Nanoencapsulation of solid hydrophobic actives: influence of type of surfactants

Abstract:

The nanotechnology brings numerous advantages in the cosmetic field, this work evaluated the action of Sodium Laureth Sulfate, Cocamidopropyl Betaine and Polysorbate 20 in the formation of polymeric nanocapsules and in the encapsulation efficiency using the emulsion-diffusion of solvent method. It were developed three colloidal suspension containing a model hydrophobic active and three placebos. It was observed that the Cocamidopropyl Betaine promoted an increase in the particle size and that the Polysorbate 20 was responsible by decrease the encapsulation efficiency of model active in the system.
