Sorbitan Ester Ethoxylates (Polysorbates)
Polysorbates are oily liquids produced by ethoxylation of sorbitan esterified with fatty acids. The number 20 following the polyoxyethylene part refers to the total number of oxyethylene -(CH2CH2O)- groups found in the molecule. The number following the polysorbate part is related to the type of fatty acid associated with the polyoxyethylene sorbitan part of the molecule.
Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are often used in cosmetics to solubilize essential oils into water-based products.
