- Source
RCC Ltd, Laboratory Animal Services CH-4414 Füllinsdorf / Switzerland
Age when treated
Males: 8 weeks, Females: 12 weeks
Acclimatization
Under laboratory conditions, after health examination. Only animals without any visible signs of illness were used for the study.
Conditions
Standard Laboratory Conditions. Air-conditioned with 10 - 15 air changes per hour, and continuously monitored environment with ranges for room temperature 22 ±3 °C and for relative humidity between 30 - 70 % (values above 70 % during cleaning process possible), automatically controlled light cycle of 12 hours light and 12 hours dark, music during the daytime light period.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- water
- Details on dermal exposure:
- On test day 1, the test item was applied evenly at a dose of 2000 mg/kg body weight on the intact skin with a syringe and covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and fixed with an elastic adhesive bandage.
Application volume/kg body weight: 6 ml - Duration of exposure:
- Twenty-four hours
- Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- not specified
- Details on study design:
- Five male and five female HanRcc:WIST (SPF) rats were treated with the test item at 2000 mg/kg by dermal application. The test item was diluted in vehicle (purified water) at a concentration of 0.33 g/mL and administered at a volume dosage of 6 mL/kg. The application period was 24 hours.
The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2 - 15. Local signs were noted once daily from test day 2 to 15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2 - 15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically. - Statistics:
- No statistical analysis was used.

Applicant's summary and conclusion

- Conclusions:
- LD50 (rat, dermal): greater than 2000 mg/kg body weight
- Executive summary:
Five male and five female HanRcc:WIST (SPF) rats were treated with the test item at 2000 mg/kg by dermal application. The test item was diluted in vehicle (purified water) at a concentration of 0.33 g/mL and administered at a volume dosage of 6 mL/kg. The application period was 24 hours.
The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recorded. All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2 - 15. Local signs were noted once daily from test day 2 to 15. Mortality/viability was recorded at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2 - 15. Body weights were recorded on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically.
No deaths occurred during the study.
No systemic signs of toxicity were observed throughout the whole observation period. Slight black staining of the treated skin area produced by the test item was noted in all animals after removal of the dressing on test day 2 and persisted in one male animal on test day 3. Slight crusts were noted in one female on test day 11 and slight erythema was noted in the same animal on test day 12.
The body weight of the animals was within the range commonly recorded for this strain and age.
No macroscopic findings were observed at necropsy.
The median lethal dose of the test item after single dermal administration to rats of both sexes, observed over a period of 14 days is:
LD50 (rat): greater than 2000 mg/kg body weight and it shall not be classified according to the CLP regulation (Regulation EC No. 1272/2008).
