Top China Blue Copper Peptide GHK-Cu Powder Factory & Supplier serving the France Market

Our Blue Copper Peptide powder is produced in accordance with ISO 22000 and Good Manufacturing Practices. Each lot is supplied with a full regulatory file including the CAS number (89030-95-5 / 49557-75-7 for free peptide), INCI designation ([N-(N-Glycyl-L-histidyl)-L-lysinato]copper), detailed quantitative residual solvent reports (GC-MS), absence of prohibited CMR substances, and heavy metal limits compliant with ANSM guidelines (Lead ≤ 2 ppm, Arsenic ≤ 1 ppm, Mercury ≤ 0.1 ppm). This allows direct inclusion into your Product Information File (PIF) and smooth cosmetic portal notification on the CPNP.

GHK-Cu is an ionically coordinated peptide complex that requires specific formulation conditions. It is highly water-soluble but prone to cleavage when exposed to intense heat or strong chelators. Formulators should dissolve the lyophilized powder in demineralized water below 40°C during the cool-down phase of emulsion creation. The final formulation pH must be maintained between 5.5 and 7.0. Strong copper-chelating agents like Disodium EDTA or Tetrasodium EDTA must be avoided, as they will compete with the peptide backbone and strip the Cu2+ ion, destroying the characteristic blue hue and biological efficacy.

We strongly advise against directly blending GHK-Cu with low-pH formulations containing L-ascorbic acid, glycolic acid, or salicylic acid (pH < 4.5). The high acidity dissociates the copper-peptide coordinate bond, causing peptide degradation and neutralizing antioxidant properties. For clinical skin-brightening or resurfacing lines, our technical application specialists suggest separating GHK-Cu into morning repair routines or microencapsulating the active ingredient to avoid direct interactions.

We support standard international shipping terms including FOB, CIF, CFR, and fully cleared DDP (Delivered Duty Paid) directly to your facilities in France. High-value peptide consignments are packaged in light-protected, nitrogen-flushed, vacuum-sealed aluminum containers accompanied by international flight-safe non-hazardous transport documentation (IATA DGR declaration). Transit time via express air freight (DHL/FedEx priority) from Xi'an to Paris-Charles de Gaulle (CDG) or Lyon-Saint Exupéry (LYS) takes 3 to 5 business days.

Yes. We routinely provide qualified French cosmetic manufacturers and R&D centers with free 1g–5g laboratory samples alongside the batch-specific Certificate of Analysis. This enables your internal analytical department or contracted testing facilities (such as Eurofins or SGS France) to independently evaluate colorimetric intensity, moisture loss on drying, optical rotation, and HPLC chromatographic profile before placing commercial production orders.
