Additional information

The test substance -like aniline- is readily absorbed irrespective the route of administration. Further, the symptoms and effects observed are similar for all routes of administration and identical to those observed after acute exposure to aniline.

Justification for classification or non-classification

Based on the fact that the test substance is toxic irrespective the route of administration it is justified that the current classification includes "acute toxic" for all three routes.
