Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law constant
Administrative data
Link to relevant study record(s)
Description of key information
No experimental data are existing for the substances of the category. The Henry's law constant has been estimated with HENRYWIN v3.20, Bond method and the results are reported below:
BSA, CAS: 98-11-3; 2.55 e-004 Pa-m3/mole
TSA, CAS: 104-15-4; 2.81 e-004 Pa-m3/mole
XSA, CAS: 25321-41-9; 3.11E-004 Pa-m3/mole
CSA, CAS: 16066-35-6; 4.96 e-004 Pa-m3/mole
HBSA, CAS: 98-67-9; 2.65 e-008 Pa-m3/mole
The value of HBSA has been selected as representative key value of the category for the Chemical Safety Assessment
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 25 °C
Additional information
Henry's Law Constant characterizes the equilibrium of dilute concentrations of volatile, soluble substances between the gas and liquid phases. The aromatic sulphonic acids are not volatile and therefore a Henry's Law Constant is not feasible or relevant. An indicative value to complete the Chemical safety assessment has been calculated with EPIWIN 4.1. The value 0.0000000265 has been reported as key value for safety assessment, as conservative case.
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.
