Agricultural Emulsifier 600 is mainly applied in four major industries: pesticide formulations, textile printing and dyeing, industrial cleaning, and metalworking.

Detailed Description

Agricultural Emulsifier 600 (tristyrylphenol polyoxyethylene ether, CAS: 99734-09-5) is a high-performance nonionic surfactant that plays a key role in various industrial fields due to its excellent emulsifying, wetting, and dispersing capabilities. Its unique molecular structure endows the product with superior resistance to acid, alkali, and hard water, allowing flexible compounding with anionic, cationic, and other nonionic surfactants for synergistic effects.

In the field of pesticide formulations, this product is a core emulsifier component for emulsifiable concentrates (EC), emulsions in water (EW), microemulsions (ME), etc., significantly improving the dispersibility of technical pesticides and emulsion stability; in textile printing and dyeing, it acts as a leveling agent and dispersant to effectively prevent color spots and dyeing defects; in industrial cleaning, its strong emulsifying and penetrating power is suitable for metal degreaser formulations; in metalworking fluids, it plays multiple roles including emulsification, lubrication, and cooling.

Application Fields

Industry	Specific Process/Formulation	Functional Role
Pesticide Formulations	Emulsifiable Concentrate (EC), Emulsion in Water (EW), Microemulsion (ME)	Primary or auxiliary emulsifier, improving dispersibility and emulsion stability
