Description

Sodium Bis(Dinonylphenyl) Sulphate is a specialized anionic surfactant and emulsifying agent with a high molecular weight branched alkylaryl structure. This compound is valued for its exceptional stability and effectiveness in demanding formulations, particularly where compatibility with electrolytes and high temperatures is required. It serves as a critical performance additive for industrial manufacturers in sectors such as polymer synthesis, agrochemicals, and specialty coatings, where it functions as an emulsifier, dispersant, and polymerization aid.

Application

• Primary emulsifier and stabilizer in the emulsion polymerization of styrene-butadiene rubber (SBR), acrylics, and vinyl acetate.
• Key component in the formulation of agricultural chemicals, including emulsifiable concentrates (ECs) and suspension concentrates (SCs), for improved stability and sprayability.
• Dispersing agent and grinding aid in the production of pigments, dyes, and ceramic powders.
• Emulsifier for industrial and institutional (I&I) cleaning products and degreasers.
• Additive in textile processing auxiliaries and leather treatment chemicals.
• Stabilizer and co-emulsifier in the manufacture of synthetic latexes for coatings, adhesives, and sealants.
• Used in oilfield chemicals as a component in drilling muds and emulsion breakers.

Quality Control

Our Sodium Bis(Dinonylphenyl) Sulphate is manufactured under a strict quality management system. Each batch is analyzed to ensure consistent composition, activity, and performance. Key parameters including assay, moisture content, and ionic character are verified. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your specifications.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
