- Conclusions:
- The genetic toxicity of Magnesium perchlorate was predicted with OECD QSAR Toolbox v4.3.1 using experimental results of the analogue Lithium perchlorate (CAS 7791-03-9). Since the perchlorate is considered to trigger the toxicity, this approach is justified. The prediction is negative.
Predictions by the OECD QSAR Toolbox v4.3.1 with experimental result(s) of closely related perchlorate with CAS 7791-03-9 contained therein are used to address the endpoint, which is entirely appropriate to draw conclusions on the genetic toxicity of Magnesium perchlorate. - Executive summary:
The genetic toxicity of Magnesium perchlorate was predicted with OECD QSAR Toolbox v4.3.1 using experimental results of the analogue Lithium perchlorate (CAS 7791-03-9). Since the perchlorate is considered to trigger the toxicity, this approach is justified. The prediction is negative.
Predictions by the OECD QSAR Toolbox v4.3.1 with experimental result(s) of closely related perchlorate with CAS 7791-03-9 contained therein are used to address the endpoint, which is entirely appropriate to draw conclusions on the genetic toxicity of Magnesium perchlorate.

Additional information
Genetic toxicity of Magnesium perchlorate was predicted with OECD QSAR Toolbox v4.3.1 using experimental results of the closely analogue substance Lithium perchlorate (CAS 7791-03-9). This analogue substance was tested in vitro for its genetic toxicity according to OECD TG 471 (GLP). Since the perchlorate is considered to trigger the toxicity, this approach is justified and considered as entirely appropriate to draw conclusions on the genetic toxicity of Magnesium perchlorate. However, the registrant is prepared to conduct an experimental study but considered it as not necessary at first instance taking into account the available results.
Justification for classification or non-classification
Magnesium perchlorate was predicted to be not mutagenic by OECD QSAR Toolbox v4.3.1, based on in vitro results (AMES) of the closely analogue substance Sodium perchlorate. Hence, Magnesium perchlorate does not require classification according to Regulation (EC) No. 1272/2008.
