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 hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0) is unable to cause skin irritation and thus considered as not irritating. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.

Skin irritation:

Various studieshas been investigated for the test chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  to observe the potential for dermal irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits for target chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  and its structurally similar read across substancesHexasodium;4-amino-3-[[4-[[4-chloro-6-(3-sulfonatoanilino)-1,3,5-triazin-2-yl]amino]-2-sulfonatophenyl]diazenyl]-6-[[4-[[4-chloro-6-(3-sulfonatoanilino)-1,3,5-triazin-2-yl]amino]-2 -sulfonatophenyl]hydrazinylidene]-5-oxonaphthalene-2,7-disulfonate(Reactive Green 19)[CAS:61931-49-5]and disodium 2,2'-ethene-1,2-diylbis{5-[(4-anilino-6-morpholin-4-yl-1,3,5-triazin-2-yl)amino]benzenesulfonate}) (CAS No: 16090-02-1).The predicted data using the OECD QSAR toolbox has also been compared with the experimental data and summarized as below;

 

 

In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the skin irritation potential was estimated for test chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0) .The chemical hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  is estimated to be not irritating to skin of rabbits.

 

The skin irritation study was conducted by U.S. Consumer Product Safety Commission {Fiber Reactive Dyes Toxicological Profiles December 1981,PB83-168732} for read across substance Hexasodium;4-amino-3-[[4-[[4-chloro-6-(3-sulfonatoanilino)-1,3,5-triazin-2-yl]amino]-2-sulfonatophenyl]diazenyl]-6-[[4-[[4-chloro-6-(3-sulfonatoanilino)-1,3,5-triazin-2-yl]amino]-2 -sulfonatophenyl]hydrazinylidene]-5-oxonaphthalene-2,7-disulfonate(Reactive Green 19)[CAS:61931-49-5] that supported the above mentioned result. Reactive Green 19 was applied to the skin of rabbits and observed for signs of irritation (dose, duration not mentioned). No skin irritation effects were observed when Reactive Green 19was applied to rabbit skin. Hence, Reactive Green 19 [CAS: 61931-49-5] can be considered to be not irritating to skin.

 

The above results were further supported by the experimental study summarized by OECD SIDS {SIDS Initial Assessment Report For SIAM 21- FLUORESCENT BRIGHTENER FWA-1; Washington, D.C; U.S.A., 18-20 October 2005} in rabbits for read across chemical disodium 2,2'-ethene-1,2-diylbis{5-[(4-anilino-6-morpholin-4-yl-1,3,5-triazin-2-yl)amino]benzenesulfonate})/ FLUORESCENT BRIGHTENER FWA-1 (CAS No: 16090-02-1). The test was performed on 3 male and 3 female New Zealand White or Russian breed rabbits weighing 1.7 to 3.0 kg. Before treatment, the entire back and the flank of each animal were shaved with an electric clipper and immediately before treatment start the shaven skin on the left flank was slightly scarified. 0.5 g FLUORESCENT BRIGHTENER FWA-1moistened with water was applied on both the flanks each animal under semi-occlusive conditions for 24 hours .Only results on intact skin areas at the 24-, 48- and 72 hour readings were used for assessment of skin irritation potential and were used in calculating the respective mean values. The scoring of skin reactions was performed 0 (immediately) 24, 48, and 72 hours.No signs of erythema or edema were observed. The mean scores for Erythema and edema were 0.0 at 24 and 48 hours (72 hours: not evaluated). Based on these observations, disodium 2,2'-ethene-1,2-diylbis{5-[(4-anilino-6-morpholin-4-yl-1,3,5-triazin-2-yl)amino]benzenesulfonate})/ FLUORESCENT BRIGHTENER FWA-1 (CAS No: 16090-02-1) can be considered to be not irritating to rabbit skin.

 

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 hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)    is unable to cause skin irritation and considered as not irritating. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.

 

 

Eye irritation:

In different studies,the test chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  has been investigated for potential for ocular irritationto a greater or lesser extent. The studies are based on in vivo experiments in rabbits for target chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  its structurally similar read across substances 1,5-Naphthalenedisulfonic acid, 2-[2-[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulfo-2-naphthalenyl]diazenyl]-, sodium salt (1:3) (REACTIVE ORANGE 4)[CAS: 12225-82-0] and Trisodium 7-[[4-chloro-6-[(4-sulphonatophenyl)amino]-1,3,5-triazin-2-yl]methylamino]-4-hydroxy-3-[(4-methoxy-2-sulphonatophenyl)azo]naphthalene-2-sulphonate(Reactive Red 33)[CAS: 12237-01-3].The predicted data using the OECD QSAR toolbox has also been compared with the experimental data and summarized as below;

 

 

In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the ocular irritation potential was estimated for test chemicalhexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0) .The chemical hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  is estimated to be not irritating to eye of rabbits.

 

Above result was further supported by the ocular irritation studies reported by U.S. Consumer Product Safety Commission {Fiber Reactive Dyes Toxicological Profiles December 1981,PB83-168732} for read across chemicals,1,5-Naphthalenedisulfonic acid, 2-[2-[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulfo-2-naphthalenyl]diazenyl]-, sodium salt (1:3) (REACTIVE ORANGE 4)[CAS: 12225-82-0] and Trisodium 7-[[4-chloro-6-[(4-sulphonatophenyl)amino]-1,3,5-triazin-2-yl]methylamino]-4-hydroxy-3-[(4-methoxy-2-sulphonatophenyl)azo]naphthalene-2-sulphonate(Reactive Red 33)[CAS: 12237-01-3]. Reactive Red 33 and REACTIVE ORANGE 4 were instilled in to the eyes of rabbits and observed for signs of irritation (dose, duration not mentioned). No irritation effects were observed when Reactive Red 33 and REACTIVE ORANGE 4were instilled into rabbit eyes. Hence, Reactive Red 33 and REACTIVE ORANGE 4 can be considered to be not irritating to eyes.

 

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 hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)    is unable to cause eye irritation and considered as not irritating. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.

Justification for classification or non-classification

The skin and eye irritation potential of test chemical hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  and its structurally similar read across substanceswere observed in various studies. The results obtained from these studies indicates that the chemical hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  is unlikely to cause skin and eye irritation. Hence hexasodium 4,4’-{ethene-1,2-diylbis[(3-sulfonato-4,1-phenylene)imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]}bis{6-[(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo- 1,6-dihydropyridin-3-yl)diazenyl]benzene-1,3-disulfonate} (CAS No: 68991-98-0)  can be classified under the category “Not Classified” for skin and eye as per CLP.
