About

1-ethyl-3-methoxy-tricycloheptane is a cosmetic ingredient used in product formulations. Note: classified as harmful to aquatic environments. Exercise caution due to limited available safety data.

1-Ethyl-3-methoxy-tricycloheptane is a bridged cyclic compound used as a fragrance ingredient, imparting woody or amber notes. Its H411 classification (toxic to aquatic life with long-lasting effects) requires environmental risk consideration in product disposal and formulation. Under EU Regulation 1223/2009, ingredients classified as H411 require aquatic hazard labeling and the SCCS recommends minimizing aquatic release. Fragrance Industry reviews indicate low dermal absorption for polycyclic alkane derivatives, but the tricyclic structure warrants additional battery of genotoxicity testing.

Known concerns

  • Toxic to aquatic life with long lasting effects (H411)
  • Persistence in environment - not readily biodegradable
  • Limited aquatic toxicity endpoint data
