Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- The test material, GR91287X, produced a primary irritation index of 0.0 and was classified as non-irritant to rabbit skin according to the Draize grading scheme. No corrosive effects were noted.
- Executive summary:
GR91287X did not meet the criteria necessary for classification as irritant or corrosive to skin. according to EC labelling regulations. No symbol or risk phrase are required.
