Additional information

The acute toxicity of isooctadecanoic acid, mono- and diester with glycerol (CAS No. 97358-80-0) to aquatic invertebrates was investigated in a study by Schlechtriem (2012). The test was preceded by a range-finding study in which daphnids were exposed to the test substance at loading rates of 1, 10 and 100 mg/L (nominal, WAF). No immobility was reported at any of the tested concentrations after 48 hours. Therefore, for the definitive study a limit test at 100 mg/L (nominal, loading rate) was performed. This test was conducted according to OECD 202, under GLP conditions. Daphnia magna was exposed to the test substance for 48 hours within a semi-static water regime. After the exposure period, no immobilization or other sub-lethal effects were observed and therefore the EL50 (48 h) was determined to be > 100 mg/L (nominal loading rate).


Based on the above information, no effects of isooctadecanoic acid, mono- and diester with glycerol to aquatic invertebrates are expected up to the limit of its water solubility (0.1 mg/L).
