MOA-5 (AEO-5), chemically known as C12-14 fatty alcohol polyoxyethylene (5) ether (CAS number: 68439-50-9), is a classic nonionic surfactant. The synergistic effect of the ether bond and hydroxyl group in its molecular structure endows the product with excellent emulsifying ability, superior wetting and penetrating properties, and efficient dispersing and solubilizing functions. With its balanced performance combination and outstanding chemical stability, this product maintains stable performance in a wide range of acidic and alkaline environments, exhibits excellent hard water resistance, and can be used in combination with anionic, cationic, and other nonionic surfactants. Therefore, it has become an indispensable functional auxiliary in many industrial and civilian fields.
From the perspective of process suitability, MOA-5/AEO-5 mainly serves three major process scenarios: First, cleaning and decontamination processes (such as metal cleaning, hard surface cleaning, and household washing), leveraging its ability to quickly spread, wet, and peel off oil stains; second, emulsification and dispersion processes (such as pesticide emulsification and coating/ink systems), utilizing its ability to reduce interfacial tension, stabilize emulsions, and disperse pigments; third, penetration and treatment processes (such as textile pretreatment and leather soaking and fatliquoring), relying on its ability to deeply penetrate fibers or material interiors and promote uniform absorption of chemicals.
Based on actual application information in the product database, the following are the specific application processes of MOA-5/AEO-5 in various industries:
| Application Industry | Specific Process Step | Functional Role |
|---|---|---|
| Textile Printing and Dyeing | Pretreatment scouring, level dyeing, finishing, soaping | Removes oil stains and impurities from fabrics, improves dye penetration and leveling effect, ensuring uniform and full dyeing |
| Leather Processing | Degreasing, soaking, fatliquoring | Helps chemicals rapidly penetrate into the leather fiber interior, enhancing leather softness and fullness |
| Metal Cleaning | Spray cleaning, immersion cleaning | Rapidly wets metal surfaces, emulsifies and disperses oil stains, cutting fluids, and polishing wax residues; low foam and easy to rinse |
| Hard Surface Cleaning | Kitchen cleaning, bathroom cleaning, industrial hard surface cleaning | Has good wetting and stripping ability for grease and dirt; combined with auxiliaries achieves rapid decontamination |
| Household Washing | Laundry liquid, dishwashing detergents | Provides excellent degreasing and decontamination performance, moderate foam, easy to rinse |
| Pesticide Formulations | Emulsifiable concentrate (EC), microemulsion (ME), emulsion in water (EW) preparation | Evenly disperses pesticide technical materials in water to form a stable emulsion, improving spray liquid spreadability and control efficacy |
| Coatings and Inks | Water-based coating dispersion, water-based ink preparation | Promotes uniform dispersion of pigments and fillers, improves storage stability and application leveling |
MOA-5/AEO-5, as a general-purpose nonionic surfactant, has an HLB value in the medium range (approximately 10-11), possessing both hydrophilic and lipophilic characteristics, making it particularly suitable as a primary or secondary emulsifier in formulations. In formulation design, it is recommended:
