Additional information

The acute toxicity of the read across substance quinine was tested on rats via oral route. From the study it is shown, that the LD50 is 350.82 mg/kg bw. We conclude that totaquine, which consists of 75% quinine, has a similar LD50 value.

Justification for classification or non-classification

The LD50 of the read across substance quinine of rats after oral application is 350.82 mg/kg bw. According to CLP 1272/2008 criteria for oral application, LD50 > 300 mg/kg bw and < 2000 mg/kg bw, quinine is considered as harmful, if swallowed and has to be classified in category 4. Therefore, we conclude that totaquina, which consists of 75% quinine, is also harmful, if swallowed and has to be classified in category 4, too.
