Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Effects on fertility
Additional information
No data are available on Uronium hydrogen sulphate.
However data available on its degradation products (sulphate salt and urea) in the human body show that Uronium hydrogen sulphate is very unlikely to be a reproductive toxin:
- Calcium sulfate dihydrate showed no signs of reproduction/developmental toxicity in an OECD 422 reproduction/developmental screening test (NOAEL = 790 mg/kg bw/day, as anhydrous).
- Urea is very unlikely to be a reproductive toxin; it is naturally produced in large quantities in the human body as a consequence of normal protein catabolism and has no effects after long term exposure, especially regarding reproductive organs.
Thus testing cannot be justified scientifically.
Justification for classification or non-classification
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.
