Description

Disodium Diisononylnaphthalenedisulphonate is a high-performance anionic surfactant and hydrotrope. This compound is valued for its excellent solubilizing and dispersing properties in aqueous systems, particularly for hydrophobic substances. It is primarily utilized in the formulation of industrial and institutional cleaning products, agrochemicals, and various chemical synthesis processes where stable emulsions and microemulsions are required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key hydrotrope and coupling agent in heavy-duty liquid detergents, degreasers, and hard surface cleaners.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates to enhance stability and efficacy.
• Chemical Processing: Serves as a solubilizer and phase transfer catalyst in organic synthesis and polymerization reactions.
• Textile & Leather Auxiliaries: Employed in dyeing and finishing processes to improve dye dispersion and leveling.
• Oilfield Chemicals: Functions as a formulation component in drilling muds and production chemicals for demulsification and dispersion.
• Paint & Coating Additives: Aids in pigment wetting and dispersion in water-based coating systems.

Quality Control

Our Disodium Diisononylnaphthalenedisulphonate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets consistent performance specifications, including active matter content, pH, and solubility. A comprehensive Certificate of Analysis (COA) detailing purity and physical-chemical parameters is provided with every shipment to guarantee reliable quality and batch-to-batch consistency for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
