Additional information
In the skin irritation test in all 3 animals no signs of skin irritation could be observed. There were no systemic intolerance reactions.
In the eye irritation test all animals showed reddening of the conjunctivae (grade 2), chemosis (grade 1) and lacrimation (grade 1) 1 h after instillation. Only 2 of them had slight irritation signs at the conjunctivae (grade 1) after 24 h. All effects were fully reversible within 2 days. There were no systemic intolerance reactions.
Justification for classification or non-classification
