Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A GLP-study in Pimephales promelas and a non-GLP study in Oncorhynchus mykiss, both studies according or equivalent to OECD guideline 203 are available as key studies for propylene glycol methyl ether acetate. These studies are supported by a GLP-study in Oryzias latipes and a non-GLP study in Oncorhynchus mykiss.

Key value for chemical safety assessment

Additional information

In an acute toxicity study with Oncorhynchus mykiss, based on the nominal concentrations of propylene glycol methyl ether acetate ranging from 100 to 1,000 mg/l, the 96 h-LC0 was determined to be 100 mg/l. The 96-hour LC100 was determined to be 180 mg/l. An approximation of the 96-hour LC50 can be made by calculating the geometric mean between 96-hour LC0 and 96-hour LC100. Using this approach an LC50 value of 134 mg/l was calculated. The no observed effect concentration (NOEC) was determined to be greater than 100 mg/l. A 96-hour LC50 of 161 mg/l was established in an acute toxicity study with Pimephales promelas, based on nominal concentrations. Another acute toxicity study with Oncorhynchus mykiss using exposure concentrations from 100 to 1,000 mg/l the 96-hour LC50 was determined to be 130 mg/l, based on nominal concentrations. The Environment Agency of Japan studied the acute toxicity of propylene glycol methyl ether acetate to Oryzias latipes under semi-static conditions during 96 hours. The maximum exposure concentration was 100 mg/l. Based on the nominal concentrations, the 96-hour LC50 was determined to be superior to 100 mg/l. The test report from the Environment Agency of Japan is not available.
