MAIN STUDY
The four groups of four female mice were subjected to application of the vehicle or one of the test formulations to the outer aspect of the auditory pinnae, once daily on Days 1, 2 and 3.
On Day 6 the mice were placed in a warming cabinet in order to dilate the peripheral blood vasculature and thus facilitate intravenous dosing. Each mouse was transferred to a cylindrical restrainer. A plastic syringe and fine gauge hypodermic needle were used to administer 0.25 mL phosphate buffered saline incorporating 20 μCi of 3HTdR into a tail vein of each mouse by slow bolus injection. After this treatment the mice were returned to their cages.
Approximately five hours after intravenous injection of the 3HTdR, all mice were killed by exposure to a rising concentration of carbon dioxide. Killing was organised to minimise the interval between death and the recovery of the auricular lymph nodes to no more than fifteen minutes.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- The Local Lymph Node Assay demonstrated that TOFA_TETA_PAA_BADGE_CGE_Adduct has the potential to cause skin sensitisation.
The test article was classified as a Category 1 sensitiser according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). - Executive summary:
This study was conducted to assess the potential of the test article, TOFA_TETA_PPA_BADGE_BGE_Adduct, to cause skin sensitisation in the mouse.
Following a preliminary screening test using a 50% w/v formulation, the test article was prepared for administration at 10, 25 and 50% w/v in 80% v/v acetone in olive oil. Groups of four female CBA/CaCrl mice were subjected to topical applications of vehicle or of the test formulations to the outer aspect of the auditory pinnae once daily on Days 1, 2 and 3. On Day 6 a 20 µCi dose of tritiated 3H-methyl thymidine was injected intravenously into each mouse. Approximately five hours later the auricular lymph nodes were recovered from each animal. The nodes from mice subjected to the same treatment were pooled and suspensions of the cellular components of the lymph node were prepared in 5% w/v trichloroacetic acid and processed through a scintillation counter.
Test results are expressed in terms of Stimulation Indices, the ratios of the mean scintillation count per group obtained from the test groups relative to the corresponding mean scintillation count from the controls. The threshold level for the Stimulation Index to be considered a positive indicator of the potential to cause skin sensitisation is 3.0.
