Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The soluble amount of the constituent sulphur of the test item in water at a temperature of 20°C was determined to 614, 635 and 641 mg/L, respectively. The corresponding mean value is 630 mg/L. This is not a limit value, because the amount of sulphur in the water extracts of sulphuric acid, compound with graphite is directly correlated to the weight of sample taken to produce the water extracts. 

Key value for chemical safety assessment
