Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The value for water solubility of this UVCB substance is based on a weight of evidence using QSAR data for its main constituents.

The water solubilities for three main constituents of this UVCB substance were determined by two appropriate QSAR calculation methods (WSKOWWIN and WATERNT):

water solubility for Polycyclic trimer: 9.385 E-18 mg/L (WSKOWWIN) and 8.454 E-7 mg/L (WATERNT);

water solubility for Polycyclic trimer: 1.422 E-18 mg/L (WSKOWWIN) and 8.4741 E-7 mg/L (WATERNT);

water solubility for Polycyclic trimer: 8.276 E-19 mg/L (WSKOWWIN) and 8.4943 E-7 mg/L (WATERNT).

The estimated results show that the substance has a very low water solubility which is below the detection limit of any of current available analytical method. Therefore it is technically not possible to conduct the study and the water solubility of the substance is considered to be lower than 0.001 mg/L.
