Results and discussion
Any other information on results incl. tables
The negative control responses for opacity and permeability were less than the upper limits of the laboratory historical range indicating that the negative control did not induce irritancy on the corneas. The mean in vitro irritancy score of the positive control (Ethanol) was 55 and was within two standard deviations of the current historical positive control mean. It was therefore concluded that the test conditions were adequate and that the test system functioned properly. LINALOOL OXIDE induced ocular irritation through both endpoints, resulting in a mean in vitro irritancy score of 41 after 10 minutes of treatment.
Since LINALOOL OXIDE induced an IVIS > 3 ≤ 55, no prediction on the classification can be made
Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Eye irritant Cat 2 Criteria used for interpretation of results: EU
- Conclusions:
- Based on the IVIS of 41, the substance is considered an eye irritant.
