Executive summary:

The acute oral toxicity of the test substance CAS 91744-23 -9, Glyceryl Citrate/Lactate/Linoleate/Oleate) to male and female Sprague-Dawley rats was investigated in a OECD 401 limit test under GLP conditions. The test substance was given to five animals per sex in a single dose of 2000 mg/kg bw.

Animals were examined for clinical signs up to 6 hours after the treatment. Thereafter, animals were daily observed for 14 consecutive days; bodyweights were determined before treatment (day 0), and 7 and 14 days after treatment. At the end of the 14 day observation period all animals were subject to necropsy.

During the study none of the animals died and animals did also not show clinical signs. Body weight gain was normal for all animals. Gross pathology did not result in any findings. Therefore, it can be concluded that the substance is practically non-toxic (LD50 > 2000 mg/kg bw).
