Materials and methods

Principles of method if other than guideline:
BASF Test:
Several groups of 5 rats were treated by gavage with suspensions of the test substance in 0.5% Carboxylmethyl cellulose (CMC) aqueous preparation. Group-wise documentation of clinical signs was performed over the 14-day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose. The clinical signs and findings were reported in summary form.
GLP compliance:
no
Test type:
standard acute method
Limit test:
no
