Applicant's summary and conclusion

Interpretation of results:
highly irritating
Remarks:
Migrated information
Conclusions:
Classification: irritating
Surfynol 104 Surfactant is an ocular irritant and possibly corrosive.
Executive summary:

Nine healthy New Zealand White rabbits, free from evidence
of ocular irritation and corneal abnormalities, were dosed. 
Surfynol 104 (0.1 ml) was placed into the conjunctival sac
of one eye of each rabbit.  Six eyes remained unwashed. 
Three eyes were washed with lukewarm water for one minute,
30 seconds postdose.  The eyes were examined and scored by
the Draize technique at one hour and at 24, 48, and 72 hours
postdose.  In order to determine reversibility, the eyes
were examined again on Days 7, 14, and 21.  Sodium
fluorescein was used to determine corneal effects following
the 24-hour scoring interval. There were no abnormal systemic signs noted during the observation period.

Surfvnol 104 Surfactant is an ocular irritant and possiblv corrosive.
