<p>[QUOTE=&quot;calcol, post: 2982916, member: 77639&quot;]There is an old Latin phrase known to old toxicologists:&nbsp; sola dosis facit venenum (only the dose makes the poison).&nbsp; We know that&#039;s not always true.&nbsp; There are no safe levels of some carcinogens and some engineered nucleic acids and proteins; one molecule might kill you.&nbsp; But it&#039;s pretty much true, and it is true of acetone toxicity.&nbsp; After all, your body makes it continually from fat, usually in tiny amounts, and it&#039;s excreted in your breath, feces and urine.&nbsp; You&#039;ll make more of it if you haven&#039;t eaten for a while or in some disease states.</p><p><br /></p><p>Nail polish remover isn&#039;t pure acetone, but you can certainly smell acetone in it.&nbsp; It&#039;s intended for short exposure, and the main area to which it&#039;s applied, the nails, absorb very little of it.&nbsp; Painters have a higher incidence of lung cancer and other pulmonary problems than the general population.&nbsp; Lots of epidemiological studies.&nbsp; For example: Lung Cancer Risk in Painters: A Meta-Analysis by Guha et al. in Environmental Health Perspectives 2010 Mar; 118(3): 303–312.&nbsp; How many of their lung problems are attributable to acetone is hard to say.&nbsp; I&#039;d guess sanding dust, paint thinner and toluene are worse offenders.</p><p><br /></p><p>The safe thing to do is minimize your exposure to acetone to avoid toxicity, but it&#039;s not much of a risk if used properly.&nbsp; Beyond that, remember it and its vapor are very flammable.&nbsp; Even it were totally nontoxic, that would be scant comfort if your house burns down with you in it.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
