Emulsifier FM is a nonionic surfactant with triethanolamine monooleate as its core component, characterized by high-efficiency emulsification, broad compatibility, chemical stability, and multifunctional synergy, maintaining excellent emulsifying performance especially in acidic, alkaline, and hard water environments.
Detailed Description
Emulsifier FM, chemically named triethanolamine monooleate (CAS No.: 2717-15-9), appears as an amber to brown viscous liquid and belongs to the nonionic surfactant category. Its molecular structure combines hydrophilic triethanolamine groups with lipophilic long-chain oleic acid groups, enabling it to rapidly reduce the oil-water interfacial tension for mineral oils, vegetable oils, and various organic solvents, forming stable, fine oil-in-water (O/W) emulsions. In many industrial formulations, it plays a key role in constructing stable emulsification systems.
One of the most prominent features of this product is its broad compatibility. As a nonionic surfactant, it can be freely compounded with anionic, cationic, and amphoteric surfactants, offering great flexibility in formulation. Additionally, its chemical stability is excellent—it remains structurally stable and functionally effective under acidic, alkaline, and high-hardness water conditions, greatly expanding the product's applicable working conditions, especially in industrial scenarios with demanding water quality.
Emulsifier FM also exhibits multifunctional synergy: besides its core emulsifying function, it provides auxiliary effects such as wetting, dispersing, and antistatic properties. In composite formulations, it can effectively reduce the amount of auxiliary additives, optimizing overall costs. Moreover, the product imparts a certain rust prevention tendency to metal substrates and gives fibers a good soft hand feel in textile processing, truly achieving "one agent, multiple functions".

Application Suggestions
Based on the core characteristics of Emulsifier FM, the following application scenarios and reference directions are recommended:
- Metalworking Fluids: As the core emulsifier for emulsified cutting fluids and grinding fluids, it is recommended to be used with base oils, while leveraging its rust prevention synergy to extend tool life.
- Personal Care Products: As a mild O/W emulsifier and emollient in creams, lotions, and shampoos, it helps build a fine cream structure, improving spreadability and post-wash skin feel.
- Textile Auxiliaries: Used to formulate softeners and antistatic agents, effectively eliminating static buildup during synthetic fiber processing and imparting a soft, smooth hand feel to fabrics.
- Pesticide Formulations: Suitable for emulsifiable concentrates and oil-in-water emulsions, promoting spontaneous formation of uniform emulsions when pesticide active ingredients are diluted, enhancing field application efficacy.
- Industrial Cleaning: In degreasers and hard surface cleaners, it enhances the emulsifying and stripping ability of oils and greases, retarding soil redeposition.
- Emulsion Polymerization: Used as the main emulsifier in emulsion polymerization of monomers such as acrylates, providing a stable micellar environment and controlling latex particle size.
- Inks and Coatings: Improves pigment wetting and dispersion, adjusting system emulsion stability and film-forming properties.
Precautions
- Skin Sensitization Risk: This product is classified under GHS as Skin Sensitization Category 1 (H317), may cause allergic skin reactions. Must wear impermeable gloves (e.g., nitrile rubber gloves) and protective clothing during operation, avoid direct skin contact.
- Eye Protection: This product may cause serious eye irritation. Wear protective goggles during operation. If accidentally gets into eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical attention.
- Storage Conditions: Keep container tightly closed. Store in a cool, dry, well-ventilated warehouse, temperature controlled at 5~35°C, away from heat sources, ignition sources, and direct sunlight.
- Ventilation Requirements: Use in well-ventilated areas, avoid inhalation of vapors or mists. Thoroughly wash exposed skin after handling.
- Spill Handling: Small spills: absorb with inert absorbent materials (e.g., sand, vermiculite) and dispose of as hazardous waste. Large spills: contain with dikes to control spread, prevent entry into sewers and surface waters.
