- other: the data on historical control rats were used
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were observed frequently during the hours following administration of the test substance, for detection of possible treatment-related clinical signs. Thereafter, observation of the animals was made at least once a day until day 15.
Type, time of onset and duration of clinical signs were recorded for each animal individually. The animals were weighed individually just before administration of the test substance on day 1 and then on days 8 and 15.

After opening the thoracic and abdominal cavities, a macroscopic examination of the main organs (digestive tract, heart, kidneys, liver, lungs, pancreas, spleen and any other organs with obvious abnormalities) was performed. In case of macroscopic lesions, organ samples were taken and preserved in 10% buffered formalin. No microscopic examination was performed.

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the experimental conditions of this study, the dermal LD50 of the test substance Fe3KEDDHSA is higher than 2000 mg/kg in rats.
- Executive summary:
The acute dermal toxicity of the test substance Fe3KEDDHSA was evaluated in rats according to OECD TG 402. The test substance in its original form was applied to the skin of one group of ten Sprague-Dawley rats (five males and five females) at the dose of 2000 mg/kg bw. Purified water was used in order to moisten the test substance and ensure good contact with the skin as well as to remove residual test substance after removal of the dressing. The test site was then covered by a semi-occlusive dressing for 24 hours. Clinical signs, mortality and body weight gain were checked for a period of 14 days following the single application of the test substance. All animals were subjected to necropsy.
No clinical signs and no deaths were observed during the study. A reduced weight gain was seen in 1/5 females between day 1 and day 8. The overall body weight gain of the other animals was similar to that of historical control animals at the test facility. No cutaneous reactions were observed. A slight brownish coloration of the skin which could have masked a possible discrete erythema, was noted in most of the animals on day 2 only. No apparent abnormalities were observed at necropsy in any animal. Under the experimental conditions of this study, the dermal LD50 of the test substance EDDHAS Fe 3K is detremined to be higher than 2000 mg/kg in rats.
