 Polysorbate 20 (common commercial brand names include Scattics, Alkest TW 20 and Tween 20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan before the addition of lauric acid. Its stability and relative nontoxicity allows it to be used as a detergent and emulsifier in a number of domestic, scientific, and pharmacological applications. As the name implies the ethoxylation process leaves the molecule with 20 repeat units of polyethylene glycol; in practice these are distributed across 4 different chains leading to a commercial product containing a range of chemical species.

Polysorbate 20 Usage And Synthesis

Chemical Properties    Polysorbate 20 is a mixture of laurate partial esters of sorbitol and sorbitol anhydrides condensed with approximately 20 mole of ethylene oxide (C2H4O) for each mole of sorbitol and its mono- and dianhydrides. It has a faint, characteristic odor and a warm, somewhat bitter taste.
Chemical Properties    Yellow liquid
Uses    Pharmaceutic aid (surfactant).
Uses    polysorbate 20 is a solubilizer, emulsifier, viscosity modifier, and stabilizer of essential oils in water.
