Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are non-ionic surfactants and emulsifiers derived from polyethoxylated sorbitan and stearic or oleic acid. Polysorbates are mainly used as a solubilizer, emulsifier or suspension stabilizer for pharmaceutical application. Depending on the HLB value of the product they can either act as solubilzer or emulsifier.
