Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: 16 CFR 1500 "Method of testing toxic substances - Acute dermal toxicity (single exposure)"
- Deviations:
- yes
- Remarks:
- Study used less than the recommended number of test animals at each dose level; three male and two female rabbits weighed more than 3000 grams
- Principles of method if other than guideline:
- New Zealand White rabbits, initial body weights 2611 to 3836 g, were used to evaluate the acute dermal toxicity of the test substance. Test animals were caged individually under a 12-hour light/12-hour dark cycle and were acclimated for at least 32 days prior to testing. Food and water were provided ad libitum. Both sexes were initially tested at dose levels of 1000 and 2150 mg/kg; males were then treated with 4640 and 10 000 mg/kg and females were treated with 215 and 464 mg/kg, based on mortality data from the initial doses. Prior to dosing, the trunk of each animal was shaved and the skin of half the animals in each dose group was abraded. The test material was applied undiluted via occlusive patch around the trunk of each animal and wrapped in a layer of gauze and tape. Animals were restrained and observed for signs of systemic toxicity over the 24-hour exposure period. After 24 hours, the patches were removed, the exposed skin was cleaned, and test animals were observed daily for signs of irritation, systemic toxicity and mortality for 14 days. Animals were weighed and necropsied at death; surviving animals were euthanised, weighed and necropsied at the end of the observation period. Mortality data were evaluated by the method of Weil (1952, Biometrics, 8:249-263).

Applicant's summary and conclusion
- Interpretation of results:
- other: Classified as Category 3 in accordance with EU criteria
- Conclusions:
- The acute dermal LD50 value was found to be 2.15 g/kg in male and 1.0 g/kg in female New Zealand White rabbits.
- Executive summary:
The test material was applied undiluted to the skin of sixteen New Zealand White rabbits (two males and two females per dose level) at dosages of 0.215, 0.464, 1.0, 2.15 (females) or 1.0, 2.15, 4.64 and 10.0 g/kg (males) for 24 hours. Animals were observed for gross signs of systemic toxicity, dermal irritation, and death for 14 days. At the end of the 14day observation period, survivors were weighed, killed, and given a gross necropsy.
Deaths occurred between days 3 and 6 of the observation period. Clinical changes associated with the test material included death, shaking behavior, uncoordinated movement, ataxia and hypersensitivity. The most frequently observed irritative effects included erythema, edema, atonia, desquamation and blanching. Gross necropsies performed on the animals that died revealed irritated gastrointestinal tracts, pale or congested kidneys and reddened lungs. Gross necropsies performed on survivors at the end of the study revealed no gross alterations. The acute dermal LD50 value was found to be 2.15 g/kg in male and 1.0 g/kg in female New Zealand White rabbits.
