Additional information
Prediction model based estimation and data from the read across chemicals have been used to determine the mutagenic nature of the test compound Phenethyl isovalerate (CAS no 140 -26 -1). The summary is as below:
Gene mutation in vitro:
Gene mutation was predicted using SSS QSAR prediction model, 2016. The study used Salmonella typhimurium TA97 and TA102 strain and S9 metabolic activation system. The test material Phenethyl isovalerate is not mutagenic in vitro in Salmonella typhimurium strain TA 97 and TA 102 with and without S9 metabolic activation system.
Gene mutation was predicted using SSS QSAR prediction model, 2016. The study used Salmonella typhimuriumTA1535, TA1537, TA98 and TA100 strain and S9 metabolic activation system. The test material Phenethyl isovalerate is not mutagenic in vitro in Salmonella typhimurium strain TA 97 and TA 102 with and without S9 metabolic activation system.
Based on the QSAR prediction done using the Danish (Q)SAR Database (2016), the genetic toxicity was estimated to be negative during Ames test in S. typhimurium TA 1535, TA 1537, TA 98 and TA 100. Thus it can be concluded that the substance Phenethyl isovalerate is non mutagenic and based on the CLP criteria for classification it can be not classified for genetic toxicity.
Genetox study for Isoamyl phenylacetate (RA CAS no 102 -19 -2) in Bacillus subtilis strain H17(rec+) and M45 (rec-) by Rec assay was conducted at the concentration of 20 μg/disk. At this concentration the result of Rec assay in Bacillus. Subtilis strainH17(rec+) and M45 (rec-) was found to be negative (Adams et al, 2005).
The mutagenicity of total particulate matter (TPM) in study 1 cigarettes was investigated (Renne et al, 2006) using an Ames assay protocol that conformed to OECD Guideline 471. For this purpose, prototype cigarettes containing a mixture of ingredients, reference cigarettes without these ingredients, and 2R4F cigarettes (a standard reference cigarette). The concentration of benzyl phenylacetate (RA CAS no 102 -16 -2) in the study 1 is 0.0026mg/lt. Each sample was tested with and without S9 metabolic activation in five strains of Salmonella typhimurium: TA98, TA100, TA102, TA1535, and TA1537.Evaluation of the Ames assay data was carried out in terms of the mutagenic response, taking into consideration the reproducibly dose-related increase in number of revertants, even if the increase was less than twofold. The results of Ames assays on test cigarettes from study 1 with and without metabolic activation. TA100, TA98, and TA1537 strains spohowed a positive response only with metabolic activation. No response was observed in TA 102 or TA1535. No sporadic responses in revertants were recorded. The highest sensitivity and specificity of the mutagenic response were observed using TA98 with metabolic 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. Isoamyl phenylacetate can be considered to be non mutagenic at a test concentration of 0.0065mg/l under the test conditions.
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 (Renne et al, 2006).
The test substance, benzyl propionate (RA CAS no 122 -63 -4) 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 rat liver S9 activation. Although positive response is observed in some strains, there were also no apparent trends discernible that would suggest a change in mutagenic activity caused by the addition of the ingredients (Roomer et al, 2002).
As per the CLP classification and the weight of evidence used, the test material Phenethyl isovalerate (CAS no 140 -26 -1) is not likely to be a gene mutagen in vitro.
Justification for selection of genetic toxicity endpoint
Gene mutation was predicted using SSS QSAR prediction model, 2016. The study used Salmonella typhimurium TA97 and TA102 strain and S9 metabolic activation system. The test material Phenethyl isovalerate is not mutagenic in vitro in Salmonella typhimurium strain TA 97 and TA 102 with and without S9 metabolic activation system.
Justification for classification or non-classification
As per the CLP classification and the weight of evidence used, the test material Phenethyl isovalerate (CAS no 140 -26 -1) is not likely to be mutagenic in vitro.
