Polysorbates are a class of emulsifiers. They are used in manufacturing of some pharmaceuticals and preparation of food. Typically they are used in cosmetics and aggro chemical formulations as they work as anti-fogging agents. They are also used as solubilizers in flavors, perfumes and essential oils. Common names of polysorbates are Alkest, Scattics, Canarcel and Tween.

Polysorbates 20 and 80 are utilized as a part of the definition of biotherapeutic items for both counteracting surface adsorption and as stabilizers against protein collection. The polysorbates are amphipathic, nonionic surfactants made out of unsaturated fat esters of polyoxyethylene sorbitan being polyoxyethylene sorbitan monolaurate for polysorbate 20 and polyoxyethylene sorbitan monooleate for polysorbate 80.
Polysorbate 40 is a blend of palmitate esters of sorbitol and sorbitol anhydrides, consisting predominantly of the monoester, consolidated with roughly 20 moles of ethylene oxide. It works as surfactants, emulsifying agent.
Polysorbate 60 is a sorbitol-based emulsifier and surfactant. Its basic functions are fragrance ingredient; surfactant – emulsifying agent; surfactant – solubilizing agent. As per FDA polysorbate 60 is safe for consumption. It is used as an emulsifier in dessert toppings and usually mixed with polysorbate 65 or polysorbate 80.
