Description

Disodium (Dodecylphenoxy)Benzenedisulphonate is a high-purity anionic surfactant and dispersing agent. This compound is valued for its excellent wetting, emulsifying, and solubilizing properties in aqueous systems. It is a critical component for formulators in the agrochemical, detergent, and industrial cleaning sectors who require reliable performance and batch-to-batch consistency.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide concentrates, wettable powders (WP), and suspension concentrates (SC).
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and hard surface cleaners for its superior detergency.
• Textile Processing: Serves as a scouring agent, dye leveling agent, and dispersant in dye baths to ensure uniform color application.
• Paint & Coating Additives: Functions as a pigment grinding aid and dispersant to improve color development and stability in water-based systems.
• Oilfield Chemicals: Employed in drilling mud formulations and as a component in demulsifiers for crude oil processing.
• Detergent Intermediates: Used in the synthesis of more complex surfactant molecules for household and industrial detergents.

Quality Control

Our Disodium (Dodecylphenoxy)Benzenedisulphonate is manufactured under a strict quality management system. Every batch is analyzed to ensure it meets precise chemical and physical specifications, including identity, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

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.
