Tween is produced by reacting sorbitol (Sorbitol) with a fatty acid such as lauric, palmitic, stearic or oleic acid to form an dehydrated sorbitan ester, which is then polymerised with Ethylene Oxide. Its molecular structure includes:
Hydrophilic part: Polyoxyethylene chain.
Hydrophobic part: fatty acid chain.
2. Common types
Tween series are divided into various types according to the fatty acids connected, the common ones are:
Tween 20: Laurate (Polysorbate 20)
Tween 40: Palmitate (Polysorbate 40)
Tween 60: Stearate (Polysorbate 60)
Tween 80: Oleate (Polysorbate 80)
3. Properties
Surface activity: excellent emulsifying, dispersing and wetting properties.
Water solubility: easily soluble in water, forming a transparent solution.
Stability: good stability in acid, alkali and electrolyte solutions.
Low toxicity: widely used in medicine and food industry.
4. Application fields
Food: used as food additives (e.g. emulsifier in ice cream, butter).
Cosmetics: as emulsifier and stabiliser in emulsion and cream.
Industry: used as dispersant and wetting agent in paints, coatings, textiles and pesticides.
5. Safety and Storage
Safety: Low toxicity, but high concentrations may cause slight irritation to skin and eyes.
Storage: Should be stored in a cool, dry place, avoid high temperature and humidity.
Summary
Tween is a class of multifunctional, low-toxicity, non-ionic surfactants widely used in food, cosmetic and industrial applications. Its excellent emulsifying, dispersing and wetting properties make it an essential ingredient in many formulations.
