Additional information
All animals survived, no clinical signs were observed during the course of the study. Only one animal showed a loss of body weight (0.5%), another animal did not gain body weight from test day 8 to the end of the observation period and for the remaining animals their body weight was within the range commonly recorded for this strain and age.
No significant adversed effect of FAT40812/A via single oral dose of 2000 mg/kg bw in female rat can be concluded.
Justification for selection of acute toxicity – inhalation endpoint
inhalation route of exposure is considered to be unlikely.
Justification for selection of acute toxicity – dermal endpoint
Under the test conditions, slight discoloration was observed from test day 2 to test day 11 (2 males and 3 females) and 13 (3 males and 2 females) but were reversible. Therefore, no significant adverse effect appeared with a single dose of 2000 mg/kg bw of FAT40'8015/A applied on rat's skin.
LD50 (rat) > 2000 mg/kg bw
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
