Copper Tripeptide-1 Powder 5g

Copper Tripeptide-1 Powder 5g is a large-fill cosmetic-grade copper peptide raw material produced by our factory, formed as a stable chelation complex between glycyl-histidyl-lysine tripeptide (GHK) and copper ions, supplied as blue powder. Copper Tripeptide-1, i.e., GHK-Cu, is one of the most widely studied cosmetic active peptides. Copper ions in its molecule bind to the tripeptide backbone via coordination bonds, slowly releasing copper ions in the skin microenvironment, participating in activation of various enzymes including lysyl oxidase and superoxide dismutase. Our Copper Tripeptide-1 Powder 5g has 5g net content per vial, suitable for cosmetic enterprises and formulation R&D institutions with larger raw material procurement volumes, finished as blue to blue-violet crystalline powder with good water solubility and a clear blue solution.

In large-scale production of Copper Tripeptide-1 Powder 5g, we optimized drying and dispensing processes for the large-fill spec. GHK-Cu is temperature-sensitive during drying; excessive temperatures cause copper ion dissociation and product color deepening. We use low-temperature vacuum drying process with strict control of drying temperature and vacuum degree, ensuring the product maintains structural integrity and color stability during drying. 5g large-fill dispensing is performed under laminar flow protection in a Class 10,000 cleanroom, using precision weighing equipment to weigh vial by vial for accurate fill. In the copper chelation reaction stage, we precisely control the molar ratio and reaction pH of GHK tripeptide and copper salt to ensure formation of a stable 1:1 chelate without free copper generation. Each batch undergoes appearance, copper content, solubility, pH, and microbial limit testing with COA report, providing stable reliable large-package raw material supply for customers' anti-aging and repair cosmetic formulation development.
