Hydrolyzed keratin effectively penetrates the hair shaft, replenishing proteins and lipids lost due to chemical treatments, heat styling, or environmental stressors. Furthermore, pure hydrolyzed keratin exhibits a natural affinity for damaged hair; compromised cuticles expose hydrophilic protein structures, thereby facilitating easier binding with water-soluble keratin peptides to form a protective protein film. This film not only fills gaps in the hair cuticle-reducing breakage and split ends-but also significantly enhances the hair's tensile strength and resilience. The physical barrier it creates on the hair's surface acts as a shield against daily damage caused by UV radiation, pollution, and heat styling tools, delivering a multifaceted combination of repair, nourishment, and protection.
Where does hydrolyzed keratin come from?
Our hydrolyzed keratin from china raw material is derived from feathers-a β-keratin matrix structurally highly similar to human hair. Through a precisely controlled enzymatic hydrolysis process, we break down natural high-molecular-weight keratin into low-molecular-weight, water-soluble peptide fragments, yielding premium-quality hydrolyzed keratin powder. As a specialized manufacturer, KINTAIBIO® offers comprehensive technical support-ranging from raw material selection and customized enzymatic hydrolysis parameters to formulation application recommendations.

How to make Hydrolyzed Keratin Powder?
Raw Material Inspection and Pre-treatment
Place the animal feathers into a reaction vessel. Add purified water at a mass ratio of raw material to water of 1:2. Raise the temperature to 90–100°C and maintain this temperature for 8–12 hours to remove grease, bloodstains, and impurities. After treatment, drain the wastewater and rinse with clean water until thoroughly clean. The washed raw material is then hot-air dried at 90–100°C until its moisture content falls below 2%. The dried raw material is pulverized using a high-efficiency grinder and sieved to obtain a uniform granular powder with a mesh size of 100–120.
Alkaline Treatment (Preliminary Hydrolysis)
Add the aforementioned powder to a reaction tank at a mass ratio of powder to water of 1:1.0–1.5. While stirring, add a food-grade alkali (any one of sodium hydroxide, potassium hydroxide, calcium hydroxide, or sodium carbonate) to adjust the solution pH to 8.5–9.5. Heat the mixture to boiling and maintain a gentle boil for 8–12 hours to facilitate the preliminary degradation of the keratin, thereby obtaining an alkaline-treated solution.
Compound Enzymatic Hydrolysis
Cool the alkaline-treated solution down to 55–60°C. Add the following enzymes sequentially: Protamex protease (at an addition rate of 0.8%–1.2% of the alkaline-treated solution's mass) and Flavourzyme flavor protease (at an addition rate of 0.5% of the alkaline-treated solution's mass). Stir the mixture at a constant temperature of 55–60°C for 4 hours to carry out the enzymatic hydrolysis. Raise the solution temperature to 90°C and hold it for 30 minutes to ensure the complete inactivation of the enzymes. Centrifuge the solution or filter it using a plate-and-frame filter press to collect the clear filtrate, discarding the insoluble residues.
Vacuum Concentration
Transfer the clear liquid into a vacuum concentration unit. Control the vacuum level and temperature (typically ≤70°C) to concentrate the solution until its solid content (concentration) reaches ≥40%.
Spray Drying and Packaging
Pump the concentrated liquid into a spray drying tower using a high-pressure pump. Control the inlet air temperature within an appropriate range (typically 180–220°C) and the outlet air temperature at 80–100°C to obtain a dry powder product. The final product's moisture content shall be ≤8.0%. After drying, the hydrolyzed keratin powder is passed through a 40-mesh vibrating screen to ensure it is free of lumps; it is then hermetically sealed in paper drums lined with food-grade plastic bags, or in aluminum foil bags, and labeled with the batch number, production date, and other relevant details.
Hydrolyzed Keratin Powder benefits
What Does Hydrolyzed Keratin Powder Do For Hair?
In the realm of hair care, daily photo-aging stands as one of the primary mechanisms leading to hair damage and diminished structural integrity; notably, hydrolyzed keratin has demonstrated a remarkable mechanism of action in preventing such damage. Studies indicate that keratin protein hydrolyzed forms a film upon the surface of the hair cuticles while partially penetrating into the cortex, thereby establishing a physical barrier to shield against ultraviolet (UV) radiation damage. Crucially, exposure to UV light triggers the further degradation of hydrolyzed keratin into smaller polypeptides and amino acids, facilitating their deeper penetration into the hair shaft to reinforce chemical bonds and enhance tensile strength.
Experimental data corroborates these findings: hair pre-treated with hydrolyzed keratin retains its original tensile strength following UV exposure, whereas the strength of untreated hair strands declines by 14.32%. This signifies that hydrolyzed keratin powder not only provides physical UV protection through its film-forming properties but also leverages the process of photodegradation to transform into highly penetrative, active small molecules, thereby delivering deep-repair effects that reinforce the hair's mechanical properties from the inside out.
Hydrolyzed Keratin Powder For Nails
In the realm of nail care, a clinical study has confirmed that the oral intake of hydrolyzed keratin significantly improves nail health. In this trial, following daily supplementation with a specific dosage of hydrolyzed keratin protein, subjects demonstrated significantly superior nail hardness and luster compared to the placebo group.
This hydrolyzed keratin is rich in free L-amino acids; its mechanism of action extends beyond traditional protein nutrition, functioning as an "amino-bioactive agent" to systemically strengthen nails and other skin appendages. As a professional manufacturer of hydrolyzed keratin powder, we are dedicated to providing high-quality raw materials, offering robust scientific evidence to support your product formulations.
Hydrolyzed Keratin Powder for skin
A systematic functional study indicates that commercially available hydrolyzed keratin powder products of varying molecular weights exhibit significant differences in their surface activity, emulsifying capabilities, and thickening properties. Specifically, hydrolyzed keratin with an average molecular weight exceeding 3,000 Da and a high protein content demonstrates superior emulsifying and thickening performance, making it suitable for the formulation of topically applied skin preparations-such as creams and lotions-that possess excellent stability. Conversely, hydrolyzed keratin with a molecular weight below 1,000 Da lacks the requisite surface-active properties to form stable emulsions.
This finding suggests that by selecting keratin protein hydrolyzed with appropriate molecular weight specifications, formulators can precisely control a product's texture, spreadability, and skin feel. Furthermore, given that hydrolyzed keratin shares a highly similar amino acid composition with human skin keratin, it is capable of forming a moisturizing protective film on the skin's surface, thereby aiding in the maintenance of the skin barrier function.
