Statistics:

The most probable LD50 value and its fiducial range are estimated by the method of Thompson, using the Tables of Weil. The figures in parentheses show limits of ± 1.96 standard deviations while the absence of parentheses indicates that no range is calculable because no dosage resulted in fractional mortality

Conclusions:

In the acute oral study conducted in Carworth - Wistar rats, the acute oral LD50 (with± 1.96 standard deviations) for tridecyl alcohol was considered to be 17200mg/kg (12.3 – 23.9).

Executive summary:

Acute Oral toxicity studies were carried out to estimate the toxicity of tridecyl alcohol (112 -70 -9 ) Single oral dose toxicity is estimated by the gastric intubation of groups of five non-fasted, Carworth-Wistar male rats, four to five weeks of age and 90 to120 grams in weight which have been reared in our own colony and maintained from time of weaning on Rockland rat diet, complete.The dosages are arranged in a logarithmic series differing by a factor of two. Whenever possible, the chemical is administered undiluted form.The most probable LD50 value and its fiducial range are estimated by the method of Thompson, using the Tables of Weil. The figures in parentheses show limits of ± 1.96 standard deviations while the absence of parentheses indicates that no range is calculable because no dosage resulted in fractional mortality.50% mortality was observed at dose concentration 17200mg/kg bw. Hence,LD50 (with± 1.96 standard deviations) was considered  to be 17200mg/kg (12.3 – 23.9).When Carworth - Wistar rats were treated with tridecyl alcohol (112 -70 -9) orally.
