Description

Diammonium Dodecyl-4-(4-Sulphonatophenoxy)Benzenesulphonate is a specialized anionic surfactant characterized by its unique dual-sulfonate structure. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding formulations. It is primarily utilized by manufacturers in the agrochemical, industrial cleaning, and textile processing sectors where high-performance surface activity is required.

Application

• Agrochemical Formulations: Acts as a key wetting and dispersing agent in suspension concentrates (SC) and wettable powders (WP) for pesticides and herbicides.
• Industrial & Institutional (I&I) Cleaners: Provides superior detergency and foam control in heavy-duty alkaline and acidic cleaning products.
• Textile Processing: Used as a levelling agent, dispersant for dyes, and in scouring and bleaching baths.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid in water-based systems to improve color development and stability.
• Oilfield Chemicals: Employed in drilling mud formulations and as a surfactant in enhanced oil recovery (EOR) processes.
• Construction Additives: Enhances the workability and dispersion of additives in cement and concrete formulations.

Quality Control

Our production of Diammonium Dodecyl-4-(4-Sulphonatophenoxy)Benzenesulphonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, impurity profile, and physical property verification, to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, identity, and key specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
