> Jim I'm no chemist, and I really don't understand all the technical formulations. I had a list at one time but lost a lot of stuff when Windows decided to eat the partition tables on the hard disk. One word that comes to mind is phalates or something like that. I just did a search and can't seem to find the magic incantation that lets google show the list again. But I do recall a comment to the effect that the proportion of different resins used in the manufacturing process is never quite exact, so there is always an excess of one or another. You can feel this on the surface of the hdpe jug occasionally. It sometimes has a slippery feeling. So the manufacturing process is not really well controlled, and the distilled water we buy can literally change from one jug to the next. Ode has said the same thing. PET bottles that are manufactured to hold distilled water doesn't seem to have these problems. But that may not hold true for other PET containers, for example, those intended to hold spring water. I tried storing cs in all kinds of different containers and bottles. Some PET bottles that once held spring water turned the cs deep yellow, but it was a different tint that you see with cs. Also, there was no Tyndall, so it wasn't AgOH agglomeration.
