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, formingfine, 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 itsmild and gentle nature, Tween 20 is often preferred in formulations requiringlow irritation and high safety margins.
