Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Since the substance is a UVCB substance with the main components 4,4'-isopropylidenediphenol, phenol and diphenyl carbonate, the partition coefficient is given as a range of these substances: log Kow = 1.46 - 3.4.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.4
- at the temperature of:
- 21.5 °C
Additional information
The substance was shown to mainly consist of 4,4'-isopropylidenediphenol, phenol and diphenyl carbonate whereas the individual components are characterised by the following octanol-water partition coefficients:
4,4'-isopropylidenediphenol: 3.4
Phenol: 1.46
Diphenyl carbonate: 3.28
Octanol-water partition coefficients are commonly measured applying the HPLC or the shake-flask methods. Nevertheless, the experimental determination of the octanol-water partition coefficient of the whole substance is hampered due to its complex nature. Therefore, the partition behaviour can preferably be described by logPow values of identified components.
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.
