Results and discussion
In vivo
Results
- Irritation parameter:
- overall irritation score
- Basis:
- mean
- Time point:
- other: 24 and 72 hours
- Score:
- 1.29
- Max. score:
- 8
- Reversibility:
- not specified
- Remarks on result:
- probability of mild irritation
- Irritant / corrosive response data:
- Of the animals demonstrating irritation, most showed barely perceptible to very slight erythema or edema. Only one animal, in the portion of the skin which was abraded, showed clearly defined erythema/eschar formation. The overall average of all animals is an irritation score of 1.29, including scores in abraded skin. Concerning readings in intact skin only, only 2 animals displayed erythema (maximal observed value of 1), and only 1 animal displayed edema (max observed value of 1).

Draize Scoring Criteria:
Primary Skin Irritation Indexes of less than 2.0 are mild irritants.
Primary Skin Irritation Indexes of 2.0 to 5.0 are moderate irritants.
Primary Skin Irritation Indexes of greater than 5.0 are severe irritants.
Erythema was observed in the intact skin and abraded skin of three animals, and only in the abraded skin of three additional animals. Erythema in the intact skin of one animal cleared during the 72 -hour observation period. Edema was observed in the intact and abraded skin of one animal, and in the abraded skin of five additional animals.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- The overall score of 1.29 is below the value of 2.3 or higher in intact skin, as required for classification according to the CLP.
- Conclusions:
- On the basis of the data presented, the substance is mildly irritating to the skin of rabbits. The degree of irritation does not meet the criteria for classification as a skin irritant according to CLP, Regulation EC No. 1272/2008.
