Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Since no data on the toxicity of 3,7-dimethyloctan-1-ol to fish, aquatic plants and microorganisms are available the assessment of these endpoints are based on data for 3,7-dimethyloctan-3-ol, a close structural analogon. For aquatic invertebrates however, toxicity data is available.

The most sensitive organism regarding acute toxicity is Daphnia magna with an EC50 of 3.6 mg/L (measured geometric mean EC100 / EC0). LC50 and EC50 for fish and algae were determined to be quite similar (LC50 fish: 22 mg/L; EC50 algae: 21.6 mg/L), respectively.

The PNEC calculations are based on the results of the acute toxicity test performed with Daphnia magna.

The PNEC STP was calculated using the EC10 of 450 mg/l determined in a respiration inhibition test conducted with Pseudomonas putida.
