- Irritant / corrosive response data:
- Compound was visible in the eyes up to 24 hours after application, although washing tended to remove some of it.
The eye irritation was generally of a mild nature. A small area of superficial ulceration was seen in one of the rabbits at 24 hours, but this had resolved by 48 hours. - Other effects:

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Compound TK 11339 is slightly irritating to the eyes of New Zealand White rats when tested according to the method used.
- Executive summary:
In a primary eye irritation study, 34/73/5.L, 80 mg of Compound TK 11339 (dioctyltin dichloride) was instilled into the conjunctival sac of the left eye of male and female New Zealand White rabbits and left for 30 seconds before washing. Animals then were observed for 72 hours. Total eye irritation out of 110 was determined.
Compound TK 11339 is slightly irritating to the eyes of New Zealand White rabbits when tested according to the method used.
According to the EU classification system the test material will not be considered irritating to the eye.
