Key value for chemical safety assessment
Additional information
Since no studies investigating the short-term toxicity of 2-ethyl-2-(hydroxymethyl)-1,3-propanediyl dioleate (CAS 25111-05-1) to fish are available, in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5 a read-across to the structurally related source substances Fatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (former CAS 57675-44-2), Fatty acids, C8-10 (even), C14-18 (even) and C16-18 (even)-unsatd., triesters with trimethylolpropane (former CAS 85186-89-6) and Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8) was conducted.
The target substance is characterized by C18 unsaturated fatty acid esterified trimethylolpropane (TMP) (mainly di- and triester). The selected source substances are structurally very similar to the target substance and are thus adequate for the assessment of short-term toxicity to fish. Fatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (former CAS 57675-44-2) is characterized by C18, C18 unsatd fatty acids triesterified with TMP. Fatty acids, C8-10 (even), C14-18 (even) and C16-18 (even)-unsatd., triesters with trimethylolpropane (former CAS 85186-89-6) mainly consists of C18:1 FA triesterified with TMP. The third source substance Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8) is characterized as a triester of TMP and C16-C18 and C18 unsatd. branched and linear fatty acids. This read-across is justified in detail in the overall summary (IUCLID Section 6.1) and within the analogue justification in IUCLID Section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substance was used for the assessment.
Two semi-static studies, investigating the short-term toxicity to fish of the source substance Fatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (former CAS 57675-44-2), are available. Both studies were conducted according to OECD 203. In the first study with Brachydanio rerio no mortality was observed at the tested concentration of 10000 mg/L (Kuttler, 1997). The LC50 (96 h) was determined as > 10000 mg/L (nominal) with highly turbidity at this concentration. In the second study with Salmo trutta the LC50 (96 h) was > 1000 mg/L (nominal) (Källqvist and Tobiesen, 1995). In this study a small amount of an emulsion was observed at the two highest concentrations (320 and 1000 mg/L) and some increase in turbidity was noted. Therefore, the highest tested concentrations in both studies demonstrated a worst case.
One static short-term test (Clemens, 1996) with Leuciscus idus melanotus, a freshwater fish, and one semi-static short-term test (Thomson, 2005) with Scophthalmus maximus, a marine fish, are available for the source substance for Fatty acids, C8-10 (even), C14-18 (even) and C16-18 (even)-unsatd., triesters with trimethylolpropane (former CAS 85186-89-6). In both studies, performed similar to OECD 203 (GLP) no mortality was observed within the tested Water Accommodated Fractions (WAF) loading rates. Clemens determined a LL0 (96 h) ≥ 10000 mg/L and LL50 (96 h) > 10000 mg/L. Thomson observed a NOELR (96 h) ≥ 3200 mg/L and a LL50 (96 h) > 3200 mg/L. Both studies showed no mortality to freshwater and marine fish in the range of water solubility of the source substance.
One static GLP-study, investigating the short-term toxicity to freshwater fish of the source substance Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8), is available. This study (Bogers, 1997) with Cyprinus carpio according to OECD 203 determined a LC50 (96 h) of > 100 mg/L (nominal). No lethal or other visible effects were observed within the tested concentration (100 mg/L nominal) during 96 h of exposure. As test substance drops floating at the surface of the medium, the tested concentration demonstrated a worst case.
Based on the available result from several structurally related source substances (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) which are characterized by a similar ecotoxicological profile and comparable structure, it can be concluded that 2-ethyl-2-(hydroxymethyl)-1,3-propanediyl dioleatewill not exhibit short-term effects to fish up to the limit of water solubility.
