Agricultural Emulsifier 600 (tristyrylphenol polyoxyethylene ether, CAS No.: 99734-09-5) is a nonionic surfactant. It appears as a light yellow to brownish yellow viscous liquid that is flowable, with increasing viscosity as temperature decreases. Its molecular structure features tristyrylphenol as the hydrophobic group, with polyoxyethylene chains providing hydrophilicity. This unique structure gives it excellent emulsifying ability in various oil phases and solvent systems, resulting in stable emulsions that are not prone to separation.
The outstanding advantage of this product lies in its broad chemical stability—it maintains performance without degradation over a wide pH range and in high-hardness water, which is particularly crucial in complex pesticide formulations. Additionally, Agricultural Emulsifier 600 can be flexibly compounded with anionic, cationic, and other nonionic surfactants to achieve synergistic effects, offering formulation engineers great design freedom. Its excellent wetting and spreading properties effectively reduce surface tension, promoting the adhesion of the spray liquid to target surfaces.

Pesticide Emulsifier (Main Application): Suitable for preparing emulsifiable concentrates (EC), oil-in-water emulsions (EW), microemulsions (ME), and other formulations. It can be used as the primary or auxiliary emulsifier, significantly improving the dispersibility of pesticide active ingredients and emulsion stability, thereby prolonging the efficacy period.
Textile Printing and Dyeing Auxiliaries: Used as leveling agents, penetrants, and components of finishing auxiliaries to improve the penetration and migration of dyes on fabrics such as cotton and polyester, preventing color spots and dyeing defects.
Industrial Cleaners: With excellent emulsifying and penetrating abilities, it can be used to formulate metal degreasers and multi-purpose cleaners, effectively removing mineral oils, animal and vegetable oils, and other soils.
Metalworking Fluid Components: In cutting fluids and grinding fluids, it acts as an emulsifier and lubricant, enhancing cooling performance, while also helping to inhibit bacterial growth and extend the service life of the working fluid.
It is recommended to determine the optimal dosage through experiments in specific formulations. When used as the primary emulsifier, the dosage depends on the type of oil phase and the target formulation. When compounded with anionic surfactants (such as the Agricultural Emulsifier 500 series), better synergistic emulsifying effects can be achieved.
