Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ferrous salts

Ferrous sulphate is a reducing agent, which is likely to be a property of all ferrous salts. Exposure to heat and light speeds the oxidation to the ferric form up (Anon 1987). The ferrous kation is deemed unlikely to be further reduced and relevant oxidizing properties can be negated.

Justification for classification or non-classification

The following statement bases on DSD, the Commission Directive 2001/59/EC (28th ATP of Council Directive 67/548/EEC), and CLP (5th ATP of Regulation (EC) No 1272/2008 of the European Parliament and of the Council) as implementation of UN-GHS in the EU:

The submission item is considered non-oxidizing on the basis of its chemical nature and composition. Ferrous (Fe+2) salts are generally reducing rather than oxidizing agents.
