Endpoint summary

Description of key information

Skin Irritation:

The dermal irritation potential of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated using OECD QSAR toolbox v3.3 with logPow as the primary descriptor.

Interpretation of results:

other: not irritating

Conclusions:

2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated to be not irritating to the skin of New Zealand White rabbits.

Executive summary:

The dermal irritation potential of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated using OECD QSAR toolbox v3.3 with logPow as the primary descriptor.

2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated to be not irritating to the skin of New Zealand White rabbits.

Based on the estimated results, 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate can be considered to be not irritating to skin and can be classified under the category “Not Classified” as per CLP regulation.

other: not irritating

Conclusions:

2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated to be not irritating to the eyes of New Zealand White rabbits.

Executive summary:

The ocular irritation potential of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated using OECD QSAR toolbox v3.3 with logPow as the primary descriptor.

2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was estimated to be not irritating to the eyes of New Zealand White rabbits.

Based on the estimated results, 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate can be considered to be not irritating to eyes and can be classified under the category “Not Classified” as per CLP regulation.

Additional information

Skin Irritation:

In different studies, 2,2'-[(3-acetamidophenyl)imino]diethyl diacetatehas been investigated for potential for dermal irritation to a greater or lesser extent. The studies are based on in vivo and in vitro experiments along with predicted data for target chemical and its closely related read across substances, diethyl malonate [CAS: 105-53-3] and Ethyl acetate [CAS: 141-78-6]. The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.

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 for2,2'-[(3-acetamidophenyl)imino]diethyl diacetate. It was estimated that2,2'-[(3-acetamidophenyl)imino]diethyl diacetatewas not irritating to skin of New Zealand White rabbits.

Skin irritation effects were also estimated by four different models i.e, Battery, Leadscope, SciQSAR and CASE Ultra used within Danish QSAR database for2,2'-[(3-acetamidophenyl)imino]diethyl diacetate.Based on estimation, no severe skin irritation effects were known when 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate was exposed to rabbit skin.Hence,2,2'-[(3 -acetamidophenyl)imino]diethyl diacetate can be considered to be not irritating to skin.

Both the estimated results, indicate the possibility of 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate being not irritating to skin.

These results are further supported by the experimental study summarized in Food and Cosmetics Toxicology, Volume 14, Supplement, 1976, Pages 745-746; for the closely related read across substance,diethyl malonate [CAS: 105-53-3]. Diethyl malonate was tested 4% in petrolatum in 48 hours closed patch test on human volunteers. Diethyl malonate was not irritating to human skin after 48 hours exposure.

These results are also supported by the experimental study summarized in Food and Cosmetics Toxicology, 1979, Pages 341–342; for the closely related read across substance, Ethyl acetate [CAS: 141-78-6]. Ethyl acetate was tested 10% in petrolatum in 48 hours closed patch test on 25 human volunteers. Ethyl acetate was not irritating to human skin after 48 hours exposure.

Based on the available data for the target as well as it read across substances;and applying the weight of evidence approach, it can be concluded that2,2'-[(3-acetamidophenyl)imino]diethyl diacetatewas not irritating to skin.Comparing the above annotations with the criteria of CLP regulation,2,2'-[(3-acetamidophenyl)imino]diethyl diacetate can be classified under the category “Not Classified”.

Eye Irritation:

In different studies, 2,2'-[(3-acetamidophenyl)imino]diethyl diacetatehas been investigated for potential for ocular irritation to a greater or lesser extent. The studies are based on in vivo and in vitro experiments along with predicted data for target chemical and its closely related read across substances, Ethylene glycol diacetate[CAS: 111-55-7], Dimethyl glutarate [CAS: 1119-40-0] and Dimethyl adipate [CAS: 627-93-0].The predicted data using the OECD QSAR toolbox has also been compared with the experimental data.

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 for2,2'-[(3-acetamidophenyl)imino]diethyl diacetate. It was estimated that 2,2'-[(3-acetamidophenyl)imino]diethyl diacetatewas not irritating to eyes of New Zealand White rabbits.

This result is supported by the experimental study summarized in Hazardous Substance Databank (HSDB), U.S National Library of Medicine, last updated 2003; for the closely related read across substance,Ethylene glycol diacetate[CAS: 111-55-7]. Ethylene glycol acetate was instilled into rabbit eyes and observed for signs of irritation till 24 hours. The degree of eye injury observed after 24 hours was rated on a scale of 1 to 10. Most severe injuries were rated 10.Primary Irritation score after 24 hours for Ethylene glycol acetate was Grade 1.

Based on the ratings, ethylene glycol acetate can be considered not irritating to rabbit eyes.

These results are further supported by the experimental study summarized in The MAK Collection for Occupational Health and Safety. 1-32; 2012; for the closely related read across substance, Dimethyl glutarate [CAS: 1119-40-0]. 0.1 ml dimethyl glutarate was instilled into the conjunctival sac of 6 rabbits and observed for signs of irritation till 7 days.Mild to moderate irritant, conjunctival redness & Swelling (6), tear flow (6), cornea: opacities or matt surface (3) ulceration (4), Iris changes (2) were observed in the treated animals. These effects were reversible in 7 days.

Since the observed effects were reversible in 7 days, dimethyl glutarate can be considered not irritating to rabbit eyes.

These results are further supported by the experimental study summarized in The MAK Collection for Occupational Health and Safety. 1-32; 2012; for the closely related read across substance, adipate [CAS: 627-93-0]. 0.1 ml dimethyl adipate was instilled into the conjunctival sac of 6 rabbits and observed for signs of irritation till 7 days. Mild to moderate irritant, conjunctival redness & Swelling (6), tear flow (6), corneal opacities (4), iris changes (5)were observed in the treated animals. These effects were reversible in 7 days. Since the observed effects were reversible in 7 days, dimethyl adipate can be considered not irritating to rabbit eyes.

Based on the available data for the target as well as it read across substances;and applying the weight of evidence approach, it can be concluded that2,2'-[(3-acetamidophenyl)imino]diethyl diacetatewas not irritating to skin.Comparing the above annotations with the criteria of CLP regulation,2,2'-[(3-acetamidophenyl)imino]diethyl diacetate can be classified under the category “Not Classified”.

Justification for classification or non-classification

Based on the available information, 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate is not likely to cause any irritation to eyes and skin.

Hence,2,2'-[(3-acetamidophenyl)imino]diethyl diacetate can be classified under the category “Not Classified” as per CLP regulation.
