Sorbitan monostearate is an ester of sorbitan (a sorbitol derivative) and stearic acid and is sometimes referred to as a synthetic wax.^[1]

Uses

Sorbitan monostearate is used in the manufacture of food and healthcare products as a non-ionic surfactant with emulsifying, dispersing, and wetting properties.^{[citation needed]} It is also employed to create synthetic fibers, metal machining fluid, and as a brightener in the leather industry. Sorbitans are also known as "Spans".

Sorbitan monostearate has been approved by the European Union for use as a food additive (emulsifier) (E number: E 491).^[2] It is also approved for use by the British Pharmacopoeia.^[3]
