Copper Peptide Powder is a chemical substance with the molecular formula C14H24N6O4.
It is a complex of glycyl histidine tripeptide (GHK) and copper, and its aqueous solution is blue, so it is also known as "blue copper" peptide.
CHK-Cu has high application value in topical skincare products, as it can resist oxidation, anti-aging, wrinkle removal, promote wound healing, repair damaged skin, and improve skin density and toughness.
★What is the minimum order quantity (MOQ) for Copper Peptide Powder？
The standard MOQ for Copper Peptide is 10g. However, small orders are usually acceptable on the condition that the full sample charge is paid.
★How to confirm the quality of Copper Peptide before placing a formal order?
To ensure quality compliance, you can take the following steps:
- Request samples (you only need to bear the shipping cost or arrange a courier to pick up samples) and conduct third-party testing or self-inspection;
- Ask for a batch-specific Certificate of Analysis (COA), which should include HPLC purity test results, mass spectrometry confirmation, copper content detection, and microbial test reports;
★What is the delivery lead time for Copper Peptide Powder?
Delivery Lead Time: Generally 7-9 working days after payment confirmation (excluding Chinese holidays). For large orders (≥20kg), the lead time may be extended to 15 days, and customized orders require negotiation with us.
★What is the safe addition ratio of Copper Peptide Powder in cosmetic end products?
The safe addition ratio of Copper Peptide in cosmetic end products varies by product type, following relevant regulatory requirements and industry practices:
- Leave-on products (serums, creams, masks): 0.01%–0.1% (the maximum historical usage in Chinese leave-on products is 8%, but 0.01%–0.1% is the most cost-effective and safe range for daily anti-aging, repair, and skin barrier protection);
- Rinse-off products (cleansers, shower gels): 0.005%–0.05% (lower ratio is sufficient due to short skin contact time);
★Is Copper Peptide Powder allowed to be added to cosmetics in China, the EU, the US, South Korea, and Japan?
Copper Peptide (INCI Name: COPPER TRIPEPTIDE-1, also known as GHK-Cu) is allowed to be added to cosmetics in all five regions.
★Which cosmetic ingredients work better when paired with Copper Peptide Powder?
Hyaluronic Acid,as a natural moisturizing factor, hyaluronic acid can deeply hydrate the skin, improve skin plumpness, and create a moist environment for Copper Peptide to play its role.
Niacinamide
Niacinamide improves skin texture, fades dullness, regulates sebum secretion, and strengthens the skin barrier. When paired with Copper Peptide, it can synergistically enhance skin repair and anti-aging effects—Copper Peptide promotes collagen and elastin synthesis, while niacinamide brightens the skin and reduces fine lines, making it suitable for anti-aging serums, creams, and spot-lightening products.
Ceramide
Copper Peptide repairs damaged barrier cells, while ceramides fill the gaps between skin cells, accelerating barrier recovery. This combination is especially suitable for products targeting sensitive, red, or barrier-damaged skin (e.g., repair serums, barrier creams).
Collagen& Elastin Peptides
These peptides can supplement the skin’s lost collagen and elastin, while Copper Peptide promotes the body’s own collagen synthesis. The combination of exogenous supplementation and endogenous promotion significantly enhances the anti-aging and skin-firming effects, suitable for anti-wrinkle serums, firming creams, and anti-aging masks.
★What is the solubility of Copper Peptide Powder (GHK-Cu) for cosmetic formulation?
- Solubility in Water: Copper Peptide is highly soluble in water, and its aqueous solution presents a clear blue color.
- Solubility in Other Polar Solvents: It is slightly soluble in dimethyl sulfoxide (DMSO), another common polar solvent, but DMSO is rarely used in large quantities in cosmetic formulations due to its strong irritation, so it is not recommended as the main solvent for dissolving Copper Peptide. It is slightly soluble in weakly acidic solutions, and adjusting the solution pH to 4.5–7.4 (the stable pH range of Copper Peptide) can help improve its solubility and stability simultaneously.
- Solubility in Non-Polar Solvents: Copper Peptide is almost insoluble in non-polar solvents such as mineral oil, vegetable oil, and ethanol, which means it cannot be directly added to oil-based cosmetic formulas. If it needs to be added to oil-based products (such as facial oils, oil-based creams), a suitable emulsifier must be used to disperse it evenly in the oil phase to avoid precipitation and ensure the stability of the finished product.
