Description

Sodium 4-sec-Dodecylbenzenesulphonate is a high-purity anionic surfactant belonging to the linear alkylbenzene sulfonate (LAS) family, valued for its excellent detergency, foaming, and emulsifying properties. This compound is a critical raw material for formulating high-performance cleaning and industrial products where consistent quality and reliable supply are paramount. It is essential for manufacturers in the detergent, personal care, textile, and industrial cleaning sectors seeking effective and versatile surface-active agents.

Application

• Detergent & Cleaner Formulation: A primary surfactant in liquid and powder laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Personal Care Products: Used in shampoos, body washes, and hand soaps for its foaming and cleansing efficacy.
• Textile & Leather Processing: Acts as a wetting agent, emulsifier, and scouring agent in textile pretreatment and leather processing.
• Industrial & Institutional (I&I) Cleaners: Key component in formulations for hard surface cleaners, degreasers, and vehicle wash products.
• Emulsion Polymerization: Serves as an emulsifier and stabilizer in the production of synthetic rubbers, plastics, and latex paints.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance wetting, spreading, and penetration.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery processes as a surfactant.

Quality Control

Our Sodium 4-sec-Dodecylbenzenesulphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active matter content, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture which can lead to caking or performance degradation.
