Additional information
The key study for acute oral toxicity was conducted according to OECD TG 401 and in compliance with GLP (Hoechst, 1998). The animals showed impairment of motility and respiration as well as narrowed palpebral fissure. Symptoms were reversible after one day. There were no treatment-related body weight changes or mortalities. Narrowed palpebral fissure was reported but there were no macroscopically visible changes at necropsy. The LD50 was determined to be >2000 mg/kg bw.
Justification for selection of acute toxicity – oral endpoint
The study was conducted according to an appropriate guideline and in compliance with GLP.
Justification for classification or non-classification
Based on the available acute oral toxicity study, no classification is required for the registered substance in accordance with Regulation (EC) No. 1272/2008.
