Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test substance is not an eye irritant according to EU GHS guidelines.
Executive summary:

In cases where no data were available on the target substance, Benzene, C15 -16 -alkyl derivs., data were read across from a structurally related material (the test substance).

This study examined the potential of the test substance to cause eye irritation. 0.1 ml of test substance was placed in one eye of 6 rabbits. The untreated eyes served as controls. The eyes were examined at 1, 24, 48, and 72 hrs, and 7 days after start of exposure for signs of irritation. No signs of irritation were seen in any animal at any observation. The test substance is considered no irritating to eyes.
