Study design: in vivo (LLNA)
- Vehicle:
- acetone/olive oil (4:1 v/v)
- Concentration:
- Preliminary test: 25% w/w
Main test: 5, 10 and 25% w/w - No. of animals per dose:
- 4
- Details on study design:
- RANGE FINDING TESTS:
- Compound solubility: the maximum concentration that could be formulated in any solvent was 25% w/w. The substance was soluble at this level in the preferred solvent, 4:1 acetone/olive oil
- Irritation: observations for any irritancy were made, as well as for signs of systemic toxicity, clinical signs, bodyweight and mortality
- Lymph node proliferation response: not performed
MAIN STUDY
ANIMAL ASSIGNMENT AND TREATMENT
- Name of test method: Local Lymph Node assay
- Criteria used to consider a positive response: a test item is regarded as a sensitiser in the LLNA if the exposure to one or more test concentrations results in a 3-fold or greater increase in incorporation of 3HTdR compared with concurrent controls, as indicated by the Stimulation Index (S.I.).
TREATMENT PREPARATION AND ADMINISTRATION:
The test material was freshly prepared in acetone/olive oil 4:1. This vehicle was chosen as it produced the highest concentration that was suitable for dosing.
Each of four animals, were treated with 50 µl (25 µl per ear) of the test material as a suspension in acetone/olive oil 4:1 at concentrations of 25%, 10% or 5% w/w. A further group of four animals was treated with acetone/olive oil 4:1 alone. - Positive control substance(s):
- hexyl cinnamic aldehyde (CAS No 101-86-0)
Results and discussion
- Positive control results:
- Formulated in cottonseed oil:
10% v/v SI index, 1.52, negative
25% v/v SI index, 2.63, negative
50% v/v SI index, 5.07, positive
Conclusion: hexylcinnamaldehyde is a sensitiser under the conditions of the test

Any other information on results incl. tables
Preliminary test
No signs of systemic toxicity were observed and therefore the main test was conducted at dose levels of 5, 10 and 25% w/w.
Main test
A stimulation index of less than 3 was recorded for the three concentrations of the test material (25%, 10 % and 5% w/w).
There were no deaths. No signs of systemic toxicity were noted in the test or control animals during the test.
Bodyweight changes of the test animals between Day 1 and Day 6 were comparable to those observed in the corresponding control group animals over the same period.
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material was considered to be a non-sensitiser under the conditions of the test.
