Description

γ-Linolenic Acid Ethyl Ester is the ethyl ester derivative of γ-linolenic acid (GLA), an ω-6 polyunsaturated fatty acid. This esterified form offers enhanced stability and bioavailability compared to the free acid, making it a valuable intermediate for pharmaceutical and nutraceutical development. It is primarily utilized by manufacturers in the dietary supplement, cosmeceutical, and advanced lipid research sectors seeking a high-purity, standardized source of GLA.

Application

• Pharmaceutical Intermediates: A key starting material for the synthesis of specialized prostaglandins and other bioactive lipid mediators.
• Dietary Supplements: Incorporated into softgel capsules and liquid formulations as a concentrated source of γ-Linolenic Acid (GLA).
• Cosmeceutical Actives: Used in advanced skincare products for its anti-inflammatory and skin barrier-restoring properties.
• Biochemical Research: Serves as a standard and reagent in lipidomics, metabolic studies, and inflammation research.
• Functional Food & Beverage Fortification: Employed in the enrichment of health-focused food products due to its improved oxidative stability.
• Veterinary Nutrition: Formulated into supplements for companion and livestock animals to support skin, coat, and joint health.
