Description

Sodium Diisobutylnaphthalenesulphonate is a high-purity anionic surfactant and dispersing agent derived from naphthalene. This compound is valued for its excellent wetting, emulsifying, and solubilizing properties in demanding industrial formulations. It is essential for manufacturers in sectors requiring stable colloidal systems and effective surface tension reduction.

Application

• Primary dispersing agent for pigments, dyes, and carbon black in coatings and inks.
• Key wetting and emulsifying agent in agrochemical formulations for pesticides and herbicides.
• Effective solubilizer and stabilizer in industrial cleaning and degreasing products.
• Used as a latex stabilizer and particle suspension aid in polymer emulsion production.
• Component in concrete admixtures to improve workability and reduce water content.
• Processing aid in the textile industry for dye leveling and fiber treatment.
• Additive in oilfield chemicals for drilling mud and enhanced oil recovery formulations.
