Sorbitan laurate (Span 20) is a mixture of the partial esters of sorbitol and its mono- and dianhydrides with edible lauric acid. It is an excipient. Sorbitan laurate is a non-ionic surfactant that is widely used as an emulsifier and stabilizer in pharmaceutical formulations, food and cosmetic industries. As a food additive, it is designated with the E number E493. Span 20 finds application in topical preparations. It is soluble in many fatty compositions and solvents and dispersible in water, dilute acids and alkalis. Recommended topical usage levels of 0.5-5%.
