Additional criteria in Directive 93/21/EEC Point 3.2.6.2 fulfilled: Yes
All animals appeared active and healthy during the study apart from the eye irritation noted, there were no other signs of gross toxicity, adverse pharmacologic effects or abnormal behaviour.
No corneal opacity or iritis was noted for any treated eye during the study. One hour after test material instillation conjunctivitis was noted for all three treated eyes. The overall incidence and severity of irritation decreased with time. All animals were free of ocular irritation within 72 hours.
The maximum mean total score of Profenofos Technical was 12.0
Applicant's summary and conclusion
- Conclusions:
- Based on the results of this study, Profenofos Technical is classified as mildly irritating to the eye.
- Executive summary:
In a primary eye irritation study, 0.1 mL Profenofos Technical (undiluted) was instilled into the conjunctival sac of the right eye of three young adult New Zealand White rabbits. The left eye acted as a control. Animals were then observed for 3 days. Irritation was scored using the Draize scheme for unwashed eyes, with the system of Kay and Calandra used to classify the test material.
All animals appeared active and healthy during the study apart from the eye irritation noted, there were no other signs of gross toxicity, adverse pharmacologic effects or abnormal behaviour.
No corneal opacity or iritis was noted for any treated eye during the study. One hour after test material instillation conjunctivitis was noted for all three treated eyes. The overall incidence and severity of irritation decreased with time. All animals were free of ocular irritation within 72 hour
Based on the results of this study, Profenofos Technical is classified as mildly irritating to the eye.
