Tween 80 (polysorbate 80, polyoxyethylene sorbitan monooleate) is a non-ionic surfactant that is widely used as an emulsifier in cosmetics, pharmaceuticals and food products.
The different types of surfactants were used in both steps as hydrophobic and hydrophilic emulsifiers, respectively. The effects of emulsifiers in modifying the size of the nanocapsules were compared with respect to their weighted hydrophilic-lipophilic balance (HLB) value, and the size was also affected by the content of the emulsifying agent.
