- Conclusions:
- Interpretation of results (migrated information):
negative
In conclusion, in the described mutagenicity test under the experimental conditions
reported, the test item Bornan-2-one (EC# 200-945-0, CAS# 76-22-2) is considered to
be non-mutagenic in the in vitro mammalian cell gene mutation assay (thymidine kinase
locus) in mouse lymphoma L5178Y cells.
