Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with column 2 of REACH Annex VIII, a study does not need to be conducted as based on the physicochemical properties the substance can be expected have a low potential for adsorption (on the basis of known constituents yielding logPow values between 1.46 and 3.4). The QSAR determination of the carbon partition coefficient for diphenyl carbonate using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed values of 227 L/kg (logKow method) and 1213 L/kg (MCI method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program (Schwab, 2011a; Schwab, 2011b; Schwab, 2011c).

Additional information
In accordance with column 2 of REACH Annex VIII, a study does not need to be conducted as based on the physicochemical properties the substance can be expected have a low potential for adsorption (on the basis of known constituents yielding logPow values between 1.46 and 3.4).
Diphenyl carbonate:
The QSAR determination of the carbon partition coefficient for of diphenyl carbonate using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed values of 227 L/kg (logKow method) and 1213 L/kg (MCI method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
4,4'-isopropylidenediphenol:
The QSAR determination of the carbon partition coefficient for 4,4'-isopropylidenediphenol using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed values of 1379 L/kg (logKow method) and 37700 L/kg (MCI method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
Phenol:
The QSAR determination of the carbon partition coefficient for phenol using the model KOCWIN included in the Estimation Program Interface (EPI) Suite v4.1 revealed values of 79 L/kg (logKow method) and 187 L/kg (MCI method) for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
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).
