悬浮乳剂加工时,通常将固体原药加工成悬浮剂,液体或低熔点原药加工成高浓度乳油,在搅拌状态下,将乳油滴加入悬浮剂体系中,形成均一、流动性好的分散体。悬浮乳剂是油相、水相、固体等三相混合体,研制过程中极易形成膏化、聚结、分层、涨气、结块,特别是高浓度的悬浮乳剂体系,常常表面制备过程中假塑性膏化或硬化。
Suspension emulsion processing, usually solid raw material processed into a suspension agent, the liquid or low melting point of the original drug processed into a high concentration of emulsifiable concentrate, the emulsion was added dropwise to the suspension system, to form a homogeneous, fluid dispersion . Suspension emulsions are oil phase, water phase, solid phase, such as three-phase mixture, the development process is extremely easy to form cream, coalescence, stratification, up gas, agglomeration, especially high concentration suspension emulsion system, often surface preparation process In the pseudoplastics cream or hardened.
