Science
Mechanism of Action
This modified keratin exhibits high structural homology with human keratin, facilitating its interaction with skin cells similarly to the body's own keratin. By leveraging keratin's established biological roles in cellular growth, development, and repair, Oxidized Keratin aids in moisture binding and provides a protective layer, maintaining the skin in optimal physiological condition.

Stability
Oxidized Keratin is water-soluble, a characteristic achieved by the cleavage of disulfide bonds during its oxidation process. It maintains stability within a neutral pH range, typically between 5.0 and 7.0. Exposure to highly alkaline conditions can induce the breakdown of cystine and hydrolysis of amide bonds, while extreme acidity may compromise its thermal stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Oxidized Keratin and other keratin-derived ingredients are safe under current practices of use and concentration. However, it was explicitly noted in the 2015/2016 safety assessment that Oxidized Keratin was not widely reported to be in current cosmetic use. This limits practical data on widespread application, though the FDA has clarified that keratin derived from bovine sources is not among prohibited cosmetic materials.

Verdict
While assessed as safe by the CIR and possessing theoretical skin benefits, the absence of reported widespread cosmetic use and corresponding clinical efficacy data renders its practical utility currently underexplored.
