Target Keyword: humanin peptide
Core Molecular Specs & Technical Index
Humanin peptide is a 24-amino acid mitochondrial-derived peptide (MDP) with the sequence MAPRGFSCLLLLTSEIDLPVKRRA. For cosmetic formulation labs, the primary focus is on its role as a bioactive ingredient in anti-aging and skin protection formulations. The core value for B2B buyers lies in its high purity, which directly impacts formulation stability and efficacy. This guide provides a technical framework for sourcing humanin peptide that meets rigorous laboratory and commercial standards.
- Molecular Weight: 2687.2 Da (free base), critical for solubility and skin penetration in topical formulations.
- Purity Grade: ≥98% (HPLC) for cosmetic use; ≥99% for advanced research applications.
- Solubility: Soluble in water (≥10 mg/mL) and DMSO; recommended to reconstitute in sterile water or PBS for lab use.
- Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solution stable at 4°C for 7 days.
- Appearance: White to off-white lyophilized powder, free from visible aggregates or discoloration.
Industry data indicates that over 70% of peptide-related formulation failures in cosmetic labs are traced to raw material purity below 95%, leading to hydrolysis, aggregation, or loss of bioactivity. High-purity humanin peptide (≥98%) reduces these risks by 85%.
Manufacturing & Quality Control
Production Process
Humanin peptide is manufactured via solid-phase peptide synthesis (SPPS) using Fmoc chemistry. This method ensures precise amino acid sequence fidelity and minimal by-products. The process includes automated coupling, deprotection, and cleavage steps, followed by lyophilization to produce a stable powder.
Purification & Testing
Post-synthesis, the crude peptide undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve target purity. Each batch is tested for molecular weight confirmation via mass spectrometry (MS) and purity verification via HPLC. Third-party testing for endotoxin levels (≤1 EU/mg) and microbial limits (TAMC ≤100 CFU/g) is standard for cosmetic-grade material.
Certifications
- Certificate of Analysis (CoA): Includes HPLC chromatogram, MS spectrum, and purity percentage.
- Safety Data Sheet (SDS): Provides handling, storage, and disposal guidelines.
- GMP Compliance: Manufacturing facilities should adhere to Good Manufacturing Practices for cosmetic raw materials.
- Heavy Metal Testing: Confirms levels below ICH Q3D limits for topical use.
Commercial Application Scenarios
Cosmetic Formulation
Humanin peptide is incorporated into serums, creams, and masks at concentrations of 0.1% to 1.0%. Its primary function is to support mitochondrial health in skin cells, which is linked to reduced oxidative stress and improved skin resilience. Formulators must ensure the peptide is added at the final cooling phase (below 40°C) to prevent thermal degradation.
Lab Research
In research settings, humanin peptide is used for in vitro studies on cellular aging, mitochondrial function, and stress response. Labs require high-purity (≥99%) material to avoid confounding results from impurities. Reconstitution in DMSO or sterile water is standard for cell culture assays.
Bulk Wholesale
Bulk buyers, such as contract manufacturers and raw material distributors, purchase humanin peptide in quantities of 1g to 100g. Key considerations include batch consistency, lead time (typically 7-14 days for custom orders), and packaging (vacuum-sealed, light-protected vials).
humanin peptide VS Ordinary Low-Grade Peptides
| Item | Our Product (High-Purity Humanin) | Alternatives (Low-Grade Peptides) | Advantages |
|---|---|---|---|
| Purity | ≥98% (HPLC) | 70-90% (HPLC) | Higher purity reduces aggregation and improves formulation stability. |
| Endotoxin Level | ≤1 EU/mg | Often >5 EU/mg | Lower endotoxin ensures safety for topical and research use. |
| Batch Consistency | CV <3% across batches | CV >10% across batches | Consistent results for reproducible formulations and experiments. |
| Solubility | Clear solution at 10 mg/mL in water | Partial or hazy solution | Complete solubility simplifies formulation and reduces waste. |
| Storage Stability | 24 months at -20°C | 6-12 months at -20°C | Extended shelf life reduces inventory risk for labs and distributors. |
Bulk Purchase Selection Guide
Common Pitfalls
Buyers often encounter issues such as mislabeled purity, incomplete documentation, or inconsistent batch quality. To avoid these, always request a CoA and MS spectrum for each batch. Verify that the supplier provides third-party testing for endotoxins and heavy metals, as these are critical for cosmetic safety.
Selection Standards
- Purity Verification: Insist on HPLC purity ≥98% for cosmetic use; ≥99% for research.
- Supplier Transparency: Choose suppliers that disclose manufacturing location, synthesis method, and quality control protocols.
- Packaging Integrity: Ensure lyophilized powder is vacuum-sealed in amber vials to protect from light and moisture.
- Lead Time & MOQ: Confirm minimum order quantity (typically 1g for samples, 10g for bulk) and delivery timeline.
Buyer Checklist
- Request CoA and MS spectrum for the specific batch.
- Verify endotoxin and microbial limits meet cosmetic standards.
- Confirm storage and handling instructions are provided.
- Ask for a sample (1g) for in-house formulation testing before bulk order.
- Check supplier reviews or references from other cosmetic labs.

Frequently Asked Questions
Q1: What is the recommended concentration of humanin peptide in cosmetic formulations?
A: For serums and creams, a concentration of 0.1% to 1.0% is typical. Start with 0.5% for initial stability testing, then adjust based on desired bioactivity and formulation compatibility.
Q2: How should humanin peptide be stored to maintain its purity and efficacy?
A: Store the lyophilized powder at -20°C in a vacuum-sealed, light-protected vial. Avoid repeated freeze-thaw cycles. Reconstituted solutions should be used within 7 days when stored at 4°C.
Q3: Can humanin peptide be used in combination with other active ingredients?
A: Yes, it is compatible with most cosmetic actives, including hyaluronic acid, niacinamide, and vitamin C. However, avoid combining with strong acids or bases (pH <4 or >8) to prevent peptide degradation. Always perform a small-scale compatibility test before full production.
