Genetic toxicity: in vivo
Administrative data
- Endpoint:
- genetic toxicity in vivo, other
- Remarks:
- In vivo Single Cell Gel/Comet Assay
- Type of information:
- experimental study planned
- Justification for type of information:
- TESTING PROPOSAL ON VERTEBRATE ANIMALS
NON-CONFIDENTIAL NAME OF SUBSTANCE:
- Name of the substance on which testing is proposed to be carried out : Base terpenica
- Name of the substance for which the testing proposal will be used [if different from tested substance] : N/A
CONSIDERATIONS THAT THE GENERAL ADAPTATION POSSIBILITIES OF ANNEX XI OF THE REACH REGULATION ARE NOT ADEQUATE TO GENERATE THE NECESSARY INFORMATION:
- Available GLP studies : Not available.
- Available non-GLP studies : Not available.
- Historical human data: Not available.
- (Q)SAR: Not available.
- In vitro methods: In vitro methods are possitive
- Weight of evidence : Not available.
- Grouping and read-across : Not available. Substance UVCB.
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:
- One of the in vitro studies of genetic toxicity is positive, so according annex XI of REACH Regulation it is necessary to carry out an in vivo assay.
