Tween 80
Broad Industrial Application: Tween 80 is a highly adaptable emulsifier widely employed across the cosmetic, food, and pharmaceutical industries.
Efficient Production Method: It is manufactured through an alkaline catalytic process, which guarantees high production efficiency and consistent product quality.
High Chemical Reactivity: The emulsifier is synthesized by reacting each mole of sorbitol or sorbitan anhydride with 20 moles of ethylene oxide, significantly improving its emulsification performance.
Established Brand Heritage: Originally developed by ICI, Tween 80 carries the trusted reputation of the ICI brand within the global emulsifier market.
Tween 80 is a synthetic, non-ionic surfactant widely used as an emulsifier in the cosmetic, food, and pharmaceutical industries. Its production employs an alkaline-catalyzed reaction in which ethylene oxide is added to sorbitol fatty acid esters or sorbitan fatty acid esters. Specifically, each mole of sorbitol or sorbitan anhydride reacts with 20 moles of ethylene oxide. The product was originally developed by the American corporation ICI, which introduced "Tween" as the brand name for this series of emulsifiers. Different numerical designations—such as Tween 60 and Tween 80—indicate variations in the fatty acid composition used during synthesis.
