Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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)
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- The Henry’s law constant (HLC) is directly calculated as the ratio of the vapor pressure to the water solubility (experimental values).
- GLP compliance:
- no
- Key result
- H:
- < 0 other: hPam³/mol
- Remarks on result:
- other: calculated value, no temperature and pressure measured
- Executive summary:
The Henry's law constant of N-cyclohexylbenzothiazole-2-sulphenamide is <3.74*10-4 hPa m3/mol, which was directly estimated as the ratio between the vapour pressure and water solubility (Currenta, 2021).
Reference
at ambient temperature (e.g. 21 -25°C)
Description of key information
The Henry's law constant (HLC) of N-cyclohexylbenzothiazole-2-sulphenamide (CBS) is lower than 3.74*10-4 hPa m3/mol at ambient temperature (e. g. 21 -25°C), which is directly estimated as the ratio between the vapour pressure and water solubility (Currenta, 2021). Therefore CBS is essentially non-volatile. Most of the described metabolites of CBS, such as MBT, MBTS, BTon, BT, and MeSBT are are also non-volative, but only MeBT has an estimated HLC of 2.75 Pa m3/mol, which is higher than 1 Pa m3/mol and hence considered as slightly volatile.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 23 °C
Additional information
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.
