Description of key information
Skin Irritation:
The dermal irritation potential of4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated using OECD QSAR toolbox v3.3 with logPow as the primary descriptor.
4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated to be not irritating to the skin of rabbits.
Based on the estimated results,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate can be considered to be not irritating to skin and can be classified under the category “Not Classified” as per CLP regulation.
Eye Irritation:
The ocular irritation potential of4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated using OECD QSAR toolbox v3.3 with logPow as the primary descriptor.
4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated to be not irritating to the eyes of New Zealand White rabbits.
Based on the estimated results,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate 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,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate has 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 chemical and its structurally similar read across substance bis[2-(2-butoxyethoxy)ethyl] adipate [CAS: 141-13-7 ]and functionally similar read across substance Sodium formate[CAS : 141-53-7]. 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 for4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate. 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated to be not irritating to the skin of rabbits.
This result is supported by the experimental study summarized in International Journal of Toxicology, 35(2_suppl), pp.41S-54S; 2016; for the functionallysimilar read across substance Sodium formate[CAS : 141-53-7]. The study was performed on 4 rabbits (3 male, 1 female). Sodium formate(in physiological saline) was applied to 4 abraded sites per rabbit (left, right and front, back) under an occlusive patch for 24 hours. The reactions were observed and scored at 72 hours after patch removal. Skin irritation was not observed in any of the rabbits after 72 hours of patch removal.
Hence, Sodium formate can be considered to be not irritating to skin.
The above results are further supported by the experimental study summarized in Robust summaries for bis[2-(2-butoxyethoxy)ethyl] adipate, submitted by PCA Services Inc, USA, 2011; for thestructurally similar read across substance bis[2-(2-butoxyethoxy)ethyl] adipate [CAS: 141-13-7].The study was conducted on6 New Zealand White rabbits according to EPA OTS 798.4470 (Acute Dermal Irritation) Guidelines.The hair of the mid-dorsal area of the trunk of each rabbit, between scapulae and pelvis, was shaved using an Oster small animal clipper with surgical head (#40). Care was taken to avoid abrasion of the skin during clipping. Prior to dose application, animals were placed into wooden restrainers. One (1) test site of approximately six (6) square centimeters was chosen on each animal. A single application of 0.5 ml of,bis[2-(2 -butoxyethoxy)ethyl] adipate was made to each site after which the area was covered with a two and one-half (2.5) centimeter square surgical gauze pad (Johnson & Johnson). This was held in place with three (3) inch Johnson & Johnson hypo-allergenic cloth tape, semi-occlusively. Animals were collared for the duration of the exposure to preclude access to the site. Wrappings and test article were removed after four (4) hours following application. Remaining test article was gently washed from the skin with water and paper towels. Each site was then individually examined and scored at 30 and 60 minutes following unwrapping for erythema and edema according to Draize. Observations continued at 24, 48 and 72 hours. Mean scores from the 24 and 72 hour reading were averaged to determine the primary irritation index. The animals did not exhibit any abnormal clinical signs for the duration of the study. The Primary Dermal Irritation Index (PDII) after 24 and 72 hours was 0.65.
Based on the PDII scores, bis[2-(2-butoxyethoxy)ethyl] adipate was assessed as minimal irritant to rabbit skin. Since the effects observed where completely reversible within 7 days of observation,bis[2-(2-butoxyethoxy)ethyl] adipate can be considered as not irritating to skin.
Based on the available data for the target as well as read across substances and applying the weight of evidence approach,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was not irritating to skin.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”
Eye Irritation:
In different studies,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate has been investigated for potential for ocular irritation to a greater or lesser extent. The studies are based on in vivo experiments in rabbits along with predicted data for target chemical and its structurally similar read across substance bis[2-(2-butoxyethoxy)ethyl] adipate [CAS: 141-13-7] and functionally similar read across substance Sodium formate[CAS : 141-53-7]. 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 for4-oxo-2 -sulfonato-5,8,11,14-tetraoxahexacosan-1-oate. 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was estimated to be not irritating to the eyes of new Zealand White rabbits.
This result is supported by the experimental study summarized in International Journal of Toxicology, 35(2_suppl), pp.41S-54S; 2016; for the functionallysimilar read across substance Sodium formate [CAS : 141-53-7]. The study was performed on 6 New Zealand White rabbits (3 male, 3 female).Sodium formate (0.1 ml, powder) was instilled in the lower conjunctival sac of the left eye of the rabbits. The right eye remained untreated and served as control. Reactions were scored at 1, 24, 48 and 72 hours, and 7, 10, 14 and 17 days post-instillation. Moderate to severe conjunctival irritation was observed in all rabbits and conjunctival necrosis was observed in 4 of 6 rabbits. All reactions had cleared by 17 days.
Since the effects are fully reversible in 17 days, hence Sodium formate can be considered to be not irritating to eyes.
The above results are further supported by the experimental study summarized in Robust summaries for bis[2-(2-butoxyethoxy)ethyl] adipate, submitted by PCA Services Inc, USA, 2011; for thestructurally similar read across substance bis[2-(2-butoxyethoxy)ethyl] adipate [CAS: 141-13-7]. The study was conducted on6 New Zealand White rabbits according to EPAOTS 798.4500 (Acute Eye Irritation) guidelines. A dose of 0.1 mL (1/10 milliliter) of the test article was applied to one eye of 6 New Zealand White rabbits (3 male and 3 female) by gently pulling the lower lid away from the eyeball to form a cup into which the test article was dropped. The eyelids were then gently held together for one (1) second. The untreated eye served as control. The eyes remained unwashed. The Average Scores after 72 hours was 0.0
According to 40 CFR 798.4500 and under the conditions of this test, bis[2-(2-butoxyethoxy)ethyl] adipate elicited minimal irritation which was reversible within 72 hours (3 days). No fluorescein retention was recorded at any interval. Since the average scores were 0 after 72 hours and the effects were fully reversible in 72 hours, bis[2-(2 -butoxyethoxy)ethyl] adipate can be considered not irritating to eyes.
Based on the available data for the target as well as read across substances and applying the weight of evidence approach,4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate was not irritating to eyes.Comparing the above annotations with the criteria of CLP regulation, test chemical can be classified under the category “Not Classified”
Justification for classification or non-classification
Available data for 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate suggests that it is not likely to cause any irritation to eyes and skin.
4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate can be classified under the category “Not Classified” as per CLP regulation.
