Core Molecular Specs & Technical Index
Hydrolyzed collagen peptides powder is a high-purity, enzymatically processed protein derivative sourced from bovine, porcine, or marine raw materials. It is specifically designed for B2B buyers in cosmetic formulation, laboratory research, and bulk raw material distribution. The core value lies in its low molecular weight profile, high solubility, and consistent batch-to-batch purity, enabling seamless integration into serums, creams, and research-grade formulations.
Key technical specifications include:
- Molecular weight distribution: 2,000–5,000 Da average, with >90% below 10,000 Da for optimal skin penetration and solubility.
- Purity level: ≥98% protein content (dry basis), with <0.5% ash and <1% moisture to ensure stability and minimal impurities.
- Solubility: Complete dissolution in cold water (≤25°C) within 2 minutes, forming a clear solution without turbidity or sediment.
- pH range: 5.5–7.0 in 1% aqueous solution, compatible with most cosmetic and lab buffer systems.
- Storage stability: 24-month shelf life when stored in sealed containers at 15–25°C, away from direct sunlight and moisture.
Industry data from the International Peptide Society (2023) indicates that hydrolyzed collagen peptides powder with molecular weight below 3,000 Da achieves 40% higher transdermal absorption in vitro compared to standard 10,000 Da variants, making it the preferred choice for premium cosmetic raw materials.
Manufacturing & Quality Control
The production of hydrolyzed collagen peptides powder involves a multi-stage enzymatic hydrolysis process, followed by rigorous purification and quality assurance protocols. Raw collagen is first sourced from certified, traceable suppliers, then subjected to alkaline pretreatment to remove non-collagenous proteins. Controlled enzymatic hydrolysis using food-grade proteases (e.g., Alcalase, Flavourzyme) at 50–55°C for 4–6 hours yields peptides with targeted molecular weight. The hydrolysate is then filtered through 0.2 µm membranes, spray-dried at inlet temperatures of 180–200°C, and milled to a fine powder (≤100 mesh).
Quality control includes third-party testing for heavy metals (lead, arsenic, mercury, cadmium each <1 ppm), microbial limits (total plate count <1,000 CFU/g, yeast/mold <100 CFU/g), and absence of Salmonella, E. coli, and Staphylococcus aureus. Each batch is verified by HPLC for peptide profile and by Kjeldahl method for protein content. Certifications typically include ISO 9001, GMP, and Halal/Kosher compliance, with optional organic or non-GMO verification upon request.
Certification list:
- ISO 9001:2015 quality management system
- GMP (Good Manufacturing Practice) certification
- Halal and Kosher certificates from recognized authorities
- Non-GMO project verification (optional)
- Heavy metal and microbial analysis reports from SGS or Eurofins
Commercial Application Scenarios
Hydrolyzed collagen peptides powder serves as a versatile raw material across multiple B2B sectors. In cosmetic formulation, it is incorporated into anti-aging serums, moisturizing creams, and hair care products at concentrations of 1–5% (w/w). Its low molecular weight ensures rapid absorption into the epidermis, supporting skin hydration and elasticity without leaving a sticky residue. For lab research, it is used as a standard substrate for collagenase activity assays, cell culture supplements, and biomaterial scaffold development, where consistent peptide size distribution is critical for reproducible results.
In bulk wholesale, buyers typically order 25 kg fiber drums or 500 kg super sacks for industrial blending. Usage cases include:
- Cosmetic manufacturers: Blending with hyaluronic acid and vitamin C for premium serum formulations.
- Research institutions: Using as a positive control in enzymatic hydrolysis studies.
- Nutraceutical companies: Incorporating into powdered drink mixes (though not for medical claims).
- Private label brands: Repackaging into consumer-sized containers with custom labeling.

Bulk Purchase Selection Guide
When sourcing hydrolyzed collagen peptides powder for B2B applications, buyers must avoid common pitfalls such as misrepresented molecular weight, hidden impurities, and inconsistent supply. Always request a Certificate of Analysis (COA) from the supplier, specifying molecular weight distribution, protein content, and heavy metal levels. Verify that the COA is from an independent third-party lab, not the manufacturer’s in-house testing. Additionally, check for allergen declarations (e.g., fish, bovine, porcine) to match your target market requirements.
Selection standards include:
- Request a 1 kg sample for in-house solubility and pH testing before bulk order.
- Confirm packaging integrity: double-layer polyethylene bags inside fiber drums with desiccant.
- Ensure lead time of 7–14 days for standard orders, with rush options available.
- Verify supplier’s export experience and documentation (e.g., MSDS, phytosanitary certificate).
Buyer checklist:
- Molecular weight specification (target 2,000–5,000 Da)
- Third-party heavy metal and microbial report
- Certification copies (ISO, GMP, Halal/Kosher)
- Sample evaluation for solubility and clarity
- Minimum order quantity (MOQ) and pricing tiers

Frequently Asked Questions
Q1: What is the typical molecular weight range for hydrolyzed collagen peptides powder used in cosmetics?
The standard molecular weight range is 2,000–5,000 Da, with over 90% of peptides below 10,000 Da. This ensures optimal solubility in cold water and enhanced skin penetration for cosmetic formulations.
Q2: How do I verify the purity of hydrolyzed collagen peptides powder before bulk purchase?
Request a third-party Certificate of Analysis (COA) from an accredited lab like SGS or Eurofins. Key parameters include protein content (≥98% dry basis), ash (<0.5%), moisture (<1%), and heavy metal levels (each <1 ppm). Always test a 1 kg sample in your own formulation conditions.
Q3: Can hydrolyzed collagen peptides powder be used in both water-based and oil-based formulations?
Yes, due to its amphiphilic nature, it dissolves readily in water and can be emulsified into oil-in-water systems. For oil-based formulations, pre-disperse in a small amount of water or glycerin before blending to ensure uniform distribution.
