Description

Ammonium Diheptylnaphthalenesulphonate is an anionic surfactant belonging to the alkylnaphthalene sulfonate class. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It is primarily utilized in sectors requiring high-performance surface-active agents, such as agrochemicals, coatings, and textile processing.

Application

• Agrochemical Formulations: Acts as a key wetting and dispersing agent in pesticides, herbicides, and fungicides to enhance spray coverage and active ingredient stability.
• Industrial Cleaners & Detergents: Used in heavy-duty cleaning products for its ability to emulsify oils and greases in alkaline environments.
• Coatings & Inks: Serves as a pigment dispersant and grinding aid to improve color development and prevent settling in paint and ink systems.
• Textile Processing: Employed as a levelling agent and detergent in dyeing and scouring processes for synthetic and natural fibers.
• Oilfield Chemicals: Functions as an additive in drilling muds and completion fluids for its surfactant properties.
• Rubber & Polymer Industry: Used as an emulsifier in emulsion polymerization processes for synthetic rubber and latex production.
• Leather Processing: Aids in the wetting and penetration of chemicals during tanning and dyeing operations.

Quality Control

Our Ammonium Diheptylnaphthalenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets high-purity standards for industrial applications. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and ionic composition is provided with every shipment to guarantee supply reliability and product traceability.

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 may affect product performance.
