Results and discussion

Any other information on results incl. tables

The US FDA scoring scale was used to assess cornea opacity, iris integrity and conjunctivae redness and chemosis.

All the scores were zero after 24 and 48 hours except in one animal that had a redness score of 1 on a Draize scale of 0 to 4 at 24 hours.

Applicant's summary and conclusion

Conclusions:
The substance (3-chloro-2-hydroxypropyl)trimethylammonium chloride is not irritating to the rabbit eye.
Executive summary:

The eye irritation potential of (3 -chloro-2 -hydroxypropyl)trimethylammonium chloride was assessed using six New Zealand White rabbits. The test substance (0.1 ml, 55% solution in water) was applied to one eye of each rabbit. The other eye remained untreated and served as a control. The eyes were not washed and were examined at 24, 48, 72 hours and 7 days after the instillation of the test substance. The US FDA scoring scale was used to assess cornea opacity, iris integrity and conjunctivae redness and chemosis.

All the scores were zero after 24 and 48 hours except in one animal that had a redness score of 1 on a Draize scale of 0 to 4 at 24 hours. The substance (3-chloro-2-hydroxypropyl)trimethylammonium chloride is not irritating to the rabbit eye.
