Thomae, Biberach, Germany- Weight at study initiation: 2.5 kg- Housing: individual - Diet: Zucht- / Haltungsdiät - Water: tap water, ad libitum- Acclimation period: at least 7 daysENVIRONMENTAL CONDITIONS- Temperature (°C): 20-21- Humidity (%): 45-50- Photoperiod (hrs dark / hrs light): 12 / 12
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: untreated sites of the same animal served as control
- Amount / concentration applied:
- TEST MATERIAL- Amount(s) applied (volume or weight with unit): 0.5 mL
- Duration of treatment / exposure:
- 4 h
