Calcium sulfate has been shown to be non-genotoxic both in vitro and in
vivo. These observations indicate that calcium sulfate is not expected
to be a genotoxic carcinogen. Calcium sulfate has been examined in
repeat dose oral studies and has shown low levels of toxicity. There is
sufficient data to indicate that calcium sulfate does not pose a risk of
classification is warranted under CLP for carcinogenicity based on
evidence from genotoxicity and repeat dose studies.
There are no lifetime animal studies available on calcium sulfate
in order to directly investigate for possible carcinogenic activity. However,
calcium sulfate gave negative results in the in vitro and in vivo
genotoxicity studies. In repeat dose studies with calcium sulfate there
is no evidence that calcium sulfate is able to induce hyperplasia or
