SCORING SYSTEM: according to the numerical scoring system listed in the Commission Regulation (EC) No 440/2008, B.5.
Data were summarized in tabular form, showing for each individual animal the irritation scores for the designated observation time, a description of the degree and nature of irritation, the presence of serious lesions and non-ocular effects. The scores of each animal at the following reading times (24, 48, 72 hours) were used in calculating the respective mean values (with the exception of the sclerae) for each type of lesion.


TOOL USED TO ASSESS SCORE: Varta Cliptrix diagnostic-lamp (Roth AG, 4153 Reinach / Switzerland)

Irritant / corrosive response data:
The test item did not induce significant or irreversible damage to the rabbit eye.
Other effects:
No staining produced by the test item of the treated eye was observed.
Slight scleral reddening noted in the male and one female at the 1-hour reading. The slight scleral reddening persisted up to the 24- (the male) or
the 48-hour reading (one female).

Any other information on results incl. tables

The instillation of TRIQUAT Monomer into the eye resulted in mild, early-onset and transient ocular changes, such as conjunctival and scleral reddening as well as conjunctival chemosis in the male and one female. The conjunctival effects were no longer evident from 24 hours after treatment. The scleral reddening persisted in both animals at the 24 hours and in one of the two animals at the 48 hours. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed and no clinical signs were observed. One female was devoid of any local signs at any observation time. (see attached table 1)

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based upon the referred classification criteria (Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008 on classification, labeling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and
amending Regulation (EC) No 1907/2006), TRIQUAT Monomer is considered to be “not irritating” to the rabbit eye.
Executive summary:

The primary eye irritation potential of TRIQUAT Monomer was investigated according to OECD test guideline no. 405. The test item was applied by instillation of 0.1 mL into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation.

The instillation of TRIQUAT Monomer into the eye resulted in mild, early-onset and transient ocular changes, such as conjunctival and scleral reddening as well as conjunctival chemosis in the male and one female.The conjunctival effects were no longer evident from 24 hours after treatment. The scleral reddening persisted in both animals at the 24 hours and in one of the two animals at the 48 hours. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed and no clinical signs were observed. One female was devoid of any local signs at any observation time.

Thus, the test item did not induce significant or irreversible damage to the rabbit eye.

The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctival reddening and chemosis were 0.00 for each of the

three animals.
