Non-ionic emulsifier – an ester of sorbitol and stearic acid. Stabilizes w/o (water-in-oil) emulsions in creams, balms, body care. Usually paired with polysorbate-60 for system stability. Biocompatible, non-irritating.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
Functional emulsifier. Safety confirmed by CIR. No standalone activity.
Sorbitan Stearate (Span 60) is a non-ionic emulsifier ester of sorbitol and stearic acid. HLB around 4.7. Stabilises water-in-oil emulsions, usually paired with a hydrophilic emulsifier (Polysorbate 60) for system stability. Mechanism. Lowers interfacial tension. The liquid-crystalline structure holds the oil and water phases in a stable emulsion through long storage and temperature swings. Where applied. Face and body creams, balms, mature- and dry-skin products. In Spain it features in Eucerin, Bioderma, Sesderma emulsions. Safety. CIR confirmed safety across all cosmetic types up to 5%. Non-sensitizing, non-comedogenic. Biocompatible, approved as a food additive. Pregnancy and lactation – safe.
