Test animals

Species:
rabbit
Strain:
other: New zealand variety
Sex:
not specified
Details on test animals or test system and environmental conditions:
Ten mature albino rabbits of the New Zealand variety were selected from the stock colony for this study.

Administration / exposure

Type of coverage:
semiocclusive
Vehicle:
unchanged (no vehicle)
Details on dermal exposure:
The test article was applied at 2g/kg to the clipped skin of five intact and five abraded rabbits. The rabbits were wrapped with a dam. After 24 hours, the wrapping was removed and the residue gently washed off.
Duration of exposure:
24hours
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
10
Control animals:
not specified
Details on study design:
The test site was examined for erythema and edema and scores were recorded daily for 14 days. Bodyweights were recorded on days 0, 3, 7, 10 and 14. A gross examination of the viscera was conducted on all rabbits sacrificed at 14 days.
Statistics:
no data

Results and discussion

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Remarks on result:
other: no adverse effect was observed at level of 2000 mg/kg.
Mortality:
One animal died on day 10.
Clinical signs:
No erythema or edema were noted during the 14-day observation period. The general appearance of the rabbits remained good throughout.
Body weight:
Bodyweight gain was acceptable for all rabbits during the 14-day study.
Gross pathology:
No gross pathology was noted in the rabbits sacrificed at 14 days.
Other findings:
no data

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based on the results of this study, test article would be considered dermally non-toxic.
Executive summary:

This study was conducted to evaluate the dermal toxicity of tes article in the rabbit accoring to the Federal Hazardous Substances Act. The paste was applied at 2000 mg/kg of body weight to the intact and abraded skin. One animal died on day 10 which is believed not compound related. No dermal reactions were observed. Body weight gain and general appearance of the rabbits remained good throughout the 14 -day observation period.

Therefore, test substance can be considered dermally non-toxic.
