- RANGE FINDING TESTS:
To determine the highest non-irritant test concentration, a pre-test was performed in two animals. Two mice were treated with concentrations of 2.5, 5, 10, and 20 % on one ear each on three consecutive days. Clinical signs were recorded 24 ± 4 hours after each application. At the tested concentrations the animals did not show any signs of irritation or systemic toxicity.
The test item in the main study was assayed at 5, 10 and 20 %. The top dose is the highest technically achievable concentration whilst avoiding systemic toxicity and excessive local irritation. No severe irritant effects were tolerated choosing the test concentrations.
MAIN STUDY
ANIMAL ASSIGNMENT AND TREATMENT
- Name of test method:
- Criteria used to consider a positive response:
TREATMENT PREPARATION AND ADMINISTRATION: - Positive control substance(s):
- hexyl cinnamic aldehyde (CAS No 101-86-0)
- Statistics:
- The mean values and standard deviations were calculated in the body weight tables.
A statistical analysis was conducted for assessment of the dose-response relationship, and the EC3 value was calculated according to the equation
EC3 = (a-c) [(3-d)/(b-d)] + c
where EC3 is the estimated concentration of the test item required to produce a 3-fold increase in draining lymph node cell proliferative activity; (a, b) and (c, d) are respectively the co-ordinates of the two pair of data lying immediately above and below the S.I. value of 3 on the local lymph node assay dose response plot.
Results and discussion
- Positive control results:
- - Experiment performed in July 2008, 5 % (w/v) alpha-Hexylcinnamaldehyde yielded a S.I. of 5.24, 25 % yielded a S.I. of 9.32

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- The test item FAT 40842/A TE was found to be not a skin sensitiser under the described test conditions.
- Executive summary:
The present study (Honrvar 2008) analyzes the sensitizing potential of potential of FAT 40842/A TE.
Three groups each of four female mice were treated daily with the test item at concentrations of 5, 10 and 20 % in dimethylformamide by topical application to the dorsum of each ear lobe (left and right) for three consecutive days. A control group of four mice was treated with the vehicle (dimethylformamide) only. Five days after the first topical application the mice were injected intravenously into a tail vein with radio-labelled thymidine (3H-methyl thymidine). Approximately five hours after intravenous injection, the mice were sacrificed, the draining auricular lymph nodes excised and pooled per group. Single cell suspensions of lymph node cells were prepared from pooled lymph nodes, which were subsequently washed and incubated with trichloroacetic acid overnight. The proliferative capacity of pooled lymph node cells was determined by the incorporation of 3H-methyl thymidine measured in a beta-scintillation counter.
All treated animals survived the scheduled study period and no signs of toxicity were observed.
A test item is regarded as a sensitiser in the LLNA if the exposure to one or more test concentration resulted in 3-fold or greater increase in incorporation of 3HTdR compared with concurrent controls, as indicated by the Stimulation Index (S.I.). The estimated
concentration of test item required to produce a S.I. of 3 is referred to as the EC3 value.
In this study Stimulation Indices of 1.76, 1.07 and 2.78 were determined with the test item at concentrations of 5, 10 and 20 % in dimethylformamide.
The EC3 value could not be calculated, since none of the tested concentrations induced an S.I. greater than 3.
The test item FAT 40842/A TE was found to be not a skin sensitiser under the described conditions.
