Grape Seed Polyphenol Extract Powder 1 kg

Concentrated Grape Seed Antioxidant for Skincare and Nutraceutical Manufacturing

Grape Seed Polyphenol Extract Powder in a 1 kg pack is a concentrated ingredient rich in proanthocyanidins, compounds known for their strong antioxidant capacity. This bulk format is designed for manufacturers who need a consistent supply of raw material for regular production runs, including cosmetic labs, nutraceutical formulators, and food industry facilities working with functional ingredients. The extract belongs to the Powdered Extracts and Algae category, which brings together concentrated botanical raw materials used across multiple industrial sectors.

The leading application for grape seed polyphenols is anti-aging skincare, where the compound neutralizes free radicals, supports skin firmness, and helps slow visible signs of aging in facial serums and body lotions. Beyond skin care, the extract is widely used in hair-strengthening formulas, anti-cellulite treatments, and eye contour products. Outside of cosmetics, this polyphenol concentrate is in demand in the food industry as a natural antioxidant that extends the shelf life of oils and fats, as well as in the production of dietary supplements and functional beverages thanks to its documented benefits for vascular health. Pharmaceutical manufacturers also rely on this extract when developing supplements with vessel-strengthening and antioxidant properties.

In formulations, the extract is typically added during the water or hydro-alcoholic phase at a temperature not exceeding 40-45 degrees Celsius, since excessive heat degrades a portion of the active polyphenolic compounds. Recommended dosage for cosmetic emulsions and serums ranges from 0.1 to 1 percent of the total formula weight, while dosage for food and supplement blends is adjusted individually based on the required tannin concentration. The powder dissolves readily in water and glycerin, which simplifies its incorporation into the water phase of creams, toners, gels, and serums.

Grape seed extract pairs well with other plant-based antioxidant ingredients, reinforcing the overall protective effect of a formula. A notable complementary option is Grape Berry Extract Powder 10%, which contributes additional plant pigments and nutrients from the fruit pulp. For fine-tuning concentration and testing formula strength before scaling up, the smaller Grape Seed Extract Powder 10% pack is a practical option, and the standard Grape Seed Extract Powder offers flexibility when a different sourcing profile is needed.

The powder should be stored in an airtight container, in a dry, dark place at room temperature, protected from moisture and direct sunlight, since polyphenols are sensitive to oxidation upon prolonged air exposure. The 1 kg pack suits production lines where raw material is consumed in regular batches and needs to be weighed out precisely without wasting a costly concentrate.

Begin by dispersing the xanthan gum gradually into room-temperature distilled water while stirring continuously until a smooth, lump-free gel forms. In a separate small container, dissolve the grape seed polyphenol extract and hyaluronic acid powder into the glycerin until fully blended, then incorporate this mixture into the water gel. Add the preservative last, mix thoroughly until the serum reaches a uniform consistency, and transfer the finished product into a dark glass or plastic dispenser bottle to protect the active compounds from light exposure.
