1. Basic Attributes

• Product Type: High-efficiency anionic-nonionic compounded emulsifying dispersant. Its core components are a compound system of anionic surfactants (presumed to be alkylnaphthalene sulfonate formaldehyde condensate) and nonionic surfactants (presumed to be polyoxyethylene-polyoxypropylene block copolymer), designed for complex formulations with high solid content and high electrolyte concentration.
• Key Technical Indicators: HLB value is approximately 11-13 (suitable for oil-in-water/O/W emulsification and high-solid-content suspension needs), solid content ≥ 45%, pH value (1% aqueous solution) 6.0-8.0. It contains no NP (nonylphenol) or APE (alkylphenol ethoxylate) residues and meets environmental compliance requirements.
• Applicable Systems: Compatible with high-solid-content (≥ 60%) suspension systems, high-electrolyte (e.g., 20% potassium sulfate solution) systems, and medium-to-high viscosity slurries. It has strong tolerance to acidic (pH ≥ 4) and alkaline (pH ≤ 10) environments.

3. Functions and Typical Application Scenarios

• Core Functions:

  1. Efficient Emulsification and Dispersion: Through the synergistic effect of "anionic anchoring + nonionic steric hindrance", high-solid-content solid particles (e.g., pesticide technical materials, industrial pigments) are uniformly dispersed in the water phase to inhibit agglomeration, ensuring no obvious stratification of the suspension after 72 hours of standing.
  2. High Electrolyte Tolerance: Maintains stable emulsification in formulations containing high-concentration electrolytes (e.g., 20% potassium sulfate solution), avoiding particle flocculation caused by electrolyte damage to the electric double layer.
  3. Auxiliary Wetting and Penetration: Reduces the liquid-solid interfacial tension, promoting the rapid penetration of liquid pesticides or cleaning solutions into target surfaces (e.g., crop leaves, oil-stained gaps on metals) to improve application effectiveness.

• Typical Application Fields:

  • Agrochemical Industry: Used in high-solid-content suspension concentrate (SC) and suspo-emulsion (SE) formulations, such as 70% Pyraclostrobin SC and 65% Thiamethoxam SC. The recommended addition amount is 3%-5%, which can maintain the formulation’s suspension rate ≥ 90% and particle size growth ≤ 20% after thermal storage.
  • Industrial Cleaning: Serves as a core additive in metal surface degreasers and heavy oil cleaners. With an addition amount of 2%-4%, it can increase oil-stripping efficiency by over 30% without corroding metal substrates (e.g., carbon steel, aluminum alloy).
  • Emulsion Polymerization: Used in styrene-acrylic emulsion and vinyl acetate emulsion polymerization systems as an emulsifying stabilizer. It controls the latex particle size within 0.1-0.3 μm and improves the film-forming uniformity and adhesion of the emulsion.

4. Usage Specifications and Precautions

• Recommended Addition Amount: 3%-5% in the pesticide field, 2%-4% in the industrial cleaning field, and 1%-3% in the emulsion polymerization field. The specific amount needs to be adjusted according to the formulation’s solid content and electrolyte concentration. Small-scale tests (e.g., 500mL suspension rate test) are recommended to verify the optimal ratio.
• Compatibility: Compatible with most pesticide technical materials (e.g., Pyraclostrobin, Thiamethoxam) and industrial cleaning auxiliaries (e.g., corrosion inhibitors, solvents). Avoid direct mixing with strongly acidic (pH＜4) or strongly alkaline (pH＞12) substances to prevent hydrolysis of compounded components.
• Storage Requirements: Seal and store in a cool, ventilated place (5-35℃), avoiding direct sunlight and high temperatures. The unopened shelf life is 24 months; after opening, use it within 3 months to prevent performance degradation due to moisture absorption or oxidation.
• Safety: Presumed to be low-toxic (acute oral toxicity LD50 (rat) ≥ 2000 mg/kg). Gloves are recommended during operation to avoid prolonged direct skin contact. If it accidentally enters the eyes, rinse immediately with plenty of water.
