Description

Sodium p-Decylbenzenesulphonate is a high-purity anionic surfactant belonging to the linear alkylbenzene sulfonate (LAS) family. This compound is valued for its excellent wetting, foaming, and emulsifying properties, making it a critical performance ingredient in demanding formulations. It is primarily needed by manufacturers in the detergent, industrial cleaning, textile processing, and agrochemical industries for its reliable and consistent surfactant action.

Application

• Detergent & Cleaning Formulations: A key anionic surfactant in industrial and institutional (I&I) cleaners, dishwashing liquids, and hard surface cleaners for its powerful degreasing and foaming characteristics.
• Textile Processing: Used as a wetting agent, scouring aid, and emulsifier in the preparation, dyeing, and finishing of textiles.
• Agrochemicals: Functions as an effective wetting and dispersing agent in pesticide and herbicide formulations to improve spray coverage and efficacy.
• Emulsion Polymerization: Serves as an emulsifier and stabilizer in the production of synthetic rubbers, plastics, and latex paints.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery processes as a surfactant to modify interfacial tension.
• Personal Care: Used in select rinse-off products where its specific surfactant properties are required, subject to grade and purity specifications.

Quality Control

Our Sodium p-Decylbenzenesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, active matter content, and impurity profiles. Certificates of Analysis (COA) documenting key parameters are provided to guarantee supply consistency and performance reliability for your formulations.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture which may lead to caking or performance variation.
