Ethanol injection is one of the techniques frequently used to produce liposomes which favors both simplicity and safety. In this process, an ethanolic solution of lipids is rapidly injected into an aqueous medium through a needle, dispersing the phospholipids throughout the medium and promoting the vesicle formation. Being a critical parameter that determines the fate of liposome and its distribution, we studied different factors affecting the particle size of liposomes including different phospholipid (Phosal(®) 53 MCT) and cholesterol concentrations and the use of different types of non-ionic surfactants at fixed Phosal(®) 53 MCT concentration of 50 mg per formulation...
