Endpoint:
oxidising solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Description of key information

According to an expert statement by the German Federal Institute for Materials Research and Testing (BAM), based on experience of BAM with comparable substances, oxidising properties of As2O3 can be excluded (statement attached to the endpoint record in the technical dossier). This is also supported by an already existing IUCLID dataset, created 18-Feb-2000 by the European Commission (European Chemicals Bureau) based on data reported by industry following Council Regulation (EEC) No. 793/93. Thus, new testing for oxidising properties is not justified and diarsenic trioxide is not classified as an oxidising solid acc. to Regulation (EC) No. 1272/2008.

Key value for chemical safety assessment

Oxidising properties:
non oxidising
