Hydrolyzed Keratin Cosmetic Ingredients

The Core RevelationHuman hair is 80-90% keratin – a protein fortified by disulfide bonds (S-S bridges) that grant elasticity and strength. Yet chemical damage ruptures these bonds, causing: ⚠️ 12-13% moisture loss (vs. healthy hair) ⚠️ Cracked cuticles exposing cortical proteins ⚠️ Reduced light reflectance (dullness) Enter DropCare® Hydr-KP (powder) and Hydr-KPL (liquid) – engineered keratin solutions that rebuild hair from within. 3 Mechanisms of Action Structural Reconstruction Binds to exposed cysteine residues via hydrogen bonds Reforms disulfide crosslinks in cortex (SEM-proven): 5% concentration: 40% cuticle closure 20% concentration: 95% cuticle repair Moisture LockRestores water-holding capacity by 63% (vs. bleached hair):Bleached hair recovers 80% hydration after keratin treatment (Barba et al.) Lipid-Protein Matrix RestorationReplenishes ceramides & fatty acids lost during damage: 17.8% cysteine recovery 11.7% serine regeneration Product Specifications Parameter Hydr-KP (Powder) Hydr-KP Liquid Protein Content ≥80% 30-38% dry residue pH 4.5-6.5 4.0-6.0 Key Application Shampoos (0.1-1%) Conditioners (3-8%) Damage Repair Up to 5% concentration Up to 15% concentration Preservation 3-year stability Phenoxyethanol system (1y) Why Formulators Choose DropCare®KP&KPL Dual-Action Efficacy INCI: Hair/Skin Conditioning Agent (EC 1223/2009 compliant) Anti-aging properties via peptide signaling (KPL variant) Market-Driven Demand52% of consumers pay premium for "problem-solving ingredients" – our keratin targets: Split end reduction (89% efficacy at 12.5% conc.)
