Description

Benzenesulfonic Acid, Mono-C15-30-Branched Alkyl And Di-C11-13-Branched And Linear Alkyl Derivs., Sodium Salts, Overbased is a specialized, high-performance surfactant and detergent additive derived from a complex alkylbenzene sulfonate structure. This compound is engineered to provide exceptional detergency, dispersancy, and acid-neutralizing capacity in demanding formulations. It is a critical component for industrial and institutional cleaning products, lubricant additives, and emulsion polymerization processes where robust performance under harsh conditions is required.

Application

• Industrial & Institutional (I&I) Cleaners and Detergents: Acts as a primary surfactant and detergent builder in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Lubricant and Fuel Additives: Functions as a detergent and dispersant additive in engine oils and industrial lubricants to control deposits and neutralize acidic combustion by-products.
• Emulsion Polymerization: Serves as an effective surfactant and stabilizer in the production of synthetic rubbers (e.g., SBR, NBR) and plastic dispersions like ABS and SAN.
• Textile and Leather Processing: Used as a wetting agent, emulsifier, and scouring aid in fiber treatment and leather tanning processes.
• Agricultural Formulations: Employed as an emulsifier and dispersant in pesticide and herbicide concentrates to enhance stability and application performance.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as a surfactant for demulsification and corrosion inhibition.

Quality Control

Our production of Overbased Sodium Alkylbenzene Sulfonate adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as Total Base Number (TBN), sulfonate content, viscosity, and alkalinity are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing assay, physical properties, and performance indicators is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperature (15-25°C/59-77°F). Keep away from strong oxidizing agents and heat sources. Due to its alkaline nature and potential sensitivity to atmospheric carbon dioxide, containers should be kept sealed when not in use.
