Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Koc range 9010 - 1.00E+10 L/kg; log Koc range 3.9547 - 18.1711 [KOCWIN v2.00 (EPIWIN software by US-EPA)]

Key value for chemical safety assessment

Additional information

The prediction for soil adsorption potential of the UVCB substance reaction products of phosphorous trichloride, with 1,1′-biphenyl and 2,4-bis(1,1- dimethylethyl)phenol was determined by the KOCWIN program (v2.00) made available by U.S. Environmental Protection Agency (based on the low water solubility and the complexity of the substance, an experimental study was considered inappropriate). Values have been estimated for the individual constituents of the UVCB substance, resulting in a Koc range of 9010 to 1.00E+10 L/kg (Log Koc range of 3.9547 to 18.1711) for the chemical compound. These results are indicative of a high sorption potential onto soil organic matter for the majority of the UVCB substance, which has been expected given the low water solubility.
