Toxicity to reproduction
Administrative data
- Endpoint:
- reproductive toxicity, other
- Remarks:
- Not specified
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The following prediction was performed using the OECD QSAR Toolbox. A category was formed based on the current endpoint (DART scheme). The prediction was further refined from a large database of metadata based on relevant subcategories.
- Justification for type of information:
- The test material is a mixture of many substances. Comparison of all substances has shown that they are expected to have the same reprotoxicity. For the purpose of addressing the reprotoxicity endpoint the most concentrated component of the test material was assessed individually.
Cross-reference
- Reason / purpose for cross-reference:
- other: read-across target
Reference
- Endpoint:
- reproductive toxicity, other
- Remarks:
- Not specified
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- For the justification for read-across, please refer to the read-across assessment framework report that is attached to Section 13.

- Remarks:
- The prediction was based on the average value from the 10 nearest neighbours compared by prediction descriptors.
- Critical effects observed:
- not specified
- Reproductive effects observed:
- no
- Conclusions:
- Based on the modelled conditions, the reprotoxicity NOEL of the test material in the rat was determined to be ca. 440 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 is within the applicability domain.
Based on the modelled conditions, the reprotoxicity NOEL of the test material in the rat was determined to be ca. 440 mg/kg bw/day.
