Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justification for classification or non-classification

Zinc selenite did not show a significant or dose-dependent increase in mutations in cultured mouse lymphoma cells (L5178Y) up to the maximum dose of 120 µg/mL.

Based on the weight of the evidence from the existing in vitro and in vivo genotoxicity assays with zinc and selenium compounds, it is concluded that zinc selenite does not have biologically relevant genotoxic activity. Consequently, no classification for germ cell mutagenicity is applicable.

This conclusion is in line with those achieved by other regulatory reviews of the genotoxicity of zinc compounds (WHO, 2001; SCF, 2003; EU RAR, 2004, MAK, 2009). Hence, no classification and labelling for mutagenicity is required.
