Surfactant effect on the physicochemical characteristics of γ-oryanol-containing solid lipid nanoparticles

Surfactants employed in production of solid lipid nanoparticles (SLNs) play a major role on physical stability of nanoparticles, and the extent of drug dissolution and permeability into cells. In this study, cationic (cetyl pyridinium chloride), anionic (sodium dodecyl sulfate) and non-ionic (Tween 80) surfactants, as well as its combinations, were employed to formulate compritol based SLNs using γ-oryzanol as a model drug. The physicochemical...
