Bulk Grape Seed Extract Supplier for EU Supply
NST-8-18 is a 100:1 water-and-ethanol extract of Vitis vinifera L. seeds, standardized to OPC ≥70.0% by HPLC and proanthocyanidins ≥95.0% by UV. The reddish-brown powder contains no declared carrier or excipient and is intended for cosmetic formulations and food supplements.
Who This Product Is For
| Cosmetic formulators | For development of topical formulations requiring a standardized grape seed extract. |
|---|---|
| Food supplement manufacturers | Suitable for hard capsules, tablets, sachets and powder products. |
| Quality and R&D teams | For projects requiring defined botanical identity, extraction solvents, DER and dual assay specifications. |
Key Specifications
| Catalog number | NST-8-18 |
|---|---|
| CAS number | 84929-27-1 |
| Botanical source | Vitis vinifera L. |
| Plant part | Seed |
| Extract ratio / DER | 100:1 |
| Extraction solvents | Water and ethanol |
| Standardization | OPC ≥70.0% by HPLC; proanthocyanidins ≥95.0% by UV. These are overlapping, method-defined measurements and should not be added together. |
| Composition | 100% grape seed extract; no declared carrier or excipient |
| Appearance | Fine, reddish-brown powder |
| Solubility | Slightly soluble in water; insoluble in oil |
| Shelf life | 24 months when properly stored |
Technical & Formulation Considerations
| pH conditions | Most stable under slightly acidic to neutral conditions at pH 4.0–7.0. Strong alkalinity may promote oxidation and degradation of active polyphenols. |
|---|---|
| Processing and storage | Sensitive to light, oxygen and heat above 50 °C. Minimize unnecessary heat residence, aeration and light exposure during processing. |
| Metal compatibility | Iron and copper may contribute to discoloration or degradation; compatibility should be assessed in the intended formula and packaging system. |
| Dispersion and color | Because the extract is only slightly water-soluble, verify whether the finished system is dissolved, colloidally dispersed or suspended. Its intrinsic reddish-brown color should also be considered during shade and stability development. |
Applications
| Cosmetic formulations | Supplier-recommended use level: 0.1–1.0%. Final concentration should be confirmed through formula-specific compatibility, stability, safety and efficacy testing. |
|---|---|
| Food supplements | Suitable for hard capsules, including vegetarian HPMC or gelatin formats, as well as tablets, sachets and powders. |
| Supplement use guidance | Typical supplier-recommended use level: 100–300 mg/day, subject to applicable product-category and market requirements. |
Quality & Documentation
The current Quality Specification defines HPTLC identification, HPLC and UV assays, physical parameters, solvent and pesticide residue controls, ethylene oxide, PAHs, heavy metals and microbiological limits. Storage requirements are to keep the material cool and dry, away from strong light and heat.
The product Technical Data Sheet provides identity, DER, composition, application guidance, solubility and formulation-stability information. Recommended use levels are technical guidance and do not replace finished-product regulatory, safety or performance assessment.
