CAS number: 18479-58-8
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
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.
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
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).
