Description

9-(Sulphooxy)Octadecanoic Acid is a specialized fatty acid derivative, also known as sulfated stearic acid, which combines the hydrophobic properties of a long carbon chain with a hydrophilic sulfated group. This unique amphiphilic structure makes it a valuable intermediate for creating surfactants and emulsifiers with specific performance characteristics. It is primarily sought by manufacturers in the chemical synthesis, personal care, and textile processing industries for its role in modifying surface activity and compatibility.

Application

• Surfactant Intermediate: A key raw material for synthesizing anionic surfactants used in industrial and institutional cleaning formulations.
• Textile Auxiliary: Employed in fiber processing, dyeing, and finishing operations as a wetting, leveling, or softening agent.
• Personal Care Ingredients: Serves as a base for creating mild surfactants and emulsifiers in shampoos, body washes, and skincare products.
• Lubricant Additive: Used in the formulation of metalworking fluids and industrial lubricants for its emulsifying and anti-corrosion properties.
• Leather Processing: Acts as a fatliquoring agent to soften and waterproof leather during tanning.
• Paper Sizing Agent: Enhances the water resistance and printability of paper and paperboard.
• Emulsion Polymerization: Functions as an emulsifier in the production of synthetic latexes and polymers.
• Research & Development: Utilized in chemical research for studying sulfate ester chemistry and developing new specialty chemicals.

Quality Control

Our 9-(Sulphooxy)Octadecanoic Acid is produced under a stringent quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, including identity, purity, and sulfate content. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
