Description

21-(4-Nonylphenoxy)-4,7,10,13,16,19-Hexaoxahenicosanoic Acid Sodium Salt is a high-purity, non-ionic surfactant derivative with a polyether chain, valued for its excellent surface-active and emulsifying properties. This compound is critical for formulators requiring precise control over solubility, stability, and interfacial activity in complex systems. It is primarily utilized in advanced industrial applications, including specialty polymer synthesis, agrochemical formulations, and as a key component in research and development for novel materials.

Application

• Polymerization Aid & Emulsifier: Acts as a surfactant and stabilizer in emulsion and suspension polymerization processes for synthetic rubbers, plastics, and resins.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in the production of pesticides, herbicides, and fungicides to enhance efficacy and stability.
• Research & Chemical Synthesis: Serves as a valuable intermediate or building block in organic synthesis and materials science research for creating novel surfactants and functional polymers.
• Industrial Cleaners & Degreasers: A key component in formulating heavy-duty industrial and institutional cleaners due to its ability to emulsify oils and greases.
• Textile & Leather Processing: Functions as a leveling agent, dye dispersant, and softener in textile and leather treatment baths.
• Paint & Coating Additive: Enhances pigment dispersion, wetting, and film formation in water-based paints, coatings, and inks.
