I know but I thought this recent article about DEG again might be of some interest - I think it's really frightening and very sad.
Some time ago several people posted about tainted and/or adulterated cough syrups and toothpaste from China that contained DEG (diethylene glycol) instead of glycerin. This Times piece is long but it traces the DEG history back more than 10yrs and presents a very good discussion about the incredible difficulties encountered when trying to track down "ingredients" from foreign suppliers particularly when people, companies and countries flat out lie.
