<p>[QUOTE=&quot;Oldhoopster, post: 8145721, member: 84179&quot;]<i><b>I would also mention that it is simply a fact that PVC that has the damaging softening agent in it off-gasses, puts of gasses. And this is easily proven to everyone who has ever opened and new PVC shower curtain, or a new pack of flips, and noticed the smell.

Because, I didn&#039;t have the scientific data to support it.&nbsp; If you believe the credibility of my observations, and the supporting info from [USER=33176]@Kentucky[/USER] great, I&#039;m glad I could help.&nbsp; If you disagree, no problem.&nbsp; I am only providing annectdotal obsevations,&nbsp; NOT PROOF.</p><p><br /></p><p>If you would have said something to the effect that &quot;I&#039;ve observed xXxX and that may indicate contamination could occur under these conditions&quot;, that would have been fine.&nbsp; But to discount other observations because you know your proof is right, doesn&#039;t fly, especially in a world of complex chemical reactions, with various components that may change, and difficulty finding appropriate chemical data.</p><p><br /></p><p>Who knows, maybe we do need to worry about plasticizer off gassing.&nbsp; Or maybe we don&#039;t.&nbsp; But so far, I see no proof for either and to claim &quot;<i><b>Point being its existence is beyond doubt&quot;&nbsp; </b></i>may be a bit presumptuous[/QUOTE]</p><p><br /></p>
