1. Basic Attributes

• Product Type: Nonionic fatty acid polyoxyethylene ester emulsifying dispersant. Its core component is a polymer of stearic acid and ethylene oxide (EO chain length presumed to be 25-30), belonging to ester-type nonionic surfactants with an HLB value of 13-14, suitable for oil-in-water (O/W) emulsification systems.
• Key Certifications: Contains no NP (nonylphenol) or APE (alkylphenol ethoxylate) residues. Complies with EU REACH Regulation and China’s GB/T 26396-2011 biodegradation standard, with biodegradability ≥90%.
• Applicable Systems: Compatible with neutral to weakly alkaline (pH 6-9) aqueous systems, tolerant to low-concentration electrolytes (e.g., <5% sodium chloride solution), and not suitable for strongly acidic (pH < 4) environments.

2. Core Physicochemical Properties 

3. Functions and Typical Application Scenarios

• Core Functions:

  1. Efficient Emulsification: Forms stable O/W emulsions through the combination of ester-based hydrophobic ends with oil phases and polyoxyethylene chain hydrophilic ends with water phases. The emulsion particle size can be controlled within 1-5 μm, with no stratification after 72 hours of standing.
  2. Dispersion and Solubilization: Exhibits solubilizing effects on poorly soluble substances (e.g., pesticide technical materials, food flavors), improving their solubility and stability in aqueous phases.
  3. Auxiliary Wetting: Reduces liquid-solid interfacial tension, promoting the penetration of liquid pesticides or cleaning solutions into target surfaces (e.g., crop leaves, fabric fibers).

• Typical Application Fields:

  • Agrochemical Industry: Used in emulsifiable concentrates (EC) and emulsions (EW) formulations, such as 20% chlorantraniliprole EC. The recommended addition amount is 5%-8%, which can limit the particle size growth of the emulsion to ≤10% after thermal storage.
  • Emulsion Polymerization: Acts as an emulsifier in styrene-acrylic emulsions and vinyl acetate emulsions. With an addition amount of 2%-4%, it controls the latex particle size within 0.2-0.5 μm and improves the film-forming uniformity of the emulsion.
  • Daily Chemicals and Food Industry: Used in face creams, shampoos (as an emulsifier), and food emulsified flavors (e.g., non-dairy creamer). The addition amount is 0.5%-2%, complying with food-grade (e.g., GB 2760) or cosmetic-grade regulatory requirements.

4. Usage Specifications and Precautions

• Recommended Addition Amount: 5%-8% in the pesticide field, 2%-4% in the emulsion polymerization field, and 0.5%-2% in the daily chemical and food fields. Small-scale tests (e.g., emulsion stability test) are recommended to verify the optimal ratio.
• Compatibility: Can be compounded with most nonionic and anionic surfactants. Avoid long-term contact with strongly acidic substances (pH < 4) to prevent ester bond hydrolysis.
• Storage Requirements: Seal and store in a cool, ventilated place (10-30℃), avoiding direct sunlight and high temperatures. The unopened shelf life is 24 months; after opening, use it within 6 months.
• Safety: Food-grade products have an acute oral toxicity LD50 (rat) > 10,000 mg/kg, classified as low-toxic. For industrial-grade products, gloves are recommended during operation to avoid prolonged skin contact.
