Additional information
In a key study the undiluted substance was applied to New Zealand white rabbits under semi-occlusive dressing for four hours. Application sites were evaluated in accordance with the method of Draize at approximately 30-60 minutes following patch removal, were also made after 24, 48 and 72 hours and on days 7 and 14. In this study, slight irritation was seen which resolved within 14 days of exposure. The primary irritation index was calculated to be 1.7 for sites treated with the test material.

The test material produced mild to moderate conjunctival irritation in the albino rabbit eyes which fully reversed in all animals by Day 14. Corneal involvement was observed in 5/6 animals however it was not evident at day 7. No iritis was noted during the 14 day observation period.
