Description

Sodium 3,6,9,12,15,18,21-Heptaoxatritriacontyl Sulphate is a high-purity, non-ionic surfactant derivative, specifically a sodium sulfate salt of a long-chain polyether alcohol. This compound is engineered to deliver superior wetting, emulsifying, and dispersing properties in complex formulations. It is a critical performance additive for industries requiring precise control over surface tension and interfacial activity, such as advanced material processing, agrochemicals, and specialty coatings.

Application

• Agrochemical Formulations: Acts as a key wetting agent and emulsifier in pesticides, herbicides, and foliar fertilizers to enhance spray coverage and plant uptake.
• Specialty Coatings & Inks: Provides excellent pigment dispersion and stability in high-performance coating systems, printing inks, and dye preparations.
• Material Science & Polymer Processing: Used as a surfactant in emulsion polymerization and as a processing aid to improve the compatibility of fillers and additives.
• Industrial & Institutional Cleaners: Serves as a primary surfactant in hard surface cleaners and degreasers, offering effective detergency and foam control.
• Textile & Leather Processing: Functions as a leveling agent, dye dispersant, and softening auxiliary in textile finishing and leather treatment baths.
• Oilfield Chemicals: Employed in drilling muds and production chemicals as an emulsifier and viscosity modifier.
