Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No data on acute toxicity to fish is available for the target substance.  Data from the alkylbenzene derivatives were used to understand the acute toxicity profile of the substance to fish. The toxicity with freshwater fish has been measured experimentally for multiple category members. Based on the worst case approach, the 96 -h LC50 value is considered > 1.67 mg a.i./L.  The target substance has a very low water solubility demonstrated with QSAR modelling. Furthermore EPISUITE QSAR modelling was used to predict the acute toxicity profile of the target substance. Modelled toxicity values for the target substance confirmed that the aquatic acute toxicity value exceeds the predicted water solubility, leading to the conclusion that it doesn't exhibit acute aquatic toxicity. It can be concluded that the target substance does not demonstrate acute aquatic toxicity at water soluble concentrations.
