Description of key information

In an acute oral toxicity study the substance was administered to Sprague-Dawley rats (5 animals/sex/dose) by oral gavage at a dose level of 2000 mg/kg bw (single administration). There were no mortalities or signs of clinical toxicity, mean body weight gain was comparable with the control animals and no abnormalities found at macroscopic post-mortem examination. The LD50 is >2000 mg/kg bw and the substance is considered to be practically non-toxic.

In an acute dermal toxicity study the substance was administered to rats (5 animals/sex/dose) by dermal application at a dose level of 2000 mg/kg bw (single administration; semi-occlusive). There were no mortalities or signs of clinical toxicity, mean body weight gain was comparable with the control animals and no abnormalities found at macroscopic post-mortem examination.The LD50 is >2000 mg/kg bw and the substance is considered to be practically non-toxic.

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).

Executive summary:

The acute dermal 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 402 limit test under GLP conditions. The test substance was applied to the skin of five animals per sex in a single dose of 2000 mg/kg bw (semi-occlusive coverage). Total exposure was 24h. Thereafter, the test substance was removed using warm water and cellulose.

Animals were examined for clinical signs 0.5, 1, 2, 3, 4, 5 and 6 hours after treatment. Animals were thereafter daily observed for 14 consecutive days; bodyweights were determined before treatment (day 0), and 7 and 14 days after treatment.

Additional information

Exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance (<5 Pa at 20 degC) and the possibility of exposure to aerosols, particles or droplets of an inhalable size. Therefore an acute inhalation study is not justified.


Justification for classification or non-classification

Based on the findings of a reliable acute oral and dermal toxicity studies, classification of the substance is not justified.
