Fatty alcohol polyoxyethylene ether (AEO / MOA / Laureth) full model
Mainstream carbon chain C12-C14 (dodecyl- to tetradecyl alcohol); AEO-n / MOA-n, n=EO ethylene oxide addition molar number; foreign trade name Laureth-n.
CAS Note:
C12‑14 AEO‑3~AEO‑20：68439‑50‑9
Brij-35 (Lauryl alcohol-23EO, pure C12): 9002-92-0. Many suppliers generically list the AEO series as 9002-92-0. For foreign trade documents, it is essential to specify "Alkyl chain: C12-C14; Average EO moles: XX" to avoid discrepancies in product specifications.
C12-C14 AEO (MOA) Series Summary Table (25°C)

| AEO‑4 (MOA‑4) | Colorless transparent liquid | 9‑10 | Water‑number:25‑35 | Oil‑phase emulsification, dry‑cleaning agent, silicone oil emulsification |
| AEO‑5 (MOA‑5) | Colorless transparent liquid | 10‑11 | ca. 30℃ | Oil‑water intermediate, textile auxiliaries, solvent emulsification |
| AEO‑7 (MOA‑7) | Colorless to pale‑yellow paste | 12 | 52‑58℃ | Strong degreasing & penetrating power; industrial cleaning agent, textile scouring, laundry detergent, pesticide emulsifier |
| AEO‑9 (MOA‑9) | Milky‑white paste | 13‑14 | 73‑79℃ | Main grade for daily‑use chemicals; laundry liquid, dish‑washing detergent; aqueous‑phase emulsification & scouring |
| AEO‑10 (MOA‑10) | Milky‑white paste | 14 | 78‑84℃ | High detergency, textile boiling‑off & scouring, liquid detergent |
| AEO‑15 (MOA‑15) | White paste / waxy solid | 15 | 88‑92℃ | Solubilizer, levelling agent; fragrance solubilization; textile dye levelling |
| AEO‑20 (MOA‑20) | White waxy solid | 16 | ＞95℃ | Levelling agent, antistatic agent, solubilizer; textile scouring & boiling‑off |
| AEO‑23 (Brij‑35) | White waxy solid | 16.9 | 91‑95℃ | Laboratory reagent; protein solubilization; high‑hydrophilic solubilizer (CAS:9002‑92‑0) |
Physical properties: The higher the EO number, the stronger the hydrophilicity; Appearance: Liquid → Paste → Waxy solid; The higher the turbidity point, the better the water solubility.
Other carbon chain series (occasionally encountered in foreign trade)
