Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The data reported suggest that substance exhibited antimutagenic activity.
Link to relevant study records
Reference
Endpoint:
in vivo mammalian germ cell study: cytogenicity / chromosome aberration
Remarks:
Type of genotoxicity: chromosome aberration
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: A reliable publication, summarising derivative pharmaco-toxicological action, was used. However the substance of interest was not revisited in order to verify the contents; for this reason reliability score 2 was used.
Qualifier:
no guideline available
Principles of method if other than guideline:
It is not specified.
GLP compliance:
not specified
Type of assay:
chromosome aberration assay
Species:
mouse
Strain:
CBA
Sex:
female
Route of administration:
intraperitoneal
Vehicle:
corn oil
Duration of treatment / exposure:
single treatment 40 mg/kg bw
Remarks:
Doses / Concentrations:
40 mg/kg bw DMBA(7,12-Dimethylbenz[·]anthracene)
Basis:
nominal conc.
four groups
Remarks:
Doses / Concentrations:
50 mg/kg bw with test material
Basis:
nominal conc.
three of the four groups with test material
Remarks:
Doses / Concentrations:
1 ml/kg bw of corn oil
Basis:
nominal conc.
fifth group
Remarks:
Doses / Concentrations:
50 mg/kg bw of test material
Basis:
nominal conc.
sixth group
No. of animals per sex per dose:
six groups of six
Control animals:
yes, concurrent vehicle
Tissues and cell types examined:
thymus, spleen, liver, kidney, lung, bone marrow and lymph nodes
Sex:
female
Genotoxicity:
negative
Toxicity:
not specified
Vehicle controls validity:
not specified
Negative controls validity:
not specified
Positive controls validity:
not specified
Conclusions:
Interpretation of results (migrated information): negative
The data reported suggest that substance exhibited antimutagenic activity. The quality of information is scarce and the classification is inconclusive
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (negative)
