Rheology of palm olein emulsions stabilized by non-ionic surfactants as potential carriers for drug delivery

Palm olein emulsions were prepared by homogenising the oil with varied ratios of sorbitan monolaurate (Span 20®) and polyoxyethylene 20 sorbitan monolaurate (Tween 20®). Viscosity changes of these emulsions with and without Tragacanth gum, were measured. The viscosity of emulsions increased drastica...
