Description

Palmitoleic acid (CAS 373-49-9 ), also known as zoomeric acid, is a monounsaturated omega-7 fatty acid sourced primarily from sea buckthorn, macadamia oil, and marine lipids. It functions as a bioactive lipid ingredient in nutritional, cosmetic, and pharmaceutical formulations where fatty acid profile and skin-compatibility are key sourcing criteria for manufacturers. In personal care, it is incorporated into facial creams, serums, and barrier-repair products where its structural similarity to skin sebum supports emollient performance and formulation stability. Nutraceutical manufacturers use it as an active ingredient in omega-7 supplements targeting metabolic and cardiovascular health positioning. Food formulators source it to enrich functional lipid blends. Pharmaceutical researchers also use it as a reference standard or active component in lipid-based drug delivery systems. It is available as a liquid oil or in concentrated free fatty acid form. Purity grades typically range from technical to high-purity for specialty applications. Food-grade and cosmetic-grade specifications are the most commonly traded forms in the chemical market. It is also available as a standardized extract within sea buckthorn oil fractions, depending on the intended application. Quality is maintained according to industry standards for lipid purity.
