Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

Toxicity data are available for all three trophic levels in the aquatic compartment (primary producers/algae; invertebrates/Daphnia; fish). Acute toxicity has been directly investigated in algae and Daphnia, and studies of a close chemical analogue of the test item (linalool) provide information on acute toxicity to fish and long-term toxicity to Daphnia. Fish were by a small margin most sensitive, giving a 96h LC50 value of 27.8 mg/l (for linalool). Daphnia magna and algal growth inhibition studies with the test item gave EC50s of 38 mg/l and 80 mg/l (growth rate) respectively.

In a 21-day Daphnia reproduction study, the close analogue linalool gave a NOEC value of 9.5 mg/l, suggesting that the chronic toxicity of the test item to aquatic organisms will be relatively low.

Justification for the use of linalool as a read-across analogue of the test item is provided by the following considerations:

- both are linear (non-cyclic), unsaturated terpenoid tertiary alcohols

- their physical properties are generally similar (liquids at NTP, with boiling points circa 190-200°C, vapour pressures circa 0.2-0.3 hPa and water solubilities >800 mg/l. Log Kow values closely similar at 2.97 and 3.25).
