Additional information

Skin irritation

The potential of the test item to cause acute dermal irritation or corrosion was assessed by a single topical application of 0.5 mL of the test substance to the intact skin of 3 white Vienna White rabbits for 4 hours under semiocclusive dressing (BASF SE 1990). The average score (24 to 72 hours) for irritation was calculated to be 0.1 for erythema and 0.0 for edema. The effects were fully reversible within 72 h; thus the study was terminated after 72 hours. Under the test conditions chosen and considering the described findings the test item does not give indication of an irritant property to the skin.

Eye irritation

The potential of the test item to cause damage to the eye was assessed in 3 white New Zealand rabbits, subjected to a single ocular application of 0.1 mL of the test substance (BASF SE 1990). The average score (24 to 72 hours) for irritation was calculated to be 1.0 for corneal opacity, 0.4 for iris, 1.7 for chemosis and 2.0 for conjunctivae redness. Some effects (corneal opacity) were not fully reversible after 21 days. Under the test conditions chosen and considering the described findings, the test item is classified as severely eye damaging.


Justification for selection of skin irritation / corrosion endpoint:
Key study was selected for selection, study is similar to guideline study.

Justification for selection of eye irritation endpoint:
Key study was selected for selection, study is similar to guideline study.

Effects on eye irritation: corrosive

Justification for classification or non-classification

Based on the results, classification for skin irritation is not warranted according to the criteria of EU Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No 1272/2008.

Based on the results of the in vivo eye irritation study, the test substance is classified as Xi, R41 (risk of serious damage to eyes) according to the criteria of EU Directive 67/548/EEC and as eye damage cat. 1, H318 (Causes serious eye damage) according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No 1272/2008.
