and main metabolite)
A limited number of acute toxicity studies are available in fish. These
clearly show that the substance 2-(2-(2-ethoxyyethoxy)ethoxy)ethanol is
practically non-toxic to fish. The LD50 was always in excess of the
maximum tested dose. A figure of 10000mg/L is appropriate. The
substance has also been tested in the zebrafish embryotoxicity test and
showed neither it or its main metabolite 2 -(2 -(2 -ethoxyethoxy)ethoxy)
acetic acid showed any toxicity up to the maximum tested dose of 10mM
