Key Properties
Span 20, also known as sorbitan monolaurate, is a nonionic surfactant and emulsifier that is widely utilized in various industries due to its ability to stabilize water-in-oil emulsions. It is particularly valued for its low hydrophilic-lipophilic balance (HLB) which makes it suitable for formulations requiring a water-in-oil emulsion system. Span 20 is derived from sorbitol and lauric acid, and its unique properties allow it to function effectively in a range of applications, including cosmetics, pharmaceuticals, and food products. Its versatility and effectiveness as an emulsifier make it a staple in formulation chemistry.
Also known as Span 20, Sorbitan Monolaurate.

- Substance
Span 20 appears as an amber to brown liquid with a density of 1.032 g/mL. It has a viscosity that can vary depending on the concentration and temperature, typically ranging from 100 to 500 cP at 25°C. The melting point of Span 20 is approximately 10°C, while its boiling point is around 300°C. It is soluble in oils and organic solvents but has limited solubility in water, which is characteristic of low HLB emulsifiers. The product has a mild odor, typical of fatty acid derivatives, and is stable under normal storage conditions.
