- Irritant / corrosive response data:
- Individual skin irritation scores are presented. A summary of primary skin irritation scores used for calculation of Primary Dermal Irritation Index is presented. Within 24 hours of patch removal, all three treated sites exhibited severe erythema and very slight edema. Desquamation was noted for two animals between Days 10 and 14. Although the overall severity of irritation decreased gradually by the end of the study, irritation persisted for all animals through Day 14 (study termination).
- Other effects:
- All animals appeared active and healthy. Apart from the dermal irritation, there were no other signs of gross toxicity, adverse pharmacologic effects or abnormal behavior.
- Interpretation of results:

- Remarks:
- Migrated information Criteria used for interpretation of results: US EPA pesticides
- Conclusions:
- Under the conditions of the study the test substance is considered to be moderately irritating to skin.
- Executive summary:
The study was performed to US EPA OPPTS 870.2500 and OECD 405 to assess the primary skin irritancy potential of the test substance in accordance with GLP. Five-tenths of a milliliter of the test substance was applied to one 6 cm2 intact dose site on each animal and covered with a 1 inch x 1 inch, 4-ply gauze pad. The pad and entire trunk of each animal were then wrapped with semi-occlusive 3 inch Micropore tape to avoid dislocation of the pad. After 4 hours of exposure to the test substance, the pads and collars were removed and the test sites were gently cleaned of any residual test substance. Individual dose sites were scored according to the Draize scoring system at approximately 1, 24, 48, and 72 hours and at 7, 10, and 14 days after patch removal. The classification of irritancy was obtained by adding the average erythema and edema scores for the 1, 24, 48, and 72-hour scoring intervals and dividing by the number of evaluation intervals. Within 24 hours of patch removal, all three treated sites exhibited severe erythema and very slight edema. Desquamation was noted for two animals between Days 10 and 14. Although the overall severity of irritation decreased gradually by the end of the study, irritation persisted for all animals through Day 14 (study termination). The Primary Dermal Irritation Index for the test substance is 4.5. Under the conditions of this study the substance is classified as moderately irritating to the skin.

Skin irritation:

Although the overall severity of irritation decreased gradually by the end of the study, irritation persisted for all animals through Day 14 (study termination). The Primary Dermal Irritation Index for the test substance is 4.5. Under the conditions of this study the substance is classified as moderately irritating to the skin.
Eye irritation:
The study was performed according to US EPA OPPTS 870.2400 and OECD 405 acute eye irritation in vivo and in accordance with GLP. A volume of 0.1 ml of the test material was placed into the conjunctival sac of one eye of 3 animals. The other eye remained untreated and was used for control purposes. Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment. There was no corneal opacity or iritis observed during this study. One hour after test substance instillation, all three treated eyes exhibited conjunctivitis. The overall incidence and severity of irritation decreased with time. All animals were free of ocular irritation by 72 hours. All animals appeared active and healthy. There were no other signs of gross toxicity, adverse pharmacologic effects or abnormal behaviour. Under the conditions of this study the test material is mildly irritating.
The applicant’s re-calculation of the mean scores following grading at 24, 48 and 72h and the individual scores which were fully reversible within 72 hours, the test material is not considered to be irritating to the eye under Regulation (EC) 1272/2008 criteria.
Justification for selection of skin irritation / corrosion endpoint:

Justification for selection of eye irritation endpoint:
