Administrative data

Endpoint:
screening for reproductive / developmental toxicity
Remarks:
other: Car-SAR SAR model for Human Developmental Toxicity
Type of information:
(Q)SAR
Adequacy of study:
key study
Study period:
2014
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
A validated qualitative SAR model was used to predict whether the test material was active in a model of human developmental toxicity. The result of the modeling exercise was a determination that the substance is not a developmental toxicant. This modeled conclusion and associated documents are satisfactory for meeting the registration obligation of EU Regulation No. 1907/2006, and are adequate for the needs of classification and labeling and risk assessment. Cat-SAR Human Developmental Toxicity 8-22-2014(QMRF 1.1) is a well acknowledged data- and information-intensive SAR expert system. Food and Drug Administration’s (FDA’s) Center for Drug Evaluation and Research (CDER) is actively using this model to explore their application in drug evaluations.

Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6

Applicant's summary and conclusion

Conclusions:
The Cat-SAR model was used to assess reprotoxicity of 2-Propanol, 1-[(2-hydroxyethyl)thio]-3-(octyloxy)-, respectively 1-Octanol reaction products with epichlorhydrin and 2-mercaptoethanol, and it is predicted that the molecule has no structural features associated with reproductive toxicity.
It is predicted to be in the category: "Non Developmental Toxin".
