Keratin is an extremely durable, fibrous structural protein found in hair, nails, and the outer layers of skin. Because of its highly cross-linked structure containing disulfide bonds, native keratin is insoluble in water and exhibits low bioavailability. At Hangzhou Fderla Biology Co., Ltd., we employ advanced enzymatic hydrolysis technology to overcome this limitation. By breaking down the large, complex polypeptide chains of keratin into lower-molecular-weight bioactive peptides, we render the protein water-soluble, highly bioavailable, and deeply penetrative for target cells.
| Property | Cosmetic Grade (Powder/Liquid) | Food Grade (CAS 69430-36-0) |
|---|---|---|
| Protein Content | ≥ 98.0% | ≥ 90.0% |
| Average Molecular Weight | 1,000 - 3,000 Da (Customizable) | 500 - 1,500 Da (High Bioavailability) |
| Solubility | 100% Water Soluble (Clear Solution) | 100% Water Soluble |
| Cysteine Content | High (Ensures disulfide bond rebuilding) | Optimized for keratin synthesis |
| Heavy Metals (Pb, As, Hg) | ≤ 10 ppm total | ≤ 2 ppm total (Strict Food Standard) |
Our enzymatic pathways are meticulously calibrated. By avoiding harsh acid or alkali treatments, we protect the essential amino acid profile, particularly the high levels of Cystine. This ensures that when our cosmetic-grade hydrolyzed keratin is formulated into hair treatments, it effectively binds to the damaged hair shaft, cross-linking with natural hair proteins to smooth the cuticle and restore structural integrity.
For procurement officers in the personal care, nutraceutical, and clinical cosmetics sectors, securing a stable supply of Hydrolyzed Keratin involves navigating complex technical, safety, and logistical criteria. Fderla Biology bridges the gap between raw bio-materials and ready-to-formulate products through our macro-industrial solutions:
We customize average molecular weights to match your application. 1000 Da for deep hair cortex penetration; 3000 Da for protective film-forming properties on the skin.
Full compliance with FDA, EU REACH, and China CSAR regulations. Our food-grade keratin peptide CAS 69430-36-0 features detailed toxicological and heavy metal documentation.
Go beyond raw materials. We supply finished formulations, including professional hair straightening treatments (12% pure Brazilian keratin) and moisturizing hair mask kits.
As a verified bulk manufacturer, Hangzhou Fderla Biology Co., Ltd. maintains strong logistics partnerships to service key global markets in North America, Europe, Southeast Asia, and Latin America. We support multiple packaging configurations, from 1kg sample foils to 25kg fiber drums, with full temperature-controlled warehousing options for liquid formats.
The global keratin market is undergoing a major evolution, driven by the clean beauty movement and a rising consumer demand for functional nutricosmetics (beauty-from-within). Fderla Biology is positioned at the forefront of these transitions through our active R&D investments:
Technical Outlook for 2026/2027: Our research team is currently validating next-generation recombinant keratin peptides. These non-animal, bio-fermented proteins will match the exact amino acid sequence of human hair keratin, offering a 100% vegan solution with superior structural efficacy.
Technical, commercial, and regulatory answers for chemical buyers and cosmetic formulators.
Cosmetic-grade hydrolyzed keratin (often up to 98% purity) is optimized for molecular weights that allow hair binding and cuticle sealing. Food-grade hydrolyzed keratin (CAS 69430-36-0) must meet stringent microbiological, heavy metal, and allergen safety tests suitable for oral ingestion, targeting hair and nail growth supplements.
Yes. Using advanced bio-enzymatic cleavage controls at our Hangzhou factory, we can tailor the average molecular weight. For formulations requiring deep hair cortex reconstruction, we target <1000 Daltons. For protective skin barrier products, we target >2000 Daltons.
Absolutely. Our hydrolyzed keratin protein complies with US FDA guidelines, EU REACH registry requirements, and China's Cosmetic Supervision and Administration Regulation (CSAR). We provide full COA, MSDS, and heavy metal test reports for every batch.
Our standard MOQ for powder products is 25kg (shipped in standard fiber drums). For liquid bulk formulations, MOQ varies depending on custom preservation requests. Sample quantities (100g - 1kg) are available for R&D evaluation.
Yes, Fderla Biology provides comprehensive contract manufacturing. We can formulate, package, and label finished products, including professional 12% Brazilian keratin smoothing treatments, repair masks, and botanical shampoo combinations.
