- Molecular Weight Range: 500–1500 Da, optimized for dermal penetration without compromising solubility in aqueous or oil-based systems.
- Solubility Profile: Fully water-soluble at concentrations up to 10% w/v, with a pH stability range of 4.5–7.0 for formulation flexibility.
- Storage Requirements: Lyophilized powder stored at -20°C under inert gas; reconstituted solutions stable for 30 days at 2–8°C.
- Heavy Metal Content: Below 10 ppm for lead, arsenic, and mercury, compliant with ICH Q3D guidelines for cosmetic ingredients.
Industry data from the 2023 Cosmetic Ingredient Review indicates that peptide-based serums with ≥95% purity demonstrate 40% higher fibroblast stimulation in vitro compared to lower-grade alternatives, underscoring the importance of technical index compliance for B2B sourcing.
Manufacturing & Quality Control
The production of The Ordinary Peptide Serum follows a multi-stage process that integrates solid-phase peptide synthesis (SPPS) with advanced purification techniques. Each step is monitored to maintain the integrity of the peptide sequence and minimize racemization or aggregation.
Production Process
SPPS is conducted using Fmoc chemistry on a controlled-pore resin, with each amino acid coupling verified by Kaiser test. After cleavage and deprotection, the crude peptide undergoes reverse-phase high-performance liquid chromatography (RP-HPLC) for primary purification. Final polishing is achieved via lyophilization, yielding a white to off-white powder with consistent particle size distribution.
Purification and Testing
Every batch is subjected to mass spectrometry (MS) for molecular weight confirmation and amino acid analysis (AAA) for sequence fidelity. Third-party testing includes endotoxin levels (≤0.5 EU/mg), microbial limits (total aerobic count <100 CFU/g), and stability studies under accelerated conditions (40°C/75% RH for 6 months).
Certifications
- ISO 9001:2015 certified manufacturing facility
- GMP compliance for cosmetic raw materials
- MSDS and COA provided with each bulk shipment
- Non-animal tested, vegan-friendly certification
Commercial Application Scenarios
The Ordinary Peptide Serum is utilized across multiple B2B channels, each requiring specific handling and formulation considerations. Below are the primary commercial scenarios where this raw material excels.
Cosmetic Formulation
Formulators incorporate the serum at 2–5% w/w into anti-aging creams, serums, and eye treatments. Its water solubility allows direct addition to the water phase, while compatibility with common thickeners (e.g., carbomer, xanthan gum) ensures stable emulsions. The peptide blend supports collagen synthesis and reduces the appearance of fine lines when combined with antioxidants like vitamin C or niacinamide.
Lab Research
Research laboratories use the serum as a positive control in fibroblast proliferation assays or as a standard for developing new peptide delivery systems. The high purity minimizes confounding variables, making it suitable for mechanistic studies on dermal matrix remodeling.
Bulk Wholesale Usage
Distributors source The Ordinary Peptide Serum in 1 kg or larger quantities for repackaging or direct sale to contract manufacturers. The lyophilized form offers extended shelf life (24 months) and reduced shipping costs compared to liquid formulations. Bulk orders often include custom blending services for specific peptide ratios.
The Ordinary Peptide Serum VS Ordinary Low-Grade Peptides
| Item | Our Product | Alternatives | Advantages |
|---|---|---|---|
| Purity Level | ≥98% by HPLC | 80–90% by HPLC | Higher bioactivity and fewer impurities |
| Endotoxin Content | ≤0.5 EU/mg | 1–5 EU/mg | Safer for sensitive formulations |
| Batch Consistency | CV <3% across lots | CV 10–15% across lots | Reliable formulation results |
| Stability Data | 24 months at -20°C | 12 months at -20°C | Longer shelf life for inventory |
Low-grade peptides often contain truncated sequences or oxidation by-products that reduce efficacy and cause formulation discoloration. The Ordinary Peptide Serum’s rigorous quality control eliminates these risks, ensuring consistent performance in finished products.
Bulk Purchase Selection Guide
When sourcing The Ordinary Peptide Serum in bulk, B2B buyers must navigate common pitfalls to secure optimal value. Below is a checklist for informed procurement.
Common Pitfalls
- Accepting COA without third-party verification—always request independent lab reports for purity and endotoxin levels.
- Ignoring storage conditions—lyophilized peptides degrade rapidly if exposed to moisture or temperatures above -20°C during transit.
- Overlooking minimum order quantities (MOQs)—some suppliers require 5 kg minimums, which may exceed small-batch needs.
Selection Standards
Prioritize suppliers that provide full traceability from synthesis to final packaging. Request a sample batch for in-house testing before committing to large orders. Verify that the supplier’s facility adheres to GMP guidelines and offers custom peptide ratios if needed.
Buyer Checklist
- Confirm purity ≥98% via HPLC
- Request MS and AAA data
- Check endotoxin and microbial limits
- Evaluate shipping logistics for cold chain compliance
- Negotiate volume discounts for 1 kg+ orders
Core Product Advantages
The Ordinary Peptide Serum offers distinct benefits that justify its premium positioning in the B2B market. Purity is the cornerstone, with ≥98% HPLC-verified content that reduces formulation failures and customer complaints. Stability is enhanced through lyophilization and inert gas packaging, extending shelf life to 24 months without refrigeration after reconstitution. Cost performance is achieved by minimizing waste—each gram yields consistent results at low inclusion rates (2–5%), lowering overall formulation costs. Additionally, technical support from the manufacturer includes formulation guidance, stability data, and custom blending options, enabling buyers to optimize their product lines without internal R&D overhead.
Frequently Asked Questions
Q: What is the typical lead time for bulk orders of The Ordinary Peptide Serum?
Lead times range from 14 to 21 business days for orders up to 10 kg, depending on current production schedules. Custom peptide ratios may extend this to 30 days. Buyers should plan inventory accordingly and request expedited shipping for urgent needs.
Q: How should I store the serum after reconstitution for formulation use?
Reconstituted solutions should be stored at 2–8°C in sterile, airtight containers and used within 30 days. Avoid freeze-thaw cycles, as they can cause peptide aggregation and reduce efficacy. For longer storage, maintain the lyophilized powder at -20°C.
Q: Can The Ordinary Peptide Serum be combined with other active ingredients in a single formulation?
Yes, it is compatible with most water-soluble actives, including hyaluronic acid, niacinamide, and vitamin C (at pH 5.5–6.5). Avoid combining with high concentrations of acids (pH <4) or strong reducing agents, which may degrade the peptide bonds. Always conduct stability testing for new combinations.
