Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no short-term data available for aquatic invertebrates with Ethyltriglycol methacrylate but there is a long-term toxicity study to daphnia 
(21-day study, semi-static conditions according to OECD 211, Klimisch score 1, Evonik Industries 2012). In this vaild long-term guideline study for aquatic invertebrates (daphnids) Ethyltriglycol methacrylate has a NOEC of 100 mg/L (21-day, daphnia magna) based on mortality of adult daphnids. Therefore the short-term toxicity to daphnids EC50 (48 h) for Ethyltriglycol methacrylate is expected to be greater than 100 mg/L (based on mortality). For this reason there is no reason to perform a short-term toxicity test on aquatic invertebrates.

Additional information

There are no short-term data available for aquatic invertebrates with Ethyltriglycol methacrylate but the mortality data of the adult daphnia in the long-term toxicity study under semi-static conditions according to OECD 211 indicate that up to 100 mg/L there is no immobilisation of daphnia within 48 h, but also within 21 d (Klimisch score 1, Ibacon 2012). In this vaild long-term guideline study for aquatic invertebrates (daphnids) Ethyltriglycol methacrylate has a NOEC of 100 mg/L (21-day, daphnia magna) based on mortality of adult daphnids. Therefore the short-term toxicity to daphnids EC50 (48 h) for Ethyltriglycol methacrylate is expected to be greater than 100 mg/L (based on mortality). For this reason there is no reason to perform a short-term toxicity test on aquatic invertebrates.
