Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information


The soil sorption organic carbon normalised partition coefficient values (Koc) of Bisphenol A range from 251 to 1507 L/kg, averaging 750 +/- 348 L/kg.

Henry´s Law constant:

At ambient temperature and atmospheric pressure, Bisphenol A is not volatile, with a Henry's law constant calculated to be 3.12E-7 Pa*m3/mol from aqueous solubility and vapour pressure.

Distribution modelling:

Level III Mackay-type modelling shows that nearly all Bisphenol A goes into the water and soil compartments. The exact proportion in each depends on where emissions enter the environment.
