Description

Sodium 12-Hydroxyoctadecanoate is the sodium salt of 12-hydroxyoctadecanoic acid, a key derivative of ricinoleic acid. This compound serves as a versatile anionic surfactant and emulsifying agent, valued for its ability to modify surface tension and stabilize formulations. It is essential for manufacturers in the cosmetics, personal care, and industrial lubricant sectors seeking reliable, high-performance ingredients.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and surfactant in creams, lotions, and hair conditioners.
• Industrial Lubricants & Greases: Functions as a thickening agent and stabilizer in lithium-based and other complex grease formulations.
• Textile Processing: Used as a softening agent, lubricant, and anti-static agent in fiber treatment and finishing.
• Metalworking Fluids: Serves as a corrosion inhibitor and emulsifier in soluble oils and coolants.
• Soaps & Detergents: Employed as a specialty soap base and co-emulsifier for enhanced cleaning and foaming properties.
• Pharmaceutical Excipients: Utilized as an emulsifying agent in topical ointments and creams.
• Agricultural Adjuvants: Enhances the spreading and sticking properties of pesticides and herbicides.
• Polymer & Plastic Additives: Acts as an internal or external lubricant and release agent during processing.

Quality Control

Our Sodium 12-Hydroxyoctadecanoate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and acid value 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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption and caking.
