Lansurf AE36
Product Category: Nonionics
Tridecanol Ethoxylate with 6 Moles of Ethylene Oxide
INCI Name: Trideceth‑6
Lansurf AE36 is a biodegradable nonionic surfactant produced by the controlled ethoxylation of a synthetic C13 primary alcohol with 6 moles of ethylene oxide. This results in a versatile, anhydrous alcohol ethoxylate offering excellent emulsification, wetting, and detergency in both oil‑in‑water and water‑in‑oil systems. Its balanced performance profile makes it suitable for a broad range of industrial and domestic applications.
Lansurf AE36 is fully compatible with anionic, cationic, and other nonionic surfactants, enabling easy incorporation into multi‑component formulations. As an anhydrous product (<0% water), it delivers maximum active content and predictable performance in emulsification and detergent systems.
