1. Chemical and Physical Properties

• Chemical Type: It belongs to the category of fatty alcohol polyoxyethylene ethers, non-ionic surfactants specifically designed as high-efficiency emulsifiers for pesticide emulsifiable concentrates (EC) and microemulsions (ME).
• Appearance and Physicochemical Indicators: It appears as a pale yellow to yellow viscous liquid with a density of approximately 0.95~1.05 g/cm³ (at 20℃). The pH value (1% aqueous solution) ranges from 5.0 to 7.0. It is miscible with most organic solvents (e.g., xylene, mineral oil) and water in any proportion.

2. Mechanism of Action

• Synergistic Emulsification and Solubilization: The polyoxyethylene ether segments in the molecule can form hydrogen bonds with the aqueous phase, while the fatty alcohol segments are compatible with the oil phase. By reducing the oil-water interfacial tension, pesticide technical materials can be rapidly emulsified and solubilized in the oil-water system to form a stable emulsion or microemulsion.
• System Stability Construction: Through steric hindrance effects, a protective film is formed on the surface of emulsified particles to prevent particle aggregation, maintaining the formulation from stratification or emulsion breaking during storage and transportation.

3. Key Application Technical Points

• Addition Amount: Generally, it accounts for 5%~10% of the pesticide formulation mass (the specific amount needs to be adjusted according to the characteristics of the technical material). For example, in beta-cypermethrin 5% EC, the addition amount is approximately 7%.
• Addition Method: During the emulsification and mixing stage of emulsifiable concentrates/microemulsions, it is uniformly mixed with technical materials, solvents and other components to ensure uniform distribution in the formulation.
• Compatibility: It can be used synergistically with most anionic emulsifiers (e.g., alkylbenzenesulfonates) and non-ionic dispersants. Long-term contact with strongly acidic or strongly alkaline adjuvants should be avoided.

4. Performance Advantages and Market Value

• High-Efficiency Emulsification and Solubilization: In EC/ME formulations of hard-to-emulsify technical materials such as beta-cypermethrin and fenvalerate, after adding TERWET 3001, the emulsification time can be controlled within 5 minutes, and the emulsion stability (30 days of normal temperature storage) is ≥99%. This is better than traditional emulsifiers (which usually have an emulsification time of 10~15 minutes and an emulsion stability of ≤95%).
• Outstanding Cost-Effectiveness: Compared with imported similar emulsifiers (such as a certain brand's Tween series), it has a 12%~20% lower procurement cost. Meanwhile, its high emulsification efficiency can reduce solvent usage by 5%~10%, effectively reducing the formulation cost of pesticide preparation enterprises.
• Excellent Storage Stability: After 14 days of high-temperature storage at 54℃, the emulsification performance attenuation of formulations containing TERWET 3001 is ≤4%, which can meet the long-term storage and transportation requirements of major global agricultural markets.
