Test material
Constituent 1
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Batch No.of test material: SK03/186
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature; no direct sunlight
In vitro test system
- Test system:
- human skin model
- Source species:
- human
- Cell type:
- non-transformed keratinocytes
- Vehicle:
- other: PBS
- Details on test system:
- TEMPERATURE USED FOR TEST SYSTEM
- Temperature used during treatment / exposure: The tissues were kept under the laminar flow hood at room temperature for 25 minutes overall
and for 35 minutes in the incubator.
REMOVAL OF TEST MATERIAL AND CONTROLS
The tissues were washed with sterile PBS 1 hour after start of application.
DYE BINDING METHOD
- Dye used in the dye-binding assay: MTT
- Spectrophotometer: SunriseTM Absorbance Reader
- Wavelength: 570 nm
DECISION CRITERIA
Irritant potential of the test materials is predicted from the mean relative tissue viabilities compared to the negative control tissues concurrently treated with sterile PBS. A chemical is considered as "irritant", if the mean relative tissue viability with a test material is less than or equal to 50%. - Control samples:
- yes, concurrent negative control
- yes, concurrent positive control
- yes, concurrent MTT non-specific colour control
- Amount/concentration applied:
- 25 μL sterile PBS was applied first. Thereafter, a bulk volume of ca. 25 μL of the solid test material was applied and homogeneously distributed together with the fluid.
Control tissues were concurrently applied with 30 μL of sterile PBS (NC) or with 30 μL of 5% SDS (PC). - Duration of treatment / exposure:
- 1 hour
- Duration of post-treatment incubation (if applicable):
- 42 hours
After the postincubation period, the assay medium was replaced by 0.3 mL MTT solution and the tissues were incubated in the incubator for 3 hours. - Number of replicates:
- 3

Applicant's summary and conclusion
- Conclusions:
- Based on the observed results and applying the evaluation criteria, it was concluded, that [1,1'-Biphenyl]-2-amine, 3',4',5'-trifluoro- does not show a skin
irritation potential in the EpiDerm™ in vitro skin irritation test under the test conditions chosen.
