Any other information on results incl. tables
Individual skin irritation scores are presented below, All animals appeared active and healthy. Apart from the skin irritation noted below, there were no other signs of gross toxicity, adverse pharmacological effects or abnormal behaviour.
One hour after patch removal, well defined erythema and slight oedema were noted for all three treated sites. The overall incidence and severity of irritation decreased with time. Apart from desquamation noted at all dose sites on Day 7, all animals were free from dermal irritation by study terminatin (Day 7).
The Primary Dermal Irritation Index for Profenofos Technical is 3.1.

Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this study, the test material is classified as moderately irritating to the skin.
- Executive summary:
In a primary dermal irritation study,3 young adult New Zealand rabbits, 2 males and 1 females, were exposed via the dermal route to 0.5 mL of Profenofos Technical/animal. The test material was administered semi occluded as supplied for 4 hours to a clipped area of intact skin measuring ~1 inch2. Animals were then observed for 7 days. Irritation was scored using the Draize scheme.
Under the conditions of this study, the test material is classified as moderately irritating to the skin.
