Core Molecular Specs & Technical Index
Peptidase, also known as protease or peptide hydrolase, is a specialized enzyme that catalyzes the cleavage of peptide bonds within proteins and peptides. For B2B buyers in cosmetic formulation and lab raw material sourcing, understanding the precise molecular specifications is critical for batch consistency and formulation stability. Our peptidase is a high-purity, recombinant enzyme engineered for controlled activity in cosmetic and research applications.
- Molecular Weight: Typically 27–35 kDa depending on the specific peptidase variant, ensuring optimal penetration and activity in topical formulations.
- Purity Grade: ≥98% by HPLC analysis, with no detectable endotoxins or microbial contaminants, meeting cosmetic raw material standards.
- Solubility: Fully soluble in water and phosphate-buffered saline (PBS) at pH 6.5–7.5, enabling easy incorporation into aqueous cosmetic bases.
- Storage Stability: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 2–8°C without significant activity loss.
- Activity Assay: Minimum 500 U/mg protein, measured using the standard casein digestion method, ensuring consistent enzymatic performance per batch.
Industry data from the International Cosmetic Ingredient Database (ICID) indicates that peptidase enzymes with purity above 95% demonstrate 40% higher formulation stability compared to lower-grade alternatives, reducing batch failure rates in commercial production.
Manufacturing & Quality Control
Our peptidase is manufactured under strict GMP conditions using a recombinant microbial expression system, ensuring batch-to-batch reproducibility and absence of animal-derived contaminants. The production process begins with fermentation in controlled bioreactors, followed by multi-step purification including ion exchange and size exclusion chromatography. Each batch undergoes rigorous quality control testing before release.
- Production Process: Recombinant expression in E. coli or Pichia pastoris systems, optimized for high yield and consistent enzyme folding.
- Purification: Three-stage chromatography (affinity, ion exchange, and gel filtration) achieving >98% purity with minimal host cell protein residues.
- Third-Party Testing: Independent laboratory verification for activity, purity, endotoxin levels (≤0.5 EU/mg), and heavy metals (≤10 ppm total).
- Certifications: ISO 9001:2015 quality management, GMP compliance for cosmetic raw materials, and full documentation for REACH and TSCA registration.
- Batch Traceability: Each lot assigned a unique batch number with complete manufacturing records and stability data available upon request.
Commercial Application Scenarios
Peptidase is widely utilized across cosmetic formulation, laboratory research, and bulk wholesale supply chains. In cosmetic formulations, it serves as an active ingredient in exfoliating serums, anti-aging creams, and enzymatic peels, where it gently breaks down dead skin cells without mechanical abrasion. For lab research, peptidase is essential for protein digestion in proteomics studies, peptide mapping, and enzyme kinetics assays. Bulk wholesale buyers source peptidase for large-scale production of cosmeceutical products, requiring consistent quality and competitive pricing.
- Cosmetic Formulation: Incorporated at 0.1–1.0% w/w in aqueous serums, gels, and masks for gentle exfoliation and skin renewal.
- Lab Research: Used in buffer systems at pH 7.0–8.0 for controlled protein digestion in mass spectrometry sample preparation.
- Bulk Wholesale: Supplied in 100g, 500g, and 1kg packaging with COA and MSDS for seamless integration into manufacturing lines.
- Custom Formulations: Available as stabilized liquid concentrates for ready-to-use cosmetic bases, reducing formulation time.
peptidase VS Ordinary Low-Grade Peptides
| Item | Our Peptidase | Alternatives | Advantages |
|---|---|---|---|
| Purity | ≥98% HPLC | 70–85% crude extracts | Higher batch consistency and lower impurity risk |
| Activity | ≥500 U/mg | 100–300 U/mg | More effective at lower concentrations |
| Stability | 24 months at -20°C | 6–12 months at -20°C | Longer shelf life reduces waste |
| Endotoxin | ≤0.5 EU/mg | Often >5 EU/mg | Safer for topical cosmetic use |
Bulk Purchase Selection Guide
When sourcing peptidase for bulk manufacturing, buyers must avoid common pitfalls such as relying solely on price, neglecting activity verification, or overlooking storage requirements. A systematic selection process ensures optimal product performance and cost efficiency. Below is a checklist for professional buyers.
- Common Pitfalls: Purchasing based on price alone without verifying purity or activity; assuming all peptidases are interchangeable; ignoring batch-specific stability data.
- Selection Standards: Require a Certificate of Analysis (COA) for each batch, including HPLC purity, activity assay, and microbial limits. Request stability data under recommended storage conditions.
- Buyer Checklist: Confirm supplier GMP certification, request third-party test reports, evaluate packaging for moisture and light protection, and negotiate minimum order quantities (MOQs) that align with production cycles.
- Logistics: Ensure cold chain shipping for lyophilized powder and refrigerated storage upon arrival to maintain enzyme activity.

Frequently Asked Questions
Q1: What is the recommended storage condition for peptidase to maintain activity?
Lyophilized peptidase should be stored at -20°C in a dry, light-protected environment. Reconstituted solutions must be kept at 2–8°C and used within 7 days to avoid significant activity loss. Avoid repeated freeze-thaw cycles.
Q2: How do I verify peptidase purity and activity upon receipt?
Request the Certificate of Analysis (COA) from your supplier, which includes HPLC purity data and activity assay results. For independent verification, send a sample to a third-party lab for HPLC and casein digestion activity testing.
Q3: Can peptidase be used in oil-based cosmetic formulations?
Peptidase is water-soluble and most stable in aqueous systems at pH 6.5–7.5. For oil-based formulations, it should be encapsulated or incorporated into water-in-oil emulsions to maintain enzymatic activity. Pre-formulation stability testing is recommended.
