Description

Sodium 1-Hydroxy-3,7-Dimethyloctanesulphonate is a high-purity, synthetic anionic surfactant derived from a branched-chain fatty alcohol. This compound is valued for its excellent wetting, emulsifying, and foaming properties, making it a versatile functional ingredient in demanding formulations. It is primarily utilized by manufacturers in the personal care, industrial cleaning, and textile processing industries seeking reliable performance and consistent quality.

Application

• Personal Care & Cosmetics: Acts as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, hard surface cleaners, and floor care products for superior wetting and soil penetration.
• Textile & Leather Processing: Functions as a wetting agent, leveling agent, and emulsifier in dyeing, scouring, and finishing operations.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide sprays to enhance spreading and adhesion on plant surfaces.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic latexes and polymers.
• Metal Working Fluids: Incorporated as a surfactant component to improve the emulsification and stability of coolants and lubricants.

Quality Control

Our Sodium 1-Hydroxy-3,7-Dimethyloctanesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profiles are available upon request 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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation of performance.
