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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
