The main chemical component of MOA-3 (AEO-3) is C12-14 fatty alcohol polyoxyethylene (3) ether (CAS No.: 68439-50-9). This product is produced by the addition polymerization reaction of C12-C14 carbon chain natural fatty alcohols (mainly lauryl alcohol, i.e., dodecanol) with 3 moles of ethylene oxide (EO), belonging to the fatty alcohol polyoxyethylene ether class of nonionic surfactants. "MOA" stands for "lauryl alcohol polyoxyethylene ether," and the number "3" indicates an average ethylene oxide addition number of 3.
From the perspective of chemical composition and structure, its molecule consists of two parts: the lipophilic end is a C12-C14 long-chain fatty alkyl group, providing good oil solubility; the hydrophilic end is a polyoxyethylene chain segment composed of 3 ethylene oxide units. Due to the low EO addition number (only 3), the product's lipophilicity is significantly stronger than its hydrophilicity, with an HLB value of about 8-9, thus exhibiting excellent water-in-oil (W/O) emulsifying ability.
The product appearance is a colorless to slightly yellow transparent liquid, with high active content, stable chemical properties, and good resistance to acids, alkalis, and hard water. It is a typical representative of low-degree-of-polymerization nonionic surfactants.
