Additional information

Acute oral toxicity:

In different studies, disodium 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate has been investigated for acute oral toxicity to a greater or lesser extent. Often are the studies based on in vivo estimated and experiments in rodents, i.e. most commonly in rats for disodium 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate along with the study available on structurally similar read across substance across substance Sodium 1-methoxycarbonylpentadecane-2-sulfonate (CAS: 4016-24-4)The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.

In prediction done by SSS (2017) using Danish QSAR (EPA Model), 50 % mortality observed at 17000 mg/kg bw . Therefore, estimated LD50 was considered to be 170000 mg/kg bw when rat were treated disodium 4-oxo-2-sulfonato-5, 8, 11, 14-tetraoxahexacosan-1-oate orally.   

In another prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate. The LD50 was estimated to be 2074 mg/kg bw when Wistar female rats were orally exposed with 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate.

Also it is further supported experimental data by J-CHECK (Ministry of Health, Labour and Welfare", "Ministry of the Environment" and "National Institute of Technology and Evaluation, 2010), on structurally similar read across substance Sodium 1-methoxycarbonylpentadecane-2-sulfonate (CAS: 4016-24-4), Crj: CD(SD)IGS male and female rats were treated Sodium 1-methoxycarbonylpentadecane-2-sulfonate in the concentration of 0, 786, 983, 1229, 1536, 1920, 2400 mg/kg orally by gavage in Olive oil. Deaths was observed 6 to 24 hours after administration in male rats at 983, 1229, 1536, 1920, 2400 mg/kg and in female rats at 1536, 1920, 2400 mg/kg. Decreased locomotor activity, ptosis, diarrhea, soiling of the perineal region and piloerection were observed in treated groups. Most clinical signs in the survivors showed a tendency for recovery on the day following administration and all had disappeared after 6 days. In addition, Dose dependent decrease in body weights were observed in treated male and female rats. However, a tendency for recovery was noted 3 days after the administration. Distention of the stomach with a watery content was observed in most of the animals which died. Therefore, estimated LD50 was considered to be 170000 mg/kg bw when rat were treated disodium 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate orally.   

Thus based on the above studies and predictions on 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate and its read across substances, it can be concluded that most of the LD50 value is greater than 2000 mg/kg bw. Thus comparing this value with the criteria of CLP regulation, 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate can be Not classified for acute oral toxicity.

Justification for classification or non-classification

Thus, based on the above studies and predictions on 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate and its read across substances, it can be concluded that most of the LD50 value is greater than 2000 mg/kg bw. Thus comparing this value with the criteria of CLP regulation, 4-oxo-2-sulfonato-5,8,11,14-tetraoxahexacosan-1-oate can be Not classified for acute oral toxicity.
