Lansurf AE310W
Product Category: Nonionics
C13 Alcohol with 10 moles of Ethylene Oxide
INCI Name: Alcohols, C11‑14‑iso‑, C13‑rich, ethoxylated
Lansurf AE310W is a nonionic surfactant based on a C13 synthetic primary alcohol ethoxylated with 10 moles of ethylene oxide. It is designed to deliver a balanced combination of emulsification, wetting, and detergency, making it suitable for a wide range of industrial and formulation applications.
​
The product is compatible with soaps, anionic, cationic, and other nonionic surfactants, providing excellent formulation flexibility. Lansurf AE310W exhibits strong oil‑in‑water and water‑in‑oil emulsification, along with rapid wetting and high detergency performance.
Due to its HLB value of approximately 13.5, Lansurf AE310W is particularly effective as a primary or secondary emulsifier and as a wetting agent in both aqueous and complex surfactant systems. It is also recognised as an excellent emulsifier for emulsion polymerisation, producing stable latex systems.
