Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was not characterised by a significant impact on cell viability after the 3 min and after the 60 min period.
Thus, it should not be labelled as corrosive to skin. - Executive summary:
This study for predicting non-specific, corrosive potentials of compounds by using reconstructed human skin (RHS) was performed in 2008. The experiment was carried out on a reconstructed human epidermis EST-1000 (CellSystems, St. Katharinen, Germany) for detection of topically applied skin corrosives with the test item.
A 100% concentration was tested on the skin/epidermal equivalents in triplicate. For the determination of time related cytotoxic effects the incubation periods were 3 min and 60 min, respectively. Thus the study was conducted in accordance with the OECD 431 guideline draft as well as with an EC draft guideline (amending Council Directive 67/548/EEC, B.40 Skin corrosion) using the test item concentrations and incubation periods recommended there.
The test item was applied at a 100% concentration, i.e. 25 mg per insert. The MTT (Methylthiazoletetrazolium) method has determined the following values of viability after 3 min. or after 60 min. of incubation: 100.83% and 94.53%, respectively.
Thus, the results show that no corrosive property of the test item was determined by the assay used.
