TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: Applied as supplied - Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Three male and 3 female New Zealand White rabbits (order weight 2.5 kg-3.0 kg) were used. They were supplied by a Reputable Commercial Supp;ier and arrived at Ithe test site on 17-February 1987. They were housed individually in aluminium cages with grid floors beneath which were peat moss filled trays. They were fed on Special Diet Services Rabbit Diet of satisfactory anaJysis and allowed food and water ad libitum A 12 h light/dark cycle was in operation.
Mean environmental max.imum and minimum temperatures were 17°C and 15°C and mean relative humidity was 60°%.
The animals were allowed an acclimatisation period of 8 days before test commencement. - Type of coverage:
- occlusive
- Preparation of test site:
- other: two test sites prepared both were shaved and one was also abraded before application.
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not specified
- Amount / concentration applied:
- 0.5mL
- Duration of treatment / exposure:
- 24 h
- Observation period:
- 24h and 72h after patch application
- Number of animals:
- 6
- Details on study design:
- The hair was clipped from the back of each rabbit approximately 24 h before treatment.
The test material (0.5 ml} was applied to each rabbit under two 2.5 cm x 2.5 cm patches of gauze. One site was abraded before application using a sterilin blood lancet.
The patches were covered with Blenderm tape and the entire trunk was bound with Sleek occlusive tape which remained in position for 24 h.
At the end of this period the patches were removed and the skin wiped with damp tissues to remove surplus test material. - Irritation parameter:
