Additional information

Justification for selection of repeated dose toxicity via oral route - systemic effects endpoint:

Reliable GLP study for the analogue substance KH2PO3/K2HPO3.

Justification for classification or non-classification

Repeated oral toxicity

The substance is not classified orally toxic because it doesn't meet the classification criteria of the CLP regulation n. 1272/2008 on repeated exposure:

No oral repeated toxicity on organs was predicted up to 776 mg/kg bw/day for Magnesium dihydrogenphosphite.
