- Conclusions:
- The test item did not reveal any remarkable irritation potential on the skin of rabbits, tested in this study according to OECD test guideline no. 404 and GLP conditions.
- Executive summary:
The primary skin irritation potential of the test item was investigated according to OECD test guideline no 404.The test item (0.5 g moistened with 0.5 ml purified water) was applied to the intact skin of three New Zealand White rabbits under semi-occlusive conditions for four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours as well as 7 and 10 days after removal of the test item.
No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred. A light yellow staining was produced by the test item on the treated skin of the three rabbits. This persisted up to the 48-hour reading or up to day 7. A very slight erythema was noted in two animals at the 1-hour reading but was no longer present on the following day. Therefore, all scores are 0.

- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test item did not reveal any remarkable irritation potential on the eyes of rabbits, tested in this study according to OECD test guideline no. 405 and GLP conditions.
- Executive summary:
The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation. The instillation of the test item into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae. These effects were reversible and were no longer evident 72 houres after treatment, the end of the observation period for all animals. In two animals a slight corneal opacity affecting the whole area was noted at the 1-hour reading but was no longer present on the following day.
The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 0.67, 0.67 and 0.33 for reddening and 0.00 for chemosis for all animals, respectively.
No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed and no clinical signs were observed.
