- Nóta Sodium dichromate and potassium dichromate have a harmonised classification carcinogenic 1B, mutagenic 1B and toxic for reproduction 1B according to the CLP Regulation. Both sodium and potassium dichromate are listed in Annex XIV to REACH and their use is therefore subject to authorisation. At the time of drafting this document, only one authorisation was granted to use sodium dichromate as mordant in wool dyeing. During the dyeing processes with chrome dyes, Cr(VI) is reduced to Cr(III) if the process is under control. Nevertheless, emissions of Cr(VI) may still occur due to inappropriate handling of dichromate during dye preparation (care must be taken as dichromate is carcinogenic and may cause health problems for workers handling it). Emissions of trivalent chromium in the waste water can be minimised (see Section 4.5.3.1), but cannot be avoided, unless alternative dyestuffs are applied (see Section 4.5.3.1).
