Formulation Features
Consistent Synthetic Tripeptide
Every lot is released against the same Ala-His-Lys-Cu identity checked by mass-spec, giving formulators a reproducible copper peptide instead of a shifting blend.
Blue-Violet Color as a QC Cue
Incoming QC can use the color as a flag — a pale or off-white powder means the copper is not fully bound and the batch should be refused.
Water-Soluble for Aqueous Systems
It goes into water-based shampoos, scalp serums and tonics at ≥ 100 mg/mL without needing a solubilizer or heating stage.
Scalp & Hair-Care Positioning
Built for hair-care and scalp formats at 0.05%–0.5%; for external topical use in finished cosmetics only.
Applications
Hair Serums & Scalp Essence
A leave-on drop format where the peptide sits on the scalp; water-soluble so it blends into the serum without cloudiness.
Shampoo & Conditioner
Rinse-off washes take it as a scalp-care additive at the recommended low inclusion.
Hair Masks & Tonics
Conditioning masks and daily tonics carry it as a leave-on hair-care component.
Leave-on Scalp Treatments
Daily scalp treatments keep the peptide on skin as the finished cosmetic step.
Private-Label & OEM Lines
We set grade, pack size and label files to a brand’s own hair-care specification.
