Description

Fatty Acids, C18-Unsaturated, Trimers, Potassium Salts is a potassium soap derived from the oligomerization of unsaturated C18 fatty acids, primarily oleic acid. This compound matters as a versatile, water-soluble surfactant and emulsifier, offering excellent stability and compatibility in aqueous systems. It is needed by manufacturers in the personal care, industrial lubricant, textile processing, and agrochemical formulation industries seeking effective anionic surface-active agents.

Application

• Primary Emulsifier & Stabilizer in cosmetic and personal care products such as creams, lotions, and hair conditioners.
• Textile Processing Aid for scouring, dyeing, and finishing operations, improving wetting and fiber lubrication.
• Industrial Lubricant Additive and metalworking fluid component, providing corrosion inhibition and emulsification.
• Agrochemical Adjuvant in pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Soap and Detergent Intermediate for producing specialized liquid soaps and high-performance cleaning compounds.
• Latex and Polymerization Aid acting as an emulsifier in the production of synthetic rubbers and polymers.

Quality Control

Our Fatty Acids, C18-Unsaturated, Trimers, Potassium Salts is produced under a rigorous quality management system. Each batch is tested to ensure consistent composition, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) detailing assay, acid value, saponification value, moisture content, and other critical parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
