A complex combination of hydrocarbons produced by the esterification of phthalic anhydride with tridecyl alcohol. It consists predominantly of C13 primary aliphatic alcohols, C11-13 paraffins and saturated and unsaturated C26 ethers and boiling in the range of approximately 120°C to 280°C (248°F to 536°F).
Acute oral toxicity of the study substance was assessed in the female Wistar strain rat.
Following a sighting test at a dose level 2000 mg/kg b.w. in one female rat, a further group of four fasted females was given a single oral dose of study substance, as a solution in corn oil, at a dose level of 2000 mg/kg body weight. Clinical signs and body weight development were monitored in all animals during the study. All animals were subjected to gross necropsy.
There were no deaths. Clinical observations of piloerection and decreased activity was noted transiently (after 2 hours of dosing only) in one animal (female no. 1). There were no signs of systemic toxicity noted in the remaining animals. All animals showed expected gains in body weight and no abnormalities were noted at necropsy.
From these results it can be concluded that the acute oral median lethal dose (LD50) of the study substance in the female Wistar strain rat was estimated to be greater than 2000 mg/kg body weight.
