- Irritant / corrosive response data:
- No effects on cornea and iris were observed. Slight redness of the conjunctivae was observed both, after 10 s and after continuous treatment. The effects were obvious after 1 and 6 h. After 10 s treatment, the effects were reversible within 48 h. After continuous treatment, redness reversed within 24 h. In addition, exsudation was observed in both treatment groups, being reversible within 24 h (continuous treatment) and 48 h (10 s treatment), respectively. Chemosis was not observed.
