    AEO‑20 / MOA‑20 Polyoxyethylene (20) Lauryl Ether CAS 68439‑50‑9

    AEO‑20, also marketed as MOA‑20, is a high‑EO nonionic surfactant based on lauryl alcohol ethoxylated with approximately 20 moles of ethylene oxide. Identified by CAS No. 68439‑50‑9, it offers excellent water solubility, emulsification, and solubilization performance in aqueous systems. AEO‑20 is commonly used as an emulsifier and solubilizer in industrial surfactant formulations where high HLB value and formulation stability are required. The product is supplied for industrial formulation use with standard documentation including MSDS, TDS, and COA.

    Application Areas

    Cosmetics: emulsifiers, thickeners, anti-static agents (note that they may cause skin allergies).
    Textile industry: leveling agent, stripping agent, detergent (dosage 0.2-1 g/L).
    Detergents: liquid detergents, metal cleaning agents, industrial emulsifiers.
    Other: Pesticide emulsifiers, crude oil demulsifiers, lubricating oil emulsifiers.

    ‌Storage conditions

    Storage conditions: It should be stored in a dry, well ventilated place, away from sources of fire and high temperature environments. Avoid storing together with strong acids, strong bases, and other chemical substances to prevent chemical reactions. ‌
    Packaging and transportation: Usually packaged in 50kg/drum or 200kg/drum, attention should be paid to moisture and sun protection during transportation to ensure good container sealing.

    ‌‌Safety precautions

    Toxicity: Belongs to low toxicity substances, may be harmful to aquatic organisms, and should be avoided from being discharged into the environment.
    Protective measures: Wear protective goggles and gloves during operation to avoid inhaling dust or steam.

    FAQ - Technical & Supply Chain

    • Q:

      Does AEO‑20 have a fixed molecular formula?

      A: No. AEO‑20 is a fatty alcohol ethoxylate with an average EO number, so no single fixed molecular formula exists.
    • Q:

      Is AEO‑20 the same as MOA‑20?

      A: Yes. AEO‑20 and MOA‑20 refer to the same polyoxyethylene (20) lauryl ether, though specifications may vary by supplier.
