Description

Sodium 1-Methyl 10-Sulphooctadecanoate is a high-purity anionic surfactant derived from a branched-chain fatty acid. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. It is a critical ingredient for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking superior performance and stability.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in shampoos, body washes, and facial cleansers, providing rich lather and mildness.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, hard surface cleaners, and floor care products for its powerful wetting and soil suspension capabilities.
• Textile Auxiliaries: Serves as a key component in scouring agents, dye leveling agents, and fabric softeners for the textile industry.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of synthetic rubbers, latex paints, and acrylic polymers.
• Agricultural Formulations: Employed as a wetting and spreading agent in pesticide and herbicide concentrates to enhance coverage and efficacy.
• Leather Processing: Used in fatliquoring and dyeing processes to improve the softness and uniformity of leather goods.

Quality Control

Our Sodium 1-Methyl 10-Sulphooctadecanoate 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 sulfate ash 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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
