Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Details on test material:
As per Vinyl Neodeconoate IUCLID4 Data Set


Target gene:
his -
Species / strain
Species / strain / cell type:
S. typhimurium TA 1535, TA 1537, TA 98 and TA 100
Additional strain / cell type characteristics:
other: Salmonella typhimurium and Escherischia coli strains WP2 and WP2 uvr A were also included in the assay.
Metabolic activation:
with and without
Metabolic activation system:
Rat liver S-9 fraction.
Test concentrations with justification for top dose:
Final concentrations were: 31.25, 62.5, 125, 250, 1000, 2000, or 4000 µg/plate.
Vehicle / solvent:
Details on test system and experimental conditions:
Bacterial tester strains were grown overnight at 37C with shaking. Rat liver S-9 metabolic activation system was prepared and maintained on ice until used. Molten top agar was maintained at 39-40C before plating. Test substance dilution, 0.1 ml of appropriate bacterial culture and rat liver S-9 fraction as needed were added to the top agar test tubes. The tubes were vortexed to mix and the contents were poured over minimal glucose agar plates. The plates in triplicate per dose were then incubated at 37°C for 48 hr before the revertant colonies were counted. The bacterial tester strains were tested with specific positive control substances to assure the sensitivity of the assay. After 48 hours of incubation the plates were counted by a automatic colony counter.
Evaluation criteria:
No data
Not required for this study.

Results and discussion

Test results
Species / strain:
S. typhimurium TA 1535, TA 1537, TA 98 and TA 100
Metabolic activation:
with and without
Cytotoxicity / choice of top concentrations:
no cytotoxicity
Additional information on results:
Vinyl Neodeconoate did not cause an increase in the background control mutant frequency values of any of the bacterial tester strains with or without rat liver S-9 metabolic activation system when tested up to the high dose level of 4 mg/mL. .
Remarks on result:

Applicant's summary and conclusion

Interpretation of results (migrated information):

Vinyl Neodeconoate did not cause gene-mutation in any of the Salmonella or E. coli tester strains under the conditions of the assay.
Executive summary:

When evaluated in an O.E.C.D. 471 "Bacterial Reverse Mutation Test" Vinyl Neodecanoate did not induce an increase of the mutant frequency in any of the tester strains. Therefore, Vinyl Neodecanoate is not a bacterial mutagen under the conditions of the assay.
