Pinolenic acid

Pinolenic acid (CAS 16833-54-8) is a rare polyunsaturated fatty acid derived primarily from pine nut oil, where it occurs as the characteristic minority component. It functions as a bioactive lipid ingredient in nutritional, cosmetic, and pharmaceutical formulations.

The compound is utilized in formulations targeting appetite regulation and skin barrier support. In food and dietary supplement manufacturing, it is incorporated into softgel capsules and functional oils marketed for satiety and weight management.

This application is based on its documented stimulation of cholecystokinin release. Cosmetic formulators use it in facial serums, emollients, and barrier creams where its skin-compatible fatty acid profile supports moisture retention.

The ingredient provides these benefits without occlusive heaviness. Nutraceutical producers blend it with other omega fatty acid concentrates to differentiate premium pine nut oil extracts for the health food market.

Pharmaceutical researchers also evaluate it as a lipid excipient or active ingredient in topical and oral delivery systems targeting inflammatory pathways. It is supplied as a liquid oil, either as a concentrated free fatty acid fraction.

It can also be provided as a glyceride-bound component within standardized pine nut oil extracts. Commercial grades are typically characterized by pinolenic acid content, commonly ranging from 15% in natural pine nut oil.

Higher-concentration purified fractions exceeding 60% are also available for specific industrial needs. Food-grade and cosmetic-grade specifications are the most commonly available for global distribution.

Documentation supports both supplement and topical applications for various manufacturing sectors. Quality control ensures the product meets rigorous standards for purity and stability in diverse formulations.
