Additional information

In a non-standard skin irritation study, six rabbits each received a single dermal application of 0.5 mL of the test substance (mixed as a 50% gravimetric mineral oil suspension) on two test sites, one abraded and one intact (Cade, 1980). The test substance was covered with a surgical gauze pad and the entire trunk of each animal was encased in an impermeable occlusive wrapping fixed in place with adhesive tape. The wrapping and the test substance were removed 24 h following application. Remaining test substance was gently wiped from the skin, and each test site was individually examined and scored at 24 and 72 h after application for erythema and edema using the Draize skin scoring scale. For all six animals, mean scores from the 24 and 72 h readings were 3 for erythema and 1.7 for edema on intact skin. The irritant effects were not reversible within 72 h. Under the conditions of the test, the test substance was irritating to the skin.

However, the skin irritation study was considered inappropriate and not suitable for classification as the exposure conditions presenting a worst case scenario compared to the current OECD test guideline 404. According to the current OECD 404, the patch with the test substance should be loosely held in contact with the skin by means of a suitable semi-occlusive dressing for the duration of the exposure period, which is normally 4 hours. This is in contrast to the exposure conditions of the available in-vivo skin irritation study of Cade (1980): the exposure period lasted 24 h under occlusive conditions indicating worst case conditions.

Furthermore, the available dermal acute toxicity study in rats indicates no signs of skin irritation at a dermal dose level of 2000 mg/kg bw. In accordance with column 2, 8.1.1 of Annex VIII of the REACH regulation, an in-vivo skin irritation study does not need to be conducted if an acute toxicity study by the dermal route does not indicate skin irritation up to the limit dose level (2000 mg/kg bw). Based on the exposure conditions of the skin irritation study and the outcome of the acute dermal toxicity study (no signs of skin irritation), the in-vivo skin irritation study was disregarded and the result not used for classification. Based on the results of the acute dermal toxicity study, the test substance is not classified as a skin irritant.

Eye irritation was assessed and the test substance was found not to be an ocular irritant to rabbits under the conditions of the test.

Justification for classification or non-classification

The available data on skin and eye irritation/corrosion of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and according to Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
