- acetone/olive oil (4:1 v/v)
- Concentration:
- 10, 25 and 50% v/v
- No. of animals per dose:
- 2 per dose
- Details on study design:
- Preliminary investigation:
Two female mice (per concentration) received a daily application of 25 µL of appropriate concentration of the test substance to the dorsal surface of each ear for three consecutive days (Days 1-3). The test substance was applied to the dorsal surface of each ear using an automatic micropipette and was spread
over the entire dorsal surface of the ear using the tip of the pipette.
Main phase
Groups of four mice were treated at one of three concentrations of the test substance. The mice were treated by daily application of 25 µL of the appropriate
concentration of the test substance to the dorsal surface of each ear for three consecutive days (Days 1-3). The test was applied to the dorsal surface of each ear using an automatic micropipette and was spread over the entire dorsal surface of the ear using the tip of the pipette. Further groups of four mice received the vehicle alone or the positive control substance in the same manner. - Positive control substance(s):
- hexyl cinnamic aldehyde (CAS No 101-86-0)
Results and discussion
- Positive control results:
- The SI for the positive control substance hexyl cinnamic aldehyde (HCA) was 6.5 which demonstrates the validity of this study.
