MOA-9 (AEO-9), with the chemical name C12-14 alcohol polyoxyethylene (9) ether, is a high-polymerization-degree fatty alcohol polyoxyethylene ether nonionic surfactant. Leveraging its excellent emulsifying, wetting, penetrating, dispersing, and detergency properties, as well as its outstanding stability towards acids, alkalis, and hard water, MOA-9 plays an irreplaceable role in many industrial fields and household products. It can be flexibly compounded with anionic, cationic, and other nonionic surfactants, offering high freedom in formulation design.
In the textile printing and dyeing industry, MOA-9 is a core component of scouring agents and leveling agents, effectively removing fiber impurities, promoting uniform dye uptake, and enhancing fabric hand feel and whiteness. In industrial and household cleaning, it provides excellent detergency and emulsifying power, suitable for dishwashing, laundry, and hard surface cleaning, with low foaming, high efficiency, and easy rinsing. In metal processing, MOA-9 quickly penetrates and emulsifies oil stains and processing residues on metal surfaces, making it an ideal choice for pre-treatment in electroplating and painting, as well as cleaning mechanical parts.
Furthermore, MOA-9 serves as an efficient emulsifier in pesticide emulsifiable concentrates, ensuring the active ingredients spontaneously emulsify into stable emulsions in water; in the waste paper deinking process of the paper industry, it effectively removes ink particles and prevents redeposition; in cosmetic creams, lotions, and makeup removers, it acts as a mild emulsifier and fragrance solubilizer; and in industrial fluids such as metalworking fluids, textile oils, and drilling fluids, it stably emulsifies and disperses mineral oils and natural fats, preventing separation and precipitation.

Formulation Flexibility: MOA-9 exhibits excellent stability in acidic, alkaline, and hard water media, and can be compounded with anionic, cationic, and other nonionic surfactants. In hard water environments, it can partially replace anionic surfactants to improve the overall hardness tolerance of the formulation.
Recommended Dosage: Depending on the specific application, the recommended addition amount in general formulations is 2% to 15% (based on total weight). In emulsification systems, adjust the proportion according to the oil phase type and target HLB value. The optimal dosage should be determined through small-scale trials.
Process Considerations: MOA-9 may be paste-like at low temperatures. It is recommended to preheat it at 25-40°C before use to facilitate feeding and dispersion. When preparing emulsions, it is advisable to pre-dissolve MOA-9 in either the oil phase or water phase, then slowly add the other phase under high shear conditions to achieve the best emulsification effect.
