Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Tetrabutylammonium hydrogen sulphate is a stable,hygroscopic, white solid at 101325 Pa and 20 °C.
No experimental data are available for the substance.
Estimated data were calculated by EPI Suite 4.1.:
- predicted melting point is 256.47 °C;
- predicted boiling point is 593.92 °C;
- predicted vapour pressure is 9.06 *10^-14 Pa at T= 25°C;
- predicted partition coefficient n-octanol/water is log Kow= 0.96 at T= 25°C;
- predicted water solubility is 1081 mg/l at 25°C
TBHS is a cationic (quaternary ammonium) surfactant.
Since it is a solid, flash point can be waived.
Tetrabutyl ammonium hydrogen sulphate is not expected to be explosive based on its structure.
Tetrabutyl ammonium hydrogen sulphate is not expected to be strong oxidizing agent: TBHS contains bonds sulphur-oxygen but the oxygen balance is negative.
The pH of the water solution 55% is 1.5.
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.
