Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test substance was found to cause erythema or edema (very slight to moderate) 1 hr after removal of the patch. At 24 hrs only very slight reactions were observed in 2 animals and no effects occurred 72 hrs p.a. No classification was derived from the results of this study.
Executive summary:

The test substance was applied to the intact skin of 6 rabbits. The duration of exposure was 4 hours. Occlusive dressings were used. Readings were made 1, 24, 48 and 72 hours after exposure.

The test substance was found to cause erythema or edema (very slight to moderate) 1 hr after removal of the patch. At 24 hrs only very slight reactions were observed in 2 animals and no effects occurred 72 hrs p.a.

No classification was derived from the results of this study.

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

Additional information

Skin irritation/corrosion: Seven studies are available. The results of the studies range in most cases between not irritant and strong irritant, by using different methods. Only 1 study, that of Shapiro 1979, found the substance to be corrosive to the skin. This study and the classification criteria used are not compatible with the OECD-method or EU-classification.

The selected key study is the most recent study, it was performed according to the OECD-method and GLP and was performed to clarify the different results reported earlier.

Eye irritation: Four studies are available. Only one study, the most recent one of Suberg 1985, was performed according to the OECD-method. The other 3 studies give an indication that an eye irritation will occur, when the substance is applied to the eye, but they are not useful for classification purposes.


Justification for selection of skin irritation / corrosion endpoint:
The most recent study according to the OECD-method and GLP is selected. It was performed to clarify the different results ranging from no irritation to corrosion reported previously.

Justification for selection of eye irritation endpoint:
The most recent study and the only one performed according to the OECD-method is selected.

Effects on eye irritation: irritating

Justification for classification or non-classification

Skin irritation/corrosion: No relevant skin irritation was detected in the selected key study.

Eye irritation: Irritations were observed in each of the studies. The key study reports "slight irritation".
