Expert Verdict

CRITICAL — EPOXIDE STRUCTURAL ALERT. Naphthoxirene = naphthalene-fused oxirane. Epoxides are electrophilic, protein-reactive, and flagged for both genotoxicity and skin sensitisation. ECHA C&L notifications for related naphthoxirenes include H315 (skin irritation) and H411 (aquatic chronic toxicity). Mandatory testing before inclusion: Ames test, in-vitro micronucleus, DPRA, KeratinoSens, h-CLAT. Do NOT include in any CPSR without complete genotoxicity and sensitisation data.
