Core Molecular Specs & Technical Index
Hydrolyzed collagen peptide, known in Spanish-speaking markets as colageno hidrolizado, is a high-purity bioactive protein fraction obtained through controlled enzymatic hydrolysis of native collagen. For B2B buyers—including cosmetic formulation chemists, nutraceutical manufacturers, and laboratory research teams—the core value lies in its consistent molecular weight distribution, exceptional solubility, and batch-to-batch reproducibility. This guide provides a comprehensive technical and commercial reference for sourcing premium hydrolyzed collagen peptide wholesale.
Core Molecular Specs & Technical Index
Professional procurement requires precise understanding of the technical parameters that define colageno hidrolizado quality. The following specifications are critical for evaluating supplier consistency and product performance.
- Molecular Weight Distribution: Optimal range is 500–3000 Da, with a minimum 90% fraction below 3000 Da. This ensures maximum solubility and bioavailability in both aqueous and cosmetic formulations.
- Purity & Protein Content: Minimum 95% protein content (dry basis) with less than 1% ash and less than 0.5% fat. High purity guarantees minimal interference in sensitive formulations.
- Solubility Profile: Complete solubility in cold water (10°C) at concentrations up to 20% w/v without gelation. This property is essential for clear liquid formulations and injectable-grade research products.
- pH Stability: Stable in pH range 3.0–8.0, with optimal activity at pH 5.5–7.0. This allows integration into diverse cosmetic and laboratory buffer systems.
- Storage & Shelf Life: 24 months in sealed, moisture-proof packaging at 15–25°C. Avoid direct sunlight and temperatures above 40°C to prevent peptide degradation.
Industry data from the International Peptide Society (2024) indicates that hydrolyzed collagen peptide with molecular weight below 2000 Da demonstrates 98% solubility in water at 25°C, compared to only 45% for non-hydrolyzed collagen. This solubility advantage is the primary driver for its adoption in premium cosmetic and nutraceutical applications.
Manufacturing & Quality Control
The production of high-grade colageno hidrolizado follows a tightly controlled enzymatic hydrolysis process, ensuring consistent peptide chain length and functional properties.
Raw material selection begins with bovine or porcine hides, or marine fish skin, sourced from certified, traceable suppliers. The material undergoes rigorous cleaning, degreasing, and demineralization before enzymatic treatment. Food-grade proteases (e.g., Alcalase, Neutrase) are applied under controlled temperature (50–60°C) and pH (6.5–8.0) for 4–8 hours, achieving the target degree of hydrolysis (DH) of 15–25%.
Post-hydrolysis, the solution is filtered through 0.2-micron membranes to remove insoluble residues, then passed through activated carbon columns for decolorization and deodorization. The purified peptide solution is concentrated via vacuum evaporation and spray-dried to a fine, free-flowing powder with moisture content below 5%.
Third-party testing is mandatory for B2B transactions. Each batch is analyzed for heavy metals (lead, arsenic, cadmium, mercury), microbiological purity (total plate count, yeast, mold, Salmonella, E. coli), and peptide molecular weight distribution via HPLC. Certificates of Analysis (COA) are provided with every shipment.
Certifications required for international trade include:
- ISO 9001:2015 (Quality Management System)
- FSSC 22000 or ISO 22000 (Food Safety)
- Halal and Kosher certification (for specific markets)
- Non-GMO verification
- EU Novel Food compliance (for European import)
Commercial Application Scenarios
Hydrolyzed collagen peptide wholesale serves three primary commercial channels, each with distinct technical requirements.
Cosmetic Formulation: In anti-aging serums, moisturizers, and hair care products, colageno hidrolizado functions as a film-forming agent and humectant. It improves skin elasticity and reduces transepidermal water loss. Formulators require a peptide with low odor, neutral taste, and complete solubility in water-based systems. Typical usage rates range from 1% to 5% in leave-on products and up to 10% in rinse-off masks.
Laboratory Research: For cell culture, tissue engineering, and biochemical studies, researchers need ultra-pure hydrolyzed collagen peptide with endotoxin levels below 0.5 EU/mg. This grade is often supplied in sterile, lyophilized form with a defined molecular weight cut-off (e.g., 1000 Da or 3000 Da). Bulk orders for academic institutions and biotech firms require batch consistency and detailed analytical data.
Bulk Wholesale Usage: Nutraceutical manufacturers blend hydrolyzed collagen peptide into powdered drinks, capsules, and functional foods. The key requirements are high solubility in cold beverages, neutral taste, and rapid dissolution without clumping. Wholesale quantities typically start at 500 kg per order, with customized packaging options (25 kg drums, 500 kg super sacks, or 1-ton bulk bags).

Bulk Purchase Selection Guide
Procuring colageno hidrolizado wholesale requires careful evaluation to avoid common pitfalls that compromise product quality and supply chain reliability.
Common Pitfalls: The most frequent issue is receiving low-molecular-weight peptide that is actually a mixture of gelatin and free amino acids, not true hydrolyzed collagen. This results in poor solubility and reduced functional performance. Another pitfall is inconsistent batch quality—some suppliers change raw material sources without notice, altering peptide profile and causing formulation failures.
Selection Standards: Always request a Certificate of Analysis (COA) for each batch, including molecular weight distribution (HPLC chromatogram), protein content (Kjeldahl method), and heavy metal analysis (ICP-MS). Verify that the supplier performs third-party testing at an accredited laboratory (e.g., SGS, Eurofins, or Intertek). Ask for a sample (minimum 1 kg) and test it in your own formulation before committing to a large order.
Buyer Checklist:
- Confirm molecular weight specification in writing.
- Request microbiological and heavy metal certificates.
- Verify certifications (ISO, FSSC, Halal, Kosher).
- Check packaging integrity and labeling accuracy.
- Establish a quality agreement for ongoing supply.
- Negotiate lead time and minimum order quantity (MOQ).
- Ensure supplier has a documented traceability system.

Frequently Asked Questions
Q1: What is the difference between hydrolyzed collagen peptide and gelatin?
Hydrolyzed collagen peptide is produced by enzymatic hydrolysis that breaks collagen into smaller peptides (500–3000 Da), making it cold-water soluble and highly bioavailable. Gelatin is partially hydrolyzed collagen with larger molecular weight (5000–10000 Da) that forms gels in cold water and requires heat for dissolution. For cosmetic and nutraceutical applications, hydrolyzed collagen peptide is preferred due to its superior solubility and functional properties.
Q2: How do I verify the molecular weight distribution of a batch?
Request a High-Performance Liquid Chromatography (HPLC) chromatogram from the supplier. The chromatogram should show a single broad peak with a retention time corresponding to 500–3000 Da. Compare the area under the curve to a molecular weight standard. Reputable suppliers provide this data on every Certificate of Analysis. You can also request third-party verification from an accredited laboratory.
Q3: What is the minimum order quantity (MOQ) for wholesale colageno hidrolizado?
Standard MOQ for premium hydrolyzed collagen peptide is 500 kg per product specification. For first-time buyers, some suppliers offer trial orders of 25 kg or 50 kg at a slightly higher per-kg price. Custom packaging (e.g., 1 kg vacuum-sealed bags for laboratory use) may have a higher MOQ. Always confirm MOQ and lead time (typically 15–30 days) before placing an order.
