- Irritant / corrosive response data:
- The primary irritation index of test article was 0.14 (taking into account the 4 hour-reading with a score of 1 in 1/6 animals). The test article is therefore regarded as mild irritant, not requiring any classification. The structure of the tissue at the contact site was not destroyed within 24 hours of application in any of the 6 animals and the test article is therefore considered non-corrosive, too.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test item was found to be non-irritating to rabbit skin.
- Executive summary:
A study was performed to determine the primary skin irritation index and corrosive effects of the test item in the New Zealand White rabbit. The study design was based on OECD Guidelines No. 404. Six female rabbits were tested and 0.5 ml test substance applied undiluted onto the clipped skin area of the animals. A single 4 -hour application produced a primary irritation index of 0.14. The test item was classified as a non-irritant to rabbit skin. No corrosive effects were noted.
