Other effects:
4 hour exposure of abraded skin under occlusive conditions resulted in a combined erythema mean of 0.47 and a combined edema mean of 0.067. Erythema was not fully reversible within 72 hours whereas edema was fully reversible within 48 hours.

24 hour exposure of non-abraded skin under non-occlusive conditions resulted in a combined erythema mean score of 1.0 at 26h and 0.2 at 72h; and a combined edema mean score of 1.0 at 26h and 0 at 72 hours after onset of exposure.

24 hour exposure of intact skin under occlusive conditions resulted in a combined erythema mean of 1.0 and the combined edema mean was 0.75; both the erythema and edema were not fully reversible within 72 hours. 24 hour exposure of abraded skin under occlusive conditions resulted in a combined erythema mean of 1.0 and a combined edema mean of 0.65; both erythema and edema were not fully reversible within 72 hours.

24 hour exposure of intact skin under non-occlusive conditions resulted in a combined erythema mean of 0.6 and the combined edema mean was 0.55; the edema, but not the erythema, was fully reversible within 72 hours. 24 hour exposure of abraded skin under occlusive conditions resulted in a combined erythema mean of 0.85 and a combined edema mean of 0.5; the edema, but not the erythema, was fully reversible within 72 hours.
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The mean erythema and edema scores for the study substance were 0.36 and 0.1 (4 hour occluded), 1.0 and 0.75 (24 hour occluded), and 0.6 and 0.5 (24 hour non-occluded), respectively.This finding does not warrant classification of the study substance as a dermal irritant under the new Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) nor as an R38 skin irritant under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.
Executive summary:

The study substance was administered to the skin of New Zealand White rabbits. Test sites were selected on both the left and right flank of each animals and designated as anterior (4-hour, occluded), middle (24-hour, occluded), and posterior (24-hour, non-occluded). All sites of the right flank were abraded. 0.5 ml of the study substance was applied to each test site. Following the 4 hour exposure, the test sites were evaluated for dermal irritation at 1/2, 24, 48, and 72 hours according to the Draize method. Following the 24 hour exposures, both test sites were evaluated at 26 and 72 hours. Clinical observations were recorded at approximately 1 and 4 hours post-dosing. Slight to moderate erythema and edema were noted at each test site. Soft stool, decreased fecal output, and decreased food consumption were observed in one or more animals. The mean erythema and edema scores for the study substance were 0.36 and 0.1 (4 hour occluded), 1.0 and 0.75 (24 hour occluded), and 0.6 and 0.5 (24 hour non-occluded), respectively.This finding does not warrant classification of the study substance as a dermal irritant under the new Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) nor as an R38 skin irritant under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.

Irritant / corrosive response data:
Mean DRAIZE scores for six animals at 24, 48 and 72 hrs respectively:
Corneal Opacity: 0, 0, 0
Iris Lesion: 0, 0, 0
Conjunctivae: 5.7, 3.3, 1.7
Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The mean corneal opacity, iris lesion, conjunctivae redness, and chemosis scores for the study substance were 0, 0, 0.9, and 0.4, respectively. These findings do not warrant classification of the study substance as an ocular irritant under the new Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) or under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.
Executive summary:

The study substance was administered to one eye of six New Zealand White rabbits to assess for ocular irritation; the other eye was used as a control. Clinical observations were made 1 and 4 hours immediately after treatment and daily thereafter. Ocular damage was assessed and scored according to the Draize method. Mild conjunctival redness and/or swelling were noted in all animals at 24 and/or 48 hours post-dosing. Discharge was noted sporadically throughout the study. The mean corneal opacity, iris lesion, conjunctivae redness, and chemosis scores for the study substance were 0, 0, 0.9, and 0.4, respectively. These findings do not warrant classification of the study substance as an ocular irritant under the new Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) or under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

Skin: The dermal irritation potential of the study substance has been evaluated under occluded conditions. The results indicate negligible dermal irritation.

 

Eye: The ocular irritation potential of the study substance has been evaluated in a manner similar or equivalent to currently established OECD guidelines. The results indicate negligible ocular irritation.

 

Respiratory: The respiratory tract irritation potential of the study substance is not known, as no data are available for this endpoint.

Justification for classification or non-classification

Based on assessment of the available data for the study substance, classification is not warranted as an eye or skin irritant under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP) or under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.


There is no evidence of irritation to the respiratory tract warranting classification.
