Additional information

Acute oral toxicity

In different studies, sodium 2-[(1-oxododecyl)amino]ethanesulphonate (70609-66-4) has been investigated for acute oral toxicity to a greater or lesser extent. Often are the studies based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (70609-66-4). The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.

In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (70609-66-4),LD50 was estimated to be 4940mg/kg bw, when male and female rats were exposed with sodium 2-[(1-oxododecyl) amino]ethanesulphonate (70609-66-4)orally.

Also it is further supported by experimental study given by Cosmetic Ingredient Review Expert Panel (Cosmetic Ingredient Review Expert Panel, 2016) on structurally similar read across substance sodium N-methyltaurinate (4316-74-9).Acute oral toxicity study was done in wistar rats using sodium N-methyltaurinate (4316-74-9) in dose concentration 4000, 4500, 4750, 5000, 6300 mg/kg in water given by oral route. No mortality was observed at dose 4670mg/kg bw but Necropsies showed unspecified changes to the intestines/ gastrointestinal tract, especially in the rats that died before the end of the experiment HenceLD50 was considered to be >4670mg/kgbody weight. When wistar rats was treated with sodium N-methyltaurinate (4316-74-9)orally.

Also it is further supported by experimental study given by U.S .National library of medicine (ChemID plus A TOXNET DATABASE.2017) on structurally similar read across substance Sodium N-methyl-N-oleoyltaurate(137-20-2).Acute oral toxicity study was done in mouse using Sodium N-methyl-N-oleoyltaurate(137-20-2).50% mortality was observed at dose 6630mg/kg bw. Hence LD50 was considered to be 6630mg/kg body weight. When mouse was treated with Sodium N-methyl-N-oleoyltaurate(137-20-2)orally.

Thus, based on the above studies and predictions on sodium 2-[(1-oxododecyl)amino]ethanesulphonate (70609-66-4) and its read across substances, it can be concluded that LD50 value is 4940mg/kg bw. Thus, comparing this value with the criteria of CLP regulation sodium 2-[(1-oxododecyl)amino]ethanesulphonate (70609-66-4)can beNot classifiedfor acute oral toxicity.
