Lansurf AE320W

Lansurf AE320W is a nonionic surfactant produced by the ethoxylation of a synthetic primary alcohol, corresponding to a C13 alcohol ethoxylate containing approximately 20 moles of ethylene oxide. The product is fully compatible with soaps, anionic, cationic, and other nonionic surfactants, and delivers effective wetting, detergency, and both oil‑in‑water and water‑in‑oil emulsification.

​

Due to its higher degree of ethoxylation and high HLB value, Lansurf AE320W is particularly suited for applications requiring strong hydrophilicity, rapid wetting, and stable emulsification. It performs exceptionally well as an emulsifier in emulsion polymerisation, enabling the formation of stable polymer latexes in a wide range of monomer systems, including vinyl acetate, styrene, and acrylics.

​

Key Features

​

• High‑performance emulsifier - Effective in both oil‑in‑water and water‑in‑oil systems, including emulsion polymerisation.

• Strong wetting and detergency - High hydrophilicity (HLB ~16.5) provides rapid wetting and reliable cleaning performance.

• Broad formulation compatibility - Compatible with soaps, anionic, cationic, and nonionic surfactants, offering excellent formulation flexibility.
