Dihomo-gamma-Linolenic Acid

Dihomo-gamma-Linolenic Acid (CAS 1783-84-2), also known commercially as Eicosatrienoic acid, is a 20-carbon polyunsaturated omega-6 fatty acid occurring naturally in human tissue and select botanical oils. It functions as a bioactive lipid precursor and skin-conditioning agent across pharmaceutical, nutritional, and cosmetic applications. In cosmetic formulations, it is incorporated into moisturizers and barrier repair products.

Its skin-conditioning properties support lipid replenishment in the stratum corneum. Nutritional supplement manufacturers use it as a functional fatty acid ingredient in softgel and oil-based formats targeting omega-6 fatty acid profiling. Pharmaceutical researchers source it as a reference standard or active ingredient in investigational lipid-based formulations. In specialty food and nutraceutical products, it contributes to targeted fatty acid enrichment.

This occurs where precise omega-6 composition is a formulation requirement. Dihomo-gamma-Linolenic Acid is supplied as a neat liquid oil or in solution, depending on concentration and intended use. It is available in research-grade and cosmetic-grade specifications, with purity levels typically confirmed by GC analysis. Packaging ranges from small quantities for laboratory and formulation development.

Larger volumes are available for commercial production runs. This ensures that manufacturers can scale their operations from initial research phases through to full market distribution and supply chain management.
