Polysorbate 20 is an esterification product of lauric acid with sorbitol, ethoxylated (on average 20 units -CH2-CH2-O-). The substance is used in cosmetic formulations where it acts as an emulsifier (surface-active substance used in cosmetic preparations as an additive to combine two immiscible liquids - e.g. oil and water - to form an emulsion) and surfactant (washing-active substance; improves the even distribution of the products during application).
