Description

Sodium 3,6,9,12,15,18,21,24,27,30,33,36-Dodecaoxaoctatetracontyl Sulphate is a high-purity, non-ionic surfactant derivative with a long polyether chain, offering exceptional solubility and surface activity in aqueous systems. This compound is valued for its ability to reduce surface tension, enhance wetting, and stabilize formulations without contributing significant ionic character. It is essential for manufacturers in the personal care, industrial cleaning, and specialty chemical sectors who require a reliable, high-performance surfactant for demanding applications.

Application

• Personal Care Formulations: Acts as a primary or co-surfactant in shampoos, body washes, and facial cleansers for gentle yet effective cleansing and rich foam stabilization.
• Industrial & Institutional (I&I) Cleaners: Used in hard surface cleaners, degreasers, and detergent blends for its superior wetting and emulsifying properties on oils and greases.
• Textile Processing: Functions as a wetting agent, dye leveling agent, and scouring aid to improve processing efficiency and fabric quality.
• Agrochemical Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces, improving efficacy and rainfastness.
• Paint & Coating Additives: Serves as a dispersing and wetting agent in water-based paints to improve pigment dispersion and application properties.
• Metal Working Fluids: Incorporated into coolants and lubricants for its emulsification and corrosion inhibition properties.

Quality Control

Our Sodium 3,6,9,12,15,18,21,24,27,30,33,36-Dodecaoxaoctatetracontyl Sulphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Key parameters such as active matter content, sulfate content, and ethylene oxide distribution are verified. Certificates of Analysis (COA) documenting full specifications 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
