Executive summary:

Undiluted test material (0.1 ml) was instilled into the right eyes of six young adult albino rabbits. The test material was not washed from the eyes. Contralateral eyes were used as controls. Eyes were examined at 1, 24, 48, 72 hours and 5 and 7 days and scored (Draize method). The mean primary irritation scores at examinations: 1-hour (1.0/8.0); 24 hours (0.0/8.0); 48 hours (0.0/8.0); 72 hours (0.0/8.0); 5 days (0.0/8.0); and 7 days (0.0/8.0). At 1-hour, all animals exhibited a slight discharge and four of the animals had slight chemosis. No evidence of irritation was noted at any other examination time. The test material was concluded not to be a primary ocular irritant.
