- GLP compliance:
- no
- Remarks:
- pre-GLP
- Test type:
- standard acute method

Test animals
- Species:
- rabbit
- Strain:
- not specified
- Sex:
- not specified
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Weight at study initiation: 2-3 kg
- Housing: Individually housed in metabolism cages
- Diet (e.g. ad libitum): Rabbit pellets, ad libitum
- Water (e.g. ad libitum): Ad libitum
- Acclimation period: At least 2 weeks
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- TEST SITE
- Area of exposure: Prior to placing the animals on test their backs were clipped free of all hair with small animal clippers. The backs were further prepared by making epidermal abrasions every two to three centimeters, longitudinally, over the clipped area of exposure. The abrasions were sufficiently deep so that they penetrated the stratum corneum bot not the dermis, so that no bleeding occurred.
- Type of wrap if used: Application areas were covered with a rubber sleeve or dam which fit snuggly around each animal.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): Application sites were thoroughly wiped down.
- Time after start of exposure: 24 hours
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2.0, 3.9 and 6.0 mL/kg bw - Duration of exposure:
- 24 hours
- Doses:
- 2.0, 3.9 and 6.0 mL/kg bw
- No. of animals per sex per dose:
- 4 rabbits/dose
- Control animals:
- not required
- Details on study design:
- - Duration of observation period following administration: 14 days
- Examinations performed: During the observation period each animal's food consumption, body weights and general behavior were recorded. Before beginning of the test and at the end of the observation period, haematology and urinalysis were performed on all surviving animals.
- Necropsy of survivors performed: No - Statistics:
- None

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The dermal LD50 of the test substance is > 5000 mg/kg bw in rabbits therefore it is not classified according to Regulation (EC) No 1272/2008 and according to the GHS.
- Executive summary:
In an acute dermal toxicity study, 2.0, 3.9 or 6.0 mL/kg bw of the test substance was applied to the clipped intact and abraded skin on the back of 12 albino rabbits (4/dose) for 24 hours. Animals were then observed for dermal reactions, food consumption, body weights and general behaviour for 14 days.
All animals consumed their daily ration, gained weight and behaved as normal laboratory acclimatized animals. Application sites on the back did not show any erythema or oedema and remained normal throughout the study. A comparison of the initial and final haematogram values of each animal did not reveal any significant changes.
Rabbit dermal LD50 > 6 mL/kg bw (equivalent to 5466 mg/kg bw, considering 0.911 g/mL as the density of the test substance).
Therefore, the dermal LD50 of the test substance is > 5000 mg/kg bw in rabbits and it is not classified according to Regulation (EC) No 1272/2008 and according to the GHS.
