Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are commonly used in oral and topical pharmaceutical dosage forms. They are also often used in cosmetics to solubilize essential oils into water-based products. Polysorbates are oily liquids derived from ethoxylatedsorbitan (a derivative of sorbitol) esterified with fatty acids. Common brand names for polysorbates include Kolliphor,[1] Scattics, Alkest, Canarcel, Tween,[2] and Kotilen.
