Description

Ammonium Undecylbenzenesulphonate is an anionic surfactant belonging to the alkylbenzenesulfonate class, valued for its excellent wetting, emulsifying, and foaming properties. This compound is particularly significant in formulations requiring stable performance in aqueous systems and compatibility with other ionic species. It is primarily needed by manufacturers in the industrial & institutional cleaning, textile processing, agrochemical, and personal care industries for creating effective detergent and dispersion systems.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty floor cleaners, degreasers, and vehicle wash formulations.
• Textile Processing: Used as a wetting agent and emulsifier in scouring, dyeing, and finishing baths.
• Agrochemical Formulations: Acts as a dispersant and wetting agent in pesticide and herbicide concentrates and emulsifiable concentrates (ECs).
• Personal Care: Employed in select rinse-off products like shampoos and body washes for its cleansing and foaming characteristics.
• Emulsion Polymerization: Serves as an anionic emulsifier in the production of synthetic rubbers, latex paints, and polymer dispersions.
• Metal Working Fluids: Functions as an emulsifier and corrosion inhibitor in coolants and drawing compounds.

Quality Control

Our Ammonium Undecylbenzenesulphonate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with relevant industrial specifications. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and active matter are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
