- Irritant / corrosive response data:
- no corneal or iridial effects were noted during the study- please see attached results in table 1.
minimal conjuctival irritation was noted in both treated eyes one and 24 hours after treatement and persisted in one treated eye at the 48 hour observation, however all signs of redness, chemosis was not present at the 72 hour observation stage. No irreversible effects.
Kay and Calandra classifcation system was used and documented in report, concluding the test item produced a maximum group mean score of 6.0 and was classified as mild irritant ( class4 on a 1-8 scale) to rabbit eye
Group mean score was 6.0 at one hour post treatment, at 24 hours, the groupd mean had reduced to 4.0 and at 48 hours to 1.0 then 0.0 at 72 hours. Individual scores for
Both animals showed expected gain in body weight during the study
Any other information on results incl. tables
The pH of the test item was determined prior to commencement of the study and found to be 9.3 after 10 mins preparation.
Initial pain reaction for both animals was IPR of 2 ( slight initial pain)
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Test item produced weak irritation as judged by modified Kay and Calandra system. Hoever comparison to CLP criteria does not warrant any Irritant classification
