600P-85% tristyrylphenol polyoxyethylene ether phosphate is a high-performance anionic surfactant synthesized by phosphating modification of tristyrylphenol polyoxyethylene ether as the backbone. Its unique molecular structure—the synergistic effect of a multi-aromatic ring lipophilic backbone and polyoxyethylene chains—endows it with dual characteristics of both nonionic and anionic surfactants, exhibiting excellent interfacial control capability in complex industrial systems. The product has an active matter content of up to 85% and outstanding electrolyte tolerance, maintaining stable activity in high-salt, high-acid, and high-alkali systems without precipitation or deactivation.
In practical applications, this product, with its excellent emulsifying and dispersing abilities, good wetting and spreading properties, as well as low-foaming and foam-suppressing characteristics, can significantly improve the long-term stability and usage efficiency of formulated preparations. Moreover, it exhibits good compatibility and synergy with nonionic, anionic, cationic, and amphoteric surfactants, offering a wide range of formulation adaptability.
| Application Industry | Specific Process/Formulation | Functional Role |
|---|---|---|
| Pesticide Formulations | Emulsifiable Concentrate (EC), Emulsion in Water (EW), Microemulsion (ME), Suspension Concentrate (SC), Oil Dispersion (OD) | Highly effective emulsifier and dispersant, enhancing formulation long-term stability and efficacy |
| Textile Printing and Dyeing | High-temperature leveling, scouring, and dispersing processes | Leveling agent, scouring agent, and dispersant, helping uniform dye uptake, preventing color spots, and improving fabric hand feel and color fastness |
| Metalworking and Industrial Cleaning | Metal cutting fluids, wire drawing fluids, hard surface cleaning | Synergistic emulsification, lubrication, and rust prevention; enhanced detergency and dirt dispersion |
| Water-based Coatings and Inks | Color paste preparation, pigment dispersion processes | High-efficiency wetting and dispersing agent for pigments/fillers, preventing floating, flooding, and pigment settling, improving color paste storage stability and color development |
| Emulsion Polymerization | Vinyl acetate, acrylate, and other systems | Emulsifier and stabilizer, providing fine and stable micelles, controlling particle size distribution, improving overall performance of polymer emulsion |
| Oilfield Chemicals | Drilling fluids, enhanced oil recovery, crude oil dehydration | Emulsifying, dispersing, and wetting functions; tolerant to downhole high temperature and high salinity; improving oil recovery and demulsification efficiency |
| Industrial Cleaning | Cleaning of metal parts, glass, and other hard surfaces | Surfactant component, effectively removing oil and grease, with low-foaming and anti-corrosion properties |
It is recommended to add 600P-85% during the acid or base adjustment stage of formulation development, with thorough stirring to ensure uniformity. Based on the specific application system and performance requirements, the optimal addition ratio should be determined through gradient experiments, and the synergistic ratio with other additives should be optimized. Due to the high active matter content (85%) of the product, the actual dosage is usually lower than that of common phosphate ester surfactants, offering good cost-effectiveness.
