Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Diss Factsheets

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.
