Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
in vivo mammalian somatic cell study: cytogenicity / erythrocyte micronucleus
Type of information:
experimental study planned
Justification for type of information:
TESTING PROPOSAL ON VERTEBRATE ANIMALS

NON-CONFIDENTIAL NAME OF SUBSTANCE:
CAPA 3050

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 studies are available
- Available non-GLP studies: no studies are available
- Historical human data: no data are available
- (Q)SAR: (Q)SAR predicitions will not be accepted in isolation
- In vitro methods: not applicable - the testing proposal is based on the results of an equivocal result in a study in vitro
- Weight of evidence: not applicable - the testing proposal is based on the results of an equivocal result in a study in vitro
- Grouping and read-across: not applicable. a previous proposal for read-across has been rejected by ECHA
- Substance-tailored exposure driven testing: not applicable
- Approaches in addition to above: 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 generation of genotoxicity data in vivo to clarify the results of a postive or equivocal result in vitro is a standard requirement under REACH and cannot be adapted for this substance based on any Column 2 or Annex XI adaptations.

FURTHER INFORMATION ON TESTING PROPOSAL IN ADDITION TO INFORMATION PROVIDED IN THE MATERIALS AND METHODS SECTION:
- Based on the equivocal response seen in the in vitro clastogenicity study, a mouse bone marrow micronucleus assay is proposed for CAPA 3050.
