Tween 20 Emulsifier

Chemical Name: Polysorbate 20 / Polyoxyethylene (20) Sorbitan Monolaurate
Chemical Formula：C₅₈H₁₁₄O₂₆
CAS Number：9005-64-5
Molecular Weight：1,226 g/mol
Functional Benefits of Tween 20 Emulsifier
As a high-HLB nonionic surfactant, Tween 20 effectively lowers interfacial
tension between oil and water, forming fine, uniform, and highly stable
emulsions.
Key functional advantages include:
Excellent oil-in-water emulsification
Strong solubilizing power for oils and actives
Superior wetting and dispersing ability
High clarity in aqueous systems
Good stability across a wide pH range
Compatibility with electrolytes, acids, alkalis, and other surfactants
Due to its mild and gentle nature, Tween 20 is often preferred in formulations
requiring low irritation and high safety margins.
