Lansurf AE312W

Lansurf AE312W is a nonionic surfactant produced by the ethoxylation of a synthetic primary alcohol, resulting in a C13 alcohol ethoxylate containing 12 moles of ethylene oxide. The product provides an effective balance of oil‑in‑water and water‑in‑oil emulsification, combined with good wetting and detergency, making it suitable for a wide range of industrial and formulation applications.

​

Lansurf AE312W is supplied as a clear liquid free from foreign matter and is readily soluble in water, enabling ease of handling and formulation. Its performance characteristics make it particularly effective where strong emulsification and surface activity are required.

 

Key Features

 

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

• Great detergency, delivering high cleaning efficiency suitable for industrial, domestic, and institutional cleaning systems.

• Good wetting, demonstrated by favourable wetting performance, enabling rapid surface penetration in textile, paper, and cleaning applications.
