Description

Sodium 1-Methyl 10-(Sulphooxy)Octadecanoate is a specialized anionic surfactant and sulfated fatty acid ester derivative. This compound is valued for its unique combination of hydrophobic alkyl chain and hydrophilic sulfated ester group, offering excellent emulsifying, wetting, and dispersing properties. It is primarily utilized in the formulation of high-performance industrial lubricants, metalworking fluids, textile auxiliaries, and specialty cleaning agents where stable emulsions and surface activity are critical.

Application

• As a key emulsifier and stabilizer in the production of synthetic and semi-synthetic metalworking fluids and coolants.
• An essential component in textile processing for scouring, dyeing, and finishing operations to improve wetting and fiber penetration.
• Used in the formulation of industrial and institutional (I&I) cleaning products and degreasers for hard surface cleaning.
• As a co-emulsifier and lubricity agent in the manufacture of specialty lubricants and greases.
• In the leather industry as a fat-liquoring agent to soften and lubricate leather fibers.
• Potential use as an intermediate for the synthesis of more complex surfactants and specialty chemicals.

Quality Control

Our production of Sodium 1-Methyl 10-(Sulphooxy)Octadecanoate adheres to stringent quality management protocols. Each batch is analyzed to ensure consistent chemical composition, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and sulfate content are provided and available upon request to support your quality assurance processes.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance and flow characteristics.
