Frequently Asked Questions

What is grape seed extract 95%?

Grape Seed Extract 95% (CAS 84929-27-1) is a standardized extract of grape (Vitis vinifera) seed supplied at a 95% specification and rich in oligomeric proanthocyanidins (OPCs). It is used as an ingredient in cosmetic and dietary-supplement formulations.

What does the 95% specification mean?

It indicates the extract is standardized to 95% polyphenols/proanthocyanidins (OPCs), the characteristic active fraction. Standardization ensures consistent OPC content batch to batch; request the CoA for the exact assay method and basis.

What is the difference between grape seed extract and grapeseed oil?

Grape seed extract is a polyphenol-rich powder standardized for OPC content, while grapeseed oil is the pressed lipid (triglyceride) oil from the seed. They are distinct materials with different compositions and uses; this product is the 95% OPC extract.

What is grape seed extract 95% used for in formulations?

It is used as a polyphenol additive in skin-care formulations, as a standardized OPC raw material for dietary supplements, and as a proanthocyanidin source in functional blends.

How is grape seed extract 95% supplied and quoted in bulk?
