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 New Zealand rabbits for 4 hours under semi-occlusive dressing (GLP-guideline study; MB Research Laboratories, 2007). The average score (24 to 72 hours) for irritation was calculated to be 0.0 for erythema and 0.0 for edema. No skin findings were induced by the test item; 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.


These findings are confirmed by a supporting study with less reliability showing an irritation score of 2/10 indicating only very slight irritation not subject to classification (Smyth, 1962).


 


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 (GLP-guideline study; MB Research Laboratories, 2007). The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, iris and chemosis and conjunctivae redness. 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 eye.


These findings are confirmed by a supporting study with less reliability showing an irritation score of 1/10 indicating only very slight irritation not subject to classification (Smyth, 1962).

Justification for classification or non-classification

Classification 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.
