1. Basic Attributes

• Product Name: ECOTERIC T85 (Common Trade Name: Tween 85; Chemical Name: Polyoxyethylene Sorbitan Trioleate)
• CAS Number: 9005-70-3
• Molecular Structure: With sorbitan as the core, it connects 3 oleic acid chains (hydrophobic end) and 20 ethylene oxide units (hydrophilic end) through etherification. Its HLB value is approximately 11.0, classifying it as an O/W (oil-in-water) nonionic surfactant.
• Implementation Standards: Complies with multi-field compliance requirements, including food grade (GB 29221), industrial grade (HG/T 4779), and cosmetic grade (INCI standard). Products of corresponding grades can be selected based on application scenarios.

3. Functions and Typical Application Scenarios

• Core Functions:

  1. Emulsification: Reduces the oil-water interfacial tension, uniformly disperses the oil phase (e.g., mineral oil, grease) in the water phase to form a stable emulsion, and prevents stratification.
  2. Wetting and Dispersion: Rapidly reduces the surface tension of solid particles (e.g., pesticide technical materials, pigments), promotes their uniform suspension in liquids, and avoids agglomeration.
  3. Solubilization and Stabilization: Exhibits solubilizing effects on insoluble substances (e.g., food flavors, cosmetic active ingredients) to extend product shelf life.

• Typical Application Fields:

  • Food Industry: Used as an emulsifier (permitted food additive under GB 2760) in ice cream, cream, and non-dairy creamer to improve taste and stability. It can also act as a beverage thickener to prevent pulp sedimentation.
  • Agrochemical Industry: Applied in pesticide emulsifiable concentrates (EC) and suspension concentrates (SC) formulations to enhance the dispersibility of technical materials and the durability of pesticide efficacy. For example, adding 1%-3% to 20% chlorantraniliprole EC can reduce the emulsion particle size to below 5μm.
  • Cosmetics and Daily Chemicals: Used in face creams, shampoos, and body washes as an emulsifying stabilizer and humectant to enhance product skin feel and reduce irritation.
  • Industrial Field: Serves as a dispersant in coatings and inks to prevent pigment sedimentation; acts as a leveling agent in the textile industry to improve the uniformity of dye coloring.

4. Usage Specifications and Precautions

• Recommended Addition Amount: Adjust according to application scenarios. It is usually 0.1%-0.5% in the food field and 1%-5% in the industrial field (e.g., pesticides, coatings). The specific amount needs to be verified through small-scale tests to determine the optimal ratio.
• Compatibility: Can be compounded with anionic, cationic, and other nonionic surfactants without compatibility issues. However, attention should be paid to adjusting the HLB value after compounding to avoid affecting emulsification effects.
• Storage Requirements: Seal and store in a cool, ventilated place (5-35℃), avoid direct sunlight and high temperatures. The shelf life is 24 months; after opening, use as soon as possible to prevent moisture absorption or oxidation.
• Safety: The acute oral toxicity LD50 (rat) of food-grade products is >10000 mg/kg, classified as low-toxicity. For industrial-grade products, direct skin contact should be avoided, and gloves are recommended during operation.
