2-Propyn-1-ol, reaction product with 1-2.5 moles of oxirane

Developmental toxicity / teratogenicity

Administrative data

Endpoint:

developmental toxicity

Type of information:

experimental study planned

Study period:

to be determined by ECHA

Justification for type of information:

The substance is handled in the EU at volumes of 100 - 1000 tons per annum and therefore, data requirements of Annex X of EC regulation 1907/2006 need to be met.
Since no adaptations to the standard testing requirement can be applied, the registrant proposes to perform an teratogenicity study (OECD 414).


NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Name of the substance on which testing is proposed to be carried out: 2-Propyn-1-ol, reaction product with oxirane (1-2.5 mol)

CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION [please address all points below]:
- Available GLP studies: No GLP study fulfilling the requirements of OECD 414 for the target substance is known to the registrant
- Available non-GLP studies: No non-GLP study fulfilling the requirements of OECD 414 for the target substance is known to the registrant
- Historical human data: No human historical data is known to the registrant
- (Q)SAR: No reliable and adequate (Q)SAR model for this endpoint is known to the registrant.
- In vitro methods: No reliable and adequate in-vitro methods for this endpoint are known to the registrant.
- Weight of evidence: In the absence of the above data, a weight of evidence assessment is not possible.
- Grouping and read-across: No structural analogues with experimental data fulfilling the requirements of OECD 414 for the target substance could be identified by the registrant.
- Substance-tailored exposure driven testing: not applicable
- Approaches in addition to above: not applicable
- Other reasons:not applicable

CONSIDERATIONS THAT THE SPECIFIC ADAPTATION POSSIBILITIES OF ANNEXES VI TO X (AND COLUMN 2 THEREOF) OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
The substance does not meet the criteria of specific adaptation possibilities of Annex VI to X and coloumn 2 thereof.
