Executive summary:

In order to evaluate the acute oral toxicity of ‘glycerides, C16 and C18-unsatd. and C18-unsatd. hydroxy’ (as castor oil) in rats, an acute oral toxicity study was conducted. The procedure performed in this study was based on the OECD Guideline 401, 1987 and to GefStoffV, Aug. 26th, 1986, (BGBI 1470).

A group of 5 fasted male and female Wistar rats were exposed to a single oral dose of 5 mL/kg bw. Clinical signs and mortality were recorded during the 14 day observation period. Necropsy was conducted on moribund animals and those terminated at test end.

No clinical signs and no mortality were observed. There were no treatment-related effects on body weight and nothing abnormal was found in the animals necropsied on Day 14.

The acute oral median lethal dose (LD50) of the test substance was therefore considered to be > 5 mL/kg = 4,952 mg/kg bw.
