The biggest difference between Guoli Chemical's Dodecyl Polyoxyethylene Ether AC-1202 (also known as AEO-2 or Polyoxyethylene (2) Dodecyl Ether) and similar products (such as AC-1205, AC-1210, AC-1215) is its extremely low degree of ethoxylation. This molecular structure determines that its HLB value (Hydrophilic-Lipophilic Balance) is only about 6, much lower than other high-EO number products. Therefore, AC-1202 has strong hydrophobic and lipophilic characteristics, insoluble in water but highly soluble in organic solvents and oil phases, making it especially outstanding in formulating water-in-oil (W/O) emulsions and oil-based cleaning agents.
Compared to high-ethoxylated similar products, AC-1202 functionally focuses more on "strong penetration and rapid degreasing." Due to its shorter polyoxyethylene chain and smaller molecular size, it can quickly penetrate into tiny gaps of oil stains and substrates, achieving high efficiency in leather degreasing, heavy oil industrial cleaning, and metal degreasing. In addition, it is a typical low-foaming surfactant, which can significantly reduce downtime or overflow caused by foam in industrial cleaning lines and circulating water systems that require rapid defoaming or foam suppression.
Although both are fatty amine polyoxyethylene ethers, AC-1202 and products like AC-1860 each have their strengths. AC-1860 is a solid macromolecule formed by adding 60 EO to octadecylamine, specializing in high-temperature leveling and antistatic properties; while AC-1202 exhibits unique cationic characteristics under acidic conditions, combining bactericidal, corrosion inhibition, and antistatic functions. This dual nonionic and cationic nature imparted by the low EO number enables it to deliver composite effects in formulations such as acid pickling corrosion inhibitors and textile antistatic finishes that high-EO number products cannot replace.
