Product Name:Tween 40
English Name:Tween 40
CAS No.:9005-66-7
Aliases:Polyoxyethylene sorbitan monopalmitate, Polysorbate 40, Tween 40
Molecular Formula:C62H122O26
Physical Properties:This product is a yellow to amber viscous liquid with a slight characteristic odor and bitter taste. It is readily soluble in water, ethanol, methanol, and ethyl acetate, insoluble in mineral oil and vegetable oil, but dispersible in fatty acids and fatty amines. HLB value is about 15.6, density approximately 1.08 g/mL at 25°C, flash point greater than 149°C, and cloud point about 76°C (1% aqueous solution).
Uses:As a nonionic surfactant, it is mainly used as an emulsifier, dispersant, wetting agent, and solubilizer. It is widely applied in pharmaceutical preparations, cosmetics, food, and industrial fields, often used as an oil-in-water emulsifier.
Technical Specifications:
Purity ≥99%
Appearance: yellow to amber viscous liquid
Acid value ≤2.0 mg KOH/g
Saponification value 40-55 mg KOH/g
Hydroxyl value 90-120 mg KOH/g
