Executive summary:

The test substance was evaluated for acute skin irritation potential in 3 young adult New Zealand white rabbits. A dose of 0.5 g moistened with 0.5 mL water was applied to the intact skin site under a semiocclusive dressing for 4 hours. The application site was then washed and observed for signs of irritation 30 minutes after removal of the test substance, and subsequently on Days 2, 3, and 4. There were no signs of irritation at any time point.

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

Eye irritation

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

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

The test substance did not produce skin irritation in the rabbit; eye irritation in the rabbit was reversible.

Justification for classification or non-classification

The test substance did not produce skin irritation and eye irritation was mild and reversible. The substance does not need to be classified for irritation according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
