Additional information
Oral Toxicity
In the key study (Levenstein, 1972) the acute toxicity of the test material was determined in a limit test performed at 5000 mg/kg (5 mL/kg). The study was performed to sound scientific principles with limited but a sufficient level of reporting to assess the quality of the submitted data. The method followed was similar to the current standardised guideline OECD 402 with deviations not thought to affect the validity of the results presented. Four rabbits were exposed to the test material under an occlusive dressing for 24 hours. Animals were exposed on the back of each animal to intact and abraded. Abraded skin was prepared by making epidermal abrasions every 2 -3 cm, longitudinally, over the clipped area. Post exposure the dressing was removed, the dermal reaction scored and the site thoroughly wiped to remove any remaining test material. Animals were then returned to their cages and observations continued for 14 days. Under the conditions of the test, no mortality was observed in the limit test. All animals showed a moderate erythema after 24 hour exposure, similar reactions observed on both the intact and abraded skin.
Dermal Toxicity
The acute dermal toxicity of the test material has been assessed by read-across to structural, mechanistically similar substance using the OECD QSAR Toolbox to predict the dermal LD50 of 3030 mg/kg. QSAR predicting is attached within the endpoint.
Predicted LD50 in rabbits after dermal application is 3030 (1790 - 5150) mg/kg.
Inhalation Toxicity
In line with Column 2, point 8.5.2, Annex VIII of Regulation 1907/2006, an acute inhalation study does not need to be performed as the substance has a low vapour pressure and the use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur. The acute toxicity endpoint has been addressed by assessing the toxicity via the oral and dermal routes, which is more appropriate when considering the properties of this substance.
Justification for classification or non-classification
According to the criteria outlined in Regulation 1272/2008 and Directive 67/548/EEC, the test material does not meet the criteria for classification for acute toxicity.
