- pH Range: Optimal activity maintained between pH 5.0–7.0, compatible with most skin-friendly formulations.
Industry data from the 2023 Cosmetic Ingredient Review indicates that peptide-based serums with purity above 95% show 40% higher formulation stability compared to lower-grade alternatives, making purity a critical factor for bulk sourcing.
Manufacturing & Quality Control
The production of COSRX 6 Peptide Skin Booster Serum raw materials follows a rigorous multi-step process to ensure batch-to-batch consistency and compliance with international cosmetic standards. Each stage is documented for traceability and quality assurance.
Production Process
Synthesis begins with solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage and deprotection. The crude peptide is then purified via reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve target purity levels. Lyophilization yields a sterile, free-flowing powder suitable for bulk handling.
Quality Control Measures
Every batch undergoes third-party testing for identity, purity, heavy metals, and microbial limits. Certificates of analysis (CoA) are provided with each shipment, detailing HPLC chromatograms, mass spectrometry confirmation, and endotoxin levels below 0.5 EU/mg.
- ISO 22716: Good Manufacturing Practices (GMP) certification for cosmetic ingredients.
- HPLC Purity: ≥98% with single impurity limits below 0.5%.
- Microbial Testing: Total aerobic microbial count <100 CFU/g, yeast and mold <10 CFU/g.
- Heavy Metals: Lead <10 ppm, arsenic <2 ppm, mercury <1 ppm.
- Stability Testing: Accelerated stability at 40°C/75% RH for 6 months confirms shelf life.
Commercial Application Scenarios
The COSRX 6 Peptide Skin Booster Serum raw material complex is versatile across multiple B2B channels, from cosmetic formulation to laboratory research. Understanding these applications helps buyers optimize their procurement strategy.
Cosmetic Formulation
Formulators incorporate this peptide blend at 1–5% w/w into anti-aging serums, moisturizers, and eye creams. Its water solubility allows direct addition to the water phase without emulsifiers, simplifying production. Brands targeting premium markets benefit from the multi-peptide synergy for skin firming claims.
Lab Research
Research laboratories use the serum complex for in vitro studies on collagen synthesis, elastin production, and fibroblast activity. The defined peptide composition ensures reproducible results in mechanistic studies and efficacy testing.
Bulk Wholesale Usage
Wholesale buyers source this material for private label manufacturing, contract filling, or distribution to smaller cosmetic companies. Minimum order quantities typically start at 1 kg, with custom packaging options available for OEM clients.

Bulk Purchase Selection Guide
When sourcing COSRX 6 Peptide Skin Booster Serum raw materials in bulk, buyers must navigate common pitfalls to ensure product quality and supply chain reliability. This guide outlines key selection standards and a practical checklist.
Common Pitfalls
Many buyers encounter issues with inconsistent purity, mislabeled peptide sequences, or lack of documentation. Low-cost suppliers may offer impure blends that compromise formulation stability and regulatory approval.
Selection Standards
Prioritize suppliers who provide full transparency on synthesis methods, purity data, and third-party test results. Request samples for in-house validation before committing to large orders. Verify that the peptide complex matches the specified composition of six peptides.
- Documentation: CoA, MSDS, and stability reports for each batch.
- Lead Time: Standard 2–4 weeks for bulk orders; confirm capacity for urgent needs.
- Packaging: Sealed, light-protected containers with desiccant for moisture control.
- Price Benchmark: Compare cost per gram based on purity and peptide count, not just total weight.
- Supplier Reputation: Check industry reviews, trade show participation, and client references.
Core Product Advantages
The COSRX 6 Peptide Skin Booster Serum raw material offers distinct benefits for B2B buyers focused on quality, performance, and cost efficiency. These advantages make it a preferred choice for professional cosmetic and lab applications.
Purity and Stability
With ≥98% HPLC purity, this peptide complex minimizes side reactions and degradation in formulations. Stability data supports a 24-month shelf life under recommended storage, reducing waste and ensuring consistent product performance.
Cost Performance
Bulk pricing for this multi-peptide blend is competitive with single-peptide alternatives, offering better value through synergistic effects. Lower usage rates (1–3% w/w) further reduce per-unit formulation costs.
Technical Support
Suppliers provide formulation guidance, stability testing support, and regulatory documentation to streamline product development. This reduces R&D time and helps buyers achieve faster market entry.
Frequently Asked Questions
Q1: What is the recommended storage condition for bulk COSRX 6 Peptide Skin Booster Serum raw material?
Store at 2–8°C in a sealed, light-resistant container. Avoid exposure to moisture and temperatures above 25°C to maintain peptide integrity. Bulk containers should be used within 30 days of opening if not resealed properly.
Q2: Can this peptide complex be used in anhydrous formulations?
No, the peptides are water-soluble and require an aqueous phase for activity. For anhydrous systems, consider encapsulation or pre-dissolving in a small amount of water before incorporation into oil-based bases.
Q3: How does the six-peptide blend compare to copper peptide alone?
The six-peptide blend offers broader skin benefits, including collagen support, elastin stimulation, and barrier repair, whereas copper peptide primarily targets wound healing. The multi-peptide approach provides more comprehensive anti-aging effects in a single ingredient.
