Skin Irritation:
In different studies,Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonatehas been investigated for potential for dermal irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits along with predicted data for target chemicaland its structurally similar read across chemicals,Copper,[tetrahydrogen-3,3'-[(3,3'-dihydroxy-4,4'-biphenylylene)bis(azo)]bis[5-amino-4-hydroxy-2,7-naphthalenedisulfonato](4-)]di-,tetrasodium salt (7CI)(C.I Direct Blue 218)[CAS:28407-37-6], 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] and trisodium 5-amino-3-[(E)-2-(4-{4-[(E)-2-(7-amino-1-hydroxy-3-sulfonatonaphthalen-2-yl)diazen-1-yl]phenyl}phenyl)diazen-1-yl]-4-hydroxynaphthalene-2,7-disulfonate(Chlorazol Black BH)[CAS: 2429-73-4].The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.
In a prediction done by SSS (2018) using the OECD QSAR toolbox v3.4 with log kow as the primary descriptor, the skin irritation potential was estimated for Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate. Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate was estimated to be not irritating to rabbit skin.
A study was performed (Hazardous Substances Databank [HSDB], U.S National Library of Medicine, last updated 2003) in rabbits to determine the dermal irritation potential of the structurally similar read across chemicals,Copper,[tetrahydrogen-3,3'-[(3,3'-dihydroxy-4,4'-biphenylylene)bis(azo)]bis[5-amino-4-hydroxy-2,7-naphthalenedisulfonato](4-)]di-,tetrasodium salt (7CI)(C.I Direct Blue 218)[CAS:28407-37-6]. The study was conducted as per 16 CFR 1500.41 &16 CFR 1500.3 Guidelines.6 New Zealand white rabbits were used for the study. After at least seven days of equilibration, the back and sides of each rabbit were clipped free of fur with an electric clipper. Rabbits with dermal lesions or irritation were replaced. One day after clipping, the left side of the spinal column was abraded (minor incisions which did not disturb the derma or produce bleeding). 0.5 g of the test material was applied to the intact and abraded skin of the back of the rabbits. The material was covered with dry surgical gauze, one inch square, two layers thick. The patches were secured with adhesive tape; the trunk was wrapped with impervious material. After 24 hours, the patches were removed. The dermal reactions were scored by the Draize technique at 24 and 72 hours. The primary dermal index was calculated.
No signs of erythema or edema were observed on the intact and abraded skin of the 6 rabbits after 24 and 72 hours of patch removal.
The Primary Irritation Index was calculated to be 0.0.
Based on the scores and observations, it was concluded that C.I. Direct Blue 218 [CAS: 28407-37-6] was not irritating to skin.
These results are supported by the experimental study summarized in Fiber Reactive Dyes Toxicological Profiles December 1981,PB83-168732; for the structurally similar read across chemical,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]. 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 whenReactive Green 19was applied to rabbit skin.
Hence,Reactive Green 19can be considered to be not irritating to skin.
These results are further supported by the study summarized in OTS0215154, NTRL report, last updated 1983; for the structurally similar read across chemical,trisodium 5-amino-3-[(E)-2 -(4-{4-[(E)-2-(7-amino-1-hydroxy-3-sulfonatonaphthalen-2-yl)diazen-1-yl]phenyl}phenyl)diazen-1-yl]-4-hydroxynaphthalene-2,7 -disulfonate(Chlorazol Black BH)[CAS: 2429-73-4].6 New Zealand white rabbits were used for the study. The backs of the animals were clipped free of hair and the skin examined before testing. Only those animals without skin defects or irritation were used. Abrasions (minor incisions through the stratum corneum, but not sufficiently deep to disturb the derma) were made on one area of the backs while other area was left intact. The animals were immobilized in animal holders. 0.5 gm of a 50% w/v aqueous dilution of Chlorazol Black BH was applied under each of two one-inch square gauze patches to the prepared areas on the back of the animals. After the patches had been secured by adhesive tape, the entire trunk of each animal was wrapped with a plastic binder to keep the material in position and in contact with the skin for 24 hours. Following the 24 hours of exposure, the patches were removed; any remaining material was washed off the treated areas. The test sites were observed at 24 and 72 hours after removal of patches. The dermal reactions were scored by the Draize technique at 24, 72 hours and the Primary Irritation Index (PII) was calculated. The average values for erythema and eschar formation at 24 hours and 72 hours for the intact skin areas of exposure were added to the average values of the abraded skin areas of exposure at 24 hours and 72 hours (four values). Similarly, the average values for edema formation at 24 hours and at 72 hours for the intact and abraded skin areas of exposure were added (four values). The Primary Irritation Index is the total of the eight average values divided by four. According to the F.H.S.A method of testing, a Primary Irritant is a substance which produces a skin reaction resulting in a score of five or greater.
Chlorazol Black BH [CAS: 2429-73-4] when applied as a 50% w/v suspension with deionized water to the intact and abraded skin of New Zealand albino rabbits produced mild skin damage (abraded skin only) which persisted till 72 hours. No gross signs of local irritation were observed in the intact skin throughout the study. A deep bluish- purple was present at the abrasion of each animal at each reading; a light stain of similar color of the intact skin was observed at the 24-hour reading (all animals) and 48 hour reading (4 animals).
The Primary Irritation Index was calculated to be 0.50.According to F.H.S.A method of testing, Chlorazol Black BH [CAS: 2429-73-4] was considered to be not irritating to skin.
Based on the available data for the target and applying the weight of evidence approach, Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate was considered not irritating to skin.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”.

The studies are based on in vivo experiments in rabbits along with predicted data for target chemicaland its structurally similar 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]. The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.
In a prediction done by SSS (2018) using the OECD QSAR toolbox v3.4 with log kow as the primary descriptor, the eye irritation potential was estimated forOctasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate. Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate was estimated to be not irritating to New Zealand White rabbit eyes.
This result is supported by the experimental studies summarized in Fiber Reactive Dyes Toxicological Profiles December 1981,PB83-168732; for the structurally similar 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 4were 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 andREACTIVE ORANGE 4can be considered to be not irritating to eyes.
Based on the available data for the target and applying the weight of evidence approach, Octasodium 2,2'-[(2,2'-disulphonato[1,1'-biphenyl]-4,4'-diyl)bis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino(1-hydroxy-3-sulphonatonaphthalene-6,2-diyl)azo]] bisnaphthalene-1,5-disulphonate was considered not irritating to eyes.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”.
