Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Monoisopropylnaphthalene produced acute toxic effects on daphnia within the range of water solubility (=< 2.8 mg/L): In a valid 48 h short-term toxicity test (OECD 202), the EC50 was below 1 mg/L.

Key value for chemical safety assessment
