Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- EU criteria not met
- Conclusions:
- Under the conditions of this study the test substance cannot be considered as an eye irritant.
- Executive summary:
The pre-GLP study was completed under 16 CFR 1500.42 following a guideline similar to OECD 405, to assess the irritancy potential of the test material to the eye following a single application in the New Zealand White rabbit. A volume of 0.1 ml of the test material was placed into the conjunctival sac of one eye of 6 animals. The other eye remained untreated and was used for control purposes. Assessment of ocular damage/irritation was made approximately 24, 48 and 72 hours following treatment. No corneal opacity or iridal irritation was observed on any day. Very slight irritation redness and chemosis; max score 1; fully reversed within 72 hours. Based on the applicants recalculation of the mean scores the test material is not considered to be irritating to the eye under Regulation (EC) 1272/2008 criteria due to a complete absence of Corenal Opacity and Corneal Iritis indicative of full reversibility within 21-days. Redness and Chemosis scores were minor and fully reversed within 72 hours. There was additionally an absence of significant variation of responses.
