About

A carbonate ester fragrance compound classified as H412 (harmful to aquatic life), common in fine fragrances and cosmetics.

2-tert-Butylcyclohexyl ethyl carbonate is a carbonate ester used as a fragrance ingredient for woody, herbaceous notes. Its H412 classification (harmful to aquatic life with long-lasting effects) triggers labeling requirements under EU Regulation 1272/2008 (CLP). The fragrance industry (IFRA) has issued environmental guidance for carbonate ingredients, recommending aquatic risk reduction measures. SCCS cosmetic reviews note low systemic toxicity but recommend skin sensitization testing for carbonate fragrances with H412 classification. The 0.1% trigger for IFRA declaration applies.

Known concerns

  • Harmful to aquatic life (H412) - environmental concern
  • May require IFRA sustainability declaration
  • Limited data on chronic aquatic toxicity
