Description

23-(4-Nonylphenoxy)-3,6,9,12,15,18,21-Heptaoxatricosyl Hydrogen Sulphate is a specialized non-ionic surfactant derivative, specifically an ethoxylated nonylphenol ether sulfate. This compound is engineered to deliver superior wetting, emulsifying, and dispersing properties in demanding industrial formulations. It is a critical performance additive for manufacturers in sectors requiring precise surface activity and compatibility with aqueous systems, such as agrochemicals, coatings, and textile processing.

Application

• Agrochemical Formulations: Acts as a key wetting agent and emulsifier in pesticides, herbicides, and fungicides, enhancing spray coverage and active ingredient dispersion.
• Industrial & Institutional Cleaners: Provides powerful detergency and foam control in heavy-duty cleaning products for hard surfaces and equipment.
• Textile Processing: Used as a scouring, leveling, and wetting agent in dyeing and finishing operations to ensure uniform color application.
• Coatings & Inks: Functions as a dispersant and flow control additive in water-based paints, inks, and coatings to improve stability and application properties.
• Metal Working Fluids: Serves as an emulsifier and corrosion inhibitor in coolants and cutting fluids.
• Polymerization: Can be employed as an emulsifier in emulsion polymerization processes for synthetic rubbers and plastics.
• Leather Processing: Used in tanning and fatliquoring processes to improve penetration and softening of leather.
