-l5 and polyvidone were used to increase the solubility of the cisplatin. The product of cisplatin multiple-phase emulsion had a small uniform granularity (The particle diameter over 99% is under 2. 0 μm)and the stability is fine. The entrapment rate of cisplatin multiple phase emulsion is more than 80%,By determining its electricelectrical conductivity, the phase into temperature is 6...
