- Approximately three days before treatment the dorsal fur was clipped with an electric clipper, exposing an area of approximately 100m2 (10cm x 10 cm). The skin of the animals was examined approximately 24 hours before treatment and if necessary regrown fur was again clipped.
On the day of treatment the test substance was applied to approximately 6cm2 of the intact skin of the clipped area. It was covered with a 25 cm x 25 cm patch of surgical gauze and the gauze was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape.
The duration of the treatment was 4 hours. Then the dressing was removed and the skinwas flushed with lukewarm tap water to clean the applicationsite so that any reactions (erythema) were clearly visible at that time.
Observations
Mortality/ viability: daily
Clinical signs: daily during the observation period
Body weights: a start of acclimatization, in the first day of application and at termination of observation
Irritation scores
The skin reaction was assessed according to the numerical scoring system listed in the EEC Comission Directive 92/69/EEC, 1992 at approximately 1, 24, 48 and 72 hours after the removal of the dressing gaze patch and test substance.
Pathology
No necropsy was performed in the animals acrifficed at termination of observation. All rabbits were sacrifices by an intravenous injection of Narcoren into the ear vein of at least 1 ml/kg body weight. - Irritation parameter:

- Executive summary:
A study was conducted to determine the skin irritation potential of the test substance according to OECD Guideline 404 and EU Method B.4, in compliance with GLP. The primary skin irritation potential of the test substance was investigated by topical application of 0.5 g to 6 cm2 of intact dorsal skin of each of three young adult New Zealand White rabbits. The duration of the treatment was 4 h. The scoring of skin reactions was performed at 1, 24, 48 and 72 h after removal of the dressing. The scores of each animal at 24, 48 and 72 h were used in calculating the respective mean values for each type of lesion. The primary irritation score was calculated by totalling the individual cumulative scores at 24, 48, 72 h and then dividing by the number of data points. The primary irritation score was 0.00 (max. 8.0). Local signs consisted of grade 0.00 oedema (mean values from 24 to 72 h) and grade 0.00 erythema (mean values from 72 h). The test substance caused violet-red staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval. Under the study conditions, the test substance was considered to be not irritating to rabbit skin (Braun, 1998)..

The lids were then gently held together for about one second to prevent loss of test substance. The right eye remained untreated and served as the reference control. The treatment eyes were rinsed gently with physiological saline approximately 24 hours after administration.
