Description of key information
The skin sensitization potential of target chemical Sodium tris(1,2-naphthoquinone 1-oximato-O,O’)ferrate(1-) (CAS No: 16143-80-9) was assessedin various experimental studies which were conducted on guinea pigs and humans for target chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O’)ferrate(1-) (CAS No: 16143-80-9) andits closely related read across substancesBenzyl cinnamate (CAS No: 103-41-3)andBenzyl butyl phthalate (CAS No: 85-68-7). The predicted data usingQSAR toolboxhas also been compared with the experimental data.Based on the available data for the target and read across substances and applying the weight of evidence approach, it can be concluded that chemical Sodium tris(1,2-naphthoquinone 1-oximato-O,O’)ferrate(1-) (CAS No: 16143-80-9) is unable to cause skin sensitization and thus can be considered as not sensitizing. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.

Various studieshas been investigated for the test chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9)to observe the potential for skin sensitization to a greater or lesser extent. The studies are based on in vivo experiments in humans and guinea pigs for target chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) and its closely related read across substancesBenzyl cinnamate (CAS No: 103-41-3)andBenzyl butyl phthalate (CAS No: 85-68-7).The predicted data using the OECD QSAR toolbox has also been compared with the experimental data and summarized as below;
The skin sensitization potential of Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) was estimated by SSS (2017) using OECD QSAR toolbox v3.3 with log kow as the primary descriptor. The substance Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) is considered to be not sensitizing to the human skin.
The G. Klecak {Curr. Probl. Derm., vo1.14, pp.152-171 (Karger, Basel 1985)} conducted an Open Epicutaneous Test (OET) of read across chemical Benzyl cinnamate (CAS No: 103-41-3).During the study, thepretest was performed to determine the primary irritating threshold concentration of test substances at various concentrations (e.g, 100,30,10 and 3%). In this test, a single application of 0.025 ml of each test concentration was simultaneously performed on one of the areas measuring 2 cm2 of the flank skin previously clipped and marked with a circular stamp. Reactions are read 24 h after the application of the test material. On the basis of pretest, the concentration selected for sensitization test was 8 %.On day 1 during induction, 0.1 ml of the Benzyl cinnamate (CAS No: 103-41-3) was applied at concentrations of 8% in vehicle to an area measuring 8 cm2 on the clipped flank skin of the guinea pigs. The applications are repeated daily for 3 weeks or done 5 times weekly during 4 weeks, usually on the same skin sites. The application sites were left uncovered and the reactions, if continuous daily applications were performed, can be read 24 h after each application, or at the end of each week.To determine whether or not contact sensitization was induced, all groups of guinea pigs previously treated for 21 days, as well as 10 untreated, or only pretreated with the vehicle, controls are tested on days 21 and 35 on the contralateral flank with the test material. This test was performed by applying with a pipette 0.025 ml of chemical to skin areas measuring 2 cm2. The reactions were read after 24,48 and/or 72h.It was observed that none of the guinea pigs induced contact sensitization at challenge concentration of 8%.Thus the chemicalBenzyl cinnamate (CAS No: 103-41-3) was considered to be not sensitizing on skin of guinea pigs at concentration of 8% in an Open Epicutaneous Test (OET).
The above result was supported by experimental study conducted by Cosmetics Ingredient Review Panel (International Journal of Toxicology,Vol 11, Issue 1, pp. 1 – 23, 1992) for read across chemical Benzyl butyl phthalate (CAS No: 85-68-7) in 200 human volunteers for 24 hrs. Patches containing undiluted BBP were applied to the skin of 200 human volunteers for 24 hours, 3 times a week for 5 weeks. After a 2-week rest period when no patches were applied, human test subjects were rechallenged by applying patches containing BBP for 24 hours at previously untreated sites on the skin. During the induction and challenge phases, application sites were examined for signs of sensitization. No sign of sensitization was observed in any 200 human volunteers after 15 daily applications of a subsequent challenge with BBP. Therefore BBP was not considered to be a skin sensitizer in human repeated insult patch tests.
Based on the available data for thetarget chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) and its closely related read across substancesBenzyl cinnamate (CAS No: 103-41-3)andBenzyl butyl phthalate (CAS No: 85-68-7),it can be concluded thatchemical Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) is unable to cause skin sensitization and hence can be classified as non-skin sensitizer.
