Results and discussion
Any other information on results incl. tables
This in vitro study was performed to assess the irritation potential of GR-50-0091 by means of the Human Skin Model Test according to OECD TG 439. Three tissues of the human skin model EpiSkin™ were treated with the test item, the negative or the positive control for 15 minutes. 10 μL of the test item were applied to each tissue, spread to match the tissue size. 10 μL of either the negative control (deionised water) or the positive control (5% Sodium lauryl sulfate) were applied to each tissue. After treatment with the negative control the absorbance values were well within the required acceptability criterion of mean OD 0.6 till ≤ 1.5 for the 15 minutes treatment interval thus showing the quality of the tissues. Treatment with the positive control induced a sufficient decrease in the relative absorbance as compared to the negative control for the 15 minutes treatment interval thus ensuring the validity of the test system. After treatment with the test item GR-50-0091 the relative absorbance values decreased to 7.6%. This value is well below the threshold for irritancy of ≤ 50%. Therefore, the test item is considered to possess an irritant potential. In conclusion, it can be stated that in this study and under the experimental conditions reported, the test item GR-50-0091 is irritant to skin according to UN GHS (9) and EU CLP regulation (10)
