Description of key information

One key study was identified: this assessed the long-term toxicity of  the chemical analogue linalool to Daphnia magna, in a 21-day reproduction study: a NOEC of 9.5 mg/l was determined.

Key value for chemical safety assessment

Fresh water invertebrates

9.5 mg/L

Additional information

Linalool is a close chemical analogue of dihydromyrcenol, with similar physico-chemical properties. Results of its testing for long-term toxicity to Daphnia are therefore deemed suitable to assess the equivalent toxicity of dihydromyrcenol. Linalool gave a 21 -day NOEC value of 9.5 mg/l: it is reasonable to assume that dihydromyrcenol would produce a similar response in freshwater invertebrates.
