Description

Calcium 2-Methylnaphthalenesulphonate is an organosulfonate salt derived from 2-methylnaphthalene. This compound is valued for its surfactant and dispersant properties, making it a functional additive in various industrial formulations. It is primarily utilized in sectors requiring effective wetting, emulsification, or particle suspension. Global industries such as agrochemicals, construction materials, and specialty chemical manufacturing rely on this material for process enhancement and product performance.

Application

• Agrochemical Formulations: Acts as a wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides.
• Construction Chemicals: Used as a plasticizer and water-reducing agent in concrete admixtures and cement grinding aids.
• Industrial Cleaning: Serves as a key surfactant in heavy-duty industrial and institutional cleaning products.
• Textile Processing: Functions as a levelling agent and dispersant in dyeing and printing processes.
• Oilfield Chemicals: Employed in drilling mud formulations and as a surfactant for enhanced oil recovery.
• Pigment & Dye Dispersions: Provides stabilization and prevents agglomeration in colorant preparations for paints, inks, and plastics.
• Rubber & Polymer Industry: Used as an emulsifier in emulsion polymerization and as a processing aid.

Quality Control

Our Calcium 2-Methylnaphthalenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as assay, moisture content, and impurity profiles are monitored. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

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); therefore, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity.
