IN-LIFE DATES: From: 21 July 1993 To: 04 August 1993
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- Approximatively 24 h prior to administration, the dorsal area of the trunk of each animal was clipped free of hair. The prepared site was approximatively 10% of the body surface and remained intact.
The test article was melted into a liquid and the dose was based on the sample weight as calculated from the specific gravity. The test article was applied to the dermal site, one time, by seringue type applicator at a dose level of 2.0 g/kg. The test site was covered with a gauze patch, secured with non-irritating tape. At 24 h, the patches were removed. Any residual test article was wiped with gauze prior to observations. - Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5/dose
- Control animals:
- not required
- Details on study design:
- - Duration of observation period following administration: 14 days
- The test sites were scored for dermal irritation at 24 h post dose and on days 7 and 14 using the numerical Draize scale. Additional signs were described.
- The animals were observed 1, 2 and 4 h post dose and once daily for 14 days for toxicity and phamaclogical effects. The animals were observed twice daily for 14 days for mortality.
- Bodyweights were recorded pretest, weekly and at death or termination.
- All animals were examined for gross pathology. Abnormal tissues were preserved in 10% buffered formalin for possible future microscopic examination. - Statistics:
- The LD50, 95% confidence limits, dose response curve and slope were calculated, if possible, by the method of Litchfield & Wilcoxon, 1949.
Results and discussion
- Preliminary study:
- Not applicable
Effect levels
- Key result
- Sex:
- not specified
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- One male was found dead on Day 14 with predeath signs of diarrhea and few feces.
- Clinical signs:
- other: Instances of diarrhea and few feces were noted in some surviving animals (2 males and 1 female)
- Gross pathology:
- Necropsy of the dead animal revealed abnormalities of the gastrointestinal tract and lungs as well as soiling of the anogenital area. Necropsy of survivors revealed treated skin abnormalities in all animals, one of which also exhibited excess fluid in the peritoneal cavity.
- Other findings:
- - Dermal reactions: dermal reactions were absent to well defined on days 1 and 7; slight to well defined on day 14. However, it was not possible to completely remove the test item from the dose site without injuring the skin.

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified according to CLP
- Conclusions:
- Under the test conditions, the dermal LD50 of the test substance is > 2000 mg/kg bw in rabbits therefore it is not classified according to the Regulation (EC) N° 1272-2008. One death occurred at this dose level with clinical signs such as diarrhea in survivors therefore it is possible that LD50 is < 5000 mg/kg bw and classified Category 5 according to the GHS.
- Executive summary:
In an acute dermal toxicity study, 5 New Zealand white rabbits/sex/dose were administered a single dermal dose of the test substance at 2000 mg/kg bw for 24 h under semi-occlusive conditions. Animals were then observed for mortality, clinical signs of toxicity and dermal reactions for 14 days.
One male was found dead on Day 14 with predeath signs of diarrhea and few feces. Instances of diarrhea and few feces were noted in some surviving animals (2 males and 1 female). Dermal reactions were absent to well defined on days 1 and 7; slight to well defined on day 14. However, it was not possible to completely remove the test item from the dose site without injuring the skin. Bodyweight changes were normal in 8/9 survivors. One male lost weight during the second week of the observation period. Necropsy of the dead animal revealed abnormalities of the gastrointestinal tract and lungs as well as soiling of the anogenital area. Necropsy of survivors revealed treated skin abnormalities in all animals, one of which also exhibited excess fluid in the peritoneal cavity.
Under the test conditions, the dermal LD50 of the test substance is > 2000 mg/kg bw in rabbits therefore it is not classified according to the Regulation (EC) N° 1272-2008. One death occurred at this dose level with clinical signs such as diarrhea in survivors therefore it is possible that LD50 is < 5000 mg/kg bw and classified Category 5 according to the GHS.
