Directly before the administration the test material was prepared with aqueous Methocel K4M Premium solution as vehicle. This study was performed according to the ,,Acute toxic class method" (ATC; OECD TG 423). No signs of toxicity were detected in the 3 male and 3 female rats after treatment and no rat died. The gross pathological examination revealed no organ alterations. According to the results of this study the test material can be allocated to ATC class 0 i.e. the LD50 value is expected to exceed 2000 mg/kg.

It was difficult to distinguish between slight clinical findings and reactions due to fixation by the tape. The behavior and general condition of all rats were monitored for at least 6 hours after administration and then checked daily.
