Emulsifier FM, chemically known as triethanolamine monooleate, is a nonionic surfactant appearing as an amber to brown viscous liquid. Its molecular structure endows the product with excellent emulsifying, wetting, and dispersing functions, particularly capable of rapidly forming stable and fine oil-in-water (O/W) emulsions with mineral oils, vegetable oils, and various organic solvents. Additionally, this product exhibits good tolerance to acidic, alkaline, and hard water environments, and can be compounded with anionic, cationic, and amphoteric surfactants, offering strong formulation adaptability.
In industrial applications, Emulsifier FM, with its high emulsifying power and multifunctional synergistic properties, has become an irreplaceable key component in many formulation systems. It also possesses auxiliary functions such as wetting, dispersing, and antistatic properties, reducing the need for auxiliary additives in composite formulations and optimizing overall costs. Meanwhile, it provides a certain tendency for rust protection on metal substrates and imparts a soft hand feel to fibers in textile processing.
| Application Industry | Specific Process/Product | Role of Emulsifier FM |
|---|---|---|
| Metalworking & Rust Prevention | Emulsified cutting fluids, grinding fluids, rust inhibitors | As a core emulsifier, forming stable emulsions with base oils, significantly enhancing lubrication and rust prevention performance, extending tool life |
| Cosmetics & Personal Care | Creams, lotions, shampoos, etc. | A mild O/W emulsifier and emollient, helping to build fine cream structures, improving spreadability and post-wash skin feel, with moisturizing and thickening effects |
| Textile Auxiliaries | Softening agents, antistatic agents | Improving fiber surface hydrophilicity and smoothness, imparting a soft and smooth hand feel to fabrics, eliminating static buildup during synthetic fiber processing |
| Pesticide Formulations | Emulsifiable concentrates, oil-in-water emulsions, microemulsions | Efficiently emulsifying pesticide active ingredients, promoting spontaneous formation of uniform emulsions upon dilution, enhancing droplet spreading on leaf surfaces, improving field efficacy |
| Industrial Cleaning | Industrial degreasers, hard surface cleaners | Enhancing emulsification and detachment of oils and grease, accelerating oil removal and suspension, delaying soil redeposition, significantly improving cleaning efficiency |
| Emulsion Polymerization | Polymerization of monomers such as acrylates, styrene-butadiene rubber | As a primary emulsifier providing a stable micellar environment, stabilizing monomer droplets, precisely controlling latex particle size, ensuring smooth polymerization reactions |
| Inks & Coatings | Water-based inks, water-based coatings | Improving wetting and dispersion of pigments and fillers, preventing sedimentation and flocculation, adjusting system viscosity, enhancing leveling and coating gloss |
As a versatile nonionic emulsifier, Emulsifier FM dosage should be determined based on the oil phase type and required HLB value in the formulation. In metalworking fluid formulations, it is often compounded with anionic emulsifiers to enhance emulsion stability; in personal care products, its mildness makes it suitable for sensitive skin formulations; in pesticide emulsifiable concentrates, it can be used synergistically with nonionic emulsifier blends to improve automatic dispersibility. The product is stable under storage conditions at 5～35°C. If thickening occurs at low temperatures, it can be warmed to room temperature and stirred evenly before use.
