Materials and methods
Test guideline

- no guideline followed
- Principles of method if other than guideline:
- Four normal, healthy, albino rabbits, weighing 2 to 3. 5 kilo, were used in this study. The animals had been acclimated to laboratory conditions for at least two weeks prior to being placed on test. 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 depp so that they penetrated the stratum corneum but not the dermis, so that no bleeding occurred.
The test material, at a level of 5 ml. per kilo, was applied to the clipped intact and abraded skin areas. These areas were covered with a rubber sleeve or dam which fit snuggly around each animal. The animals were then placed in a multiple animal holder and held there for a twenty-four hour period. During this time each test animal was allowed its daily ration of rabbit pellets and water. - GLP compliance:
- no
- Test type:
- standard acute method

- rabbit
- Strain:
- other: Albino
- Sex:
- not specified

- Four normal, healthy, albino rabbits, weighing 2 to 3. 5 kilo, were used in this study. The animals had been acclimated to laboratory conditions for at least two weeks prior to being placed on test.
Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- unchanged (no vehicle)
- Duration of exposure:
- 24
- Doses:
- 5 mL/kg bw
- No. of animals per sex per dose:
- 3
- Control animals:
- no
- Details on study design:

Results and discussion
Effect levels
- Sex:
- not specified
- Dose descriptor:
- LD50
- Effect level:
- > 5 mL/kg bw
- Based on:
- test mat.
- Remarks on result:
- not determinable due to absence of adverse toxic effects
- Mortality:
- No deaths occurred at a level of 5 ml. per kilo.
- Clinical signs:
- All the animals showed a mild erythema on both the intact and abraded areas.
- Body weight:
- The dosing caused no adverse effects.
- Gross pathology:
- not further specified
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The LD50 was greater as 5 mL/kg bw.
- Executive summary:
The single dermal dosing of rabbits with 5 mL/kg bw of the test item caused no mortality or any visible toxic effects, except of mild erythema. As this dose level did not produce a toxic effect, a complete LD50 study was not performed.
