Lansurf AE315W

Lansurf AE315W is a nonionic surfactant produced by the reaction of ethylene oxide with a synthetic primary alcohol. It is a C13 alcohol ethoxylate containing approximately 15 moles of ethylene oxide. The product exhibits excellent oil/water and water/oil emulsification, along with effective wetting and detergency properties.

​

Lansurf AE315W is particularly well suited for use as an emulsifier in emulsion polymerisation, where it helps produce stable polymer latexes. It is widely applied in systems based on vinyl acetate, styrene, and acrylic monomers, including both homopolymers and copolymers.

​

Key Features

​

• Good emulsification, providing strong oil‑in‑water and water‑in‑oil emulsifying performance for a wide range of formulation systems.

• High detergency, delivering excellent cleaning efficiency suitable for industrial, institutional, and domestic detergent applications.

• Superior wetting, demonstrated by favourable wetting performance (Draves), enabling rapid surface penetration in textiles, coatings, paper, and cleaning formulations.
