About

3-ethyl-2-methyl-2-(3-methylbutyl)-1,3-oxazolidine is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This substituted oxazolidine carries an alarming hazard profile in the EU GHS classification system: H314 (causes severe skin burns and eye damage), H318 (causes serious eye damage), H336 (may cause drowsiness or dizziness), H360F (may damage fertility), H360 (reproductive toxicity), H400 (very toxic to aquatic life), and H410 (very toxic to aquatic life with long-lasting effects). The Danger signal word and CMR (carcinogenic, mutagenic, reprotoxic) classification precludes its use in cosmetic products marketed in the EU. It is not listed in any EU cosmetic Annex but its hazard profile strongly contraindicates any skin contact application.

Known concerns

  • H314/H318: Severe skin burns and serious eye damage
  • H360F/H360: Reproductive toxicity / may damage fertility (CMR concern)
  • H336: CNS effects (drowsiness/dizziness)
  • H400/H410: Very toxic to aquatic environment
  • Danger signal word — highest hazard category
