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?
RawSource supplies the standardized powder extract in bulk to formulators and supplement manufacturers. Pricing is volume-dependent; request a bulk quote with your target specification, and CoA and SDS documentation is available on request.
