(Z)-Palmitoleic acid

(Z)-Palmitoleic acid (CAS 373-49-9) is a monounsaturated omega-7 fatty acid, also known as Zoomeric acid or Zoomerate, and abbreviated as C16:1(n-7) or 16:1Delta9. It carries no assigned E-code. It occurs naturally in sea buckthorn oil, macadamia oil, and certain marine lipids.

In cosmetic formulations, palmitoleic acid integrates into the skin lipid barrier, supporting moisture retention through its structural compatibility with sebum. In food and nutraceutical applications, its antioxidant activity helps stabilize lipid-rich matrices against oxidative degradation. Pharmaceutical researchers also use it as an emulsification agent in lipid-based drug delivery systems.

This material is supplied as a clear liquid and is available in oleochemical-grade and high-purity research grades. It falls under REACH regulation and is classified under HS code 29161995 for customs purposes. Buyers should confirm grade-specific certificates of analysis for food or pharmaceutical end-use compliance.
