- Route:
- epicutaneous, occlusive
- Vehicle:
- other: methylcellulose (1%)

- No. of animals per dose:
- In the range finding study: 2 animals / 2 concentrations (2 concentrations in 1 animal: one on the right side and the other on the left side)
Main study: test groups - 10 animals
control group - 5 animals - Details on study design:
- 10 test animals were subjected to sensitization procedures in a two stage operation, i.e. intradermal treatment and a topical application.
The test item was used in concentration of 0.01% for intradermal injections and in concentration of 75 % (w/v) for dermal sensitization treatment. Before Before the dermal exposure the test area was painted with 0.5 ml of 10% sodium lauryl sulphate in vaseline 24 h prior to the topical induction application, in order to create a local irritation.
Two weeks following the last induction exposure, a challenge dose (in concentration 75%) was administered. Challenge was performed by dermal application of the test item. - Challenge controls:
- 5 control guinea pigs were simultaneously exposed to vehicle during induction treatments and they were treated with the test item on the challenge day only.
