Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Since data for the test substance hydroxylamine-O-sulphonic acid (CAS 2950-43-8) are not available, information on the surrogate substance bis(hydroxylammonium) sulfate (CAS 10039-54-0) are used in a reliable read-across approach to evaluate the test substance.
Normally, distribution of a substance in the environment can be estimated using a Mackay-type model. Since the surrogate substance bis(hydroxylammonium)sulphate is an inorganic substance dissociating in water, it is not reliable to estimate the distribution using a Mackay-type model. The surrogate substance does not exhibit any measurable vapour pressure. Taking into account the inorganic character of bis(hydroxylammonium)sulphate and its high solubility in water, a complete distribution to the aqueous compartment can be expected. Adsorption to organic matter is negligible.
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.
