- Source: Charles River Wiga GmbH, Kißlegg
- Age at study initiation: about 25 weeks
- Weight at study initiation: mean 4.14 kg (range from 3.32 to 4.86 kg)

All animals survived the observation period.

Body weight
Body weight development of the treated rabbits was inconspicuous.
Interpretation of results:
other: EU GHS criteria not met
Conclusions:
The test substance was shown to cause no skin irritation when applied under semiocclusive conditions.
Executive summary:

The skin irritation potential of the registered substance was tested in rabbits according to OECD Guideline 404 and GLP. The test item was mixed with some drops of Aqua pro injectione to ensure good contact to the skin. Afterwards the test material was spread onto patches and applied to the intact skin of three previously shaven rabbits for a 4 hours period under semiocclusive conditions. The first examination of the treated skin sites followed 1 hour after removal of the patches. Then, examinations were performed daily for further 7 days. The test substance was shown to cause no skin irritation.

Additional information

Skin irritation

The skin irritation potential of the registered substance was tested in rabbits according to OECD Guideline 404 and GLP. The test item was mixed with some drops of Aqua pro injectione to ensure good contact to the skin. Afterwards the test material was spread onto patches and applied to the intact skin of three previously shaven rabbits for a 4 hours period under semiocclusive conditions. The first examination of the treated skin sites followed 1 hour after removal of the patches. Then, examinations were performed daily for further 7 days. The test substance was shown to cause no skin irritation.

Eye irritation

The registered substance was tested for eye irritation according to OECD Guideline 405 and GLP. 0.1 g of the test material was applied into the conjunctival sac of rabbits. The first examination of the eyes followed 1 hour after instillation. The examinations were performed daily for further 7 days. No signs of irritation were observed at the cornea and iris. The conjunctivae showed redness (score 1), chemosis (score 1), and discharge (score 2) from day 1 up to day 5 of the study. Later on no signs of irritation were observed. The untreated eyes were unchanged.

Justification for classification or non-classification

Based on the available results no classification for irritation is triggered in accordance with Regulation (EC) No 1272/2008.
