FAQ
What is OPC in grape seed extract?
OPC refers to oligomeric proanthocyanidins, the core polyphenolic fractions naturally present in Vitis vinifera grape seeds. It is the primary standardized marker for high-grade grape seed extract used in cosmetic and nutritional formulation industries.
What is the difference between OPC and total polyphenols?
Total polyphenols represent the overall phenolic content of grape seed extract, while OPC specifically refers to oligomeric proanthocyanidin fractions. High-OPC grades focus on concentrated active oligomeric components, delivering more standardized formulation performance.
Is grape seed extract powder water soluble?
Standard grape seed extract powder features good water dispersibility and compatibility in aqueous solutions, beverages, and powder blend systems, adapting to most cosmetic and nutritional formula types.
What extraction solvent is used for this 95% OPC grape seed extract?
This premium grade adopts food-grade ethanol extraction, which effectively purifies proanthocyanidin fractions while maintaining ingredient safety and purity for global food and cosmetic compliance.
How should grape seed extract powder be stored?
To preserve compositional stability, store the powder in sealed packaging under cool, dry and dark conditions, avoiding high humidity and direct light exposure.
What is the typical specification for industrial-grade grape seed OPC?
Common industrial specs include 80% total polyphenols and 95% proanthocyanidins. The 95% OPC grade is widely used for high-standard cosmetic and premium nutritional formulations.
Is grape seed extract suitable for cosmetic formulations?
Yes. Standardized grape seed polyphenol and proanthocyanidin ingredients are widely integrated into skincare and personal care formulas for stable formulation compatibility and botanical ingredient enrichment.
