Appearance/physical state/colour: Bisphenol A is a while solid at environmentally relevant temperatures
Melting Point: 155 °C
Boiling Point at 17 hPa: 250 - 252 °C (with potential decomposition), Boiling Point at 1013 hPa: 360 °C (with decomposition)
Density: 1.2 g/cm3 at 25 °C
Vapour Pressure: 4.12E-09 hPa at 25 °C
Log Kow: 3.4 at 21.5 °C and pH 6.4
Water Solubility: 300 mg/L at 25 °C
Flash point: 227 °C at 1013 hPa
Auto-ignition temperature: 510 °C at 1013 hPa (decomposition starts at lower temperatures)

Bisphenol A is a white solid melting at 155 °C and boiling at 360 °C under decomposition. With a moderate water solubility of 300 mg/L and log Kow of 3.4, Bisphenol A is expected to adsorb somewhat to soil and sediment and not migrate through groundwater. With a pKa of 11.3, Bisphenol A is not expected to significantly dissociate in water at environmentally relevant pH values (5 to 8).
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.
