In vitro test system
- Test system:
- human skin model
- Source species:
- human
- Cell type:
- other: Cultured human skin cells
- Cell source:
- other: Cultured human skin cells
- Justification for test system used:
- The EpiDerm™ Skin Model closely parallels human skin, and is recommended by test guidelines. Validation studies have reported that tests employing human skin models are able to reliably discriminate between known skin corrosives and non-corrosives.
- Vehicle:
- unchanged (no vehicle)
- Details on test system:
- EpiDerm™ tissues, Lot No. 27973 Kit D, were received from MatTek Corporation (Ashland, MA) on 06 Mar 2018 and refrigerated at 2-8°C.Before use, tissues were incubated (37±1°C, 5±1% CO2) with assay medium (MatTek) for a one-hour equilibration. Equilibration medium was replaced with fresh medium before dosing.
- Control samples:
- yes, concurrent negative control
- yes, concurrent positive control
- Amount/concentration applied:
- 50 µl of the test article were applied to the top of each EpiDerm™ tissue. A negative control (50 µl of TCH2O) and a positive control (50 µl of KOH) were tested in the same manner. Each treatment with test article or control was conducted in duplicate.
- Duration of treatment / exposure:
- MatTek EpiDerm™ tissues were treated in duplicate with the test article, negative control and positive control for 3 minutes and 60 minutes
- Number of replicates:
- Two

- Other effects / acceptance of results:
- Skin Corrosion is defined as the production of irreversible tissue damage in skin following the application of test material. The percent viability calculated was used to determine corrosivity potential in the following manner:
Mean Viability (3 min.) < 50% = corrosive, Mean Viability (60 mins): Not applicable. From this predicted corrosivity = corrosive
Mean viability (3 min) ≥ 50 % = corrosive, Mean Viability (60 mins): < 15 % . From this predicted corrosivity = corrosive
Mean viability ( 3 min) ≥ 50 % = non-corrosive, Mean Viability (60 mins) :≥ 15 % . From this predicted corrosivity = non-corrosive
Predicted Corrosivity (60 min.) <50% Not Applicable Corrosive ≥50% <15% Corrosive ≥50% ≥15% Non-Corrosive
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 2-(2-methoxyethoxy)ethyl methacrylate was not corrosive under the conditions of the OECD TG 431 in vitro study.
- Executive summary:
In accordance with OECD TG 431, using a three dimensional human epidermis model, following GLP conditions, the skin corrosion potential of 2-(2-methoxyethoxy)ethyl methacrylate is not corrosive.
