Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The water solubility of ESBO is estimated to be <0.02 µg/L, categorised as insoluble in REACH, see section 4.8 for details. Ideally aquatic toxicity studies should not be conducted above the limit of water solubility, the study reported here tested nominal concentrations up to 1000 mg/L. According to Annexes VII and VIII a Daphnia, fish and algal studies are required unless there are mitigating factors such as the test substance is insoluble, this is the case for ESBO.

Conclusion on classification

No classification is triggered based on available data, according to EEC Council Directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or Regulation (EC) No 1272/2008.
