Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

PNECs considering the reference substance were deduced from the water solubility for each compartment/endpoint as it represents a worst-case scenario.

Conclusion on classification

According to the aquatic toxicity data no hazard was detected for all three trophic levels as well as for microorganisms. But as Poly-1,4-Diisopropylbenzene is highly insoluble in water, has a log Pow greater than 6 and is not readily biodegradable it needs to be classified as aquatic chronic cat. 4 (H413: May cause long lasting harmful effects to aquatic life) according to Regulation (EC) No 1272/2008 and as R53 (May cause long-term adverse effects in the aquatic environment) according to Directive 67/548/EC.
