Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on these results, the OECD 442E and OECD 497 prediction models, the test item “Ozonia 3000 Sunflower (Ozonized Sunflower Seed Oil)” was shown to be negative and demonstrated in vitro non-sensitising potential under the experimental conditions of the human Cell Line activation Test.
- Executive summary:
In the course of this study the skin sensitisation potential of “Ozonia 3000 Sunflower (Ozonized Sunflower Seed Oil)” was examined.
The extent of cytotoxicity induced on THP-1 cells by the test item was studied in two runs of the dose finding test. The maximal final concentrations used on the plates for the test item previously dissolved in DMSO were 1000.0 μg/mL (first run) and 1001.0 μg/mL (second run). Since no cytotoxicity was observed in the first run, the same concentration range was used in the second run and start from the highest allowed concentration (1000 μg/mL). Since in the second run no cytotoxicity was observed either, no CV75 value was calculated. Based on the results of two runs of the dose finding test, eight doses between 1000.0 μg/mL – 279.1 μg/mL (nominal concentrations) were used for the main test in two independent runs. Both runs were concluded valid.
The increase in CD86 marker expression (RFI) was lower than 150 % at all tested doses (with > 50 % of cell viability) compared to the respective negative controls in both valid runs. Moreover, according to the OECD Test Guideline 497 prediction model, the increase in CD86 marker expression (RFI) was below the borderline range (122-184 %) at all tested concentrations compared to the respective negative controls in all independent runs. Also, no cytotoxicity was observed at any tested concentrations in either independent run. Based on the two valid concordant negative runs, CD86 marker expression was concluded to be negative. Effective concentration for CD86 expression (EC150) was not determined, since a negative result was obtained.
The increase in CD54 marker expression (RFI) was lower than 200 % at all tested concentrations compared to the respective negative controls in both independent valid runs. Moreover, according to the OECD Test Guideline 497 prediction model, the increase in CD54 marker expression (RFI) was below the borderline range (157-255 %) at all tested concentrations compared to the respective negative controls in both independent runs. Furthermore, no cytotoxicity was observed at any tested concentrations in either independent run.
Based on the two valid concordant negative runs, CD54 marker expression was concluded to be negative. Effective concentration for CD54 expression (EC200) was not determined, since a negative result was obtained.
Since both CD86 and CD54 marker expressions gave negative results, the overall h-CLAT prediction was also concluded to be negative.
