Description

Fatty Acids, C18-Unsatd., Dimers, Potassium Salts is a potassium soap derived from the dimerization of unsaturated C18 fatty acids, primarily oleic acid. This specialized surfactant offers excellent emulsifying, dispersing, and lubricating properties, making it a valuable intermediate and additive. It is particularly sought after by manufacturers in the personal care, industrial lubricants, and agrochemical sectors for formulating stable emulsions and improving product performance.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and surfactant in creams, lotions, and hair conditioners.
• Industrial Lubricants & Metalworking Fluids: Functions as a corrosion inhibitor and emulsifier in soluble oils and synthetic coolants.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates.
• Textile Processing: Serves as a lubricant and softening agent in fiber spinning and fabric finishing.
• Paints & Coatings: Employed as a grinding aid and pigment dispersant to improve color development and stability.
• Soaps & Detergents: Utilized as a specialized soap base or co-surfactant for enhanced cleaning and foaming.
• Leather Processing: Acts as a fatliquoring agent to soften and lubricate leather fibers.
• Paper & Pulp Industry: Functions as a defoamer and dispersant in paper coating and pulp processing.
