About
A human-sourced antimicrobial enzyme protein that is restricted in cosmetic applications under EU Regulation (EC) No 1223/2009 Annex II.
Human Lysozyme is an antimicrobial enzyme (mucopeptide N-acetylmuramoylhydrolase, EC 3.2.1.17) isolated from human bodily secretions including tears, saliva, and milk. It is listed under EU cosmetics regulation restriction code II/416, indicating it appears in Annex II of Regulation (EC) No 1223/2009 — the list of substances prohibited in cosmetic products. This prohibition likely relates to its biological activity, potential for immune sensitization, and the regulatory principle that human-derived materials require particular safety scrutiny in cosmetic formulations.
Known concerns
- EU Annex II restricted — prohibited in cosmetic products
- Biological protein with potential immune sensitization risk
- Human-derived material with regulatory safety concerns
