Description

Butylnaphtalenesulfonic Acid Sodium Salt is a versatile anionic surfactant and chemical intermediate derived from naphthalene. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It serves as a critical component for manufacturers in the agrochemical, textile, and construction chemical industries seeking reliable performance additives.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates.
• Textile Processing: Used as a leveling agent, dispersant for dyes, and wetting agent in various dyeing and finishing operations.
• Construction Chemicals: Functions as a plasticizer and water-reducing agent in concrete admixtures and cement formulations.
• Industrial Cleaners & Detergents: Provides effective surface wetting and soil dispersion in heavy-duty cleaning products.
• Pigment & Dye Manufacturing: Serves as a grinding aid and dispersant to stabilize pigment suspensions and prevent agglomeration.
• Oilfield Chemicals: Utilized in drilling mud formulations and as an additive for enhanced oil recovery processes.
• Leather Processing: Employed as a wetting and penetrating agent in tanning and dyeing processes.
• Paper & Pulp Industry: Acts as a dispersant and de-foaming agent in paper coating and pulp processing.

Quality Control

Our Butylnaphtalenesulfonic Acid Sodium Salt is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, moisture content, and pH. Our quality commitment aligns with ISO 9001 standards, and we can support compliance documentation for REACH and other global regulatory frameworks as required.

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 to prevent absorption of atmospheric moisture, which can affect product performance and flow characteristics.
