Hydrolyzed Feather Keratin Powder is a premium, high-protein natural material extracted from poultry feathers via advanced controlled hydrolysis. Feathers are naturally rich in beta-keratin and cross-linked disulfide bonds. Through our specialized bio-conversion process, we transform this robust structural protein into a highly digestible, soluble, and bio-active powder. It boasts high homology, excellent moisturizing properties, and high nutritional value, making it an ideal raw material for cosmetics, animal husbandry, and advanced biomaterials.

Formulation Advantages
1. High Purity & Nutritional Value
Through precise biological hydrolysis, the powder achieves a protein content exceeding 82%. It is incredibly rich in essential amino acids (especially serine, proline, and cystine), making it a highly valuable, digestible protein source for animal nutrition.
2. Biological Affinity & Moisturizing Ability
Rich in hydrophobic amino acids, feather keratin exhibits high biological homology with human hair and skin. It forms a protective micro-film, enhancing moisture retention and barrier function in cosmetic formulations.
3. Efficient Degradation & Sustainability
Converting poultry feathers into hydrolyzed keratin is a highly sustainable, eco-friendly process. Utilizing targeted keratinase enzymes, we achieve complete hydrolysis within 24 hours, transforming agricultural by-products into premium bioactive materials while eliminating environmental waste.
4. Proven Biosafety
In vitro studies demonstrate that our hydrolyzed keratin exhibits excellent biocompatibility and safety profiles, presenting no cytotoxicity, which perfectly supports its application in biomedical and cosmetic developments.
Industrial Application Areas
1. Animal Nutrition & Feed Additives
As an excellent protein supplement, the high concentration of amino acids (specifically lysine and cystine) significantly enhances the nutritional profile of animal feed, promoting healthy growth and development in livestock and aquaculture.

2. Cosmetic & Personal Care
Widely utilized in hair care and skincare products. The peptides penetrate damaged hair shafts to repair missing cuticle scales, enhance structural toughness, and form a protective hydrogen-bonded film that improves smoothness and hydration.
02
3. Agricultural Fertilizers & Bio-stimulants
Processed feather hydrolysates serve as highly effective organic nitrogen sources and plant growth promoters, improving soil microbiome health and overall crop yield.
03
4. Eco-Friendly Biomaterials
Keratin hydrolysates are being researched and utilized to manufacture low-cost, biodegradable thermoplastic composite materials, offering sustainable alternatives in automotive interiors and textile modifications.

Standardized Production Process
1. Collection & Preprocessing:
Discarded poultry feathers are collected and undergo rigorous cleaning, decontamination, and defatting to remove impurities. The clean feathers are then finely ground into powder.
2. Controlled Hydrolysis (Alkaline/Enzymatic):
The feather powder is mixed with a controlled alkaline solution (or specific keratinase enzymes) and heated to 60°C. This process efficiently breaks down the tough disulfide bonds, dissolving the resilient keratin structure.
3. Precipitation & Filtration:
The pH of the hydrolyzed solution is adjusted to precisely precipitate the keratin proteins. The mixture is then centrifuged, separating the high-value solid particles from the supernatant.
4. Purification:
The precipitated keratin is washed multiple times with deionized water until a neutral pH is achieved, ensuring the removal of any residual salts or reagents.
5. Drying & QA Testing:
The purified solid is dried at controlled temperatures to obtain the final Hydrolyzed Keratin Powder. Each batch is verified for protein content, moisture, and amino acid profiles before packaging.

B2B Frequently Asked Questions
Q1: What is the difference between feather keratin and wool keratin?
A: While both are rich in cystine, feather keratin is highly valued in the animal nutrition industry for its exceptional overall protein content (≥82%) and specific amino acid profile, making it a highly cost-effective and digestible feed additive compared to wool.
Q2: Can I get samples for formulation or feed testing?
A: Yes, we fully support R&D and trial efforts. We can provide free samples for your lab or farm testing; clients only need to cover the international courier freight.
Q3: Is the hydrolysis process safe and eco-friendly?
A: Yes. We utilize controlled alkaline and enzymatic hydrolysis to efficiently break down the tough disulfide bonds in feathers, converting agricultural by-products into high-value, bio-available proteins without creating environmental pollution.
Q4: How do you guarantee the quality and safety of the raw materials?
A: We strictly source poultry feathers from CIQ-inspected and approved facilities. Our stringent purification and washing processes ensure the final powder is free from harmful residues and pathogens.
