Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

No experimental data evaluating the acute toxicity of Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates (C10)(CAS No. 97593-30-1) to aquatic invertebrates are available. Therefore, read-across data from a structurally related category member, Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates (C12)(CAS No. 97593-30-1) is used in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. Both substances are esters formed from the combination between acetylated fatty acids and glycerol as alcohol component. These two substances are structurally identical except for the length of their main fatty acid component (being either C10 or C12).The behaviour of these substances in the water phase is expected to be very similar based on their water solubility values (10.2-24.6 mg/L for the C10 and 3.5-21.9 mg/L for the C12 substances, respectively) and log Pow (> 4).

A study evaluating the acute toxicity of Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates (C12)(CAS No. 97593-30-1) to aquatic invertebrates is available (Weyers, 2007). The test was conducted according to OECD Guideline 202, under GLP conditions.Daphnia magnawas exposed to the test substance within a semi-static water regime at 21 ± 1°C. After 48 hours, abnormal swimming behaviour was observed in the treatment group but no immobilization was reported in treatment or control groups and therefore, the EL50 (48 h) was determined to be > 0.108 mg/L (measured).

Based on the results obtained for the structurally similar analogue substance (in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5) no effects up to the maximum achievable concentration in test medium are expected for Glycerides, C8-21 and C8-21-unsaturated, mono- and di-, acetates (C10).
