- Number of animals:
- 3 males
- Details on study design:
- TEST SITE
- Area of exposure: On the day of the test a suitable 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.
- Type of wrap if used: Treatment site 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.
REMOVAL OF TEST SUBSTANCE
- Washing: Four hours after application the corset and patches were removed from animals and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water.
- Time after start of exposure: 4 h
SCORING SYSTEM: Draize method

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions the substance is not classified as irritating to skin according to the criteria of CLP Regulation (EC) No. 1272/2008.
- Executive summary:
Test Guidance
OECD guideline 404 and EC Method B.4 (Acute Toxicity: Dermal Irritation / Corrosion).
Method and materials
Three New Zealand White male rabbits were dermally exposed to 0.5 mL of the test material for 4 h under a semi-occlusive dressing. After removal of the residual test item, irritation was scored immediately following removal of the patches and approximately 1, 24, 48 and 72 h later, according to Draize method.
Results
Very slight erythema was noted at two treated skin sites 1 and 24 h after patch removal. No evidence of skin irritation was noted at one treated skin site during the study. All animals showed expected gain in body weight during the study. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0, 0.3, 0.3 for erythema and 0.0, 0.0, 0.0 for oedema score, respectively. The mean erythema and oedema scores at 24, 48 and 72 h were 0.22 and 0.0 respectively. The substance is not a skin irritant in male rabbits.
Conclusion
Under the test conditions the substance is not classified as irritating to skin according to CLP Regulation (EC) No. 1272/2008.
