Endpoint summary
Administrative data
Key value for chemical safety assessment
Genetic toxicity in vitro
Description of key information
Gene mutation : AMES TEST: The test substance, benzyl propionate did not induce mutagenicity in an Ames assay conducted on S. typhimurium TA 1535, TA 1537, TA 98, TA 100 and TA 102 strains with and without S9 activation.
From the comparison of the data obtained for the test and reference cigarettes, it was concluded that the addition of ingredients did not result in a positive mutagenic response in any of the strains under the conditions already described. Hence, the use of the tested ingredients had no influence on the mutagenic activity of the cigarettes.
Cytotoxicity: The test substance, benzyl propionate did not induce cytotoxicity in an neutral red uptake assay conducted on mouse embryo BALB/c 3T3 cells.

- Details on test system and experimental conditions:
- Three TPM batches and three GVP batches were assayed for each cigarette type. For each batch, four replicate 96-well microtiter plates were used. Each concentration was replicated six times per microtiter plate. In each well, 10(4) cells were seeded and cultivated in culture medium containing 10% fetal bovine serum
(FBS). After 24 h the cells were exposed for 24 h to the smoke fractions dissolved in culture medium containing 4.8% FBS. At the end of the exposure period, the medium containing the smoke fractions was replaced with culture medium containing neutral red (25 mg/ml). Following a 3-h incubation period, 100 ml of an extraction solution (1% acetic acid in 50% ethanol) was added to each well and the absorbance of each well (directly correlated with the number of viable cells) was measured at 540 nm on a microtiter plate reader. To ensure the validity of the assay, TPM from the Reference Cigarette 1R4F and pure acrolein were both assayed in parallel. - Evaluation criteria:
- The cytotoxic response was characterized as the EC50 value; that is, the effective concentration in mg TPM/ml culture medium that reduced the number of viable cells in the exposed culture by 50% compared to the untreated control. The measure of dosing, mg TPM/ml, refers either to the mass of the particulate phase itself or to the trapped gas/vapor phase constituents accompanying that particle mass.
- Statistics:
- Arithmetic means and measures of variance were calculated as descriptive statistics. The one-way analysis of variance was used to compare the results obtained for the control cigarette and those obtained for the test cigarettes containing the same group of ingredients. In those cases where this overall comparison showed a significant difference between the cigarettes, the Duncan test for pairwise comparison was applied. Results were considered to be statistically significant at P40.05 without adjustment for multiple testing

Additional information
Additional information from genetic toxicity in vitro:
Gene mutation: AMES TEST: The test substance, benzyl propionate did not induce mutagenicity in an Ames assay conducted on S. typhimurium TA 1535, TA 1537, TA 98, TA 100 and TA 102 strains with and without S9 activation.

Hence, the use of the tested ingredients had no influence on the mutagenic activity of the cigarettes.
Cytotoxicity: The test substance, benzyl propionate did not induce cytotoxicity in an neutral red uptake assay conducted on mouse embryo BALB/c 3T3 cells.
DNA Damage: Benzyl propionate was not mutagenic to Bacillus subtilis M45 and B. subtilis H17 in the recombination assay at a concentration of 21 µg/disk.
Justification for selection of genetic toxicity endpoint
Data is from a reliable data source having Klimisch rating K2.
Justification for classification or non-classification
The substance, benzyl propionate, is not classified as genotoxic as it gives negative result in the cytotoxicity assay conducted on mouse embryo BALB/c3T3 cells as well as in the bacterial cell recombination assay.Although the Ames test gives positive result for some bacterial strains, it is due to the ingredients already in cigarette smoke and not due to the addition of the test substance. Hence, the substance is concluded to be non genotoxic in nature.
