OSTWALD RIPENING IN NANOEMULSIONS STABILIZED BY TWEEN AND SPAN
The rates of Ostwald ripening in nanoemulsions stabilized by Tween and Span mixtures were determined in this work. In the case of nanoemulsion stabilization by Tween 80 and Span 80, that are liquid at ambient temperature, the rate of Ostwald ripening was very high. Ostwald ripening was reduced significantly when liquid surfactants were replaced with solid ones. At that substitution, low HLB surfactant influenced stronger. Solid adsorption layer on the surface of oil droplets phase retarded d
