Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Strontium hydroxide octahydrate: MMAD 30.47 µm GSD 1.64 µm
Strontium hydroxide octahydrate: D50 176.3 µm (Laser diffraction)

Additional information

It was decided not to conduct a study on particle size distribution and a dustiness testing with strontium hydroxide anhydrous but with the standard product available on the market. Hence, the results on MMAD/GSD determination could be used for evaluation and discussion on hazard potential of the marketable substance.
