About KERATINASE
A proteolytic enzyme that degrades keratin, used in cosmetics for exfoliation and hair softening, but with potential skin irritation concerns.
Detailed Analysis
Keratinase is a proteolytic enzyme produced by various microorganisms that catalyses keratin hydrolysis. Not specifically restricted in EU Regulation 1223/2009, but as a proteolytic enzyme it carries inherent sensitisation potential. The EU SCCS has noted concerns about enzyme-based cosmetic ingredients regarding skin and respiratory sensitisation. Concentration should be controlled and appropriate preservation is essential.
