Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Acute tests evaluating the toxicity of diethyleneglycol diformate (CAS 120570-77-6) to aquatic organisms from three different trophic levels are available. Since the substance is susceptible to abiotic hydrolysis (DT50: 1.24 d (pH7) and 2.98 h (pH8) (HYDROWIN v2.00)) it is likely that the possible effects of the parent substance as well as the hydrolysis productswere assessed in the available studies. Aquatic invertebrates turned out to be the most sensitive taxonomic group with a LC50 (48 h) of 33.1 mg/L, whereas no toxicity was observed in marine fish up to a concentration of 33.1 mg/L after 96 h (nominal). An EC50 (72 h) of 207.8 mg/L was reported for marine algae. Long-term toxicity testing was not deemed necessary.The environmental exposure assessment for diethyleneglycol diformate according to Annex XI, Section 3 indicates no risk for the aquatic compartment (all RCR < 1; please refer to Chapter 9 and 10 of the Chemical Safety Report for detailed information). Thus, long-term testing with aquatic invertebrates and fish is not deemed necessary.
Diethyleneglycol diformate caused inhibition of the respiration rate of activated sludge microorganisms resulting in an EC10 (3 h) of 580 mg/L. Nevertheless, the overall potential to cause inhibition of activated sludge microorganisms is low and significant inhibition of the subsequent degradation process in sewage treatment plants is not expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
