*: Classification was done in accordance with EU Test Method B.46.
Substances are classified as "corrosive (R34)", if the cell viability of the EST 1000 is decreased by more than 50% after 3 min. of incubation to the test item, or if the cell viability is less than 15% after 60 min. of exposure to the test item.
Applicant's summary and conclusion
- Interpretation of results:
- other: non corrosive
- Executive summary:
The experiment was carried out according to OECD 431 and EU Test Method B.40 using commercially available reconstructed human epidermis (RHS) model EST-1000 (CellSystems, St.Katharinen, Germany).
Undiluted tetrachlorophthalic anhydride was applied topically to the RHS model, i.e. 50 µl per insert .
After an exposure period of 3 or 60 minutes, followed by a post-treatment incubation period of ca. 3 hours, the cell viability was measured to be 98.54 or 87.85 % respectivley, in the MTT (Methylthiazoletetrazolium) conversion assay.
The results of the concurrent negative control (NC, 0.9% NaCl) and positive controls demonstrated the viability (NC) and sensitivity (PC) of the test model.
Thus, the results show that tetrachlorophthalic anhydride should not be labelled as corrosive to skin
