Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The calculation rule was furhter applied for the impurities of the monoconstituent. As demonstrated in the table below, calculation does not lead to an acute toxicity category for Caldium stannate.

In conclusion, Ca stannate does not fulfill the classification criteria for oral acute toxicity

Calculation of the acute oral toxicity of the monoconstuent substance Ca stannate

FORMULA: 100/ATEmix = ∑ (Ci/ATEi)(CLP

ATE = acute toxicity estimate

Ci=concentration of component i (%w/w)


Concentration (max. %) (Ci)

Classification for acute oral toxicity

Relevant for acute toxicity calculation

ATE orl (mg/kg)

Ci/ATEi orl

Ca stannaat


not classified (LD50 > 2000 mg/kg) based on read across from SnO2

no, ingredients that are presumed not acutely toxic should be ignored (CLP

not applicable

not relevant

Ca arsenate


acute tox 3

yes, the concentration is above the cut-off value of 0.1% (CLP table 1.1)



∑ (Ci/ATEi)




Conclusion on the classification of the monoconstituent substance Calcium stannate:

ATEmix > 2000 mg/kg, so the substance does not fulfill the classification criteria for oral acute toxicity

Justification for classification or non-classification

Calcium stannate  does not fulfill the classification criteria for oral acute toxicity.
