Agricultural Emulsifier 600 (tristyrylphenol polyoxyethylene ether) is a high-performance nonionic surfactant. Its usage is not a fixed single mode but highly dependent on the function you want to achieve. In the field of pesticide formulations, it is often used as a primary emulsifier or co-emulsifier for preparing emulsifiable concentrates (EC), emulsion in water (EW), and microemulsions (ME). Typically, Agricultural Emulsifier 600 is mixed with technical active ingredients, solvents, or other additives in proportion, stirring to fully dissolve and emulsify the technical active ingredients. Its typical dosage varies depending on the type of technical active ingredient and formulation type, and the optimal ratio is generally determined through orthogonal experiments. In textile printing and dyeing, it is used as a leveling agent, effectively preventing color spots and dye marks; in industrial cleaning, it is used for formulating degreasers due to its strong oil removal capability.
Before use, its physical characteristics must be considered. This product is a light yellow to brownish yellow viscous liquid at room temperature, and its viscosity increases or may even solidify at low temperatures. Therefore, before use in cold seasons or regions, it is recommended to preheat it in an environment of 5–35°C to restore good fluidity for accurate measuring and mixing. When taking it, use clean, dry utensils to avoid introducing moisture and impurities that could affect product performance.
Compounding is key to leveraging the performance of Agricultural Emulsifier 600. It can be flexibly combined with anionic, cationic, and other nonionic surfactants to produce synergistic effects. For example, in pesticide emulsifier formulations, combining it with anionic emulsifiers (such as Agricultural Emulsifier 500#) can significantly enhance the emulsification stability and dispersibility of high-melting-point, difficult-to-emulsify pesticide technical active ingredients. When compounding, it is recommended to add Agricultural Emulsifier 600 and other components one by one into the system under stirring conditions, ensuring uniform mixing to obtain a clear, stable homogeneous product.

Pesticide Emulsifier: Used as a primary emulsifier or co-emulsifier for preparing emulsifiable concentrates, emulsion in water, and microemulsions. For emulsifiable concentrates, generally first dissolve the technical active ingredient in the solvent, then add Agricultural Emulsifier 600 and stir evenly. For emulsion in water and microemulsions, it is usually necessary to slowly add the oil phase containing the emulsifier to water under high-speed shear. The recommended dosage is 3%–15% of the total formulation, subject to determination through experiments.
Textile Printing and Dyeing Auxiliary: Used as a leveling agent or dispersant. It can be added directly to the dye bath, with a recommended dosage of 0.5–2 g\/L based on fabric weight. It promotes dye penetration and migration, reducing dyeing defects on fabrics such as polyester and cotton.
Industrial Cleaning Agent: Used for formulating metal degreasers, etc. Combined with alkaline additives, chelating agents, etc., it can efficiently remove mineral oils and animal and vegetable oils. The recommended addition amount in cleaning agent concentrates is 5%–20%.
Metalworking Fluid: Used as an emulsifying component in cutting fluid and grinding fluid formulations, helping to improve the emulsification and lubrication performance of oil-soluble components. The recommended addition amount is 5%–15% of the total concentrate.
