Grape seed extract

Grape Seed Extract (CAS 84929-27-1, EC 284-511-6) is a concentrated botanical extract derived from Vitis vinifera seeds, standardised for proanthocyanidin content. It is also referenced under the synonym Unii-T3pw93ib4q and commonly identified by its proanthocyanidin or OPC fraction. No E-code designation applies to this ingredient.

In food and nutraceutical formulations, proanthocyanidins scavenge free radicals and chelate metal ions, slowing lipid oxidation in functional foods and dietary supplements. In personal care, the extract inhibits oxidative degradation of emulsion systems and supports skin-conditioning claims in anti-ageing topicals. Pharmaceutical applications leverage its antioxidant activity in standardised capsule and tablet formats.

Grape Seed Extract is supplied as a dry powder in standardised grades, typically 95% proanthocyanidins by UV assay. Compliance documentation available includes REACH registration support, FCC-aligned specifications, and certificates of analysis. Packaging is offered in fibre drums and multi-layer bags suited to bulk procurement.
