Constituent 1
In vivo test system
Test animals
- Species:
- mouse
- Strain:
- CBA
- Sex:
- female
- Details on test animals and environmental conditions:
- Mice, CBA/Ca01aHsd, female, age 8 – 12 weeks, 5 mice per test group.
Study design: in vivo (LLNA)
- Vehicle:
- acetone/olive oil (4:1 v/v)
- Concentration:
- A preliminary test was performed first to detect the highest application solution. The maximum technically applicable concentration was found to be 50%. Based on the results of this preliminary test the test item was assayed at three concentrations: 12,5%, 25%, 50% (w/v).
- No. of animals per dose:
- 5 mice per test group; 3 test groups (3 different concentrations) and 1 Negative Control Group (vehicle) were tested.
- Positive control substance(s):
- other: p-Phenylenediamine
Results and discussion
- Positive control results:
- The stimulation index observed in the historical positive control group of the BSL study no. 073846 with 1% p-Phenylendiamine was 8.1.
In vivo (LLNA)
Results
- Parameter:
- other: disintegrations per minute (DPM)
- Remarks on result:
- other: Table 3: Radioactive determination of the test substance groups. If not noted individually, results include both lymph nodes of an animal.
Any other information on results incl. tables
Summary Results:
None of the three tested concentrations of the test item reached the stimulation index of 3.
The stimulation index at a concentration of 12.5% was 0.8
The stimulation index at a concentration of 25% was 0,7
The stimulation index at a concentration of 50% was 0.9
Weight development of all animals was within the expected range, which includes a weight loss of up to 2 g throughout the study.
At the daily clinical observation the animals did not show any visible clinical symptoms.
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- The EC3 value (derived by linear interpolation) could not be stated, as all measure points were below the stimulation index of three.
Considering the reported data of this sensitization test it can be stated that the test item causes no reactions identified as sensitization, as the stimulation index was below 3.0 for each concentration tested.
