Remarks:

GLP, Guideline study: Six rabbits instead of 3 (92/69/EEC B.4) were used since this is a regulatory requirement of EPA-FIFRA. The initial skin reactions were scored 30 minutes after patch removal rather than at 60 minutes. Clinical signs and body weights not reported.

Irritant / corrosive response data:

Three of the 6 test animals showed very slight (grade 1) erythema reactions 30 minutes after patch removal. Very slight erythema persisted in one of these animals until 24 hours, but was not apparent in the other 2 animals at this time. The remaining 3 animals showed no evidence of dermal irritation at any of the observation intervals. Edema and other manifestations of dermal irritation did not occur in any animal at any observation interval (Table 1). Five of the 6 animals had EU index scores of 0.0 and the remaining animal had an index score of 0.33. Consequently, dinotefuran is not classified as irritating to skin according to EU criteria. The PDII for dinotefuran was calculated as 0.2, a score defined as indicating slight irritation according to the EPA classification system.

Table 1: Individual skin irritation and index scores

Animal	Individual erythema / edema scores at:				EPA index	EU index

Total score (erythema + edema)	3	1	0	0	PDII*** 0.2	Mean 0.06

* EPA index score = total erythema & edema score at all observation intervals / no. of observation intervals

** EU index score = total erythema & edema score at the 24, 48 and 72hr intervals / no. of observation intervals

*** PDII = sum of individual index scores / no. of animals, rounded to nearest 0.1

Interpretation of results:

not irritating

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Dinotefuran does not require classification as a skin irritant in the EU according CLP regulation.

Irritant / corrosive response data:

The unwashed eyes of 4 of 6 animals showed slight (grade 1) corneal opacity with epithelial peeling, and iridial irritation in 2 of 6 animals within 24 hours of instillation of dinotefuran (Table 1 and Table 2). The reaction was accompanied by slight to moderate (grade 1 or 2) erythema, chemosis and clear or purulent discharge in all 6 animals. The eyes of 4 of the animals had returned to normal appearance within 96 hours of instillation and the remaining 2 animals had returned to normal 14 days after instillation. A positive reaction occurred in 3 of 3 animals in the washed group and was characterised by slight corneal opacity and slight to moderate erythema, chemosis and discharge. With the exception of one of 3 animals that showed slight erythema and chemosis on day 7, the washed eyes of all animals returned to normal appearance by 96 hours. The appearance of the eyes of the 3rd animal had returned to normal on day 14. The mean irritation scores for all ocular reactions according to Commission Directive 93/21/EEC (Annex VI) were greatest at 24 hours in both the washed and unwashed groups (Table 1). Thereafter, they progressively declined until day 14 at which time all animals in the washed and unwashed eye groups were free of all ocular irritation reactions. None of the individual animal or group mean irritation scores exceeded the EU criteria for classification as “irritating to eyes”.
