Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Age on day 0: Young adult animals (male animals approx. 8 weeks, female animals approx. 12 weeks)
Arrival in the testing facility: Acclimatization period at least 5 days before the beginning of the experimental phase; during the acclimatization period, the animals were accustomed to the environmental conditions of the study and to the diet.
Identification: Individual identification by cage cards and tail marking.
Body weight on day 0: Animals of comparable weight
Room temperature/relative humidity: The rats were housed in fully air-conditioned rooms. Central air-conditioning guaranteed a range of 22 – 26°C for temperature and of 20 – 80% for relative humidity.
Day / night rhythm: 12 h / 12 h (6.00 a.m. – 6.00 p.m. / 6.00 p.m. – 6.00 a.m.)

Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- Clipping of the fur: About 24 hours before administration
Route of application: Single application to the clipped epidermis (dorsal and dorsolateral parts of the trunk); covering of the application site with a semi occlusive dressing (the bandage consists of four layers absorbent gauze, Ph. Eur. Lohmann GmbH & Co. KG and Fixomull stretch (adhesive fleece), Beiersdorf AG) for 24 hours, afterwards removal of the dressing. Rinsing of the application site with warm water. - Duration of exposure:
- 24 h

- no
- Details on study design:
- Application area: About 40 cm² (corresponds to at least 10% of the body surface)
Time of day of application: In the morning
Observation period: 14 days
Body weight determination: Individual body weights shortly before administration (day 0), weekly thereafter and on the last day of observation.
Clinical observations: Recording of clinical signs several times on the day of administration, and at least once daily thereafter each workday for the individual animals.
Scoring of skin findings: Individual readings 30 – 60 minutes after removal of the semi-occlusive dressing (day 1), several times until the last day of observation.
Mortality: A check for any dead or moribund animal was made at least once each workday, these records are archived by Bioassay.
Pathology: Necropsy with gross-pathology examination on the last day of the observation period after sacrifice with CO2 in a chamber with increasing concentrations over time.
