Lansurf AE109W

C10 Alcohol Ethoxylate With 9 Moles of Ethylene Oxide

Lansurf AE109W is a nonionic surfactant produced by the ethoxylation of 2‑propyl heptanol with 9 moles of ethylene oxide. This degree of ethoxylation provides an excellent balance of detergency and wetting performance, making the product suitable for a wide variety of applications. It also offers a favourable environmental profile and is readily biodegradable, supporting the development of more sustainable formulations

​​​

Key Features

​

​• Strong detergency and wetting performance - Its 9‑mole ethoxylation level provides excellent detergency and effective wetting, making it suitable for industrial and household cleaning applications.
• Readily biodegradable with a favourable environmental profile - Lansurf AE109W supports sustainable formulation development due to its high biodegradability.
• Effective substitute for C9–11 ethoxylates (8–10 EO) - Offers comparable performance, making it a strong replacement option in formulations requiring improved sustainability.
