Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test substance produced a primary skin irritation index of 0.0 and was classified as a non-irritant to rabbit skin according to the Draize classification scheme. No corrosive effects were noted.
- Executive summary:
As the test material did not produce positive criteria for irritation or corrosiveness in any rabbit according to the EEC labelling regulations and was classified as non-irritant to rabbit skin. No symbol or risk phrases are therefore required.
