AEO‑9, also known as MOA‑9, is a nonionic surfactant produced by ethoxylation of fatty alcohols with approximately nine moles of ethylene oxide. Identified by the UVCB CAS No. 9002‑92‑0, it offers balanced detergency, emulsification, and wetting performance. AEO‑9 is widely used in detergents and industrial formulations where good solubility and cleaning efficiency are required. The product is supplied for industrial use with standard documentation including MSDS, TDS, and COA.

FAQ - Technical & Supply Chain
-
Q:
Why do different AEO grades share the same CAS number?
A: CAS 9002‑92‑0 represents a UVCB category covering fatty alcohol ethoxylates with different EO chain lengths. -
Q:
Is AEO‑9 biodegradable?
A: Yes. Fatty alcohol ethoxylates are generally readily biodegradable and are commonly used as APEO‑free alternatives.
