Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of the test the substance is considered to be not corrosive or irritating to the skin.
- Executive summary:
The potential to cause acute dermal irritation or corrosion was assessed in a OECD 404 guideline study (in compliance with GLP) by a single topical application of 0.5 mL of the test substance to the intact skin of 3 white Vienna rabbits for 4 hours under semiocclusive dressing. The average score (24 to 72 hours) for irritation was calculated to be 0.1 for erythema and 0.0 for edema. The findings were reversible between 24 and 48 hours after removal of the patches. It was concluded that the test substance was not irritating to the skin.
