Core Molecular Specs & Technical Index
Argireline peptide, also known as Acetyl Hexapeptide-8, is a synthetic peptide widely utilized in the cosmetic and biotechnology sectors. It functions by modulating neurotransmitter release, offering a non-invasive approach to reducing the appearance of expression lines. For B2B buyers—including cosmetic manufacturers, contract labs, and raw material distributors—understanding the precise technical specifications is critical for formulation success and regulatory compliance.
- Molecular Formula & Weight: C34H60N14O12S with a molecular weight of approximately 888.98 g/mol. This structure ensures high stability in aqueous formulations.
- Purity Grade: Standard wholesale purity is ≥98% by HPLC. Premium grades offer ≥99% for advanced research and clinical-grade applications.
- Solubility Profile: Freely soluble in water and phosphate-buffered saline (PBS) at concentrations up to 10 mg/mL. Avoid organic solvents like ethanol or DMSO for cosmetic use.
- Storage Conditions: Lyophilized powder stored at -20°C maintains stability for 24 months. Reconstituted solutions must be used within 7 days when refrigerated at 2-8°C.
- pH Range: Optimal activity in formulations with pH 5.0–7.0. Outside this range, peptide degradation accelerates significantly.
Industry data from the 2023 Peptide Therapeutics Report indicates that over 78% of cosmetic peptide buyers prioritize HPLC purity certificates above 98% when sourcing argireline peptide wholesale. This standard directly correlates with batch-to-batch consistency in finished products.
Manufacturing & Quality Control
The production of high-grade argireline peptide involves solid-phase peptide synthesis (SPPS) followed by rigorous purification and analytical validation. Reputable manufacturers adhere to Good Manufacturing Practice (GMP) standards to ensure product safety and efficacy for commercial use.
Production Process
Synthesis begins with Fmoc chemistry on resin supports, building the peptide chain sequentially. After cleavage and deprotection, the crude peptide undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve target purity. This step removes truncated sequences and residual solvents.
Purification & Third-Party Testing
Post-synthesis, the peptide is lyophilized into a white powder. Independent laboratories conduct mass spectrometry (MS) for molecular weight confirmation and amino acid analysis for composition verification. Endotoxin levels are tested to ensure they remain below 0.5 EU/mg for cosmetic safety.
Certification Checklist
- Certificate of Analysis (CoA): Includes HPLC purity percentage, MS data, and residual solvent content.
- GMP Compliance: Verifies manufacturing under controlled environmental conditions.
- MSDS (Material Safety Data Sheet): Provides handling, storage, and toxicity information.
- Heavy Metal Analysis: Confirms levels below 10 ppm for lead, arsenic, and mercury.
- Microbiological Testing: Ensures total aerobic microbial count (TAMC) is less than 100 CFU/g.
Commercial Application Scenarios
Argireline peptide serves diverse commercial needs across the cosmetic and research industries. Its versatility makes it a staple ingredient for anti-aging formulations and laboratory studies on neuropeptide activity.
Cosmetic Formulation
In skincare products, argireline peptide is incorporated into serums, creams, and masks at concentrations ranging from 5% to 10% of the active phase. It targets periorbital and forehead lines, offering a non-invasive alternative to injectable treatments. Manufacturers value its compatibility with hyaluronic acid and vitamin C in water-based systems.
Lab Research
Research institutions use argireline peptide to study muscle contraction pathways and neurotransmitter inhibition. It serves as a model compound for developing new neuromodulatory peptides. Bulk orders for lab use often require higher purity (≥99%) and smaller batch sizes for controlled experiments.
Bulk Wholesale Usage
Wholesale buyers typically order argireline peptide in quantities of 1 kg to 100 kg for large-scale production. These orders benefit from custom packaging, such as vacuum-sealed aluminum bags with desiccants, to maintain stability during transit. Price negotiations often include volume discounts and expedited shipping for time-sensitive projects.

Bulk Purchase Selection Guide
When sourcing argireline peptide wholesale, buyers must navigate common pitfalls to ensure product quality and cost efficiency. This guide outlines key selection standards and a practical checklist for procurement teams.
Common Pitfalls
One frequent issue is accepting purity claims without third-party verification. Some suppliers provide CoA from in-house labs, which may lack objectivity. Another pitfall is overlooking storage conditions during shipping; peptides exposed to temperatures above 25°C for extended periods degrade rapidly. Additionally, buyers sometimes prioritize price over certification, leading to formulations that fail stability tests.
Selection Standards
Prioritize suppliers who offer independent HPLC analysis from accredited laboratories. Verify that the peptide is packaged in airtight, light-resistant containers with desiccants. Request samples for in-house testing before committing to large orders. For cosmetic use, ensure the supplier provides a cosmetic-grade certificate, which includes microbiological and heavy metal data.
Buyer Checklist
- Request a full CoA with HPLC chromatogram and MS spectrum.
- Confirm GMP certification for the manufacturing facility.
- Test solubility in your target formulation base before bulk purchase.
- Evaluate shipping conditions to maintain cold chain integrity.
- Compare pricing per gram at different purity levels to optimize cost.

Frequently Asked Questions
Q: What is the minimum order quantity for argireline peptide wholesale?
Most suppliers require a minimum of 1 kg for wholesale pricing. However, some offer sample sizes of 10 g to 100 g for initial testing. For large-scale production, orders of 5 kg or more typically qualify for volume discounts and expedited shipping.
Q: How do I verify the purity of argireline peptide from a new supplier?
Request a Certificate of Analysis (CoA) that includes an HPLC chromatogram and mass spectrometry data. Cross-check the reported purity with an independent third-party lab test. Reputable suppliers will provide this documentation without hesitation and may offer a sample for your own verification.
Q: Can argireline peptide be used in oil-based formulations?
Argireline peptide is water-soluble and not compatible with pure oil systems. For oil-based formulations, it must be encapsulated in liposomes or incorporated into water-in-oil emulsions. Consult with your supplier for specific encapsulation protocols to maintain peptide stability and efficacy.
