Tween-80
Brief Introduction:
Polyethylene glycol sorbitan monooleate, also known as Polysorbate or Tween 80, is a commonly used nonionic surfactant with emulsifying, solubilizing, and decontamination effects.
Solubility:
Soluble in ethanol, vegetable oil, ethyl acetate, methanol, toluene, but insoluble in mineral oil. It becomes gelatinous at low temperatures and recovers when heated. It has a special odor and a slightly bitter taste. It is helpful for the dispersion of phthalocyanine green.
Preparation or Source:
It is produced by the reaction of sorbitan monooleate and ethylene oxide.
