Product identity
A feather-derived protein hydrolysate for ingestible beauty and pet formulations
The reference certificate names the product Hydrolyzed Keratin Peptide and lists Feathers as the raw material. It reports protein, physical properties, a molecular-weight specification and safety tests, but does not identify the feather species, hydrolysis method, keratin subtype, amino-acid profile or peptide distribution.
Technical interpretation
Separate measured batch facts from unverified absorption and beauty claims
The COA supports a high protein result and a molecular-weight specification. It does not prove that all protein is a specific keratin subtype, that every peptide is below 2,000 Da, or that the ingredient is delivered directly to hair follicles or nail tissue.
Total protein result under GB5009.5. Request keratin identity and amino-acid data for more specific composition claims.
This is the printed specification; the batch result is Pass. A numeric average and distribution are not shown.
Measured in a 6.67% aqueous solution. It does not establish beverage clarity, solubility or gummy stability.

Formulation applications
Evaluate the grade in the actual supplement or pet-product format
The reference COA provides protein, pH, density and safety data. It does not provide flowability, compression, solubility, taste-masking or stability results, so those properties require bench and pilot testing.

In-House QA Laboratory
Link release statements to protein, moisture, ash, pH, molecular-weight specification, metals and microbiological results.
Feather Source Review
Confirm feather species, supplier qualification, country of origin, traceability and any animal-source suitability documents.
Process & Peptide Review
Confirm the hydrolysis method, processing aids, molecular-weight distribution and amino-acid profile for the commercial specification.
Batch COA Release
Release against the approved composition, physical, heavy-metal and microbiological specification.

B2B frequently asked questions
Questions from keratin-peptide buyers, R&D and quality teams
The answers distinguish facts printed on the COA from claims requiring separate evidence.
The reference COA lists the raw material only as Feathers. It does not state chicken, duck or mixed poultry. Request a species and source declaration before approval.
No. The COA reports Protein under GB5009.5. It does not print an exact keratin percentage, subtype or amino-acid composition.
The printed item is Average Molecular Weight with a specification of <2,000 Da and a result of Pass. The certificate does not provide a numeric average or distribution chart.
Solubility, clarity, sedimentation, taste masking and process stability are not reported on the COA. Test the ingredient under the intended pH, temperature, mixing and storage conditions.
It is animal-derived and not vegan. Halal or Kosher suitability depends on the feather source, enzymes, processing aids, facility and current certificate scope.
The reference COA lists 20 kg per bag and an 18,500 kg batch quantity. Confirm MOQ, sample size, current stock, lead time and freight terms in the current quotation.
