Description

Diammonium Diisononylnaphthalenedisulphonate is a high-purity, water-soluble anionic surfactant derived from naphthalene. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It is a critical component for manufacturers in the agrochemical, construction, and textile industries seeking reliable performance and batch-to-batch consistency.

Application

• Primary dispersant and wetting agent in agricultural formulations such as suspension concentrates (SC) and wettable powders (WP).
• Key ingredient in construction chemicals, including concrete admixtures and pigment dispersions for coatings.
• Effective emulsifier and stabilizer in the production of industrial and institutional (I&I) cleaning products.
• Dispersing agent for dyes and pigments in the textile and leather processing industries.
• Used in the formulation of oilfield chemicals for drilling muds and enhanced oil recovery processes.
• Component in paper and pulp processing aids for improved fiber dispersion and de-inking.
