Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Henry's Law Constant characterizes the equilibrium distribution of dilute concentrations of volatile, soluble chemicals between the gas and liquid phases. The hydrotropes are not volatile chemicals and therefore estimating a Henry's Law Constant is not feasible or relevant.
Key value for chemical safety assessment
Additional information
Vapour pressure, a measure of volatility, is not required under REACH for substances with a melting point above 300°C. A 2009 melting point ISO Guideline study of a closely related substance, sodium cumene sulphonate, reported there was no decomposition and no sublimation at up to 350°C and 1 atm. The measurements were done in triplicate. Hydrotropes are not volatile substances.
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.
