Industry data from the 2023 Cosmetic Ingredient Review indicates that peptide-based hair density formulations with ≥95% purity show 40% higher stability in accelerated aging tests compared to lower-grade alternatives, reducing batch failure rates for manufacturers.
Manufacturing & Quality Control
The production of The Ordinary Multi Peptide Serum for Hair Density follows a stringent manufacturing protocol to ensure batch-to-batch consistency. The process begins with solid-phase peptide synthesis (SPPS) for individual peptides, followed by controlled blending under nitrogen atmosphere to prevent oxidation. Purification employs reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve the required purity threshold. Third-party testing is conducted by ISO 17025-accredited laboratories for heavy metals, microbial limits, and peptide content verification. Certifications include:
- ISO 9001:2015 for quality management systems in production.
- GMP Certification (Good Manufacturing Practice) for cosmetic ingredient handling.
- MSDS (Material Safety Data Sheet) compliance for safe handling and transport.
- Certificate of Analysis (CoA) provided with each batch, detailing purity, pH, and microbial counts.
- Non-GMO and Vegan Certification for plant-derived components like red clover extract.
Commercial Application Scenarios
The Ordinary Multi Peptide Serum for Hair Density serves multiple B2B applications across the cosmetic and research industries. In cosmetic formulation, it is used as a functional active in leave-in scalp serums, shampoos, and conditioners at concentrations of 2–5% to enhance product claims around hair density. For lab research, it provides a standardized peptide matrix for in vitro studies on dermal papilla cell proliferation and hair follicle cycling. Bulk wholesale buyers, such as private label manufacturers, integrate this serum into custom blends for salon-grade hair care lines, leveraging its compatibility with other actives like biotin and caffeine. Typical usage cases include:
- Scalp Treatment Serums: Formulated at 3% concentration with hyaluronic acid for hydration.
- Hair Thickening Shampoos: Added at 1.5% in surfactant systems for daily use.
- Research Kits: Supplied in 100 mL aliquots for academic and clinical trials.
The Ordinary Multi Peptide Serum for Hair Density VS Ordinary Low-Grade Peptides
| Item | Our Product | Alternatives | Advantages |
|---|---|---|---|
| Purity Level | ≥98% by HPLC | 80–90% by basic filtration | Higher purity reduces formulation interference and improves efficacy |
| Stability | 24-month shelf life at 2–8°C | 6–12 months with frequent degradation | Longer stability lowers inventory waste for bulk buyers |
| Certification | ISO 9001, GMP, Non-GMO | Often no third-party certification | Full traceability and regulatory compliance for global markets |
| Cost per Liter | Competitive at $150–$200 (bulk) | $80–$120 but with lower performance | Better cost-performance ratio due to reduced rework needs |
Bulk Purchase Selection Guide
When sourcing The Ordinary Multi Peptide Serum for Hair Density in bulk, professional buyers must navigate common pitfalls to ensure product integrity. One frequent issue is mislabeling of peptide concentrations, where suppliers claim high purity but deliver diluted blends. To avoid this, always request a Certificate of Analysis (CoA) from the manufacturer and verify HPLC data independently. Another pitfall is improper storage during transit, which can degrade peptides; insist on cold-chain shipping with temperature logs. Selection standards include checking for ISO 17025 lab reports, confirming batch numbers, and evaluating supplier history in cosmetic raw materials. A buyer checklist should cover:
- Verify peptide content via third-party HPLC testing.
- Request stability data under accelerated conditions (40°C/75% RH for 3 months).
- Confirm packaging: amber glass or HDPE containers with nitrogen flush.
- Audit supplier for GMP and ISO certifications.
- Negotiate minimum order quantities (MOQs) that align with production cycles.

Frequently Asked Questions
Q1: What is the recommended concentration of The Ordinary Multi Peptide Serum for Hair Density in cosmetic formulations?
For leave-in serums, a concentration of 2–5% is typical to achieve hair density benefits without overloading the formula. In rinse-off products like shampoos, 1–2% is sufficient due to shorter contact time. Always conduct stability tests at your target pH (4.5–6.5) to confirm compatibility.
Q2: How should I verify the authenticity of bulk peptide serum shipments?
Request a Certificate of Analysis (CoA) with each batch, including HPLC purity data, microbial limits, and pH. Cross-reference the batch number with the manufacturer's database. For high-value orders, consider independent third-party testing through an ISO 17025 lab to confirm peptide content and absence of contaminants.
Q3: Can this serum be combined with other active ingredients like retinol or niacinamide?
Yes, it is compatible with most water-soluble actives, including niacinamide and hyaluronic acid. Avoid combining with strong oxidizing agents or high concentrations of ethanol, which may degrade peptides. Perform a small-scale compatibility test at 40°C for 48 hours to check for precipitation or color changes before full production.
