WASHINGTON Lowes, the large home improvement retailer, announced Tuesday that it will no longer sell paint strippers that contain the chemicals methylene chloride and NMP, which have been blamed in dozens of accidental deaths.
The Obama administration, in its final days, concluded that the two chemicals represented unreasonable risks and moved to ban them for use as paint strippers. But the Environmental Protection Agency has not enacted the ban.
For now, Lowes says it will voluntarily remove from its shelves 19 products that contain either of the chemicals, which go by such brand names as Klean Strip, Goof Off and Jasco, many of them made by W.M. Barr in Memphis, Tenn. The products will be removed by the end of the year, the company said. .
EDIT
Lowes is now making its own voluntary move, after being pressed for over a year by environmental and health groups, as well as family members of victims and several online petition drives. This is part of the companys ongoing commitment to bring safer, more affordable options to consumers, a Lowes spokesman said Tuesday.

It's surprising to me.
I've worked quite a bit with methylene chloride in my career, although truth be told, it was a solvent I tried to avoid, since I generally tried to stay away from anything chlorinated. It was a convenient solvent, if I recall, for making certain kinds of cyclic acetals, but I may have been suffering from CO toxicity when I thought that. And it was hard to beat, with the exception of ethyl ether for rapid drying after extractions.
I always thought that its environmental fate involved transformation to phosgene, and I kind of thought that it would be excreted through breathing so quickly as to avoid being metabolized.
It appears I was wrong.
In my career, I did a lot of phosgene work and never tried to generate phosgene from MeCl2, since it was more convenient to work with phosgene from cyclinders.
In any case there is "triphosgene," which some people use to make phosgene.
I do recall that someone once showed me a solution of phosgene in CHCl2, but I always made my solutions in THF. I never liked chlorinated solvents, not chloroform - which can be explosive with bases - not carbon tet, not chlorinated ethanes.
Thanks for the education.
