- Diet: standard pelleted laboratory animal diet (Altromin VRF 1, Lage, Germany), ad libitum
- Water: tap water, ad libitum
- Acclimation period: at least 5 days before start of treatment

ENVIRONMENTAL CONDITIONS

IN-LIFE DATES: From: To: From 2004-02-12 To 2004-03-04

Administration / exposure

Type of coverage:
occlusive
Vehicle:
unchanged (no vehicle)
Details on dermal exposure:
TEST SITE
- Area of exposure: approx. 25 cm²
- % coverage: approx. 10%
- Type of wrap if used: The test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch, successively covered with an aluminium foil and Coban elastic bandage. A piece of Micropore tape was additionally used for fixation of the bandages in females only.

REMOVAL OF TEST SUBSTANCE
- Washing: the skin was cleaned of residual test substance using water
- Time after start of exposure: 24 h

TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2000 mg/kg bw (1.3 mL/kg bw, based on specific gravity)
Duration of exposure:
24 h
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
5
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: twice daily
Body weights: days 1 (pre-administration), 8 and 15
Clinical signs: at periodic intervals on the day of dosing (day 1) and once daily thereafter until day 15.
- Necropsy of survivors performed: yes

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: Chromodacryorrhea, flat and/or hunched posture were noted among all animals between days 1 and 3. In addition, scales were seen on the treated skin area of two females during the observation period.
Gross pathology:
No toxicologically relevant abnormalities were found at macroscopic post-mortem examination of the animals.
Pelvic dilation of the kidneys found in one animal is commonly noted among rats of this age and strain and was therefore not considered of toxicological relevance.
