Materials and methods

Test guideline

Qualifier:

according to guideline

Guideline:

other: REACH guidance on QSARs R.6. May/July 2008

Principles of method if other than guideline:

This QSAR model is based on profiling results obtained by DART scheme v 1.0. This QSAR is used for identifying chemicals with structural features associated with the potential to act as reproductive or developmental toxicants. The outcome of the QSAR model is “Known precedent reproductive and developmental toxic potential”, if the chemical has a potential to cause toxicity. The corresponding category is displayed in the report generated for the obtained prediction. The other prediction results are “Not known precedent reproductive and developmental toxic potential” if the toxic potential of the input chemical is not known, and “Not covered by current version of the decision tree” if the identified structural features are not objects of the tree.

GLP compliance:

no

Remarks:

As no laboratory work took place, compliance with GLP is not required.

Toxicity of the target chemical (Not known precedent reproductive and developmental toxic potential) is predicted by QSAR "Developmental and Reproductive Toxicity (DART)". The current prediction has no applicability domain.

Applicant's summary and conclusion

Conclusions:

Toxicity of the target chemical was predicted by QSAR "Developmental and Reproductive Toxicity (DART)". The target chemical was predicted to fall under the category "Not known precedent reproductive and developmental toxic potential".

Executive summary:

The potential of the test material to cause reproductive or developmental toxicity was modelled using the OECD QSAR Toolbox. This QSAR model is based on profiling results obtained by DART scheme v 1.0. This QSAR is used for identifying chemicals with structural features associated with the potential to act as reproductive or developmental toxicants.

Toxicity of the target chemical was predicted by QSAR "Developmental and Reproductive Toxicity (DART)". The target chemical was predicted to fall under the category "Not known precedent reproductive and developmental toxic potential".
