Description

Potassium Isooctadecanoate is a potassium salt of a branched-chain fatty acid, serving as a versatile anionic surfactant and chemical intermediate. This compound is valued for its emulsifying, dispersing, and stabilizing properties in complex formulations. It is primarily utilized by manufacturers in the personal care, industrial lubricant, and polymer processing sectors seeking high-performance additives.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier and cleansing agent in soaps, creams, lotions, and shaving products.
• Industrial Lubricants & Greases: Functions as a thickening agent and soap structure builder in lithium and calcium complex greases.
• Polymer Industry: Used as an internal or external lubricant and release agent in PVC and other plastic processing.
• Textile Processing: Serves as a softener, lubricant, and antistatic agent for synthetic and natural fibers.
• Metalworking Fluids: Employed as a corrosion inhibitor and emulsifier in soluble oils and drawing compounds.
• Agricultural Formulations: Aids in the emulsification and dispersion of pesticides and herbicides.
• Paints & Coatings: Acts as a wetting and dispersing agent for pigments in water-based systems.
• Cleaning Products: Provides detergency and foam control in industrial and institutional cleaners.

Quality Control

Our Potassium Isooctadecanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and acid value is provided with every shipment 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
