- Executive summary:
Method
The acute toxicity of the test substance was investigated on Wistar rats with an average weight of 150g. The product was administered by stomach tube at 0.5mL/100g body weight, to a group of 10 rats (5 male and 5 female).
Results
Administration of a single dose of 0.5mL/100 g of bodyweight of the product produced no mortality during the10 days following the application of the substance.
Relatively minor symptoms such as drowsiness, accompanied with a slight diarrhea and low piloerection was demonstrated. Any toxic effects disappeared within 24 hours of applying the test substance.
The LD50 of the product is > 5 g/kg body weight (rat) and is therefore regarded as very low toxicity.
