1. What is Standardised Grape Seed Extract Powder?
Standardised Grape Seed Extract Powder is a natural polyphenolic functional ingredient derived from the seeds of mature fruits of the grapevine species Vitis vinifera L., produced through modern plant extraction and separation purification techniques. Within the grape processing industry chain, grape seeds constitute one of the primary by-products of winemaking and juice processing.
Within the cosmetics sector, Standardised Grape Seed Extract Powder is explicitly positioned as a natural antioxidant and anti-ageing botanical ingredient, primarily employed to enhance formulation systems' defence against environmental oxidative stress. Compared to synthetic antioxidants, Standardised Grape Seed Extract Powder offers natural origins, robust safety foundations, and synergistic multi-component benefits, aligning with the industry's current trends towards naturalisation, efficacy-driven formulations, and scientifically substantiated claims.
Core Active Ingredients
The primary active component in Standardised Grape Seed Extract Powder is Oligomeric Proanthocyanidins (OPCs). Additionally, it contains catechins, epicatechins, proanthocyanidins, and minor gallic acid derivatives.
According to a 2023 study in the journal Food Science analysing grape seed polyphenolic constituents, OPCs typically constitute over 60% of the total polyphenols in Standardised Grape Seed Extract Powder, forming the primary material basis for its antioxidant efficacy (Source: Food Science, Vol. 44, 2023).

4. Is Grape Seed Extract Effective?
- Antioxidant and Free Radical Scavenging Effects
The OPCs in Standardised Grape Seed Extract Powder neutralise free radicals through hydrogen or electron transfer mechanisms, thereby interrupting the lipid peroxidation chain reaction. According to an in vitro study published in the Journal of Food and Biotechnology in 2023, grape seed extract demonstrated over 90% scavenging efficacy in the DPPH radical model (Source: Journal of Food and Biotechnology, Vol. 42, 2023).
- Anti-ageing and Collagen Protection Mechanism
Collagen degradation is a key factor in skin ageing. Research indicates that Standardised Grape Seed Extract Powder inhibits the activity of matrix metalloproteinases such as MMP-1 and MMP-9, thereby delaying collagen degradation (Source: International Journal of Dermatology, 2022).
- Anti-inflammatory and Soothing Effects
OPCs modulate the NF-κB signalling pathway, reducing expression of inflammatory cytokines IL-6 and TNF-α, thereby alleviating skin inflammation triggered by environmental stimuli (Source: Chinese Journal of Experimental Formulary, 2023).
- Photoprotective Mechanisms
Research published in the Journal of Photochemistry and Photobiology (2023) indicates that Standardised Grape Seed Extract Powder mitigates UV-induced oxidative skin damage, making it commonly incorporated into sunscreen and post-sun care formulations (Source: JPP 2023).
5. What Are the Applications of Grape Seed Extract?
Standardised Grape Seed Extract Powder is primarily utilised in the following cosmetic applications:
- Anti-ageing serums and ampoules
- Repairing emulsions and creams
- Sun protection and post-sun care products,
- Eye care formulations
- Antioxidant soothing masks
The product is primarily available in the form of standardised plant extract powder, allowing for customisation of OPC content, making it easy for OEM/ODM customers to design their own formulas.
