Hydrolyzed Keratin Production for Hair-Care Ingredient Makers
Turn feather, wool and hair keratin into soluble peptide fractions for hair-care, nail-care and skin-care ingredient lines, with an enzyme step you can specify, trial and reorder.
Hair waste from salons, textile mills, and wool processing plants contains durable keratin proteins that resist breakdown by conventional proteases. For a plain explanation of how the enzyme attacks this protein, see this Japanese-language guide to how keratinase breaks down keratin. For ingredient makers, the same durability means coarse keratin feedstock is slow to convert, hard to filter and difficult to standardize from batch to batch.
Keratinase gives hydrolysate producers a controlled enzyme step. It hydrolyzes disulfide-rich keratin from feather, wool and hair into smaller, soluble peptides and amino acids, so the output can be refined into hair-care and personal-care ingredient lines. Our grades run at pH 7.0–10.0 and 50–70 °C and fit slurry tanks, jacketed reactors or continuous systems; the dose is set by feedstock type, particle size and the hydrolysis level you need (see the specification table below).

Hair Care Keratin Hydrolysate Production
Manufacturers producing hair care keratin ingredients need a controllable hydrolysis step that converts coarse keratin feedstocks into soluble peptides. Keratinase supports this by degrading disulfide-rich structures in feather, wool, and hair-derived material under alkaline conditions. Typical runs use pH 7.0–10.0, 50–70 °C, and 0.1–1.0% dosage on dry substrate, depending on feedstock and desired molecular weight profile.
Keratin Hair Treatment Ingredient Development
For buyers sourcing inputs for keratin hair treatment lines, the goal is functional protein hydrolysates for masks, conditioners, and salon-grade treatments. Keratinase converts raw keratin into smaller peptides with better solubility and processability, simplifying filtration and standardization while ensuring consistent ingredient supply.
Hair Keratin Processing Optimization
Processors of hair keratin intermediates often face slow breakdown, high viscosity, and uneven conversion. Keratinase reduces residence time and improves batch consistency when paired with controlled agitation and temperature. A starting point is 0.2–0.5% enzyme on substrate, then optimizing for viscosity reduction, soluble nitrogen, and yield.
Circular Sourcing for Cosmetic Protein Inputs
Many ingredient buyers face pressure to adopt responsible sourcing. Keratinase enables waste-to-value conversion of feather, hair, and wool residues into usable protein fractions for hair care supply chains. This supports circular procurement goals while reducing disposal burden.

Frequently Asked Questions
How does keratinase support keratin hair treatment ingredient manufacturing?
Keratinase breaks down highly resistant keratin structures into smaller peptides suitable for ingredient manufacturing. For hair keratin treatment supply chains, this means improved conversion of feather, wool, or hair-derived feedstocks into hydrolysates with enhanced solubility and processability. Industrial use involves operating at pH 7.0–10.0, 50–70 °C, followed by refining the hydrolysate for cosmetic applications.
What is a practical dosage for pilot-scale trials?
A typical starting range is 0.1–1.0% enzyme on dry substrate, with many trials beginning at 0.2–0.5% to establish baseline conversion. The optimal dosage depends on keratin source, particle size, mixing, and target hydrolysis. More recalcitrant materials like dense hair waste may require higher doses or longer residence times, measured by soluble nitrogen, viscosity, and recovery yield.
Is keratinase suitable for hair care keratin hydrolysate production?
Yes. Keratinase is widely used to convert keratin-rich inputs into functional hydrolysates for hair care applications. It improves the release of soluble peptide fractions while offering a controlled process compared to harsh chemical hydrolysis, delivering consistent ingredient quality and recoverable value from waste streams.
What process conditions are recommended?
Recommended conditions are pH 7.0–10.0 and 50–70 °C, adaptable to feedstock stability and reactor design. For hair treatment ingredient lines, balancing temperature, agitation, and enzyme dosage can manage viscosity and ensure reproducibility. Small-scale validation is always advised before full-scale implementation.
Can keratinase help with sustainable sourcing goals?
Yes. Keratinase enables conversion of keratin-rich by-products into valuable hydrolysates, reducing waste and supporting circular economy objectives. This helps lower disposal costs and improve traceability, providing both operational and sustainability benefits to ingredient manufacturers.
What should a quote request for a hydrolysate line include?
The product (activity grade), the quantity per order or per year, the destination country, and your feedstock (feather, wool or hair) with the target output. Packs are 1 kg, 5 kg and 25 kg with MOQ 1 kg; price is quoted per order.
