Description

Ammonium Hydroxydinonylbenzenesulphonate is a specialized anionic surfactant belonging to the alkylbenzenesulfonate class. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It is essential for manufacturers in sectors requiring high-performance surface-active agents, particularly where compatibility with alkaline systems is needed.

Application

This versatile surfactant finds use in a wide range of industrial processes. Key applications include:

• Industrial & Institutional (I&I) Cleaners: As a primary wetting and dispersing agent in heavy-duty alkaline cleaners and degreasers.
• Textile Processing: Utilized in scouring, dyeing, and finishing operations for effective penetration and leveling.
• Agrochemical Formulations: Acts as an emulsifier and dispersant in pesticide and herbicide concentrates.
• Metal Working Fluids: Provides emulsification and surface wetting in cutting, grinding, and drawing fluids.
• Paint & Coatings: Serves as a pigment dispersant and grinding aid to improve color development and stability.
• Oilfield Chemicals: Used in drilling muds and well stimulation fluids for its surfactant properties.
• Leather Processing: Employed in soaking, degreasing, and dyeing stages for uniform processing.
• Paper & Pulp Industry: Functions as a de-inking agent and dispersant in pulp processing.

Quality Control

Our Ammonium Hydroxydinonylbenzenesulphonate is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance and meets specifications for critical parameters such as active matter content, pH, and ionic character. Certificates of Analysis (COA) documenting these results 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
