- Executive summary:
The acute dermal irritation/corrosion of the test item was tested in three albino rabbits.
The test article was applied in a single dose of 0.5 g to a shaved dorsal area of trunk and covered with agauze patch and aluminium foil which was held in contact with the skin by an occlusive dressing. Exposure duration was 4 hours. Thereafter residual substance was removed using water.
Animals were examined for mortality, clinical signs and signs of irritation response 60 minutes, 24, 48, 72 hours after patch removal.
Only a slight erythema was observed one hour after patch removal in two animals. No animal died or showed clinical signs in the course of testing.

- Conclusions:
- The test item is non-irritant to the eye.
- Executive summary:
The acute eye irritation/corrosion of the test item was tested in three albino rabbits. The test article was applied at a single dose of 0.1 g to one of the eyes in each animal. The eyes were washed out 24 hours after instillation of the test article using distilled water. The untreated eye was used for control. The animals were examined for clinical signs and the eyes were examined for lesions of the conjunctivae, cornea and iris 60 minutes, 24, 48 and 72 hoursand from day 4 until day 7 after instillation of the test article.
The instillation of the test article caused a clear redness for 48 hours and a briefly clear swelling of the conjunctivae in all 3 animals.
The cornea was only slight affected and the iris was not affected.
No Signs of systemic effects of the test article were observed in the course of testing.
Reference
In the treated eye a briefly serous lacrimation was observed in all animals one hour after instillation. The control eyes of the animals showed no alterations at any observation time.
The Cornea of the treated eye showed a slight opacity in one animal only one hour after instillation. The iris was not affected.
The conjunctivae of the treated eyes were slightly red in one animal and clearly red in two animals one hour after instillation and clearly red 24 hours after instillation in all three animals. This clear redness continued in all animals until 48 hours after instillation. Then the redness faded in all animals and a redness was not more observed on day 7. One hour after instillation a clear swelling of conjunctivae was observed in two animals and a swelling with lids about half closed was observed in one animal. This swelling faded quickly and 24 hours (in two animals) or 48 hours (in one animal) after instillation a swelling was not more observed. 7 days after instillation no signs of irritation were observed.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not irritating)
Additional information
Based on the available information, the test substance is not irritating to skin, eyes and the respiratory tract. In in vivo-study with albino rabbits no acute dermal irritation/corrosion or eye irritations were detected. Moreover no signs of systemic effects were observed.
The determination of the pH-value of the test substance in a range between 9 and 10, also doesn't contribute to an indication of irritating or corrosive properties.
These findings were supported by an occupational medical assessment. There was no indication of an increase of skin problems caused by exposure to the substance, e.g. corrosive/ irritation effects.
Justification for classification or non-classification
Due to the test results, the test item needs not to be classified irritating/corrosive.
