Scientific Overview & Manufacturing Excellence

We specialize in the contract manufacturing and stable bulk supply of 98% Polydatin (Piceid), a highly advanced natural stilbenoid glycoside meticulously extracted and refined from premium Reynoutria japonica (commonly known as Japanese knotweed). Recognized globally by formulation scientists, Polydatin acts as a natural precursor and a more stable, highly bioavailable alternative to Resveratrol, delivering powerful antioxidant, anti-inflammatory, and cardiovascular protection.

Our factory adopts advanced extraction and multi-stage purification technology. The finished product is a uniform off-white powder characterized by exceptional biological stability. All production processes are executed in GMP-standard dust-free workshops with full ISO9001 certification and complete batch traceability, ensuring a strict and stable ≥98.0% purity index via precise HPLC detection, completely free from unrefined root impurities.

Target Application Scenarios & Formulation Benefits

Our 98% HPLC-grade Polydatin complies with stringent international cosmetic and nutraceutical raw material safety regulations. Its multi-target protective and soothing profile makes it widely utilized in:

  • ✔ Antioxidant & Anti-Aging Care: Delivers strong antioxidant properties by efficiently scavenging free radicals. It significantly reduces oxidative damage to the skin, effectively delaying cellular aging and brightening skin dullness.

  • ✔ Anti-Inflammatory & Barrier Repair: Features excellent anti-inflammatory and soothing effects. It rapidly relieves skin redness and sensitivity, actively repairs a damaged epidermal barrier, and stabilizes problematic skin conditions.

  • ✔ Cardiovascular & Microcirculation Support: Within advanced dietary supplements, Polydatin effectively regulates body microcirculation and protects cardiovascular health. It enhances overall physical antioxidant capacity to maintain systemic health.

Precautions & Formulation Guidelines

  • Storage Notice: Keep tightly sealed after opening the package. Avoid long-term exposure to high-temperature and humid environments to prevent activity degradation.

  • Formulation Superiority: Compared to Resveratrol, Polydatin possesses a glycoside bond, which gives it significantly better water solubility, higher resistance to enzymatic degradation, and improved bioavailability in both topical serums and oral capsules.

  • Compatibility Suggestion: It is highly compatible with other calming and antioxidant agents (such as Centella Asiatica, Vitamin E, and Hyaluronic Acid), synergistically enhancing overall skin barrier repair.

  • Production Operation Protection: Personnel should wear standard dust masks and gloves during weighing and feeding to prevent the inhalation of fine powder.

  • Transportation Protection: Must use light-proof and moisture-proof double-layer packaging to ensure product integrity during global transportation.

Frequently Asked Questions (Procurement & Formulation)

What is the main advantage of Polydatin over standard Resveratrol?
While both are derived from Reynoutria japonica, Polydatin is the glycoside form of resveratrol. This structural difference makes Polydatin significantly more water-soluble and far less prone to oxidation. Consequently, it offers superior formulation stability and a higher absorption rate (bioavailability) in both cosmetic serums and dietary supplements.
How does Polydatin benefit sensitive and aging skin?
Polydatin acts via robust antioxidant and anti-inflammatory pathways. It neutralizes aging free radicals to prevent dullness and wrinkles, while simultaneously suppressing localized inflammatory reactions. This dual-action approach relieves active flare-ups, redness, and promotes a calmer, stronger skin barrier.
Do you supply finished dietary supplement capsules or retail skincare serums?
No. We are strictly an upstream B2B raw material manufacturer and supplier. We provide bulk Polydatin 98% powder to empower pharmaceutical companies, dietary supplement brands, and cosmetic laboratories to manufacture their own retail products. We do not sell finished retail formulations.
Can you provide samples and complete test certificates for customs clearance?
Yes, we provide sample testing for quality and formulation verification for qualified B2B buyers. Each commercial bulk order comes with an official Certificate of Analysis (COA) specifying HPLC results, commercial invoice, packing list, and MSDS to ensure smooth global customs clearance and product filing.
