ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-22 °C
- Humidity (%): 60-85%
- Photoperiod: 12 hrs dark / 12 hrs light
IN-LIFE DATES: From: To: 09 - 23 August 1988
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- other: 1% aqueous methyl cellulose
- Details on dermal exposure:
- TEST SITE
The test substance was suspended in 1% aqueous methyl cellulose and spread on a surgical gauze (5x5 cm and 5x3.5 cm for males and females, respectively). This was fixed to, successively, aluminium foil and flexible bandage with drops of vaseline. This patch was then applied to the clipped area of each animal and fixed with adhesive tape.
REMOVAL OF TEST SUBSTANCE
After 24 hrs of exposure, the semi-occlusive bandage was removed and the remaining test substance was gently removed with tissues, moistened with tap water. The day of application of the test substance was considered as day 0.
TEST MATERIAL
The dose level was 2000 mg/kg bw and the dose volume was 20 ml/kg bw.
- Constant volume or concentration used: yes - Duration of exposure:
- 24 hrs
- Doses:
- 2000 mg/kg bw (males and females)
- No. of animals per sex per dose:
- 5 males + 5 females
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Clinical observations were performed on the day of dosing (approximately once every two hours) and once daily thereafter for 14 days. Any signs of toxicity were recorded along with the time of onset and duration. Individual bodyweights were measured weekly.
- Necropsy of survivors performed: yes
- Other examinations performed: In addition, observations regarding changes of the treated surface were performed following bandage removal and on days 4, 7 and 14. At the end of the study (day 14) all animals were anaesthetised by CO2/O2 inhalation, subsequently killed by CO2 and subjected to necropsy.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occured.
- Clinical signs:
- other: No signs of toxicity were oberved during the 14 day observation period (with the exception of one animal showing hypothermia at the time of bandage removal, most probably due to tight application of the bandage). Following bandage removal and until day 4
- Gross pathology:
- Macroscopic examination at necropsy of all animals at the end of the study did not reveal any changes that were considered to have arisen as a result of treatment.
Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
