N: No information about the symbol was reported by the author. In the text, it was mentioned that one animal healed by Day 4, one by Day 9 and one by Day 15 therefore 'N' was considered as equivalent to zero for the calculation of mean scores.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- Under the test conditions, PM 343 Pivaloxycyclene is classified as ‘Irritating to eyes (Category 2)’ according to the CLP Regulation. It is not classified as irritating to eyes according to the Directive 67/548/EEC.
- Executive summary:
In an eye irritation study conducted similarly to the OECD Guideline 405, 0.1 mL of the undiluted test item, PM 343 Pivaloxycyclene, was instilled into one eye of 3 rabbits. The eyes were examined and the changes were scored at 15 min, 4, 24, 48 and 72 h and on Days 5, 8, 9, 10, 11, 12 and 15.
Single application of the undiluted preparation caused moderate corneal opacities, affecting up to all cornea, in all 3 rabbits. These reactions were associated with moderate corneal swelling. All animals had slight to moderate conjunctivitis and 2/3 animals had slight to moderate discharge. One animal healed by Day 4, one by Day 9 and one by Day 15. Mean individual scores at 24, 48 and 72 h for the 3 animals after exposure to undiluted item were 1.0, 0.7, 1.0 for cornea score; 0, 0, 0 for iris score; 1.3, 0.7, 0.7 for conjunctivae score and 0.3, 0.3, 0.3 for chemosis score.
Under the test conditions, PM 343 Pivaloxycyclene is classified as ‘Irritating to eyes (Category 2)’ according to the CLP Regulation.
