Description

Sodium Dodecylbenzenesulphonate (SDBS) is a high-purity anionic surfactant widely recognized for its excellent detergency, foaming, and emulsifying properties. This compound is a critical raw material for formulators requiring consistent performance and reliable supply chain integrity. It is essential for manufacturers in the detergent, personal care, textile, and industrial cleaning sectors seeking to enhance the efficacy and stability of their products.

Application

• Detergent & Cleaning Formulations: Primary surfactant in liquid and powder laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Personal Care Products: Key foaming and cleansing agent in shampoos, body washes, and hand soaps.
• Textile Processing: Used as a wetting agent, dispersant, and scouring agent in textile manufacturing and dyeing processes.
• Industrial & Institutional (I&I) Cleaners: Component in heavy-duty degreasers, floor cleaners, and metal cleaning formulations.
• Emulsion Polymerization: Serves as an emulsifier and stabilizer in the production of synthetic rubbers, plastics, and latex paints.
• Agricultural Formulations: Used as a wetting and dispersing agent in pesticides and herbicides.
• Oilfield Chemicals: Employed in drilling mud formulations and as a component in enhanced oil recovery processes.

Quality Control

Our Sodium Dodecylbenzenesulphonate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high performance. Each lot is tested against rigorous internal specifications for critical parameters such as active matter content, free oil, and inorganic salt. A Certificate of Analysis (COA) documenting purity, physical properties, and conformance is available for every shipment upon request.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
