Diospyros kaki fruit extract

Diospyros Kaki (Persimmon) Fruit Extract is highly valued for its high concentration of tannins, flavonoids, and Vitamin C. In skincare, it functions as a potent antioxidant and skin-conditioning agent, specifically known for its pore-tightening (astringent) properties and ability to inhibit melanin production for brightening effects. In dietary supplements, it is utilized for its anti-inflammatory and digestive health benefits. Buyers should request a High-Performance Liquid Chromatography (HPLC) report to verify the percentage of active polyphenols.

Buyers must specify the extraction ratio (e.g., 10:1 or 20:1) or the standardized content of active ingredients. For cosmetic formulations, water solubility is critical; ensure the powder is 100% cold-water soluble with no visible sediment to prevent issues in liquid serums or toners. Additionally, check the mesh size (typically 80-100 mesh) to ensure fine texture and ease of integration into various product bases.

For global trade, the extract must have a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. If intended for the US market, ensure the supplier follows FDA GRAS (Generally Recognized as Safe) guidelines or INCI (International Nomenclature Cosmetic Ingredient) naming for cosmetics. For European markets, REACH compliance and Cosmos/Ecocert certifications are highly preferred to prove the organic and sustainable origin of the raw persimmons.

Diospyros Kaki extract is sensitive to light, heat, and moisture. Professional suppliers should provide stability testing data. Ensure the product is packed in double-layer food-grade plastic bags inside fiber drums or vacuum-sealed aluminum foil bags. The standard shelf life should be 24 months when stored in a cool, dry place away from direct sunlight. Requesting a heavy metal and microbiological test report (covering Lead, Arsenic, Mercury, and E. coli) is essential to ensure the product doesn't degrade or become contaminated during transit.

Adulteration is a common risk in the herbal extract industry. To mitigate this, never rely solely on the supplier's internal COA. Use a third-party inspection service (like SGS or Intertek) to perform random sampling before the balance payment. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site factory verifications to ensure their production capacity and quality control systems are legitimate.

Prices for botanical extracts fluctuate based on the harvest season of the raw fruit. To get the best rate, consider annual contract purchasing rather than spot buying. For new buyers, negotiate a tiered pricing structure: start with a small paid sample (100g-500g), followed by a trial order at a slightly higher price, with a written agreement that the price will drop by 10-15% once cumulative volume reaches 500kg.

Plant extracts are often flagged by customs for phytosanitary inspection. Ensure the supplier provides a Phytosanitary Certificate if required by your country's agricultural department. For shipping, Air Freight is recommended for high-value extracts to minimize exposure to humidity, while Sea Freight (LCL) is more economical for bulk orders over 200kg. Always use Incoterms 2020 (like CIF or DAP) to clearly define where the risk transfers from seller to buyer.

To protect your capital, utilize secure payment escrow services provided by reputable B2B platforms like Made-in-China.com. Avoid direct wire transfers to private bank accounts. Ensure the Proforma Invoice (PI) explicitly states the specification of the extract (e.g., Polyphenol content ≥30%), as this document serves as your primary evidence in the event of a quality dispute or refund claim.
