Detailed Analysis
2,3-Epoxypropyl o-tolyl ether (o-cresyl glycidyl ether, CAS 2210-79-9, also known as 2,3-epoxypropyl o-tolyl ether) is a glycidyl ether of o-cresol. The EU COSING database shows multiple restriction entries: it shall not be placed on the market or used as a substance or in mixtures in concentrations equal to or greater than 0.1% by weight, and shall not be used as a propellant in aerosols for any use. Aerosol dispensers containing the substance as propellant shall not be placed on the market. The primary concerns are sensitisation potential and the epoxide group's reactivity with biological nucleophiles.
Known Concerns
- ⚠ EU Annex III restricted: prohibited above 0.1% in mixtures
- ⚠ Banned as aerosol propellant in EU
- ⚠ Skin sensitisation and potential mutagenicity concerns due to epoxide structure
