Description

Linoleic acid is an essential polyunsaturated ω-6 fatty acid, a fundamental building block in biochemistry and industrial synthesis. Its high degree of unsaturation makes it a versatile and reactive intermediate for producing a wide range of derivatives. This compound is critical for manufacturers in the pharmaceutical, nutraceutical, cosmetic, and chemical synthesis sectors, where it serves as a key raw material for emulsifiers, soaps, and bioactive compounds.

Application

• Pharmaceutical & Nutraceutical Intermediates: Used in the synthesis of conjugated linoleic acid (CLA) and other bioactive lipid compounds for dietary supplements and health products.
• Cosmetic & Personal Care Formulations: Acts as an emollient and skin-replenishing agent in creams, lotions, and serums, valued for its role in maintaining the skin's lipid barrier.
• Soap & Detergent Manufacturing: A key fatty acid component in the production of high-quality soaps, offering good lathering and cleansing properties.
• Polymer & Resin Production: Serves as a monomer or modifier in the creation of alkyd resins, polyesters, and other polymers, imparting flexibility.
• Food Industry Applications: Employed as a nutritional additive and in the fortification of food products, though typically in highly purified grades.
• Research & Biochemical Reagents: Used as a standard and reagent in lipid metabolism studies, cell culture media supplementation, and analytical chemistry.
• Lubricant & Grease Additives: Functions as a precursor for specialty esters used in biodegradable lubricants and metalworking fluids.
• Surfactant & Emulsifier Synthesis: A critical raw material for producing non-ionic and anionic surfactants used in agrochemicals and industrial cleaners.

Quality Control

Our Linoleic Acid is produced and tested under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets precise specifications for purity, identity, and stability. Certificates of Analysis (COA) documenting key parameters such as assay, fatty acid profile, and peroxide value are provided to guarantee traceability and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to minimize peroxide formation. Keep away from heat, sparks, and open flames.
