Agricultural Emulsifier 600 (tristyrylphenol polyoxyethylene ether) is primarily used in four major industries: pesticide formulations, textile printing and dyeing, industrial cleaning, and metalworking, serving as a high-performance nonionic surfactant with core functions such as emulsifying, dispersing, and wetting.
Detailed Description
Agricultural Emulsifier 600 is a polyoxyethylene ether nonionic surfactant with tristyrylphenol as the hydrophobic group. Its unique molecular structure endows it with excellent emulsifying, wetting, and dispersing capabilities. The product appears as a viscous liquid ranging from light yellow to brownish yellow, with outstanding resistance to acids, alkalis, and hard water. It maintains stable performance across a wide pH range and in high-hardness water conditions, and can be flexibly compounded with anionic, cationic, and other nonionic surfactants for synergistic effects.
With its exceptional overall performance, Agricultural Emulsifier 600 has expanded from its initial use in pesticide emulsification to various industrial auxiliaries. Its core advantage lies in its remarkable emulsifying ability for multiple oil phases and solvent systems, forming stable, non-stratifying emulsions while effectively reducing surface tension, promoting the wetting and spreading of the liquid or working solution on target surfaces.
Detailed Industry Applications and Processes
1. Pesticide Formulation Industry
Agricultural Emulsifier 600 is an important emulsifier variety in the pesticide formulation field, widely used in the following dosage form processes:
- Emulsifiable Concentrate (EC): As the primary or auxiliary emulsifier, it rapidly emulsifies the mixture of pesticide active ingredient and organic solvent into a stable emulsion, ensuring uniform dispersion of the diluted liquid during field application.
- Emulsion in Water (EW): Provides a stable interfacial film in the oil-water system, preventing oil droplet coalescence and ensuring long-term storage stability of the formulation.
- Microemulsion (ME): Combined with auxiliary emulsifiers, it reduces the oil-water interfacial tension to ultra-low levels, forming a thermodynamically stable transparent or translucent dispersion system.
Using Agricultural Emulsifier 600 significantly improves the dispersibility and emulsion stability of pesticide active ingredients, enhancing the duration of efficacy.
2. Textile Printing and Dyeing Industry
In textile printing and dyeing processes, Agricultural Emulsifier 600 is used as a multifunctional auxiliary in:
- Leveling Process: Acts as a leveling agent to improve dye penetration and migration on fabrics, effectively preventing color spots and dyeing defects.
- Dispersion Process: Serves as a dispersant to help dye particles remain uniformly suspended in the dye bath, ensuring even and consistent coloration.
- Finishing Process: As a component of finishing auxiliaries, it enhances fabric properties such as hydrophilicity and softness for better wearability.
Suitable for processing various fibers such as cotton and polyester.
3. Industrial Cleaning Industry
With outstanding emulsifying and penetrating capabilities, Agricultural Emulsifier 600 is mainly used in industrial cleaning for:
- Metal Degreaser: Formulates efficient metal surface degreasing cleaning solutions, rapidly emulsifying and removing mineral oil, rust-preventive oil, and other residues from metal processing.
- Multi-purpose Hard Surface Cleaner: Enhances the solubilization and dispersion of animal and vegetable oils and heavy grease in cleaning solutions, widely used in heavy-duty cleaning scenarios such as vehicles and mechanical equipment.
4. Metalworking Fluid Industry
In metalworking fluid systems, Agricultural Emulsifier 600 is used as a key emulsifying component in:
- Cutting Fluid: Provides a stable oil-water emulsifying system, offering both lubrication and cooling functions to reduce cutting zone temperature and friction.
- Grinding Fluid: Ensures heat dissipation and chip removal performance during grinding, while inhibiting bacterial growth to prolong the service life of the working fluid.
Usage Precautions
Agricultural Emulsifier 600 is irritating to skin (H315) and eyes (H319), and may cause respiratory irritation (H335). During operation, chemical safety goggles, protective gloves, and protective clothing should be worn. The product is harmful to aquatic life with long-lasting effects (H412) and must not be discharged into water bodies. Waste disposal should be entrusted to qualified professional institutions for harmless treatment. Storage temperature is recommended to be controlled at 5–35°C, with the container kept tightly closed, away from heat sources and incompatible substances.
