Additional information
Prediction model based estimation and data from the read across chemicals have been used to determine the toxic nature of the test compound Phenethyl isovalerate (CAS no 140 -26 -1) upon repeated exposure. The summary is as below:
Repeated dose toxicity: Oral
SSS QSAR Prediction model was used to predict the repeated dose oral toxic nature of the test compound Phenethyl isovalerate (CAS no 140 -26 -1). The study was considered to be performed using rats. The test chemical was given orally, daily for 10 -11 days. The No Observed Adverse Effect Level (NOAEL) for the test compound Phenethyl isovalerate is found to be 870 mg/Kg bw/day (nominal.)
A subacute study was conducted (Sustainability Support Services, 2014) to evaluate the toxic effects of repeated administration of Benzyl Propionate (RA CAS no 122-63-4) in male and female Sprague-Dawley rats by gavage. Benzyl Propionate was administered to 6 animals/sex/species in Corn oil at doses of 0,250,500 and 1000 mg/kg/bw/day for 28 days. All rats of 250,500 and 1000 mg/kg/bw/day dose group Survive though-out the study, Benzyl Propionate have no effect on mortality. Blood samples for Clinical Biochemistry and Haematology were collected. No abnormalities occurred that could be directly attributed to Benzyl Propionate treatment. Although significant change in relative weights of liver, ovaries and lungs of female were observed in 1000 mg/kg/bw/day dose groups. No Benzyl Propionate related gross pathological or histological changes were seen and findings were not Benzyl Propionate dependent and hence considered to be of no toxicological importance. Therefore NOEAL for repeated dose toxicity study was considered to be 1000 mg/kg/bw/day in male and female Sprague-Dawley rats when exposed to Benzyl Propionate by oral route for 28 days.
The purpose of this study conducted by Abdo et al (1986) was to evaluate toxicity and carcinogenicity of benzyl acetate (RA CAS no 140-11-4).Benzyl acetate was administered to group of 5 male and femaleF344/N rats for 14 concecutive days by gavage route in corn oil at dose conccentration of 0, 250, 500, 1,000, 2,000 or 4,000 mg/kg body weight. Animals were observed daily for mortalities and clinical signs.Necropsies were performed on all animals.Mortalities were observed in last two groups of rats in first 5 days of treatment. Increase body weight was observed . Hence theNo Observed Adverse Effect Level (NOAEL) was considered to be 500 mg/kg bw/day.
Similar study was performed on mice (Abdo et al, 1986).Benzyl acetate was administered to group of 5 male and female B6C3F1mice for 14 concecutive days by gavage route in corn oil at dose conccentration of 0,125, 250, 500, 1,000, or 2,000mg/kg body weight. Animals were observed daily for mortalities and clinical signs.Necropsies were performed on all animals.Mortalities were observed in last groups of mice within 3 days of treatment.Compound-related clinical signs were observed in high-dose males and females.No stastically significant difference was observed in body weight in treated and control. Hence the No Observed Adverse Effect Level (NOAEL) was considered to be 1000 mg/kg bw/day.
Benzyl butyrate (CAS no 103 -37 -7) was incorporated into the diet of 12 weanling rats of each sex for 12 weeks as part of a blend with five other aromatic esters (Oser, 1985). Average daily intake of 0 or 100 times the assumed human intake, calculated to be 130 mg/kg bw per day. The agents were incorporated into the diet in the ratio of their use in foods: ethyl benzoate, 0.15 mg/kg; isobutyl benzoate, 25 mg/kg: benzyl acetate, 19 mg/kg; benzyl butyrate, 25 mg/kg; ethyl methylphenylglycidate, 25 mg/kg; and glycidate M116, 25 mg/kg. The group receiving the ester blend had normal bodyweight gain, food consumption, efficiency of food use, appearance, and behaviour. The blood haemoglobin and urine glucose concentrations did not differ significantly between test and control groups. Traces of albumin present in urine specimens from both control and test groups were regarded as not significant. At autopsy, no treatmentrelated abnormalities were observed, and the weights of the livers and kidneys were within normal limits for both groups. No histopathological examination was performed .Hence,the NOEL was found to be 25 mg/kg in repeated dose oral toxicity of chemical benzyl butyrate administered to rat for 12 weeks through diet.
Justification for selection of repeated dose toxicity via oral route - systemic effects endpoint:
SSS QSAR Prediction model was used to predict the repeated dose oral toxic nature of the test compound Phenethyl isovalerate. The study was considered to be performed using rats. The test chemical was given orally, daily for 10 -11 days. The No Observed Adverse Effect Level (NOAEL) for the test compound Phenethyl isovalerate is found to be 870 mg/Kg bw/day (nominal.)
Justification for classification or non-classification
Weight of evidence used suggest that the chemical Phenethyl isovalerate (CAS no 140 -26 -1) is not toxic upon repeated oral exposure via the oral route.
