I followed that argument a bit, and what I found was a Seralini study (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5756058/). He is known for some really bad studies about GMOs, those were simply terrible science and he obviously has an axe to grind.
The POEA experiments in that paper were about exposing cell cultures to different roundup compositions and components. It is not surprising that POEA kills the cells in this kind of experiment as it is a kind of detergent. Human cell cultures have no defense against having their cell membranes disrupted by detergents. Real humans are not cell cultures and can't be easily killed that mechanism. We have skin and other barriers like mucous membranes that protect the cells.
I didn't look much further, but seeing that paper as the first result does make me very skeptical about the idea.
