MAIN STUDY
TREATMENT PREPARATION AND ADMINISTRATION:
The test substance was solved in N,N-Dimethylformamide (DMF) and was administered to three groups of 5 female CBA/Ca mice. Administration was performed epicutaneously to the dorsal surface of both ears, once a day on three consecutive days (Days 1-3). The volume administered was 25 μL per ear. On Day 6, 20 µCi ³HTdR was injected to all mice via tail vein. After 5 h, the drainig auricular lymph nodes were excised and pooled for each group. A single cell suspension was prepared and incorporation of ³HTdR was determined with a β-scintillation counter. - Positive control substance(s):
- hexyl cinnamic aldehyde (CAS No 101-86-0)

Any other information on results incl. tables
All animals survived until the end of the study period. No adverse effects were noted in all animals of all test substance groups and the negative control group. Moderate erythema formation was noted in all animals of the positive control group on Days 2 and 3, indicating slight local skin irritation.
No skin irritating effects were observed in the test substance groups and the negative control group throughout the whole study period.
