Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information not classified Criteria used for interpretation of results: EU
- Conclusions:
- The administration of 0.5 g of N-(2-Nitrophenyl)phosphoric triamide to shaved dorsal area of the trunk of albino rabbits did not cause any irritations of the skin. No systemic toxic effects were observed.
- Executive summary:
The acute dermal irritation/corrosion of N-(2-Nitrophenyl)phosphoric triamide was tested in three albino rabbits according to OECD guideline 404. The test item was applied as the original substance at a dose of 0.5g to a shaved dorsal area of trunk and covered with a gauze patch and aluminium foil which was held in contact with the skin with an occlusive dressing. The test was started with one rabbit with exposure periods of three minutes, one hour and four hours. Because no serious skin reaction was observed in this animal the result was confirmed using two further animals with a four-hour exposure.
After each exposure the administration area was cleaned with deionised water.
Animals were examined for mortality, clinical signs and signs of irritation response 60 minutes, 24, 48, 72 hours after patch removal. The grading of skin reaction given in the OECD guideline was used for the evaluation of the dermal irritation.
Not any irritation of the skin at the administration areas was observed. None of the animals died or showed clinical signs during the course of testing.
The administration of 0.5 g of N-(2-Nitrophenyl)phosphoric triamide to shaved dorsal area of the trunk of albino rabbits did not cause any irritations of the skin. No systemic toxic effects were observed.
