According to TG 439 where a test chemical is found to be non-corrosive in test TG 431 and where the tissue viability after exposure and post-treatment is <50%, the test chemical is considered to be irritant in accordance with UN GHS Category 2. - Executive summary:
The objective was to assess the potential for corrosive activity and skin irritation of Vibracolor ruby red. Using the currently available methods a single in vitro assay may not always be sufficient to cover the full range of skin irritating/corrosion potential. Therefore, two in vitro assays were part of this in vitro skin irritation and corrosion test strategy: The Skin Corrosion Test (SCT) (OECD TG 431) and Skin Irritation Test (SIT) (OECD TG 439).
The tests were performed according to the test guidelines and as the test chemical is coloured and to avoid colour interferences with the test methods colour controls and freeze-killed control tissues were included in the study as described in the study guidelines.
In the skin corrosion test (TG 431), after 3 minutes the results of the color control (CC) tissues indicate interference due to the color of the test substance (mean value 3.7% of NC). The results of the KC tissues did not indicate an increased MTT reduction. Thus for the test substance the final mean viability is given after CC correction and was 93.9%; a non-corrosive prediction. After a 1 hour exposure period, the results of the color control (CC) tissues indicate interference due to the color of the test substance (mean value 17.2% ofNC).The results of the KG tissues indicate an increased MTT reduction (mean viability 0.2% of NC). Thus for the test substance the final mean viability is given after CC and KC correction and is 75.1%; a non-corrosive prediction.
In the skin irrtation test (TG 439), although red discoloration of the tissues was observed, no extraction of the test substance into the isopropanol was obtained.The results of the KC tissues did not indicate an increased MTT reduction. Thus for the test substance the final mean viability is given without CC and KC correction and is 45.5%. As this is less than the criteria of less than or equal to 50% the results are indicative of skin irritation.
According to TG 439 where a test chemical is found to be non-corrosive in test TG 431 and where the tissue viability after exposure and post-treatment is <50%, the test chemical is considered to be irritant in accordance with UN GHS Category 2.

Reference
Applying the criteria of the OECD 437 fortheassessment of the BCOP test results,theIVISscores ofthe testsubstance of 0.0 (50%testsubstance preparation) or 1.9 (5% test substance preparation) would classify it as a substance that does not cause eye irritation or serious eye damage.However,the Guideline also states,that due to limited accuracy of the BCOP test to correctlyidentifysubstances that do not require classification for eyeirritationor serious eye damage,thistestmethodshould not bethe firstchoice toinitiatea bottom-up approach. Based onthisstatement and the experience ofthe testfacility,testsubstances leading to IVIS <3 are generally examinedin the EpiOculartest as well.In thecurrent case, the EpiOculartestwas positive and thetestsubstance was assessedtobe irritating.
