Administrative data

acute toxicity: dermal
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the physicochemical and toxicological properties suggest no potential for a significant rate of absorption through the skin
Justification for type of information:
The available physico-chemical data on magnesium potassium fluoride silicate (Mg2.7K0.7Si4O10F2) indicate that dermal absorption is highly unlikely. Further, a good-quality acute inhalation toxicity - the route of higher concern - study by the inhalation route is available.
