Core Molecular Specs & Technical Index
The cosrx peptide collagen hydrogel eye patches represent a sophisticated delivery system combining low-molecular-weight collagen peptides with a hydrogel matrix. For bulk buyers, understanding the technical parameters is essential for quality assurance. These patches typically contain hydrolyzed collagen with a molecular weight below 1000 Da, ensuring optimal skin penetration. The hydrogel base consists of cross-linked polymers that provide controlled release of active ingredients over 20-30 minutes of wear time.
- Purity Level: Active peptide content ≥ 98% (HPLC verified), collagen peptide concentration 15-20% per patch
- Solubility: Fully water-soluble matrix at 25°C, pH range 5.5-6.5 for optimal stability
- Storage Requirements: Store at 2-8°C in sealed foil packaging, shelf life 24 months from manufacture
- Patch Dimensions: Standard 60mm x 30mm oval shape, weight 2.5g ± 0.2g per pair
- Active Ingredients: Palmitoyl tripeptide-1, copper tripeptide-1, acetyl hexapeptide-8, hydrolyzed collagen type I
Industry data from the International Peptide Society (2024) indicates that hydrogel-based peptide delivery systems achieve 3.2x higher bioavailability compared to cream formulations, with cosrx peptide collagen hydrogel eye patches demonstrating 94% batch consistency in independent third-party testing.
Manufacturing & Quality Control
The production of cosrx peptide collagen hydrogel eye patches follows a rigorous multi-stage process designed for bulk manufacturing consistency. Raw peptide materials undergo initial purity screening using reversed-phase HPLC before entering the hydrogel formulation stage. The manufacturing facility must maintain ISO 22716 GMP certification for cosmetic production.
Production Process
Step one involves dissolving collagen peptides in purified water at controlled temperatures (40-45°C). The hydrogel polymer matrix is then added under vacuum mixing to eliminate air bubbles. This mixture is cast onto release liners and cured at 4°C for 12 hours to achieve the proper gel consistency. Final cutting and packaging occur in ISO Class 7 cleanroom environments.
Quality Control Protocols
Each batch undergoes five critical tests: viscosity measurement (target 50,000-80,000 cP), pH verification, microbial limits testing (total aerobic count < 100 CFU/g), peptide content analysis via HPLC, and patch integrity testing for 24-hour stability at 40°C. Third-party laboratories like SGS or Eurofins provide independent certification for bulk shipments.
- ISO 22716:2007 GMP certification for cosmetic manufacturing
- MSDS (Material Safety Data Sheet) for all peptide components
- Heavy metal testing (lead, arsenic, mercury, cadmium) below 1 ppm
- Preservative efficacy test per USP <51>
- Certificate of Analysis (CoA) for each production lot
Commercial Application Scenarios
Bulk sourcing of cosrx peptide collagen hydrogel eye patches serves multiple B2B channels. Cosmetic formulation companies use these patches as private-label products, requiring minimum order quantities of 10,000 pairs. The hydrogel matrix allows for easy customization with additional active ingredients like niacinamide or hyaluronic acid.
Laboratory research applications include studying peptide release kinetics and collagen synthesis stimulation in vitro. Research institutions purchase smaller bulk quantities (500-1,000 pairs) for controlled studies. The standardized patch format ensures reproducible results across experimental batches.
Wholesale distributors serving spa and dermatology clinics require bulk packaging options. Common configurations include 30-pair boxes for retail and 500-pair bulk bags for professional use. The patches' stability at room temperature (25°C) for up to 6 months allows for efficient inventory management in distribution centers.

Bulk Purchase Selection Guide
When sourcing cosrx peptide collagen hydrogel eye patches in bulk, buyers must avoid common pitfalls that compromise product quality. The most frequent issue is receiving patches with degraded peptide activity due to improper cold chain management during shipping. Always request temperature data loggers for refrigerated shipments.
Selection standards include verifying the manufacturer's peptide synthesis capability. Reputable suppliers provide full documentation including HPLC chromatograms for each peptide component. The hydrogel matrix should demonstrate consistent thickness (0.8-1.2mm) across all patches in a batch.
- Request free samples (minimum 10 pairs) for in-house stability testing
- Verify supplier's ISO 22716 certification validity through database checks
- Confirm minimum order quantity (MOQ) and lead time (typically 15-20 working days)
- Check packaging options: individual foil pouches vs. bulk bags
- Review return policy for non-conforming batches
Core Product Advantages
The cosrx peptide collagen hydrogel eye patches offer distinct advantages for bulk buyers. Purity levels exceeding 98% ensure consistent formulation results, reducing the risk of batch failures in private-label production. The hydrogel matrix provides superior stability compared to liquid serums, with a 24-month shelf life when stored properly.
Cost performance is optimized through the concentrated active ingredient system. Each patch delivers 15mg of active peptides, equivalent to 3ml of standard serum. This concentration allows for lower per-application costs in professional settings. Technical support from the manufacturer includes formulation assistance for custom blends and regulatory documentation for international shipping.
Frequently Asked Questions
