Applications
1. Food Emulsifier (E433) A versatile food-grade emulsifier for ice cream, dressings, bakery and dairy products. Stabilizes oil-in-water emulsions, improves texture and mouthfeel, and prevents separation for consistent product quality in food manufacturing.
2.Cosmetics & Personal Care An effective emulsifier, solubilizer and dispersant in creams, lotions, serums and cleansers. Delivers stable emulsions, improved ingredient delivery and a smooth, non-greasy finish.
3. Agrochemical Formulations Improves emulsification, spreading and penetration of pesticide and plant protection formulations. Enhances active ingredient efficacy and stability for consistent field performance.
4. Industrial Cleaning & Metalworking A wetting and emulsifying agent in industrial cleaners, metalworking fluids and degreasers. Improves soil removal, emulsion stability and surface wetting in demanding industrial processes.
5. Laboratory & Biotechnology A standard nonionic surfactant for cell culture, protein stabilization and biochemical applications. Consistent quality and low impurity profile support reproducible experimental results.
