- Executive summary:
The objective of this study was to evaluate the potential of CD 6002 SE to produce a dermal sensitization response in the mice using the local lymph node assay (LLNA). Five groups of 5 female mice were dosed for 3 consecutive days with 0% (vehicle control ), 1%, 5%, 10 % or 25 % CD 6002 SE on both ears. N,N-dimethylformamide was used as the diluting vehicle. One group of five female mice was
dosed for 3 consecutive days with 25 % hexylcinnamaldehyde (HCA) in 4:1 acetone:olive oil (AOO) as a positive control and one group of five female mice was dosed for 3 consecutive days with AOO as positive control vehicle. On test day 5 of the assay, mice received ³H-Thymidine by tail vein injection and were sacrificed approximately 5 hours later. The cell proliferation in the draining auricular lymph nodes of the ears from the test substance group was than evaluated and compared to the vehicle control group.
No statistically significant differences in mean body weight and body weight gains compared to the vehicle control group were observed ant any test concentration. No clinical signs of toxicity were observed in the study.
No statistically significant increases in cell proliferation measurements compared to the vehicle control group were observed at any test concentration. Stimulation indexes less than 3.0 were observed at all test concentrations of CD 6002 SE. Therefore, the EC3 value for the test substance under the conditions of this study was not calculable. A 25 % concentration of the positive control, HCA, produced a dermal sensitization response in mice. Therefore, the LLNA test system was valid for this study with CD 6002 SE. Under the conditions of this study , CD 6002 SE did not produced a dermal sensitization response in mice.
Based on these data, CD 6002 SE is not a dermal sensitizer.
