Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
Under REACH (ECHA 2008, Chapter R.7B – Endpoint Specific Guidance), the term ‘Hydrolysis’ refers to the “Decomposition or degradation of a chemical by reaction with water”, and this is a function of pH (i. e., abiotic degradation). Indium persists in the environment irrespective of whatever chemical species form as a result of hydrolysis, although it may form insoluble indium hydroxides that precipitate out of solution. Characterization of indium in environmental media is typically based on total indium concentrations inclusive of all specific chemical forms or species. Since hydrolysis changes the chemical form but does not decompose indium and since characterization of total indium considers all chemical forms, the concept of degradation of indium by hydrolysis is not relevant for its environmental fate.
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.
