Description

Ammonium Butylnaphthalenesulphonate is an anionic surfactant and dispersing agent derived from naphthalene. This compound is valued for its excellent wetting, emulsifying, and surface tension reduction properties in aqueous systems. It is primarily utilized in industrial formulations where stable dispersion and penetration are critical, serving sectors such as agrochemicals, textiles, and construction materials.

Application

• Agrochemical Formulations: Acts as a key wetting agent and dispersant in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Textile Processing: Used in dyeing and finishing baths to ensure even dye dispersion and penetration into fibers.
• Construction Chemicals: Employed as a plasticizer and air-entraining agent in cement and concrete admixtures to improve workability.
• Industrial Cleaners: Serves as a surfactant in heavy-duty cleaning and degreasing formulations for machinery and metal surfaces.
• Paper Manufacturing: Functions as a dispersant in pulp processing and coating preparations to enhance uniformity.
• Leather Tanning: Aids in the wetting and penetration of tanning agents into hides.
• Oilfield Chemicals: Utilized in drilling mud formulations and as a component in demulsifiers.
