MOA-9 (AEO-9), chemically known as C12-14 alcohol polyoxyethylene (9) ether, also goes by the names Peregal O-9, Leveling Agent O, Emulsifier O-9, Fatty Alcohol Polyoxyethylene (9) Ether, etc. (CAS No.: 68439-50-9). The product appears as a colorless to slightly yellow transparent liquid or white paste, with high active matter content, and can be well dispersed or dissolved in water.
As a classic nonionic surfactant, MOA-9 possesses four core characteristics: Excellent emulsifying ability — effectively reduces oil-water interfacial tension to form stable emulsions; Superior wetting and penetrating properties — quickly wets various substrate surfaces; Outstanding dispersing and cleaning performance — good suspension and dispersion effect on solid dirt particles; Broad chemical compatibility — remains stable in acidic, alkaline, and hard water media, and can be flexibly compounded with anionic, cationic, and other nonionic surfactants.
This product is manufactured by Haian Guoli Chemical Co., Ltd., has good biodegradability, and is an ideal choice for formulations that balance efficacy and environmental friendliness.
As a core component of scouring agents, leveling agents, etc., it effectively removes fiber impurities, promotes uniform dye uptake, and improves fabric hand feel and whiteness. It plays a key role in pretreatment, dyeing, and finishing processes.
Provides excellent detergency and emulsifying power, suitable for dishwashing, laundry, and hard surface cleaning. Low foaming and highly efficient, easy to rinse. Can replace some anionic surfactants to enhance the overall hard water resistance of the formulation.
Quickly penetrates and emulsifies oil stains and processing residues on metal surfaces, suitable for electroplating, coating pretreatment, and mechanical parts cleaning, ensuring subsequent process quality.
Has good emulsifying and dispersing ability for natural oils, assists in degreasing in multiple processes, and can be used as a component of fatliquoring agents to improve leather softness.
Used in the formulation of pesticide emulsifiable concentrates (EC) to ensure that the active pesticide ingredients spontaneously emulsify in water, forming stable emulsions, improving efficacy, and ensuring safe application.
Efficiently strips ink particles during waste paper recycling and prevents redeposition, while improving the rewettability of the paper sheet, enhancing fiber utilization.
Suitable for creams, lotions, cleansing oils, etc., used as a mild emulsifier and fragrance solubilizer. Low skin irritation and broad compatibility.
In industrial fluids such as metalworking fluids, textile oils, and drilling fluids, it stably emulsifies and disperses mineral oils and natural oils, preventing separation and precipitation.
