What it is
Hydrolyzed Keratin is made by breaking down keratin protein into smaller peptides and amino acids that are soluble and substantive to skin and hair. In formulas it forms a light conditioning film and acts as a humectant, helping the surface feel smoother and more supple. In sunscreens it is included as a conditioning additive rather than as a sun-protective component.
Safety & warnings
Hydrolyzed keratin is generally well tolerated as a conditioning agent. As a protein hydrolysate it carries a low theoretical risk of sensitization in predisposed individuals.
Origin & sourcing
Derived from keratin protein, traditionally sourced from animal materials such as wool, feathers, or horn, then hydrolyzed into smaller peptides.
