Additional information

Acute oral toxicity

An acute toxicity test was performed to determine the acute toxicity by oral exposure to 3-PPB. The study was conducted in accordance with a relevant test guideline and in compliance with GLP.

A group of three fasted female rats received a single oral gavage dose of the test substance, formulated in corn oil, at a dose level of 2000 mg/kg body weight. As results at this dose level indicated the acute lethal oral dose of the test substance to be greater than 2000 mg/kg body weight, in compliance with the study guidelines, a further group of three fasted females was similarly dosed at 2000 mg/kg body weight to complete the study. There were no deaths during the study. The clinical signs observed during this study were loose faeces in two females dosed at 2000 mg/kg. This sign was first noted approximately 30 minutes after dosing and was not observed from the end of Day 2 onwards. A loss in bodyweight was noted for one rat during the second week of the observation period. All other animals were considered to have achieved satisfactory body weight gains throughout the study. No abnormalities were noted in any animal at the macroscopic examination at study termination on Day 15. Based on these results, the acute median lethal dose (LD50) to rats of 3-Phenylpropyl benzoate was >2000 mg/kg bodyweight

Acute inhalation toxicity

No data available

Acute dermal toxicity

An acute toxicity test was performed to determine the acute toxicity by dermal exposure to 3-PPB. The study was conducted in accordance with a relevant test guideline and in compliance with GLP.

A group of ten rats (five males and five females) received a single topical application of the test substance, as supplied, at a dose level of 2000 mg/kg body weight, for a duration of 24 hours. The animals were retained for a 14 day observation period during which clinical signs, dermal reaction and body weight investigations were performed. There were no deaths and no systemic response to treatment in any animal. Very slight erythema was seen in all females, these reactions had resolved by Day 6. In addition, bandage reactions were seen in all females and two males from Day 2, generally resolving by Day 9 but persisting until termination for one animal. All animals were considered to have achieved satisfactory body weight gains throughout the study. No abnormalities were noted in any animal at the macroscopic examination at study termination on Day 15. Based on these results, the acute median lethal dermal dose (LD50) to rats of 3-Phenylpropyl benzoate was demonstrated to be greater than 2000 mg/kg body weight.

Justification for selection of acute toxicity – oral endpoint
One valid study available.

Justification for selection of acute toxicity – dermal endpoint
One valid study available.

Justification for classification or non-classification

The acute toxicity results for 3 -PPB were reviewed with reference to the EU interpretation of CLP, EU Regulation 1272/2008. On the basis that the available tests confirmed the oral LD50 value to be greater than 2000 mg/kg, and the dermal LD50 value to be greater than 2000 mg/kg bodyweight, 3 -PPB does not require classification as toxic by the oral or dermal exposure.
