Description of key information

An acute toxicity study has been conducted with 2-ethylhexyl thioglycolate, a structural  analogue of IOTG, by the oral route (Schmidt et al, 1974). The acute oral toxicity value indicate moderate toxicity, with LD50 value in rats of 303 – 334 mg/kg bw. Acute dermal and inhalation toxicity of IOTG is low,  with 7-hour inhalation LC0 values in rats higher than  0.36 mg/L air (vapours generated at room temperature) or > 14.3 mg/L air (vapours generated at 135°C) (Rampy, 1973) and a dermal LD0 in rats greater than 2000 mg/kg bw (Clouzeau, 1993).
