Span 80 (Cat No.: M050114), also known as Sorbitan monooleate, is a non-ionic surfactant derived from sorbitol and oleic acid. It is widely used as an emulsifier, dispersant, and stabilizer in pharmaceuticals, cosmetics, food products, and industrial formulations. Span 80 is oil-soluble and suitable for forming water-in-oil (W/O) emulsions. Its low hydrophilic-lipophilic balance (HLB) value makes it ideal for blending with other surfactants to fine-tune emulsion characteristics. It also finds application in drug delivery systems, agriculture, and textile processing due to its mildness and versatility.
