Copper Tripeptide-34 ●
TL;DR. This ingredient is used as a skin-conditioning cosmetic active, typically added to serums, creams, and eye products to support a smoother, firmer-looking skin feel. It is not a preservative, surfactant, or UV filter, and its role is mainly signal-oriented skin care positioning at low use levels.
What does Copper Tripeptide-34 do in a cosmetic formula?
This ingredient is used as a skin-conditioning cosmetic active, typically added to serums, creams, and eye products to support a smoother, firmer-looking skin feel. It is not a preservative, surfactant, or UV filter, and its role is mainly signal-oriented skin care positioning at low use levels.
Is Copper Tripeptide-34 clean?
From a clean-beauty perspective, it is not a common restricted-list ingredient and is generally used at very low concentrations. DARE flags it as more complex than basic humectants because public data is thinner, and sensitivity depends on dose, delivery system, and formula context.
Is Copper Tripeptide-34 sustainable?
This material is typically made through specialty peptide synthesis and metal complexation rather than direct agricultural extraction. Its use level is very low, but the synthesis, purification, and metal ion content make its sustainability profile less straightforward than simple plant-derived or readily biodegradable basics.
Is Copper Tripeptide-34 COSMOS-approved?
It is not a clear fit for COSMOS-organic, and COSMOS-natural acceptance would depend on supplier documentation and certifier review because synthetic peptide complexes are often outside standard natural-origin pathways. Its Green Chemistry profile is mixed, with low dosage and likely peptide breakdown on one side, and solvent-intensive synthesis and purification on the other.
How does Copper Tripeptide-34 work chemically?
The molecule is a coordination complex in which a trace metal ion is bound by a three-amino-acid peptide, giving it different behavior from either the free peptide or the free mineral salt. It is usually supplied as a dilute aqueous or glycolic solution, formulated at low active levels, and is best kept away from strong chelators, strong oxidizers, and extreme pH to preserve complex stability.
