Description

Sodium Dodecyl Sulfate (SDS) is a highly versatile anionic surfactant with excellent foaming, emulsifying, and wetting properties. Its primary value lies in its ability to reduce surface tension, making it indispensable for creating stable formulations and facilitating cleaning and dispersion processes. This compound is a critical raw material for manufacturers in the personal care, pharmaceutical, and industrial cleaning sectors who require a reliable and effective surfactant.

Application

• Detergent & Cleaning Formulations: A key foaming and degreasing agent in industrial cleaners, car wash soaps, and household detergents.
• Personal Care Products: Widely used as a primary surfactant in shampoos, body washes, toothpastes, and bubble baths for its rich lather.
• Pharmaceutical & Life Sciences: Essential component in electrophoresis buffers (SDS-PAGE) for protein denaturation and separation.
• Textile & Leather Processing: Acts as a wetting agent, emulsifier, and leveling agent in dyeing and finishing processes.
• Emulsion Polymerization: Serves as an emulsifier in the production of synthetic rubber, latex, and various polymer dispersions.
• Agricultural Formulations: Used as a wetting and dispersing agent in pesticides, herbicides, and foliar sprays.

Quality Control

Our Sodium Dodecyl Sulfate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer grades suitable for various applications, including technical and high-purity standards. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and loss on drying are provided with every shipment 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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent caking and degradation due to moisture absorption.
