1. For Food Emulsification & Stabilization: Polysorbate 20 (Tween 20, CAS 9005-64-5) is a food-grade nonionic emulsifier (E432) that stabilizes oil-in-water emulsions in ice cream, beverages, sauces and bakery products, improving texture, shelf stability and consistency at low dosage.
2. For Agrochemical Formulations: As a high-HLB emulsifier and wetting agent, Polysorbate 20 improves the stability and spreading of emulsifiable concentrates, suspension concentrates and adjuvants in pesticide and crop-protection formulations.
3. For Industrial Emulsions & Coatings: Polysorbate 20 acts as an emulsifier and wetting agent in emulsion polymerization, water-based paints, inks and adhesives, providing stable particle size and improved pigment dispersion and film performance.
4. For Textile & Leather Processing: As a nonionic wetting and scouring auxiliary, Polysorbate 20 improves penetration and levelness in textile processing and leather treatment, supporting efficient wetting, degreasing and finishing operations.
5. For Industrial Cleaning & Detergent Formulations: Polysorbate 20 enhances wetting, emulsifying and soil-removal performance in industrial cleaners, laundry additives and degreasing formulations.
6. Consistent Quality For Global Industry: Supplied as a high-purity nonionic surfactant with stable HLB, low odor and consistent quality, Polysorbate 20 gives food, agrochemical, coating, textile and cleaning manufacturers a dependable emulsifier with flexible packaging and stable supply.
