The prediction was based on dataset comprised from the following descriptors: NOEL

Estimation method: Takes average value from the 5 nearest neighbours

Domain logical expression: Result: Outside of applicability domain, but analogues used in prediction are considered to be adequately similar.

Substances used for the prediction should be:

Carboxylic acid<OR>Organic amide and thioamide<OR>Surfactants - Anionic (Organic functional groups)

Not known precedent reproductive and developmental toxic potential (DART scheme)

Non binder, non cyclic structure (Estrogen Receptor Binding)

Group 14 - Carbon C; Group 15 - Nitrogen N; Group 16 - Oxygen O (Chemical elements)

Conclusions:
Based on the modelled conditions, the Reprotoxicity NOEL of the test material in the rat was determined to be ca. 299 mg/kg bw/day.
Executive summary:

The reprotoxicity of the test material was evaluated using a read-across approach. Suitable analogues were found in the OECD QSAR Toolbox using the Organic functional group, and the results were refined using relevant subcategories (DART scheme, estrogen receptor binding, chemical elements).

The target chemical falls outside of applicability domain, but analogues used in prediction are considered to be adequately similar.

Reprotoxicity of the target chemical NOEL in rat of 299 mg/kg bw/day is derived by read across from the predictions carried out on the individual substance.

Conclusions:
Based on the modelled conditions, the reprotoxicity NOEL of the test material in the rat was determined to be ca. 299 mg/kg bw/day.
Executive summary:

The potential of the component present at the highest concentration in the test material to cause reprotoxicity was modelled using the OECD Toolbox. The NOEL was predicted to be 299 mg/kg bw/day. It has been shown, using read across, that all components are expected to have the same toxicity. Therefore, the reprotoxicity NOEL of the target chemical in rat is predicted to be 299 mg/kg bw/day.

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.
