Nano-emulsions are oil-in-water (O/W) or water-in-oil (W/O), transparent or translucent, colloidal dispersions, usually in the 20-500 nm size range [4,5]. An advantage in using nano-emulsions compared to ordinary emulsion, is their ability, as delivery systems, to improve the bioa- vailability and bioefficacy of lipophilic bioactives in their delivery [6]. The very small droplet size causes a large reduction in the force of gravity, and the Brownian motion may be sufficient for overcoming it. This means that no creaming, sedimentation and flocculation occurs during storage. Weak flocculation is prevented, which enables delivery system to remain dispersed with no separation [7].
