  •  Now acetone you DON'T want to mess with (1+ / 0-)

    IMO, no matter what the MSDS says. Potential carcinogen, helps breach cell membranes by solvating out fat molecules your body very deliberately put in those membranes.

    Windy story: Back in the early 70s when I was a college sophomore, we used to build our own kayaks w/ polyester resin and fiberglass & nylon cloths, working off of molds industrious and better-heeled paddlers had pirated off expensive European racing boats. We slathered our arms with industrial barrier cream and mostly wore gloves and respirators, but I don't even want to know how many mutations and embryonic cancers I spawned in my body from adsorbing the reactive organic resin monomer across my skin and mucous membranes, and all the acetone I adsorbed during cleanup. We practically bathed in the stuff. When we were done after a weekend of boat building we would smell like glue huffers for the next 2 days, exhaling and sweating out all that godawful neurotoxic mess.

    The next year in a biochem lab class, I studied the uptake of radioactive-carbon-tagged glucose by rat brains, feeding the rats the tagged glucose, waiting 24 hours, killing them, scooping out their brain, and preparing to determine the biochemical fate of the radioactive carbon by plopping the brain in 10-20 mL of acetone -- whereupon the entire brain dissolved in about 5 seconds flat into a soluble fat fraction and a ghastly gray flocculant in the bottom of the test tube.

    I took that as a very broad hint that acetone is not good for the brain or other internal organs. Then again, I'm extremely conservative with exposures to organic solvents (except ethanol), pesticides, gasoline, etc., to the point that I drive everyone around me crazy ("stop spraying that shit around my cubicle!!!").

    YES WE DID -- AGAIN. FOUR MORE YEARS.
