Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
airtight storage required, GOS slowly reacts with CO2 and H2O in air
Additional information
observations made in
IR: Increasing absorptions appearing with increasing time show the influence of contact with air and can probably be assigned to reaction products of Gd2O2S with CO2 and H2O in the air
and
Granulometry: slow chemical alteration in contact with water
In the granulometry a slight tendency of agglomeration of larger particles is observed, which might be due to the small amount of water contained in the dispersion agent causing a chemical alteration of the particles’ surface and particle agglomeration after several minutes.
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.
