Abstract

Silicone polymers are a class of hybridorganic/inorganic polymers, that show desirable surfaceproperties such a low surface energy and high flexibility,which enables even a very high molecular weight chainto achieve optimal orientation at the interface. Siliconepolymers have dual characteristics, because of whichthey can either be used as emulsifiers or act as thecontinuous/dispersed phase of the emulsion in presenceof surface active agents. Major characteristics of siliconeemulsions are discussed in this review along with newinformation on silicone surfactants used for emulsification.Finally an analysis of silicone emulsification technology ispresented along with their recent applications andsignificance to the modern day life style.
