Pinolenic acid

Pinolenic acid (CAS 16833-54-8) is a polyunsaturated fatty acid naturally occurring in pine seed oil, particularly Pinus koraiensis. It belongs to the organic acids category and is structurally a C18 trienoic acid. No assigned E-code or common trade abbreviation applies to this ingredient.

In food and nutrition, pinolenic acid is used in appetite-regulation supplements, where it stimulates the release of satiety hormones CCK and GLP-1 to reduce caloric intake. In personal care formulations, it functions as a humectant and antioxidant stabilizer, helping to protect lipid-rich emulsions from oxidative degradation while supporting skin barrier moisture retention.

Pinolenic acid is typically sourced as a concentrated fraction from Korean pine nut oil and supplied in liquid form. Suppliers operating within the EU must comply with REACH registration requirements. Buyers should confirm purity specifications and fatty acid profile certificates when evaluating grades for pharmaceutical or cosmetic applications.
