Hydrolyzed Keratin Peptide Powder for Beauty Formulations
Feather-derived hydrolyzed keratin peptide for B2B ingredient evaluation, with ≥90% protein specification and average molecular weight below 2,000 Da. Review batch analytical data, source qualification and technical documentation before use in the intended finished-product market.
Feather Source Is Verified; Species & Market Suitability Require Separate Documents
The certificate identifies the raw material only as “Feathers.” It does not state chicken, duck or another feather species, and it does not establish food-grade, dietary-supplement or cosmetic regulatory status. Request the current species declaration, process documentation, allergen statement and market-specific regulatory package before finished-product use.
Low-Molecular-Weight Feather Keratin Peptide
The analytical certificate identifies the material as Hydrolyzed Keratin Peptide with Feathers as the raw material. It controls total protein, average molecular weight, moisture, ash, pH, stacking density, heavy metals and microbiology.
The 92.21% result is a total-protein assay and should not be presented as 92.21% keratin purity. The certificate also does not contain an amino-acid profile, so cysteine, cystine, serine or other amino-acid claims should be supported separately.

What Buyers Should Verify in Hydrolyzed Keratin Powder
Commercial search results consistently emphasize source, protein content, molecular weight, COA/TDS, samples, packaging and regulatory paperwork. Use those criteria to compare suppliers rather than relying on generic hair-repair claims.
Feather Source
The certificate confirms Feathers as the raw material. Request the species declaration and traceability documents before publishing chicken- or duck-specific claims.
Protein & Molecular Weight
Protein is specified at ≥90% and the batch reports 92.21%. Average molecular weight is controlled below 2,000 Da.
Market-Specific Documentation
Request current food-use, supplement, cosmetic, allergen, Halal/Kosher or other documentation needed for the destination market instead of inferring status from the COA.
Keratin Peptide for Beauty-Focused Product Development
These are potential formulation pathways, not verified clinical claims. Regulatory suitability, finished-product dosage and performance must be confirmed for the target market.
Beauty Nutrition Concepts
Evaluate feather-derived keratin peptide as a specialty structural-protein ingredient after confirming food-use and supplement-market suitability.
Powdered Formulations
Review flavor, odor, dispersibility and stability in the actual powder blend before commercial scale-up.
Capsules & Tablets
Assess serving size, powder handling, density and excipient compatibility in the target dosage form.
Beauty Ingredient Blends
Evaluate compatibility with collagen peptides, elastin peptide and other beauty-focused ingredients without transferring unsupported clinical claims.
What to Request from a Hydrolyzed Keratin Supplier
The current SERP is crowded with broad purity, solubility and certification claims. A technical buyer should separate certificate-supported facts from additional supplier declarations.
Confirm protein, molecular weight, pH, moisture, ash, heavy metals and microbiology on the commercial lot.
The certificate only says Feathers. Request chicken, duck or other species identification if source-specific positioning is required.
Request current data before making cysteine, cystine, serine, glutamic-acid or other amino-acid claims.
Although the product name is Hydrolyzed Keratin Peptide, request the current manufacturing flow, TDS and market-specific regulatory documentation for finished-product qualification.
The certificate documents 20 kg per bag and an 18,500 kg batch quantity. Confirm current MOQ, inventory and lead time separately.
Hydrolyzed Keratin Peptide Sourcing Questions
What is the raw material for this Hydrolyzed Keratin Peptide?
The certificate identifies the raw material as Feathers. It does not specify chicken, duck or another feather species.
What is the protein specification?
Protein is specified at ≥90.0%. Batch 20260810 reports 92.21%.
Does 92.21% mean 92.21% pure keratin?
No. The certificate reports 92.21% under the Protein test item. It does not provide a separate quantitative keratin-purity assay.
What is the molecular weight of the keratin peptide?
The specification is average molecular weight <2,000 Da, and the batch is reported as passing that specification.
Is the feather source chicken or duck?
The certificate does not identify the species. Request a current source-species declaration before using chicken- or duck-derived language.
Does the COA provide an amino-acid profile?
No. Individual amino acids such as cysteine, cystine, serine or glutamic acid are not quantified on the certificate.
Is this product approved for dietary supplements or food use?
The analytical certificate does not establish regulatory suitability for a specific finished-product market. Request the current market-specific regulatory and food-use documentation before qualification.
What packaging is documented?
The certificate lists 20 kg per bag. The recorded batch quantity is 18,500 kg. Current MOQ and inventory should be confirmed separately.
Can I request technical documents and an evaluation sample?
Yes. Contact ATNUTRA with your intended application, destination market, documentation requirements and expected commercial volume.
