Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

acute toxicity: dermal
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
Justification for type of information:
The physiochemical properties of MnO suggest it is unlikely to be absorbed through the skin. It has very poor water solubility and inorganic ions do not pass easily through the dermal barrier. In addition, MnO is not acutely toxic by the oral route and therefore it is highly unlikely that it would be toxic via the dermal route which in general absorbs chemicals to a much lesser degree than the gastrointestinal tract. Therefore in accordance with Annex VIII, section 8.5.3 column 2 adaptation, this test is not considered scientifically justified.
