Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The observed particles were irregular and crystalline in nature.

 

The results indicated that 0.3% w/w of the test material was smaller than 10 µm.

 

Description of key information

0.3% w/w of the test material is < 10 µm (OECD 110)
