Description

Linoleic Acid Sodium Salt is the sodium salt derivative of linoleic acid, a key polyunsaturated ω-6 fatty acid. This compound serves as a versatile anionic surfactant and emulsifying agent, valued for its ability to reduce surface tension and stabilize formulations. It is essential for manufacturers in the personal care, pharmaceutical, and industrial sectors seeking effective, bio-based ingredients for product development and process optimization.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and surfactant in creams, lotions, and cleansing products.
• Pharmaceutical Formulations: Used as an excipient in topical drug delivery systems and medicated ointments.
• Industrial Emulsifier: Employed in the production of polymer emulsions, lubricants, and textile processing aids.
• Research & Development: Serves as a biochemical reagent and a standard in analytical chemistry and lipid research.
• Food Industry (as an additive): Can function as an emulsifier in certain food-grade applications where specified.
• Soap & Detergent Intermediate: Used in the synthesis of specialized soaps and detergent compounds.
