GHK-Cu — Cosmetic Grade

Blue Copper Peptide (GHK-Cu) Powder —

A cosmetic-grade copper peptide supplied as a blue-violet crystalline powder, standardized to ≥ 99.0% assay by HPLC. The tripeptide glycyl-L-histidyl-L-lysine is chelated with copper(II), and that complex is what gives the material its characteristic colour. The powder dissolves completely in water for direct incorporation into aqueous, emulsion and gel systems. Packed with a per-batch COA, from 1 g upward.

Product Highlights

99% Purity: Cosmetic grade copper tripeptide-1, batch tested with COA for consistent quality.

1g Vials: Pre-weighed single-gram vials for clean sampling and precise formulation trials.

Copper Carrier: The GHK peptide binds copper and carries it into skin cells to support collagen and elastin formation.

Water Soluble: Blends directly into serum, cream and eye care formulas without extra processing steps.

Sample First: One 1g vial is enough to evaluate — MOQ starts at just 1 gram.

Factory Direct: Strict QC with COA per batch, competitive pricing and stable bulk supply for wholesalers.

Formulation Features

Cold-Process Water Phase

Dissolves at ambient temperature, so it can be dosed late in the batch and integrated without adding a heating or cooling step to the line.

pH 5.0–7.0 Working Range

The practical window for the copper-peptide complex, and the range most modern aqueous, emulsion and gel systems already sit inside.

Inherent Colour, Clean Label

Blue-violet comes with the molecule. Formulators can carry the tone into the finished product or mask it — either way, no separate colorant goes on the label.

Low Dose, High Value

Working levels of 0.01%–0.1% mean a small pack goes a long way, which keeps trial costs down while you set the final concentration.

Applications

Facial Serums & Essences

A water-phase ingredient for lightweight serum formats, including the anti-aging-positioned lines where copper peptides are already an established concept.

Creams, Lotions & Eye Care

Added to the water phase before emulsification in facial creams, body lotions and eye-area products.

Sheet Masks, Gels & Ampoules

Clear aqueous formats that need full solubility and a clean solution, without sediment or cloudiness developing in the pack.

Scalp & Hair Care Concepts

Selected by formulators working on scalp serums and hair-care products, supplied in bulk for contract manufacturing.

Private-Label Skincare Lines

Supplied from gram-level trial packs up to 25 kg drums, with OEM packing and private-label support for brands building their own range.
