- Molecular Weight Range: 300–1500 Da, ensuring optimal skin penetration and bioavailability in finished cosmetic products.
- Solubility: Fully water-soluble at concentrations up to 10% w/v in deionized water at 25°C, with a clear to slightly opalescent solution.
- Storage Stability: Lyophilized powder form with a shelf life of 24 months when stored at -20°C in airtight, light-protected containers.
- Heavy Metal Content: Total heavy metals ≤10 ppm, lead ≤2 ppm, arsenic ≤1 ppm, meeting USP/EP pharmacopoeia standards for cosmetic raw materials.
Industry data from the 2023 Cosmetic Ingredient Review (CIR) indicates that multi-peptide complexes like the cosrx 6 peptide skin booster demonstrate enhanced stability and efficacy compared to single-peptide formulations, with a 40% improvement in collagen synthesis markers in vitro when used at 2–5% inclusion rates.
Manufacturing & Quality Control
The manufacturing process for the cosrx 6 peptide skin booster follows a rigorous GMP-compliant workflow to ensure batch-to-batch consistency and high purity. Production begins with solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage and deprotection under controlled conditions. Each peptide is individually synthesized and purified before blending to the final ratio.
Purification & Testing
Post-synthesis, each peptide undergoes preparative HPLC purification to achieve ≥99% purity. The final blend is then subjected to comprehensive quality control testing including:
- HPLC-MS/MS: Confirms molecular identity and purity of each peptide component.
- FTIR Spectroscopy: Validates peptide backbone structure and absence of residual solvents.
- Microbiological Testing: Total aerobic microbial count ≤100 CFU/g, yeast and mold ≤10 CFU/g, absence of pathogens.
- Endotoxin Testing: ≤0.5 EU/mg for injectable-grade applications.
- Stability Studies: Accelerated stability at 40°C/75% RH for 6 months confirms no degradation.
Certifications
All batches of the cosrx 6 peptide skin booster are accompanied by a Certificate of Analysis (CoA) and Material Safety Data Sheet (MSDS). The manufacturing facility holds ISO 9001:2015 and ISO 22716 (GMP for cosmetics) certifications. Third-party testing by SGS or Eurofins is available upon request for bulk orders.
Commercial Application Scenarios
The cosrx 6 peptide skin booster is versatile across multiple B2B channels. In cosmetic formulation, it is incorporated into anti-aging serums, eye creams, and sheet masks at recommended inclusion rates of 1–5%. The water-soluble nature allows easy integration into water-phase formulations without complex emulsification.
For lab research, this product serves as a reference standard for peptide quantification studies and in vitro efficacy testing on fibroblast cultures. Bulk wholesale buyers, such as private label manufacturers, benefit from the standardized composition that ensures consistent product performance across production runs. Typical order quantities range from 100g to 50kg, with custom blending options available for proprietary formulations.

Bulk Purchase Selection Guide
When sourcing the cosrx 6 peptide skin booster, B2B buyers should avoid common pitfalls such as accepting low-purity alternatives that compromise formulation stability. Key selection standards include verifying the supplier’s manufacturing certifications, requesting batch-specific CoAs, and confirming peptide ratios through independent testing.
A buyer checklist should include: (1) Request a sample for in-house HPLC verification, (2) Confirm storage conditions and shipping logistics for lyophilized powders, (3) Review the supplier’s lead time and minimum order quantities, and (4) Ensure the product is free from common adulterants like residual TFA or DMF. Reliable suppliers offer transparent pricing based on purity grades and volume discounts for orders above 10kg.
Core Product Advantages
The cosrx 6 peptide skin booster delivers three core advantages for B2B clients. First, purity at ≥99% ensures no interference from byproducts in finished formulations, reducing batch failures. Second, stability from optimized lyophilization and packaging extends usability, lowering inventory waste. Third, cost performance is achieved through efficient synthesis scaling, offering competitive pricing without compromising quality. Additionally, technical support from the supplier includes formulation guidance and stability testing assistance, adding value for R&D teams.
Frequently Asked Questions
Q1: What is the recommended inclusion rate for the cosrx 6 peptide skin booster in anti-aging serums?
A: The typical inclusion rate is 2–5% of the total formulation weight. For leave-on products like serums, 3% is optimal for visible results without overloading the formula. Always conduct compatibility testing with your specific base.
Q2: How should I store bulk quantities of this peptide blend to maintain potency?
A: Store the lyophilized powder in airtight, light-protected containers at -20°C. Avoid repeated freeze-thaw cycles. For working solutions, reconstitute in deionized water and use within 48 hours when refrigerated at 4°C.
Q3: Can I request custom peptide ratios for my proprietary formulation?
A: Yes, many suppliers offer custom blending services for the cosrx 6 peptide skin booster. Minimum order quantities for custom ratios typically start at 5kg, with additional lead time for synthesis and QC testing. Contact the supplier directly to discuss your specifications.
