IN-LIFE DATES: From: 09 Oct 2012 To: 23 Oct 2012

Administration / exposure

Type of coverage:

semiocclusive

Vehicle:

unchanged (no vehicle)

Details on dermal exposure:

TEST SITE
- Area of exposure: about 40 cm² clipped skin of the dorsal and dorsolateral parts of the trunk
- % coverage: ca. 10
- Type of wrap if used: the application site was covered with a semi-occlusive dressing (4 layers of absorbent gauze; Ph. Eur. (Lohmann GmbH & Co., KG)) and stretch bandage (Fixomull® Stretch (adhesive fleece) (Beiersdorf AG)).

REMOVAL OF TEST SUBSTANCE
- Washing (if done): the application site was rinsed with warm water
- Time after start of exposure: 24 h

TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 5.2 mL/kg bw

Duration of exposure:

24 h

Doses:

5000 mg/kg bw

No. of animals per sex per dose:

5

Control animals:

not required

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: animals were observed for clinical signs several times on the day of administration and at least once daily thereafter each workday for the individual animals. A check for mortalities was made at least once each workday. Scoring of skin reaction according to Draize was performed 30-60 minutes after removal of the semi-occlusive dressing (after 24 h), weekly thereafter and on the last day of observation. Individual body weights were determined shortly before administration (Day 0), weekly thereafter and on the last day of observation.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, scoring of skin reactions

Statistics:

Mean values and standard deviations of body weights were determined.
