Executive summary:

500 mg of the test substance was semi-occlusively applied to the shaved intact skin of 3 female rabbits for an exposure period of 4 h. Evaluation of skin irritation was made according to Draize.

In this skin irritation study N-Formylaminosorbit was not irritating to the skin.

Executive summary:

100 mg of the test substance was administered into the conjunctival sac of one eye of female rabbits with rinsing 24 h after instillation.

Evaluation of eye irritation was made according to Draize.

According to the classification criteria N-Formylaminosorbit is not irritating to eyes.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

In the skin irritation test in all 3 animals no signs of skin irritation could be observed.

In the eye irritation test discharge (grade 1) 1 h after instillation was the only finding in all 3 animals. No signs of eye irritation could be observed after 24, 48 and 72 h.


Justification for selection of skin irritation / corrosion endpoint:
only one study available

Justification for selection of eye irritation endpoint:
only one study available

Justification for classification or non-classification

Based on the study results a classification according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 (CLP) is not required.
