Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance is very soluble in water (> 10 g/L at ambient temperature). In water, the substance hydrolyzes to give 3-hydroxopropanesulfonic acid. This reaction may be accelerated by acid.
Key value for chemical safety assessment
- Water solubility:
- 171 g/L
- at the temperature of:
- 25 °C
Additional information
As the substance has a very polar structure, it is assumed that substance is very soluble in water. This assumption is in line with observations during use. The high solubility of the substance in water which is a consequence of the polarity of the molecule due to its content in polar groups. Substances similar to the hydrolysis product are used as surfuctants in water.
The substance is very soluble in water but hydrolizes. No experimental testing is required.
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.
