Tween 80 (Polysorbate 80)

Tween 80, or Polysorbate 80, is a non-ionic surfactant and emulsifier derived from the ethoxylation of sorbitan monooleate. It is a pale yellow to amber viscous liquid with a mild odor and is completely soluble in water and many polar solvents. Tween 80 is widely used in food, pharmaceuticals, cosmetics, biotechnology, and industrial applications. Its high Hydrophilic-Lipophilic Balance (HLB ~15) makes it particularly effective in stabilizing oil-in-water emulsions and solubilizing lipophilic substances.
