The controls confirmed the validity of the study. The mean OD570nm of the two negative control tissues was ≥ 0.8 and ≤ 2.8 for each exposure period (1.760, 1.747). The mean relative tissue viability (% negative control) of the positive control was ≤ 15% (6.1%) after 60 min treatment. The coefficient of variation (CV) (in the range of 20 – 100% viability) of replicate tissues of all dose groups was ≤ 30% (0.6% - 7.2). - Interpretation of results:
- other: non-corrosive
- Conclusions:
- In this study under the given conditions the test item showed no corrosive effects. The test item is
classified as “non-corrosive“. - Executive summary:
In the present study the skin corrosivity potential of SAT 200028 was analysed. Since corrosive chemicals are cytotoxic after a short time exposure to the stratum corneum of the epidermis the cytotoxic effects of the test item on EpiDerm, a reconstituted three-dimensional human epidermis model, were determined. Hereby, the test item was applied topically. Cytotoxicity is expressed as the reduction of mitochondrial dehydrogenase activity measured by formazan production from MTT after a 3 min and 60 min exposure period and compared to those of the concurrent negative controls.
The test item has no non-specific MTT-reducing or colouring potential, therefore no additional controls were necessary.
The test item showed no corrosive effects. The mean relative tissue viability (% negative control) was ≥ 50% (97.9%) after 3 min treatment and ≥ 15% (94.2%) after 60 min treatment.- Endpoint:

Pre-Experiments
The mixture of 50 μL test item per 1 mL MTT medium showed no reduction of MTT as compared to the solvent. The mixture did not turn blue/purple. Therefore, NSMTT equalled 0%.
The mixture of 50 μL test item per 300 μL Aqua dest. and per 90 μL isopropanol showed no colouring as compared to the solvent. Therefore, NSC equalled 0%.
The test item showed no non-specific reduction of MTT and no relevant colouring potential after mixture with aqua dest. and with isopropanol. Therefore, no additional controls for correction of possible false-negative results were necessary.
Main Test
Corrosivity potential of the test item was predicted from the relative mean tissue viabilities obtained after both treatment periods had been compared to the corresponding negative control tissues.
The test item has no non-specific MTT-reducing or colouring potential, therefore no additional controls were necessary.
The test item showed no corrosive effects. The mean relative tissue viability (% negative control) was ≥ 50% (97.9%) after 3 min treatment and ≥ 15% (94.2%) after 60 min treatment.
Pre-Experiments
To check the non-specific MTT-reducing capability of the test item 30 μL of the test item was mixed per 1 mL MTT medium and incubated for 60 min at 37 ± 1 °C in the incubator. A phase separation was observed. The mixture did not turn blue/purple. Thus, the additional test with freeze-killed tissues and the quantitative corrections were not necessary.
To check the colouring potential of the test item 30 μL of the test item was mixed per 300 μL aqua dest. and/or per 300 μL isopropanol each in a transparent recipient and incubated at 37 ± 1°C for 60 min. A phase separation was observed. The mixture showed no colouring detected by unaided eye-assessment. Thus, the additional test with viable tissues and the quantitative corrections were not necessary.
The test item showed no non-specific reduction of MTT and no relevant colouring potential after mixture with aqua dest. and with isopropanol. Therefore, no additional controls for correction of possible false-negative results were necessary.

Irritant potential of the test item was predicted from the relative mean tissue viabilities obtained compared to the corresponding negative control tissues concurrently treated with DPBS.
The test item has no non-specific MTT-reducing or colouring potential, therefore no additional controls were necessary.
The test item showed no irritant effects. The mean relative tissue viability (% negative control) was > 50% (97.3%) after 60 min treatment and 42 h post-incubation.

- Details on test animals or tissues and environmental conditions:
- The assay uses isolated corneas obtained as a by-product from animals freshly slaughtered at the abattoir Vion Beef B.V., Buchloe, Germany.
On the test day, fresh eyes were collected from the slaughterhouse and were transported in HBSS containing Pen/Strep on ice to the laboratories. Immediately after arrival of the eyes, cornea preparation was initiated.
The eyes were carefully examined for defects and any defective eyes were discarded. - Vehicle:

- Amount / concentration applied:
- 750 µL
- Duration of treatment / exposure:
- 10 Min
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- Preparation of the Corneas
The tissue surrounding the eyeball was carefully pulled away and the cornea was excised leaving a 2 to 3 mm rim of sclera. The isolated corneas were stored in a petri dish containing HBSS. Before the corneas were mounted in corneal holders (Duratec GmbH) with the endothelial side against the O-ring of the posterior chamber, they had been visually examined for defects and any defective cornea had been discarded. The anterior chamber was then positioned on top of the cornea and tightened with screws. The chambers of the corneal holder were then filled with RPMI 1640 medium (without phenol red) containing 1% FBS and 2 mM L-glutamine (complete RPMI 1640 medium). The posterior chamber was always filled first. The corneas were incubated for one hour at 32 +/- 1 °C.
Calibration of the Opacitometer
The opacitometer (BASF-OP3.0, Duratec GmbH) was switched on at least 15 min before starting the calibration procedure. The filter holder was placed into the opacitometer and the readout was adjusted to 1000 ± 10 lux using the “Calibrate”-turning knob. For calibration the glass filter F2 was introduced into the filter holder. The readout lay in the range between 540-560 lux. To test the linearity of the measurement, two additional calibration filters, glass filter F3 and glass filter F4, were measured. For these glass filters, the opacitometer displayed values between 300-310 lux and between 90-100 lux. The calibration procedure was performed before the test and is documented in the raw data.
Treatment of the Corneas
After the equilibration period, the medium was removed from both chambers and replaced with fresh complete RPMI 1640 medium. An initial measurement was performed on each of the corneas using the opacitometer. Three corneas with illuminance readings approximately equivalent to the median illuminance of all corneas were selected as negative-control corneas. The illuminance of each cornea was read and recorded. Only corneas that had an initial illuminance reading I > I0/1.1651 lux were used for the assay. The medium was removed from the anterior chamber and replaced with the test item or control.
750 µL of the test substance or the control substance was introduced into the anterior chamber. After 10 minutes incubation at 32 +/- 1 °C either the test substance or the control substance was removed and the epithelium washed at least three times with MEM (containing phenol red). Once the medium was free of test substance, the cornea was finally rinsed with complete RPMI 1640 medium (without phenol red). The anterior chamber was refilled with complete RPMI 1640 medium and an illuminance measurement was performed after 2 hours incubation at 32 +/- 1 °C. Also, each cornea was observed visually and pertinent observations were recorded.
After the illuminance measurement was performed, the medium was removed from both chambers of the holder. The posterior chamber was refilled with fresh complete RPMI 1640 medium. 1 mL of a 4 mg/mL sodium fluorescein solution was added to the anterior chamber and the corneas were incubated for 90 minutes at 32 +/- 1 °C. Then the medium from the posterior chamber was removed and its optical density at 490 nm (OD490) was determined, using a spectrophotometer (Jenway 6405 UV/VIS).
