Clinical signs:
Signs of toxicity related to dose levels:There were no deaths. Signs of reaction to treatment observed in all rats within three hours of dosing were piloerection, increased salivation, abnormal body carriage (hunched posture), abnormal gait (waddling) and diarrhoea. Complete recovery was reached 2 days after treatment.

Additional information

Justification for selection of acute toxicity – oral endpoint
Data has been provided by ECHA from a previous notification. The data has been reviewed by a suitable Competent Authority and adjudged to be suitable for registration.

Justification for classification or non-classification

The substance is not classified under CLP as it does not fill the requirements for classification.
