Additional information

Two "in-vivo" studies are available for each endpoint skin irritation and eye irritation.

Skin irritation

The two studies for skin irritation/corrsosion were performed according EU Test Method B4 and/or OECD Guideline 404. The animals tested where rabbits (New Zealand White, and New Zealand hybrid albino) and were exposed for 4 hours to the substance. Erythema and edema were recorded after 24, 48 and 72 hours after exposure of 500 mg in one of the tests, and after 48 days after exposure of 46 mg in the other test.

Exposure to 500 mg gave a mean score of 0 in each case. Exposure to 46 mg gave erythema score max. 2, but the effects were fully reversible after 3 days.

The results are considered valid for classification and labelling and hazard assessment.

Eye irritation

The two studies for eye irritation were performed according EU Test Method B5 and/or OECD Guideline 405. The animals tested where rabbits (New Zealand White, and New Zealand hybrid albino) treated with 20 mg of substance in one of the tests and with 41 mg in the other test. There were observed a few effects which were fully reversible after 3 days (for test with 41 mg) and after 7 days (for test with 20 mg).

The results are considered valid for classification and labelling and hazard assessment.


Justification for selection of skin irritation / corrosion endpoint:
There are two test results available, with same results.

Justification for selection of eye irritation endpoint:
There are two test results available, with same results.

Justification for classification or non-classification

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. The values obtained have been compared to criteria set up in the Annex I of the Regulation (section 3.2 for skin irritation and section 3.3. for eye irritation). As a result the substance is not considered to be classified as skin irritant under Regulation (EC) No. 1272/2008.

As a result the substance is not considered to be classified as eye irritant under Regulation (EC) No. 1272/2008.
