- Area of exposure: 2.5x2.5 cm
- Type of wrap: before applilcation, an Elizabeth collar was installed. The test substance (moistened with water) was placed on a patch (lint cloth) and placed on application area. The patch was fixed with a non-woven adhesive bandage and occluded by the adhesive elastic bandage.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): Cleaned with absorbent cotton moisturised with lukewarm water. Then the Elizabeth collar was removed.
- Time after start of exposure: 4 hours
SCORING SYSTEM: According to OECD 404 for erythema and eschar formation and oedema formation. In addition the Primary Irritation Index (PII) was calculated according to Draize.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- E-Y110 had no irritation or corrosion potential on the rabbit skin under the conditions of this study (OECD 404).
- Executive summary:
The acute dermal irritation or corrosion potential of E-Y110 was assessed in three male New Zealand White rabbits according to OECD test guideline 404. The test substance (0.5 g) was moistened with 0.3 ml of water. As a result of the 4 -hour exposure (semi-occluded application) no skin reactions were observed in any animal at any observation time. Therefore, primary irritation index (PII) was 0 and evaluated as not irritating. In conclusion, E-Y110 had no irritation or corrosion potential to the rabbit skin under the conditions of the study.
