- TEST SUBSTANCE PREPARATION
The substance was applied as such.
TEST SITE
Approximately 3 days before treatment, the dorsal fur was clipped with an electric clipper, exposing an area of approximately 100 square centimeters (10x10 cm). The skin of the animals was examined approximately 24 hours before treatment, and, if necessary, regrown fur was again clipped.
APPLICATION
The test substance was applied to approx. 6 square centimeters of the intact skin of the clipped area. It was covered with a 2.5 x 2.5 cm patch of surgical gauze and the gauze was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape.
REMOVAL OF TEST SUBSTANCE
Yes, at the end of the exposure period, using lukewarm tap water.
OBSERVATIONS
- Mortality/Viability: Daily
- Toxicity: Daily
- Body Weight: At start of acclimatization, on the day of application and at termination
- Necropsy: Not applicable
- Irritation:
The skin reactions were assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressings and test substance.
SCORING SYSTEM:
The irritation was assessed according to the numerical scoring system according to OECD 404

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a skin irritation study with rabbits, performed in accordance with OECD 404 (1992) and according to GLP principles, no signs of irritation were observed.
- Executive summary:
In a skin irritation study in rabbits, conducted in accordance with OECD 404 (1992), EU Method B.4 (1992) and according to GLP principles, 1 male and 2 female rabbits were semi-occlusively exposed for 4 hours to 0.5 mL of the substance. No signs of irritation nor clinical signs of toxicity were observed. Based on the results of this study, the substance does not need to be classified for skin irritation/corrosion in accordance with the CLP Regulation.
