Basic Properties and Molecular Characteristics
Reda peptide is supplied as a lyophilized white powder with a molecular weight typically ranging between 800 and 1500 Daltons, depending on the specific sequence variant. It exhibits high solubility in water and standard buffer solutions, making it ideal for incorporation into aqueous cosmetic bases. The peptide is stable under recommended storage conditions of -20°C to -80°C for long-term preservation, with a shelf life of 24 to 36 months when properly handled.
Purity and Quality Indexes
- Purity Level: Minimum 98% as determined by HPLC analysis, with premium grades reaching 99.5% for research applications.
- Peptide Content: Typically 80-90% net peptide content, with the remainder being counterions and residual moisture.
- Solubility: Fully soluble in water at concentrations up to 10 mg/mL, with optimal solubility in phosphate-buffered saline.
- Storage Conditions: Store at -20°C for up to 2 years; avoid repeated freeze-thaw cycles to maintain stability.
- Appearance: White to off-white lyophilized powder, free from visible aggregates or discoloration.
Industry data indicates that over 70% of cosmetic formulation failures are attributed to peptide purity below 95%, leading to reduced efficacy and stability issues. High-purity reda peptide at 98%+ significantly minimizes these risks.
Manufacturing & Quality Control
The production of reda peptide follows a stringent solid-phase peptide synthesis (SPPS) process, ensuring high yield and minimal impurities. Each batch undergoes rigorous quality control to meet international standards for cosmetic raw materials.
Production Process
The synthesis begins with the sequential addition of protected amino acids to a solid resin support. After chain assembly, the peptide is cleaved from the resin and deprotected using trifluoroacetic acid (TFA). Crude peptide is then purified via preparative high-performance liquid chromatography (HPLC) to achieve the desired purity level. The final product is lyophilized and packaged under inert nitrogen atmosphere to prevent oxidation.
Quality Control and Third-Party Testing
Every batch of reda peptide is subjected to comprehensive testing, including analytical HPLC for purity verification, mass spectrometry for molecular weight confirmation, and amino acid analysis for sequence integrity. Third-party certificates of analysis (CoA) are provided with each shipment, ensuring transparency and traceability.
- HPLC Purity: ≥98% with single impurity peaks below 0.5%.
- Mass Spectrometry: Confirmed molecular weight within ±0.5 Da of theoretical value.
- Endotoxin Testing: ≤0.5 EU/mg for cosmetic grade, ≤0.1 EU/mg for research grade.
- Microbiological Testing: Total aerobic microbial count <100 CFU/g, absence of pathogens.
- Certifications: ISO 9001:2015, GMP compliance, and MSDS documentation available.
Commercial Application Scenarios
Reda peptide is widely used in cosmetic formulation labs, research institutions, and bulk wholesale markets. Its versatility and high purity make it suitable for a range of applications.
Cosmetic Formulation
In anti-aging serums, eye creams, and moisturizers, reda peptide acts as a signaling peptide that promotes collagen synthesis and skin firmness. Formulators typically incorporate it at concentrations of 0.1% to 1.0% in water-based or emulsion systems. The peptide's stability in formulations is enhanced by using antioxidants and chelating agents to prevent degradation.
Lab Research
Research laboratories use reda peptide for in vitro studies on fibroblast activity, wound healing models, and skin barrier function. Its high purity ensures reproducible results in cell culture assays and biochemical analyses.
Bulk Wholesale Usage
Bulk buyers, including contract manufacturers and raw material distributors, source reda peptide in quantities ranging from 10 grams to 10 kilograms. The product is supplied in sealed, light-protected containers with desiccants to maintain stability during transit and storage.

Bulk Purchase Selection Guide
When sourcing reda peptide in bulk, buyers must avoid common pitfalls to ensure product quality and value. This guide outlines key selection standards and a practical checklist for procurement professionals.
Common Pitfalls
One frequent mistake is prioritizing price over purity, which leads to formulations with reduced efficacy and stability issues. Another is neglecting to request certificates of analysis (CoA) for each batch, resulting in inconsistent quality. Additionally, improper storage during transit can degrade the peptide before it reaches the lab.
Selection Standards
Always verify the supplier's manufacturing certifications, such as ISO 9001 or GMP compliance. Request a sample for in-house testing before committing to large orders. Confirm that the peptide is packaged in airtight, light-resistant containers with desiccants. Ensure the supplier provides detailed CoA including HPLC chromatograms, mass spectrometry data, and microbiological test results.
Buyer Checklist
- Supplier Credentials: Check for ISO, GMP, and third-party audit reports.
- Sample Testing: Request a 1-gram sample for purity and solubility verification.
- Documentation: Obtain CoA, MSDS, and stability data for each batch.
- Packaging: Ensure double-bagging with desiccant and nitrogen flush.
- Shipping: Use cold chain logistics with temperature monitoring.
