Trimethyl-3-[(1-oxo-10-undecenyl)amino]propylammonium methyl sulphate

Developmental toxicity / teratogenicity

Administrative data

Endpoint:

developmental toxicity

Type of information:

experimental study planned (based on read-across)

Study period:

Study planned to start within 6 months of final confirmation from ECHA

Justification for type of information:

TESTING PROPOSAL ON VERTEBRATE ANIMALS
- It should be noted that no new animal testing has been proposed for this substance. A new study on an analogue substance has been proposed and will be used for read-across to this substance when available.

NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Name of the substance on which testing is proposed to be carried out: 3-Lauramidopropyl trimethyl ammonium methyl sulfate (CAS No. 10595-49-0)
- Name of the substance for which the testing proposal will be used: trimethyl-3-[(1-oxo-10-undecenyl)amino]propylammonium methyl sulphate

CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION]:
- Available GLP studies: None available
- Available non-GLP studies: None available
- Historical human data: None available
- (Q)SAR: Not sufficiently robust for developmental toxicity, in particular compared to the option of read-across from an analogue substance.
- In vitro methods: Not sufficiently robust for developmental toxicity, in particular compared to the option of read-across from an analogue substance.
- Weight of evidence: No developmental toxicity studies available
- Grouping and read-across: A pre-natal developmental toxicity study has already been proposed on an analogue substance (methyl trimethyl-3-[(1-oxododecyl)amino]propylammonium sulphate; CAS 10595-49-0) which has already been used as a source substance for read-across. Therefore in order to make maximum use of the proposed study, it will also be used for read-across to this substance.
- 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:
- It should be noted that no new animal testing has been proposed for this substance. A new study on an analogue substance has been proposed and will be used for read-across to this substance when available.
