The main chemical component of MOA-5 (AEO-5) is C12-14 fatty alcohol polyoxyethylene (5) ether (CAS No.: 68439-50-9), belonging to nonionic surfactants. This product is prepared by the addition polymerization reaction of natural source C12-14 fatty alcohols (mainly lauryl alcohol/dodecanol) as starters with ethylene oxide (EO), with an average addition number of 5 moles of ethylene oxide.
From the molecular structure perspective, it consists of two parts: one is the hydrophobic group - the long-chain fatty alkyl group of C12-14 (lauryl), providing lipophilicity; the other is the hydrophilic group - a polyoxyethylene chain composed of 5 oxyethylene units (-CH₂CH₂O-) and a terminal hydroxyl group (-OH), giving the product good water solubility and surface activity. This "hydrophobic-hydrophilic" amphiphilic structure enables it to orient at the oil/water interface, thereby performing functions such as emulsification, wetting, dispersion, and solubilization.
In similar naming systems, this product is also commonly referred to as polyoxyethylene (5) lauryl ether, dodecyl polyoxyethylene (5) ether, or lauryl alcohol polyoxyethylene (5) ether, all being synonymous names for the same chemical substance. The product appearance is a colorless to slightly yellow transparent liquid with good fluidity and compatibility with other formulations.
