Developmental toxicity / teratogenicity
Administrative data
- Endpoint:
- developmental toxicity
- Type of information:
- experimental study planned
- Study period:
- Awaiting ECHA approval
- Justification for type of information:
- CONSIDERATIONS OF ALTERNATIVE METHODS ON TESTING PROPOSALS IN YOUR REGISTRATION
PUBLIC SUBSTANCE NAME: Propylidynetrimethanol, ethoxylated, esters with acrylic acid, reaction products with diethylamine
EC NUMBER: 500-425-6
CAS NUMBER: 159034-91-0
DATE OF CONSIDERATIONS: 21 January 2021
Hazard endpoint for which vertebrate testing was proposed:
Reproductive toxicity (oral pre-natal developmental toxicity in rats, OECD TG no. 414) with the registered substance;
Considerations that the general adaptation possibilities of Annex XI of the REACH Regulation were not adequate to generate the necessary information
• available GLP studies: None.
• available non-GLP studies: None.
• historical human data: None.
• (Q)SAR
According to ECHA guidance R.7a (October 2015, page 382), QSAR approaches are currently not well fitted-for-purpose for reproductive toxicity and not all necessary aspects can be covered by a QSAR prediction.
• in vitro methods
In vitro reproduction studies are not available on the test substance.
Some in vitro test methods have been developped, however, according to Chapter R 7a (October 2015, page 381), the regulatory acceptance of these in vitro methods has not been achieved as they do not provide equivalent information.
• weight of evidence: No data is available which allow a weight of evidence approach.
• grouping and read-across: No data is available which allow a read across approach.
• substance-tailored exposure driven testing [if applicable]: Not applicable
• [approaches in addition to above [if applicable] : Not applicable
• other reasons [if applicable] :None
Considerations that the specific adaptation possibilities of Annexes VI to X (and column 2 thereof) were not applicable:
Test proposal is fully compliant with ECHA guidance R 7.a.
No specific adaptation possibilities of Annexes VI to X (and column 2 thereof) are applicable.

Results and discussion
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
