The dosage level was 0.5 ml/site and an adjacent area of untreated skin served as the control site. - Duration of treatment / exposure:
- On the day of the test a suitable test site was selected on the back of each rabbit. A quantity of 0.5 mL of the test item was applied directly to the skin under a 2.5 cm x 2.5 cm cotton gauze patch. The patch was secured in position with a strip of surgical adhesive tape. To prevent the animals interfering with the patches, the trunk of each rabbit was wrapped in an elasticated corset and the animals were returned to their cages for the duration of the exposure period. Four hours after application the corset and patches were removed from each animal and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water.
- Observation period:
- Immediately following removal of the patches and approximately 1, 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation.
- Number of animals:
- 2 rabbits (The number of animals used was the minimum required to achieve the objectives of the study. Testing was conducted in two animals and the response in those animals was such that exposure of a third animal would not affect classification of the test item, no further testing was needed.)
- Details on study design:
- On the day before the test two rabbits were clipped free of fur from the dorsal/flank area using veterinary clippers. Only animals with a healthy intact epidermis by gross observation were selected for the study. On the day of the test a suitable test site was selected on the back of each rabbit. A quantity of 0.5 mL of the test item was applied directly to the skin under a 2.5 cm x 2.5 cm cotton gauze patch. The patch was secured in position with a strip of surgical adhesive tape. To prevent the animals interfering with the patches, the trunk of each rabbit was wrapped in an elasticated corset and the animals were returned to their cages for the duration of the exposure period. Four hours after application the corset and patches were removed from each animal and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water. Immediately following removal of the patches and approximately 1, 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation and scored according to the following scale:
EVALUATION OF SKIN REACTIONS
Erythema and Eschar Formation
No erythema 0
Very slight erythema (barely perceptible) 1
Well-defined erythema 2
Moderate to severe erythema 3
Severe erythema (beef redness) to eschar formation preventing grading of erythema 4
Edema Formation
No edema 0
Very slight edema (barely perceptible) 1
Slight edema (edges of area well-defined by definite raising) 2
Moderate edema (raised approximately 1 millimeter) 3
Severe edema (raised more than 1 millimeter and extending beyond the area of exposure) 4
Any other skin reactions and clinical signs of toxicity, if present, were also recorded.
An additional observation was made on Day 7 to assess the reversibility of skin reactions.
Individual body weights were recorded on Day 0 (the day of dosing) and at the end of the observation period.

Very slight erythema and very slight edema were noted at both treated skin sites one hour after patch removal with well-defined erythema and very slight or slight edema noted at the 24 and 48-Hour observations. Well-defined erythema and slight edema were noted at one treated skin site with very slight erythema and very slight edema noted at the other treated skin site at the 72-Hour observation. Loss of skin elasticity was also noted at both treated skin sites at the 72-Hour observation.
The dermal reactions were completely reversible, starting on Day 3, and both treated skin sites appeared normal at the 7-Day observation. - Other effects:
- Loss of skin elasticity at 72 hours in both animals. Effect reversed within 7-day observation period.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The substance is not a skin irritant in rabbits.
In accordance with EU CLP Regulation (EC) No. 1272/2008 classification of this substance is not required for dermal irritation because scores for erythema and edema did not fulfill the criteria for classification. In addition the primary effects, erythema and edema, were fully reversible by the end of the 7-day observation period. - Executive summary:
Test Guidance
OECD Guideline No. 404 and EU Method B4
Introduction
The study was performed to assess the irritancy potential of the test item to the skin of the New Zealand White rabbit.
Method and materials
On the day before the test two rabbits were clipped free of fur from the dorsal/flank area using veterinary clippers. Only animals with a healthy intact epidermis by gross observation were selected for the study. On the day of the test a suitable test site was selected on the back of each rabbit. A quantity of 0.5 mL of the test item was applied directly to the skin under a 2.5 cm x 2.5 cm cotton gauze patch. The patch was secured in position with a strip of surgical adhesive tape. To prevent the animals interfering with the patches, the trunk of each rabbit was wrapped in an elasticated corset and the animals were returned to their cages for the duration of the exposure period. Four hours after application the corset and patches were removed from each animal and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water. Immediately following removal of the patches and approximately 1, 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation and scored according to the Draize scheme.
Results
A single 4-Hour, semi-occluded application of the test item to the intact skin of two rabbits produced well-defined erythema, very slight or slight edema and loss of skin elasticity. The dermal reactions were completely reversible, starting on Day 3, and both treated skin sites appeared normal at the 7-Day observation.
Conclusion
The test item produced a primary irritation index of 3.3. No corrosive effects were noted.
In accordance with EU CLP Regulation (EC) No. 1272/2008 classification of this substance is not required for dermal irritation because scores for erythema and edema did not fulfill the criteria for classification. In addition the primary effects, erythema and edema, were fully reversible by the end of the 7-day observation period.
