Tween 80 CAS: 9005-64-5
Wide Industrial Usage: Tween 80 is a highly versatile emulsifier extensively applied in the cosmetics, food, and pharmaceutical sectors.
Efficient Manufacturing Process: It is produced via an alkaline-catalyzed reaction method, ensuring high production efficiency and stable product quality.
Strong Chemical Reactivity: This emulsifier is synthesized by reacting one mole of sorbitol or sorbitan anhydride with 20 moles of ethylene oxide, which greatly enhances its emulsifying performance.
Well-Known Brand Background: Initially developed by ICI, Tween 80 maintains a reliable and recognized brand image in the global emulsifier market.
Tween 80 is a synthetic nonionic surfactant that functions as a professional emulsifier widely used in cosmetics, food production, and pharmaceutical preparations. It is produced through an alkaline-catalyzed ethoxylation process, where ethylene oxide is added to sorbitol fatty acid esters or sorbitan fatty acid esters. In the synthesis process, every one mole of sorbitol or sorbitan anhydride reacts with 20 moles of ethylene oxide. This series of emulsifiers was originally created by the US-based company ICI, which launched the well-known "Tween" brand. Different product numbers like Tween 60 and Tween 80 represent different types of fatty acid components used in the manufacturing process.
