Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The Henry's law constant (HLC) of p-cresol at 25 °C is reported to be 0.1 Pa m³/mol.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0.1
- at the temperature of:
- 25 °C
Additional information
The distribution of p-cresol between aqueous solution and air is described by the Henry’s law constant.
For p-cresol two results for the Henry's Law Constant are reported.
A thermodynamic method was used to determine the Henry's law constant of p-cresol. At 25°C a value of 0.35 Pa*m³/mol was obtained. Another value of 0.1 Pa*m³/mol at 20°C was reported. The lowest value ist taken into account for assessment.
Both values indicate a low volatility for p-cresol from aqueous solution.
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.
