NUMBER OF INDEPENDENT TESTING RUNS / EXPERIMENTS TO DERIVE FINAL PREDICTION: 3 per test article or control
PREDICTION MODEL / DECISION CRITERIA
A test item is considered irritant in the skin irritation test if:
The relative mean tissue viability of three individual tissues after 15 minutes of exposure to the test item and 42 hours of post incubation is ≤ 50% of the mean viability of the negativecontrols.
A test item is considered non-irritant in the in vitro skin irritation test if:
The relative mean tissue viability of three individual tissues after 15 minutes of exposure to the test item and 42 hours of post incubation is > 50% of the mean viability of the negative controls.
The in vitro skin irritation test is considered acceptable if it meets the following criteria:
a) The absolute mean OD570 (optical density at 570 nm) of the three tissues of the negative control should reasonably be within the laboratory historical control data range and the Standard Deviation value (SD) of the % viability should be less than or equal to 18.
b) The mean relative tissue viability of the positive control should be less than or equal to 40% relative to the negative control and the Standard Deviation value (SD) of the % viability should be less than or equal to 18.
c) The SD calculated from individual % tissue viabilities of the three identically treated replicates should be less than or equal to 18. - Control samples:

Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- Based on the results of the study, test article is equivocal in the in vitro skin irritation test under the experimental conditions described. The test was concluded to be valid, however the test item is not suitable for the assay. In the absence of a conclusive finding for skin irritation, a Skin 2 classification is assigned.
- Executive summary:
The dermal irritation potential of the test article was evaluated in an in vitro reconstructed epidermal model. The study was conducted in compliance with OECD GLP (1997) according to OECD Test Guideline 439 (2015). The undiluted test article (25 uL) was applied to the tissues (n=3) and the tissues were incubated for 15 minutes at room temperature. Positive (5% Sodium dodecyl sulfate (SDS) in phosphate buffered saline (PBS)) and negative (PBS) controls were tested in parallel. Following exposure, the tissues were washed to removed the test article and controls and incubated for 42 hours at 37 C. Following the post-exposure incubation, tissue viability was determined using the MTT assay. Test article tissue viability was compared to negative control tissues. In the fist assay, the mean test article-treated tissue viability was 46%. The standard deviation value of the percentage viability was 44% and the results of the individual tissues were in 2 different categories (96%, 26% and 15%). To gain more information the assay was repeated. In the second assay, the mean test article-treated tissue viability was 73%. However, the standard deviation was 41% and the individual results were again divided over two categories (31%, 113% and 75%). Based on the results of the study, test article is equivocal in the in vitro skin irritation test under the experimental conditions described. The test was concluded to be valid, however the test item is not suitable for the assay. In the absence of a conclusive finding for skin irritation, a Skin 2 classification is assigned.
