摘要
Nanoemulsion as small droplet dispersion allows them to uniformly deposit on substrates,increases the rate of bioavailability,absorption and has a better uptake.Although it is generally accepted that nanoemulsions are stable for years,Oswald ripening which can damage nanoemulsion has been reported[1].In this study,converting nanoemulsion as liquid formulation into solid powders was attempted by using spray drying method.The obtained powders were then characterized,reconstituted and compared to the initial nanoemulsion.
