MAIN STUDY
ANIMAL ASSIGNMENT AND TREATMENT
- Name of test method: local lymph node assay
- Criteria used to consider a positive response: DPM values are presented for each animal and for each dose group. A Stimulation Index (SI) is calculated for each group. The SI is the ratio of the DPM/group compared to DPM/vehicle control group. If the results indicate a SI >= 3, the test substance may be regarded as a skin sensitiser, based on the test guideline and recommendations done by ICCVAM
TREATMENT PREPARATION AND ADMINISTRATION:
Three groups of five experimental animals were treated with test substance concentrations of 10%, 25% or 50% on three consecutive days, by open application on the ears (25 µl/ear). Five vehicle control animals were similarly treated, but with vehicle alone (Acetone/Olive oil (4:1 v/v)).
Three days after the last exposure, all animals were injected with 3H-methyl thymidine and after five hours the draining (auricular) lymph nodes were excised. After precipitating the DNA of the lymph node cells, radioactivity measurements were performed. - Positive control substance(s):
- hexyl cinnamic aldehyde (CAS No 101-86-0)
Results and discussion
- Positive control results:
- The SI values calculated for the substance concentrations 5, 10 and 25% were 1.0, 2.0 and 5.7 respectively. An EC3 value of 14.1% was calculated using linear interpolation. The calculated EC3 value was found to be in the acceptable range of 2 and 20%. The results of the 6 monthly HCA reliability checks of the recent years were 10.3, 9.5, 13.1 and 15.6%. Based on the results, it was concluded that the Local Lymph Node Assay as performed at NOTOX is an appropriate model for testing for contact hypersensitivity.

Any other information on results incl. tables
Slight erythema was observed in one or both ears of two animals at 50%. No oedema was observed in any of the animals examined.
The irritation of the ears as shown by the animals was considered not to have a toxicologically significant effect on the activity of the nodes.
The scoring of the skin reactions was not hampered by sticky remnants of the test substance, which were present on the ears of experimental animals at the time of scoring.
The majority of nodes were considered normal in size, except for the enlarged nodes observed in all animals at 50%.
No macroscopic abnormalities of the surrounding area were noted.
Body weights and body weight gain of experimental animals remained in the same range as controls over the study period.
Applicant's summary and conclusion
- Interpretation of results:
- sensitising
- Remarks:
- Migrated information EC3 of 28.7%
- Conclusions:
- The SI values calculated for the substance concentrations 10, 25 and 50% were 0.6, 1.9 and 8.3 respectively. These results indicate that the test substance could elicit an SI >= 3. An EC3 value of 28.7% was calculated.
Based on these results, Corsair Clear #34 would be regarded as skin sensitizer.
