Dodecylamine Polyoxyethylene Ether AC-1202 is a nonionic surfactant produced by the addition reaction of primary dodecyl fatty amine (dodecylamine, i.e., laurylamine) as the starting material with ethylene oxide (EO) under the action of a catalyst. Its general chemical structure is R-N[(CH₂CH₂O)ₙH][(CH₂CH₂O)ₘH], where R is a dodecyl group (C₁₂H₂₅), and n+m represents the degree of ethoxylation (i.e., the number of EO additions).
From the product naming, in "AC-1202," the "12" indicates that the fatty amine carbon chain is dodecyl (lauryl), and the "02" indicates an ethoxylation degree of 2 moles of ethylene oxide addition. Therefore, the chemical name of its active ingredient is Polyoxyethylene (2) dodecylamine, with a corresponding CAS number of 26635-75-6. In an acidic medium, the amine group can undergo protonation, exhibiting cationic characteristics, thus providing dual functionality as both a nonionic and cationic surfactant.

It should be noted that AC-1202 differs from common fatty alcohol polyoxyethylene ether AEO-2 (lauryl alcohol polyoxyethylene ether, CAS: 9002-92-0) in terms of raw materials: AC-1202 uses fatty amine (containing nitrogen) as the starting material, while AEO-2 uses fatty alcohol (containing hydroxyl groups). The tertiary amine structure in the AC-1202 molecule provides cationic properties under acidic conditions, which is a unique characteristic not present in ordinary fatty alcohol polyoxyethylene ethers, giving it broader application adaptability in fields such as pesticide emulsification, metal processing, and textile auxiliaries.
