Polyoxyethylene Sorbitan Fatty Acid Ester (TWEEN)

Polyoxyethylene Sorbitan Fatty Acid Ester, commonly known as Tween, is a nonionic surfactant produced by the ethoxylation of sorbitan fatty acid esters. It is widely used as an emulsifier, solubilizer and dispersing agent due to its good compatibility with water and oil phases.

Polykem focuses on supplying TW-20, TW-40, TW-60 and TW-80 grades for industrial end uses—coating additives, textile auxiliaries and oilfield chemical systems. We provide documentation and customized packaging for bulk industrial buyers; for pharmaceutical or personal-care grade requirements, please contact us to confirm suitability and request the relevant technical documents.

Key Performance Features

Tween products help stabilize oil-water systems and are widely used where consistent emulsification is required.

Emulsification Performance

Tween products help stabilize oil-water systems and are widely used where consistent emulsification is required.

Solubilization Ability

They can improve the dispersion and incorporation of oil-soluble or poorly water-soluble ingredients in aqueous systems.

Wetting and Dispersion

Tween surfactants support better wetting and ingredient distribution in industrial and formulation applications.

Good Compatibility

As nonionic surfactants, Tween grades are compatible with many other surfactants and formulation ingredients.

Applications

 - Coating: Eliminate craters and enhance leveling property

 - Textile: High-efficiency penetrant, shortening processing time

 - Oilfield: Components of salt-resistant oil displacement agents

 - Agrochemical: Enhance the foliar adhesion rate of pesticides

 - Personal Care, Pharmaceutical and Food Applications

Selected grades, such as Tween 20 and Tween 80, are used in personal care, pharmaceutical and food-related applications where emulsification and solubilization properties are required. Please contact Polykem for grade information and supporting documents.

FAQ

What is the difference between TWEEN and SPAN?

TWEEN is generally more hydrophilic and commonly used in oil-in-water systems, while SPAN is more lipophilic and often used in water-in-oil systems. They can also be combined to adjust the HLB value. Learn more about Sorbitan Laurate (SPAN).

Does Polykem provide free samples?

Yes. Free samples are available for customers to evaluate grade suitability and formulation performance before bulk purchasing.
