EC number: 940-029-4
CAS number: 1474044-86-4
The structural analog test substance, 2,3-epoxypropyl
neodecanoate was accessed for the potential to induce gene-mutation in
the in vivo MutaMouse test system up to an oral dose level of 1000 mg/kg
by an O.E.C.D. test guideline 488 study. The test substance is a
gene-mutagen in vivo in the MutaMouse. Treatment wiht the test substance
induced a statisticall significant, dose-related increase of the mutant
frequency in the liver, kidney and bone marrow of the MutaMouse. No
increase of the mutant frequency was observed in the developing and
mature sperm. Therefore, the test substance, 2,3-epoxypropyl
neodecanoate is a CLP Category 2 Mutagen, H341, "Suspected of causing
genetic defects". This Classification and Labeling is considered to be
appropriate for the subject of Registration, Neononanoic acid glycidyl
The test substance induced gene-mutations in Salmonella tester strain
TA1535 and E. coli strain WP2 uvrA. The increase in mutant frequency
relative to the control background value reach 8.6-fold in tester strain
TA1535 without S9 metabolic activation. The test substance neononanoic
acid glycidyl ester induced statistically significant dose-related
increases of the chromosome aberration frequency in Chinese hamster
cells with and without (20 hr exposure) rat liver S9 fraction metabolic
activation. The maximum increase of the chromosome aberration frequency
relative to the concurrent solvent control value was 11-12-fold. No
evidence of chromosome damage was observed in an O.E.C.D. test guideline
474 rat micronucleus study with the test substance when tested up to the
oral high dose of 2000 mg/kg of body weight.
The structural analog, 2,3-epoxypropyl
neodecanoate is a gene-mutagen in vivo in the MutaMouse. Treatment with
the test substance induced a statisticall significant, dose-related
increase of the mutant frequency in the liver, kidney and bone marrow of
Because the structural analog, 2,3-epoxypropyl neodecanoate is an in
vivo gene-mutagen in the MutaMouse and there is supporting in vitro
genetic toxicity data for Neononanoic
acid glycidyl ester, Classification and Labeling as per the CLP of Category
2 Mutagen, H341, "Suspected of causing genetic defects" is appropriate.
