Copper Tripeptide-1

Copper Tripeptide-1 for multi-peptide formulas

Copper Tripeptide-1 is the INCI name of the copper complex of glycyl-histidyl-lysine, CAS 89030-95-5. Formulators often build it into multi-peptide serums, where it sits next to signal peptides and humectants in a leave-on base. This SKU is a water-soluble solution intended for professional cosmetic formulation, ready to add without a dissolving step.

What the documents confirm

The active INCI is Copper Tripeptide-1. The full vehicle INCI, appearance and active content are confirmed on the CoA for each lot. Take the use level from the supplier documentation for your lot.

Process and compatibility

Order of addition

Add the solution in the water phase during cool-down, below 40 °C, with gentle mixing, and avoid holding the batch hot afterward.

Stability checks

The copper complex can react with strong chelators such as EDTA, with low-pH acid systems and with ascorbic acid, which may shift color or reduce stability. Keep the serum near neutral and test color, odor and pH over time in your own packaging. The blue tint is normal and depends on concentration.

Multi-peptide serum ideas

A common architecture pairs copper peptide with a matrikine such as Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid and with an expression-line peptide such as Acetyl Hexapeptide-8 Amplified Solution, each added separately in cool-down. Glycerin and hyaluronic acid round out the base. Claims stay cosmetic: smoother-looking skin, a more even look, a comfortable finish.

Building a stable copper base

A simple, near-neutral base gives copper peptide the best chance. Start with water, a humectant such as glycerin, a polymer that tolerates the copper complex and a preservative that does not rely on strong chelators. Add the peptide last in cool-down, then record pH, color and viscosity.

Stability testing

Run stability in the final packaging at room temperature and 40 °C for several weeks. A change from blue toward green or brown, or fading color, suggests an incompatibility worth tracing back. Opaque or tinted packaging protects the look of the product.

Storage and documents

Keep the solution tightly closed, cool and away from light, and refrigerate opened material where practical. The CoA for each lot confirms active content and appearance; keep it with your batch records.

Who buys this grade

Brands that already list Copper Tripeptide-1 on an approved formula sheet often reorder the same listing to keep their documentation consistent. New projects can compare it side by side with the GHK-Cu solution and pick on CoA data, then keep that grade for the life of the product.

Two copper solutions in the catalog

GHK-Cu Copper Peptide Solution is the second solution listing with the same INCI and CAS. Formulators sometimes stock both to match an existing formula sheet or supplier history. Choose by comparing the two CoAs, and recalculate the formula if you switch between solution and powder grades. It ships from Florida, usually within 1 to 2 business days, in the pack sizes shown above, and US shipping is free on orders of $50 or more. Browse all peptide solutions.
