Additional information

Skin irritation:

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 dermal irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits 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 substances Benzyl 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 COMMISSION OF THEEUROPEAN COMMUNITIES reported skin irritation study for target chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) in rabbits. When 500 mg of 50% aqueous suspension or 500mg (0.5g) of undiluted Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) was applied on intact or abraded skin of each rabbit, none of the treated rabbits showed positive skin reaction. Hence Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) was considered to benotirritating to the skin of rabbit.

 

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 chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9).The test Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) is estimated to be not irritating to skin of New Zealand White Rabbits.

 

The Primary Skin irritation study was conducted by D.L.J. Opdyke (Food and Cosmetics Toxicology 1979, Pages 132–133) for read across chemical Benzyl cinnamate (CAS No: 103-41-3) on 25 human subjects that supported the abov mentioned results for target chemical. Each subject was treated with 8% of Benzyl cinnamate (CAS No: 103-41-3) in petrolatum dermally for 48 hours under a closed path patch.Since no known signs of irritation was observed, the chemicalBenzyl cinnamate (CAS No: 103-41-3)was considered to be not irritating to theskin of human subjects.

 

The above results were supported by dermal irritation study conducted by Cosmetics Ingredient Review Panel (International Journal of Toxicology,Vol 11, Issue 1, pp. 1 – 23, 1992) of read across chemical Benzyl butyl phthalate (CAS No: 85-68-7) in 6 New Zealand White rabbits. Undiluted Benzyl Butyl Phthlate, 0.5 ml, was applied to the intact and abraded skin of rabbits and effects were observed for 24 h. There was practically no irritation to the rabbit skin exposed to Benzyl butyl phthalate for 24 h. Hence, Benzyl butyl phthalate can be considered as not irritating to New Zealand White rabbit skin.

 

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 substances Benzyl 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 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 chemical Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9)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 chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) and its closely related read across substanceBenzyl 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 COMMISSION OF THEEUROPEAN COMMUNITIES reported an eye irritation study for target chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) in rabbits. When 0.1 mL of 33% suspension in saline, or 100mg (0.1g) of undiluted Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) was installed into one of the eye of each rabbit, the animals did not produce any ocular lesions. Hence Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) was considered to benotirritating to the eyes of rabbit.

 

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 chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9).The test Sodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) is estimated to be not irritating to the eye of rabbits.

 

The above results were supported by an eye irritation 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).The ocular irritation potential ofBenzyl butyl phthalate was evaluated in 6 New Zealand White rabbits.0.1ml of undiluted Benzyl butyl phthalate was instilled into the conjunctival sac of the eyes of the 6 rabbits and effects were observed till 48 hours.Under the conditions of the study, benzyl butyl phthalate showed slight irritation in rabbit eyes which subsided completely before 48 hours.Hence, Benzyl butyl phthalate can be considered as not irritating to New Zealand White rabbit eyes.

 

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 substances Benzyl 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 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 chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) and its closely relatedread across substances were observed in various studies. The results obtained from these studies indicates that the chemicalSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) is not likely to cause skin and eye irritation. HenceSodium tris(1,2-naphthoquinone 1-oximato-O,O')ferrate(1-) (CAS No: 16143-80-9) can be classified under the category “Not Classified” for skin and eye as per CLP.
