Endpoint summary
Administrative data
Description of key information
The test substance was found to cause minimal irritation when applied to intact and abraded rabbit skin. The treatment resulted in very slight transient erythema and very slight transient edema. The test item is therefore regarded as non-irritating to the skin. Irritative effects to the eye were partially not reversible.

Additional information
Skin irritation
In the key study the test substance was investigated for skin irritation in rabbits in a test similar to OECD testing guideline 404. The protocol differed by additional testing of abraded skin versus intact skin and a prolonged exposure time of 24h was used. Observation was terminated after 7 days which is acceptable as no indication of erythema or erythema was observed during the observation period. Only minimal erythema and edema reactions well below the threshold of significance were observed. Based on the results of this study, the test article is considered to be not irritating to the rabbit skin. This result is confirmed by additional supporting studies showing the same result.
Eye irritation
An acute eye irritation study following OECD guideline 405 was performed using three New Zealand White Rabbits. An amount of 0.1 g of the test article was placed into the conjunctival sac of the right eye of each animal, the left eye remained untreated and served as the control. The ocular reactions were examined 1, 24, 48, and 72 hours after substance instillation and again during the following observation period by means of a slit-lamp. Under the conditions of the present experiment the test article was found to be irritating and corrosive when applied to the rabbit eye mucosa. All effects were reversible within 21 days except for cornea effects in 2/3 animals, which was still available at scores of 1 and 2, respectively on day 21. In three supporting studies the test substance showed a similar ocular irritation potency.
Justification for classification or non-classification
There are conclusive but not sufficient data for classification of the test item with regard to skin irritation
The test item is not classified for this endpoint in accordance to Directive 67/548/EEC or the CLP Regulation (EC) No 1272/2008 as well as GHS regulations. However, the test substance has to be classified as eye damaging.
