Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Uronium hydrogen sulphate and its degradation products in the environment (urea and sulfates) has a low potential for adsorption:
- Urea has a log octanol water partition coefficient less than 3 (ca -1.56) and has low potential for adsorption ;
- Sulfates dissociate into the cation (e.g. Ca2+) and sulfate SO42- ions at environmental pH. The sulfate ion is sufficiently mobile to penetrate soil readily.

Key value for chemical safety assessment
