[EX Q]: Google "propylene glycol" to find out why.  I bought this product, along with several others, without running the ingredients by my wife first (a nurse of 30 years) she was surprised when she noticed it.. we went a googling, and poured my $50 order down the drain afterwards.  There's "pure" and then there's "not so much".....  from the website:  [...]  Propylene Glycol  A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage. Also used in:    Tyre sealant   Rubber cleaner   De-icer   Stain removers   Fabric softener   Degreaser   Paint   Adhesive   Wallpaper stripper  I wrote the company about this concern and they never responded....

[EX Q]: Don't get me wrong, it is good. It is sweet and tart. It is slightly fizzy but not overly so. It is just big enough to quench your thirst before it gets warm.  But WOW, it was sweet. I mean, this is Kool-aid meets Grenadine syrup with some lemon-lime soda tossed in. So if you are looking for something like soda water with a slight flavor, just keep going. If you want a sweet drink to get rid of a craving, then this is for you!

[EX Q]: These chips are flavorful without all the fat of fried. I love love the bbq flavor.  I also like how the chips don't crumble in the bag.
