Details
What it is
The same copper-glycyl-histidyl-lysine complex, supplied by the gram as a cosmetic raw material under the INCI name copper tripeptide-1. The gram format exists because a formulator works by weight into a batch rather than by the vial.
Also sold as: copper tripeptide-1, INCI copper tripeptide-1
- As suppliedPowder, sold by the gram. Deep blue.
- Into solutionWater-soluble. Added to the water phase.
Class: Copper tripeptides.
Reconstitution and handling
Handling
- As suppliedLyophilised powder
- Sealed, refrigeratedMonths
- In solutionRefrigerate, use short-term
Concentration is mass divided by the volume you added. A 1g sachet made up to one millilitre of solvent gives 1g per millilitre; to two millilitres, half that. Record the volume you used: a solution whose concentration is not written down is a solution you cannot use quantitatively.
The full procedure is on our reconstitution guide, with a concentration calculator; what is known about keeping these materials is on storage and stability. Bacteriostatic water and acetic acid are both in our catalogue and can be ordered with a product or on their own.
Bulk pricing
Your tier is set by the total kits in your basket across every compound, not per line. The full ladder is published on our bulk pricing page: nothing is gated, there is no code to enter and nothing to apply for.
