Product Overview

Copper Tripeptide-1, CAS 89030-95-5, commonly known as GHK-Cu, GHK Copper, or Copper Peptide, is a copper–peptide complex formed by the tripeptide Gly-His-Lys (GHK) and copper ions.

Its INCI name is Copper Tripeptide-1, making it a well-defined cosmetic peptide ingredient for skin-care formulation development. Compared with the uncomplexed GHK tripeptide, GHK-Cu contains coordinated copper and is typically characterized by its blue to deep-blue appearance.

Copper Tripeptide-1 is commonly positioned as a skin-conditioning cosmetic ingredient and can be incorporated into serums, creams, lotions, and other peptide-based cosmetic formulations.

Shandong Juntai Pharmaceutical supports B2B supply of GHK-Cu for cosmetic brands, formulation laboratories, ingredient distributors, and personal-care R&D projects. Product specifications, copper content, assay, packaging, and supporting documentation are confirmed according to the actual batch and project requirements.

Product Features

Defined GHK Copper Complex

GHK-Cu is formed from the tripeptide Gly-His-Lys coordinated with copper ions.

This copper-binding structure distinguishes Copper Tripeptide-1 from conventional tripeptides and gives the material its characteristic color and cosmetic ingredient identity.

Copper Tripeptide-1 Is Different from GHK

GHK-Cu and uncomplexed GHK should not be treated as the same ingredient.

This page refers specifically to Copper Tripeptide-1 / GHK-Cu, CAS 89030-95-5.

For sourcing and formulation work, CAS number, INCI name, assay, and actual product specification should be confirmed rather than substituting data from uncomplexed GHK.

Characteristic Blue Appearance

GHK-Cu commonly appears as a blue to deep-blue powder, reflecting its copper–peptide coordination structure.

For cosmetic formulation projects, appearance, solubility, dispersion behavior, and potential impact on finished-product color should be considered during formulation development.

Suitable for Peptide-Based Cosmetic Formulations

For Copper Tripeptide-1, raw-material evaluation should extend beyond a single purity value.

Relevant parameters may include:

• Product identity
• Copper content
• Assay / peptide-related quality parameters
• Appearance and color
• Solubility
• Formulation compatibility
• Storage conditions
• Batch-specific analytical documentation

These factors are particularly important for cosmetic formulators and B2B ingredient buyers.

Applications

Facial Serums

Copper Tripeptide-1 can be incorporated into peptide serums and multi-active cosmetic formulations as a skin-conditioning peptide ingredient.

Final use level and processing conditions should be determined according to the complete formulation, stability testing, and applicable cosmetic regulations.

Creams and Lotions

GHK-Cu can be used in creams, lotions, emulsions, and other leave-on skin-care systems.

Formulators should evaluate compatibility with the formulation pH, other active ingredients, chelating agents, and processing conditions before finalizing the formula.

Peptide-Based Skin-Care Formulations

Copper Tripeptide-1 can be combined with other cosmetic actives in peptide-focused skin-care products.

In multi-active systems, compatibility and stability should be verified through formulation-specific testing rather than assumed from individual ingredient specifications.

Skin-Conditioning Formulations

For cosmetic positioning, Copper Tripeptide-1 is more appropriately described using claims such as:

• Skin-conditioning ingredient
• For smoother-looking skin appearance
• For peptide-based cosmetic formulations
• For formulations targeting skin texture and overall appearance

This keeps the product within a cosmetic-use context rather than presenting it as a therapeutic or medical ingredient.

Quality & Supply

As a copper–peptide complex, GHK-Cu requires a broader quality evaluation than a conventional small-molecule cosmetic ingredient.

Frequently Asked Questions

Are GHK-Cu and Copper Tripeptide-1 the same ingredient?

In cosmetic ingredient sourcing, GHK-Cu commonly refers to Copper Tripeptide-1, a copper complex of the Gly-His-Lys tripeptide. This page refers to material associated with CAS 89030-95-5.

What is the difference between GHK-Cu and GHK?

GHK is the uncomplexed Gly-His-Lys tripeptide, while GHK-Cu is its copper-coordinated form.

They differ in molecular composition, molecular weight, color, and cosmetic ingredient identity, so their specifications should not be used interchangeably.

Why is GHK-Cu blue?

The blue color is associated with the coordination of copper ions with the GHK peptide.

Color intensity may vary depending on product form, concentration, and batch specification.

What cosmetic products can use Copper Tripeptide-1?

Copper Tripeptide-1 can be evaluated for use in serums, creams, lotions, emulsions, and other peptide-based skin-care formulations.

Final usage conditions should be determined through formulation development, stability testing, and compliance with the regulations of the target market.

What should buyers check when sourcing GHK-Cu?

Key factors include:

• INCI identity
• CAS number
• Copper content
• Assay or purity specification
• Appearance
• Solubility
• Storage requirements
• Packaging
• Batch-specific quality documentation

These parameters provide a more complete basis for raw-material qualification than relying on purity alone.

Can COA and technical documentation be provided?

The availability of COA, analytical data, and other technical documents depends on the actual supply batch.

If a project has specific documentation or testing requirements, these can be submitted during the inquiry stage for confirmation.

What is the MOQ for Copper Tripeptide-1?

MOQ depends on the requested specification, order quantity, packaging, and current supply conditions.
