REMOVAL OF TEST MATERIAL AND CONTROLS
-Volume and number of washing steps: The tissue inserts were filled and emptied 15 times using sterile CMF-DPBS. For the control articles where a mesh was used, the mesh was carefully removed with forceps (if necessary) after the 5th rinse. After the removal of the mesh, the rinsing procedure of the tissue continued for 10 times. After the 15th rinse, the cell culture inserts were completely submerged, gently swirled, and rinse media dumped into a beaker containing 150 mL of CMF-DPBS three times. The tissues were rinsed once more on the inside and outside of the cell culture insert with sterile CMF-DPBS from a wash bottle, and the excess CMF-DPBS was decanted.
- Observable damage in the tissue due to washing: none reported
- Modifications to validated SOP: none

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was predicted to be a non-irritant (mean viability was 101.0%).
- Executive summary:
The purpose of this study was to evaluate the skin irritation potential of the test substance. The skin irritation potential was evaluated based upon measuring the relative conversion of MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) in the test substance-treated tissues after exposure to the test article for a 60-minute exposure period, followed by a 42-hour post-exposure expression period. Skin irritation potential of the test substance was predicted if the relative viability was less than or equal to 50%. The protocol was based upon the OECD guideline, “In Vitro Skin Irritation: Reconstructed Human Epidermis Test Method” (TG 439). The test article was not observed to directly reduce MTT in the absence of viable cells. The mean viability of the test substance was 101.0%, based on this result, the test substance is predicted to be a non-irritant.
