Compared to traditional anionic emulsifiers (such as fatty acid soaps and sulfonates), although Emulsifier FM is produced from the reaction of fatty acids and organic amines, it exhibits stronger nonionic characteristics in practical application systems. Its HLB value is approximately 12, and its cloud point is >100°C, which gives it better chemical stability under high-temperature conditions than conventional nonionic emulsifiers (such as fatty alcohol polyoxyethylene ether series), making it less prone to precipitation and failure due to excessive temperature. Compared to common Span/Tween emulsifier combinations, Emulsifier FM alone can achieve stable oil-in-water (O/W) emulsions, simplifying the formulation screening process.
Compared to pure cationic surfactants, Emulsifier FM is milder. Although its molecular structure contains protonatable nitrogen atoms, its overall irritation is much lower than that of conventional quaternary ammonium salt cationic emulsifiers, and it also has a certain tendency for rust protection. In metalworking fluids, it not only serves as an efficient emulsifier but also synergistically enhances rust protection—a combination that is difficult to achieve with traditional anionic or nonionic emulsifiers. In the textile field, it imparts excellent soft hand feel to fibers while eliminating static buildup, enhancing wearing comfort. This functional combination performs exceptionally well compared to similar competing products.
Based on real data from the Guo Li Chemical product database, the key technical indicators of Emulsifier FM are benchmarked against competitors as follows:
| Core Advantage Indicator | Emulsifier FM (Guo Li Chemical) | Similar Competitors (e.g., General Nonionic Emulsifier) | Advantage Explanation |
|---|---|---|---|
| Active Content | ≥99% | Typically 95% or industrial grade | High purity means fewer side reactions and more stable emulsification performance |
| HLB Value | Approximately 12 | Varies by type, requires compounding | An HLB value of 12 is very suitable for preparing O/W emulsions and can function alone |
| Cloud Point | >100°C | Nonylphenol polyoxyethylene ether etc. are often at 60–80°C | Extremely high temperature tolerance, especially suitable for high-temperature cutting, cleaning, and other working conditions |
| Alkali Resistance Stability | Good | Ordinary esters are prone to hydrolysis | Maintains structural stability in alkaline formulations, wider application range |
| Foam Characteristics | Low foam | Many similar products are medium to high foam | Obvious advantage in circulating cleaning and high-speed metalworking, reducing the amount of defoamer needed |
| Multifunctionality | Emulsification + Rust protection + Softening + Antistatic | Relatively single function | One agent with multiple functions, can simplify formulations and reduce overall production costs |
If your application scenario requires a product that maintains efficient emulsification in acidic, alkaline, and hard water environments while also providing foam control, Emulsifier FM is an ideal choice. It is particularly suitable for building long-lasting emulsification and rust protection systems in metalworking fluids, serving as a softening and antistatic component in textile auxiliaries, and for rapidly removing grease without foam residue in industrial cleaning.
