    AEO-9 / MOA-9 (Fatty Alcohol Ethoxylate 9EO) – CAS 9002‑92‑0

    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 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 SDS, 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.
    • Q:

      AEO-9 vs AEO-7 vs AEO-3: what's the difference?

      A: The number indicates the average moles of ethylene oxide (EO). AEO-9 (9EO) has the longest hydrophilic chain, giving the highest water solubility and best detergency. AEO-3 is more oil-soluble and used as an emulsifier or co-surfactant. AEO-7 offers intermediate performance.
    • Q:

      What is the HLB value of AEO-9?

      A: AEO-9 has an HLB (Hydrophilic-Lipophilic Balance) of approximately 12.5–14, making it suitable as an O/W emulsifier and detergent base. It is a water-soluble nonionic surfactant.
    • Q:

      Is AEO-9 compatible with anionic and cationic surfactants?

      A: Yes. As a nonionic surfactant, AEO-9 is compatible with anionic (e.g., LAS, SLES) and cationic (e.g., quaternary ammonium) surfactants. It also tolerates hard water and a wide pH range, making it ideal for multi-component formulations.
    • Q:

      What is the recommended dosage of AEO-9 in formulations?

      A: Typical dosage ranges: liquid detergents 5–15%, industrial cleaners 3–10%, textile auxiliaries 1–5%, and cosmetics 0.5–5%. Optimal concentration depends on the required detergency, emulsification, or wetting performance.
    • Q:

      How should AEO-9 be stored and handled?

      A: Store in a cool, dry, ventilated area away from direct sunlight and high temperatures. Keep containers sealed to prevent moisture absorption. Recommended temperature: 25–35°C. If solidified, warm gently to 40–50°C and mix before use. Wear protective gloves and goggles when handling.
    • Q:

      What documentation is available for AEO-9?

      A: We provide COA (Certificate of Analysis), TDS (Technical Data Sheet), and SDS (Safety Data Sheet) upon request. Batch-specific COA includes appearance, pH, cloud point, and residual EO content data.
