- Observation period:
- 72 hours
- Number of animals:
- 3 females (1 female subsequently followed by 2 females)
- Details on study design:
- TEST SITE
The test item was applied to a gauze patch and was moistened with aqua ad injectionem.
The patch was then applied to the skin on a small area (approx. 6 cm^2) on the left side of the dorsal area.
The gauze was held in place with non-irritating tape. The patch was fixed with a semi-occlusive dressing.
REMOVAL OF TEST SUBSTANCE
- Washing: yes, using tap water
- Time after start of exposure: 4 hours
OBSERVATIONS
- Clinical signs: approximately 1, 24, 48 and 72 hours after patch removal
- Body Weight: at the start of the study and 72 hours after patch removal
- Irritation: the skin reactions were assessed at approximately 1, 24, 48 and 72 hours after patch removal. The irritation scores and a description of all other (local) effects were recorded.
SCORING SYSTEM
The irritation was assessed according to the numerical scoring system according to OECD 404.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on a skin irritation study with rabbits, performed in accordance with OECD 404 (2002), EU Method B.4 (2008), EPA OPPTS 870.2500 (1998) and according to GLP principles, the substance does not need to be classified for skin irritation.
- Executive summary:
In an in vivo skin irritation study in rabbits, conducted in accordance with OECD 404 (2002), EU Method B.4 (2008), EPA OPPTS 870.2500 (1998) and according to GLP principles, 3 female rabbits were semi-occlusively exposed for 4 hours to 0.5 g of the (moistened) substance. In 2 animals slight redness was observed, which reversed within 24 or within 72 hours. No significant clinical signs of toxicity nor mortalities were observed. Based on the result of this study, the substance does not need to be classified for skin irritation/corrosion in accordance with the CLP Regulation.
