Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Two male New Zealand White (Hsdlf:NZW) strain rabbits were supplied by Envigo RMS (UK) Limited, Leicestershire, UK. At the start of the study the animals weighed 2.59 or 2.68 kg and were 12 to 20 weeks old. After an acclimatization period of at least 5 days each animal was given a number unique within the study which was written with a black indelible marker pen on the inner surface of the ear and on the cage label.
The animals were individually housed in suspended cages. Free access to mains drinking water and food (2930C Teklad Global Rabbit diet supplied by Envigo RMS (UK) Limited, Oxon, UK) was allowed throughout the study. The diet and drinking water were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
The temperature and relative humidity were set to achieve limits of 17 to 23 °C and 30 to 70% respectively. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
Justification
The rabbit is the preferred species of choice as historically used for irritation studies and is specified in the appropriate test guidelines. The number of animals used was the minimum required to achieve the objectives of the study. Testing was conducted in two animals and the response in those animals was such that exposure of a third animal would not affect classification of the test item, no further testing was needed.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- unchanged (no vehicle)
- Remarks:
- test item moistened with 0.5 ml of distilled water.
- Controls:
- no
- Amount / concentration applied:
- 0.5 g
- Duration of treatment / exposure:
- Four hours
- Observation period:
- 72 hours
- Number of animals:
- Two males
- Details on study design:
- On the day before the test two rabbits were clipped free of fur from the dorsal/flank area using veterinary clippers. Only animals with a healthy intact epidermis by gross observation were selected for the study.
On the day of the test a suitable test site was selected on the back of each rabbit. At each test site a quantity of 0.5 g of the test item, moistened sufficiently with 0.5 mL of distilled water, was introduced under a 2.5 cm x 2.5 cm cotton gauze patch. The patch was secured in position with a strip of surgical adhesive tape. To prevent the animals interfering with the patches, the trunk of each rabbit was wrapped in an elasticated corset and the animals were returned to their cages for the duration of the exposure period.
Four hours after application the corset and patches were removed from each animal and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water.
Immediately following removal of the patches and approximately 1, 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation and scored.
Any other skin reactions and clinical signs of toxicity, if present, were also recorded.
Individual body weights were recorded on Day 0 (the day of dosing) and at the end of the observation period.
Interpretation of results
Calculation of Primary Irritation Index and Grading of Irritancy Potential Using the Draize Scheme
The scores for erythema and edema at the 24 and 72‑Hour readings were totaled for the two test rabbits (8 values) and this total was divided by 4 to give the primary irritation index of the test item.
If irreversible alteration of the dermal tissue is noted in any rabbit, as judged by the Study Director, which include ulceration and clear necrosis or signs of scar tissue, the test item is classified as corrosive to rabbit skin. Classification according to Draize may, therefore, not be applicable.
The results were also interpreted according to theGlobally Harmonized Systemof Classification and Labelling of Chemicals.
