Executive summary:

A skin irritation test was performed according to OECD 404 and GLP. In the study 5 rabbits were exposed to 0.5 mL of the undiluted test substance for 4 hours. After removal of the test substance the test site (2.5 x 2.5 cm) was evaluated after 1, 24, 48, 72 hours and 7 days. The mean erythema and edema score for 24/48/72h and 7 days were 0. Due to these results the test substance was found to be not skin irritating and without classification at 100 %.

Executive summary:

The potential of the test substance to cause eye irritation was tested in five rabbits according to OEDC 404 and GLP. The animals were treated with 0.1 mL test substance and observed for 7 days. The mean score for cornea opacity and iris were 0 for 24/48/72 h. Till 8 hours post application slight to clear conjunctival irritations could be observed with slightly increased redness, chemosis and slightly increased secretion. The conjunctivae score was 0 for 24/48/72 h. All effects observed were reversible within 24 h. Due to these results the test substance was found to be not irritating for the eye.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

The available experimental test data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on skin irritation/corrosion, the test item is not classified according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.

Based on available data on eye irritation/corrosion, the test item is not classified according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
