MOA-5 (AEO-5), with the chemical name C12-14 fatty alcohol polyoxyethylene (5) ether and CAS number 68439-50-9, is a nonionic surfactant. This product appears as a colorless to slightly yellow transparent liquid with good fluidity and compatibility. The synergistic effect of ether bonds and hydroxyl groups in its molecular structure endows it with multiple functional advantages.
In terms of emulsifying ability, MOA-5 exhibits excellent emulsifying stability for various oil-phase systems, significantly reducing oil-water interfacial tension and forming fine and stable emulsions. For wetting and penetrating properties, it can quickly spread on solid surfaces, effectively improving the wetting effect of liquids on fibers, metals, and hard surfaces. Meanwhile, it has good dispersion stability for pigments, dyes, and organic active ingredients, enhancing the solubility of poorly soluble substances.
From the perspective of chemical stability, MOA-5 remains stable over a wide pH range and exhibits outstanding hard water resistance, with a low tendency to form precipitates with calcium and magnesium ions in water. Its formulation compatibility is also broad, allowing it to be used synergistically with anionic, cationic, and other nonionic surfactants, flexibly meeting various formulation design requirements.

Thanks to its balanced performance portfolio, MOA-5 is widely used in textile dyeing and printing (pretreatment scouring agent, leveling agent, soaping agent), leather processing (degreasing, soaking, fatliquoring), metal cleaners, hard surface cleaners, household detergents (laundry liquid, dishwashing detergent), pesticide emulsification, as well as coatings and inks. As a key surfactant component in formulations, it is recommended to determine the optimal dosage through experiments based on the specific application system.
