Key value for chemical safety assessment

Acute toxicity: via oral route

Endpoint conclusion
Dose descriptor:
2 500 mg/kg bw

Additional information

In a valid oral toxicity study the approximative LD50 was 3100 to 5000 mg/kg bw for male rats and 2500 mg/kg bw for female rats.

Justification for classification or non-classification

In male and female rats a LD50 > 2000 mg/kg bw was found in male and female rats. Therefore a classification is not justided.
