Cosmetic Peptide Supply
Cosmetic-grade peptide raw materials for skincare and personal-care manufacturers, supplied with INCI naming.
QIANMIAO supplies cosmetic-grade peptide raw materials to skincare and personal-care manufacturers worldwide. Signal peptides, carrier peptides and neurotransmitter-inhibiting peptides are produced in-house at our ISO 9001 certified facility and released against the same specifications as our research-grade lines.
Cosmetic formulators need more than a vial of powder. We supply INCI naming, solubility and stability guidance, and recommended use levels, so the material moves straight into your formulation work instead of stalling in evaluation.
Peptide Classes We Supply
Our cosmetic line covers the peptide families most used in anti-aging, brightening and barrier-repair formulations.
- Signal peptides — GHK-Cu and Palmitoyl tripeptides that support collagen and matrix synthesis research.
- Neurotransmitter-inhibiting — SNAP-8 (Acetyl Octapeptide-3) and Argireline-type sequences.
- Melanocortin peptides — Melanotan I and II for pigmentation research.
- Repair peptides — KPV and copper-complexed tripeptides for barrier and soothing applications.
Formulation Support
Peptides are sensitive to pH, chelators and preservatives. We supply the data your formulator needs before the first trial batch.
- INCI naming — supplied with every cosmetic-grade product for label compliance.
- Solubility guidance — recommended solvent systems and typical use levels.
- Stability data — pH and temperature stability ranges available on request.
- Documentation — COA, HPLC chromatogram, MS spectrum and SDS with every batch.

Frequently Asked Questions
Do you supply INCI names for label compliance?
Yes. Every cosmetic-grade product ships with its INCI name so your regulatory team can build the label without chasing us for it.
Can you match a purity specification our formulation requires?
Our catalog standard is ≥99% by HPLC. If your specification differs, send it with your enquiry and we will quote against it.
Are free samples available for formulation trials?
We provide free COA samples for evaluation, and small physical quantities at competitive pricing for trial batches.
