What is Hydrolyzed keratin?
Hydrolyzed keratin is a water-soluble product that decomposes natural keratin (mainly from wool, feathers or human hair) into small molecular peptide chains through chemical or enzymatic processes, with a molecular weight range of 1-10 kDa. Its core characteristics include:
• Source:
• Animal source: wool (containing cystine ≥12%), feathers (low cost but contains impurities).
• Plant source: genetically modified microorganisms expressing keratin (emerging technology, avoiding animal ethics disputes).
• Process:
• Alkaline hydrolysis: low cost but may destroy the amino acid structure (cystine loss rate ≤15%).
• Enzymatic hydrolysis: directional cutting of peptide chains (such as using Bacillus subtilis protease), retaining active fragments (purity ≥90%).
• Characteristics: light yellow to amber liquid or powder, pH 5.0-7.0, water solubility ≥50g/100mL.

1. Hair repair and protection
• Filling the hair scales: small peptides penetrate into the cortex and repair broken disulfide bonds (electron microscopy shows that the closure of the hair scales is increased by 40%).
• Heat damage resistance: reduce protein loss under 230ºC wind (damage rate is reduced by 30%).
2. Skin barrier strengthening
• Activate the synthesis of filaggrin in the epidermis and increase the water content of the stratum corneum (TEWL decreases by 20%).
• Inhibit matrix metalloproteinase (MMP-1) and delay photoaging
3. Nail strengthening
• Penetrate into the nail plate to increase hardness (nanoindentation test shows that hardness increases by 25%) and toughness.
4. Application of environmentally friendly materials
• As a raw material for biodegradable films (tensile strength ≥ 50MPa), replacing petrochemical plastics.
1. Hair care products
• Shampoo: Add 1-3% hydrolyzed keratin (liquid) + cationic conditioner to reduce frizz.
• Hair mask: 5-8% high-concentration formula (powder compound) to repair perm and dye damage (once a week, 4 weeks to reduce split ends by 60%).
2. Skin care products
• Barrier repair cream: 2% hydrolyzed keratin + ceramide, for sensitive skin (reduce erythema area by 30%).
• Anti-aging essence: Nanoliposome encapsulated keratin peptide (particle size ≤100nm) to improve transdermal absorption rate.
3. Nail products
• Nail strengthening base oil: 3% keratin peptide + calcium, used twice a week, nail surface cracks reduced by 50% after 4 weeks.
4. Industrial materials
• Bioadhesive: Keratin-based glue (bonding strength ≥3MPa), used for wood and leather processing.
