Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.5 mL of the test substance
- Duration of treatment / exposure:
- 4h
- Observation period:
- Examination of the treated skin was made on removal of the dressings (for 3 minute or
one hour exposures) and approximately 1, 24, 48 and 72 hours later. - Number of animals:
- 3 animals
- Details on study design:
- As the irritancy of the substance was unknown, a single animal was dosed to address potential irritation of the test item. As the response to treatment was considered to be within acceptable limits, a futher 2 animals were dosed, bringing the animal's group size to 3. On the day before dosing a suitable test site was clipped free of hair on both sides of the mid-line of the dorsal surfaces of the trunk of each animal. The test item was used in the form suplied (liquid). A quantity of 0.5ml of the test material was spread evenly over a 2.5cmx 2.5cm cotton gauze pad and placed onto the animal's skin with the test item in direct contact with the skin. A strip of synthetic film was placed over the treated site and the whole assembly held in place by encircling the trunk of the animal with a length of elastic adhesive bandage. At the end of the exposure period the semi-occlusive dressing and gauze pad were removed and the treatment site was washed with lukewarm water (30-40°C) to remove any residual test substance. The treated area was blotted dry with absorbent paper. Mortality and morbidity were observed twice daily. Bodyweight was taken on Day 1 and on termination (Day 4). Examination of the treated skin was made on removal of the dressings (for 3 minute or one hour exposures) and approximately1, 24, 48 and 72 hours after the end of the 4 hour exposure period. Following completion of the observation period the animals were humanely killed by an
intravenous injection of sodium pentobarbital.
