Overview
Nervonic acid (CAS 506-37-6 ), also known as cis-Selacholeic acid, is a long-chain monounsaturated fatty acid occurring naturally in shark liver oil, mustard seed oil, and mammalian brain tissue.
It is sourced commercially for applications requiring high-purity fatty acid fractions with specific chain-length and unsaturation profiles. Demand is driven primarily by nutritional, cosmetic, and specialty industrial sectors.
In food and nutraceutical formulations, it is incorporated into infant formula lipid blends and brain-health supplements targeting myelin synthesis support. Personal care formulators use it in premium skin and hair care products.
Its long-chain fatty acid profile contributes to emollient performance and film formation on the skin surface. In lubricant formulations, it functions as a boundary lubricant additive or surface modifier in metalworking fluids.
Fatty acid chain length influences film durability in these industrial applications. Specialty emulsifier systems also incorporate this acid as a functional component in dispersions requiring precise fatty acid composition.
The product is supplied as a white to off-white powder or waxy solid. It is available in research-grade and high-purity commercial grades, with purity levels typically ranging from 90% to 98%+.
Packaging ranges from small quantities for R&D procurement to bulk quantities for industrial and nutritional manufacturing. Our supply chain ensures consistent quality for technical and nutritional applications.
