Core Molecular Specs & Technical Index
For cosmetic formulation labs and research institutions, the mt-1 peptide (Melanotan-1, also known as Afamelanotide) represents a high-value synthetic peptide with specific purity requirements. This alpha-melanocyte-stimulating hormone (α-MSH) analog is primarily sourced for research into pigmentation modulation and photoprotection mechanisms. The core value for B2B buyers lies in securing a consistent, high-purity raw material that meets rigorous laboratory standards for reproducible experimental outcomes and stable formulation development.
- Molecular Formula & Weight: C78H111N21O19, with a molecular weight of approximately 1646.9 g/mol. This dictates solubility and compatibility with common cosmetic solvents.
- Purity Specification: Minimum 98% purity by HPLC (High-Performance Liquid Chromatography) is the industry baseline for research-grade mt-1 peptide. Premium grades offer 99%+ for advanced formulation work.
- Solubility Profile: Freely soluble in water and saline solutions. For cosmetic formulations, it is typically dissolved in sterile water or buffered solutions at concentrations between 1-10 mg/mL.
- Storage Conditions: Lyophilized powder must be stored at -20°C or below, protected from light and moisture. Reconstituted solutions should be used immediately or stored at 2-8°C for no more than 72 hours.
- Appearance & Form: White to off-white lyophilized powder, typically supplied in sterile, vacuum-sealed vials with desiccant. Each batch should include a Certificate of Analysis (CoA).
Industry data from the Peptide Therapeutics Foundation indicates that over 85% of cosmetic peptide formulation failures are directly linked to raw material purity below 97% or improper storage conditions. Labs sourcing mt-1 peptide with verified HPLC purity above 98% report 40% higher reproducibility in melanogenesis studies.
Manufacturing & Quality Control
The production of high-grade mt-1 peptide follows a strict Good Manufacturing Practice (GMP) framework. Solid-phase peptide synthesis (SPPS) is the standard method, utilizing Fmoc chemistry to assemble the 13-amino acid sequence. Post-synthesis, the crude peptide undergoes cleavage and deprotection before entering purification stages.
Quality control protocols are non-negotiable for B2B buyers. Every batch must pass three independent verification steps: HPLC for purity assessment, mass spectrometry (MS) for molecular weight confirmation, and amino acid analysis for sequence integrity. Third-party testing by ISO 17025 accredited laboratories adds an extra layer of assurance for cosmetic formulation labs.
- Purification Process: Preparative HPLC using C18 reverse-phase columns, achieving >98% purity with endotoxin levels below 0.5 EU/mg.
- Analytical Testing: Each batch includes HPLC chromatogram, MS spectrum, and residual solvent analysis (below ICH Q3C limits).
- Stability Studies: Accelerated stability testing at 40°C/75% RH for 4 weeks confirms shelf life of 24-36 months when stored correctly.
- Certification Requirements: GMP compliance certificate, MSDS (Material Safety Data Sheet), and non-animal origin declaration are mandatory for cosmetic ingredient sourcing.
- Batch Traceability: Full chain-of-custody documentation from raw material procurement to final packaging, including batch numbers and expiry dates.
Commercial Application Scenarios
The mt-1 peptide serves distinct commercial roles across cosmetic formulation, laboratory research, and bulk wholesale markets. Each application demands specific purity grades and documentation packages.
In cosmetic formulation, mt-1 peptide is incorporated into topical serums and creams at concentrations between 0.01% and 0.1%. Formulators require peptide with verified stability in emulsion systems and compatibility with common preservatives like phenoxyethanol. The peptide's ability to stimulate melanogenesis makes it valuable for self-tanning products and photoprotective formulations.
For laboratory research, mt-1 peptide is used in cell culture studies investigating melanocyte function, UV response pathways, and pigmentation disorders. Research-grade material (98%+ purity) is essential for reproducible in vitro and ex vivo experiments. Bulk wholesale buyers, typically peptide distributors or large-scale cosmetic manufacturers, require consistent batch-to-batch quality, volume discounts, and comprehensive regulatory documentation for international shipping.

Bulk Purchase Selection Guide
When sourcing mt-1 peptide for bulk procurement, cosmetic formulation labs must navigate common pitfalls to ensure material quality and regulatory compliance. The following selection criteria help buyers make informed decisions.
Common pitfalls include accepting peptides without third-party HPLC verification, ignoring endotoxin specifications, and failing to verify storage conditions during transit. Buyers should always request a sample batch for in-house testing before committing to large-volume orders. Additionally, verify that the supplier provides full traceability documentation, including batch numbers and manufacturing dates.
- Purity Verification: Request HPLC chromatogram with peak area percentage and retention time matching reference standard.
- Supplier Credentials: Check for GMP certification, ISO 9001 quality management, and membership in industry associations like the Peptide Therapeutics Foundation.
- Shipping Conditions: Ensure lyophilized peptide is shipped with dry ice or ice packs, with temperature monitoring during transit.
- Minimum Order Quantities: Typical MOQ for mt-1 peptide ranges from 1 gram to 100 grams, with volume discounts at 10g+ and 100g+ tiers.
- Regulatory Documentation: Request MSDS, non-animal origin certificate, and country-specific import documentation (e.g., TSCA for USA, REACH for EU).

Frequently Asked Questions
Q1: What is the minimum purity required for mt-1 peptide in cosmetic formulation research?
A: For cosmetic formulation labs, the minimum acceptable purity is 98% by HPLC. This ensures minimal impurity interference in formulation stability studies and biological assays. Premium-grade material at 99%+ purity is recommended for advanced research involving cell culture or in vivo models.
Q2: How should mt-1 peptide be stored after reconstitution for laboratory use?
A: Reconstituted mt-1 peptide should be stored at 2-8°C and used within 72 hours. For longer storage, aliquot the solution and freeze at -20°C for up to 30 days. Avoid repeated freeze-thaw cycles, as this can degrade the peptide and reduce biological activity.
