Explore our leading selection of hydrolyzed proteins, specialized peptides, and high-bioavailability formulations engineered for cosmetics, nutraceuticals, and premium pet care.
Within the highly specialized landscape of bioactive protein manufacturing, Hydrolyzed Keratin Peptides stand out due to their intricate structural homology with human hair, skin, and nails. Unlike standard proteins, which have high molecular weight barriers that prevent penetration, the advanced enzymatic hydrolysis protocol engineered at Hangzhou Fderla Biology Co., Ltd. precisely fractures dense polypeptide chains into micro-peptides with molecular weights strictly below 1000–3000 Daltons.
"The true efficacy of keratin peptides is not determined solely by protein content, but by the distribution of peptide chains and the integrity of their cysteine molecules, which are essential for disulfide bond restoration."
By using target-specific, plant-derived, and food-grade proteolytic enzymes, we preserve crucial sulfur-containing amino acids (principally L-Cysteine). This enables deep penetration into the hair cortex, forming strong covalent bonds with damaged cell structures and restoring tensile strength by up to 27% compared to untreated controls.
Purchasing raw materials for global cosmetic and supplement brands requires balancing safety, efficacy, and supply chain transparency. Many raw materials struggle with batches that contain high molecular weights, excessive ash levels, or heavy metal contamination. For sourcing managers, verifying the purity of Hydrolyzed Keratin Peptides is critical to preventing downstream production issues.
When selecting a raw material exporter, specifications must align with strict international regulations. Below is the standard technical specification matrix used by top tier formulation laboratories globally:
| Analytical Parameter | Standard Specification Range | Testing Methodology (USP/EP) |
|---|---|---|
| Assay (Protein Content on Dry Basis) | ≥ 90.0% to 95.0% | Kjeldahl Method / Dumas Combustion |
| Average Molecular Weight (Mw) | 1,000 to 3,000 Daltons (Customizable) | High-Performance Liquid Chromatography (HPLC) |
| Loss on Drying | ≤ 5.0% | Vacuum Oven Drying at 105°C |
| Total Ash Content | ≤ 3.0% | Muffle Furnace Ashing at 550°C |
| Heavy Metals (Pb, As, Cd, Hg) | ≤ 10 ppm total (Pb ≤ 2.0 ppm, As ≤ 1.0 ppm) | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) |
| Microbiological Quality | Total Plate Count ≤ 1000 cfu/g; Pathogens Negative | Plate Count Agar / USP <61/62> |
China has established itself as a leading global hub for industrial biotechnology. At Hangzhou Fderla Biology Co., Ltd., we utilize advanced raw material sourcing networks, high-capacity enzymatic reactors, and spray-drying technologies to achieve cost-efficiency without compromising quality. This allows us to offer competitively priced, high-grade protein powders compared to traditional European suppliers.
Our facility in Hangzhou integrates high-throughput production lines with automated control loops. By monitoring pH, temperature, enzyme-to-substrate ratios, and reaction times in real-time, we ensure consistent peptide chain lengths across every batch. Our high-efficiency production allows us to meet strict B2B delivery schedules, offering reliable supply during global market fluctuations.
Entering international cosmetics and food markets requires meeting complex regulatory guidelines. Each region has specific registration and safety assessment protocols:
To support global supply chains, we provide comprehensive documentation for every batch, including Certificate of Analysis (COA), Safety Data Sheets (SDS/MSDS), Allergen Declarations, Non-GMO Statements, and BSE/TSE-Free Certifications. This complete documentation package helps expedite customs clearance and simplifies our clients' formulation registration processes.

By combining scientific research, production excellence, and global service capability, Fderla Biology has become a trusted partner in the hydrolyzed protein and bioactive peptide industry, delivering reliable and high-performance ingredient solutions worldwide.
Understanding how hydrolyzed proteins behave in different formulations is essential for successful product development. Below are the key target areas where our peptide ingredients provide performance advantages:
In high-performance shampoos, masks, and hair ampoule treatments, Hydrolyzed Keratin Proteins bond to hair fibers. Because of their cysteine residues, they repair areas damaged by chemical treatments or heat styling. Formulators typically combine these with hydrolyzed collagen or wheat proteins to create a balanced moisture-and-repair system.
In ingestible beauty products, hydrolyzed peptides supply the body with specific amino acids needed for natural keratin synthesis. Their high solubility, mild taste, and stability at low pH values make them suitable for ready-to-drink functional beverages, beauty shots, and tablet formulations.
Hydrolyzed keratin is used in skincare to help maintain skin elasticity and moisture. The peptides form a breathable, protective film on the stratum corneum, helping to reduce transepidermal water loss (TEWL) and leaving skin feeling smooth.
Pet nutrition is increasingly incorporating bioactive peptides to support coat health and joint function. Products containing hydrolyzed proteins, green-lipped mussel, and cartilage extracts help support joint health and nutrient absorption in dogs and cats.
