Lorddrek,
You are confusing propylene glycol with ETHYLENE glycol. Ethylene glycol is used in radiator fluids and in some brands of anti-freeze. Propylene glycol is an FDA recognized safe food additive used to restore moisture to packaged foods, and is also used in liquid medications such as liquid Tylenol, and other "suspension" liquids, etc. It's a common misconception that PG and EG are the same thing, because they both use the word "glycol" in their names, but there are not the same thing.Just wanted to clear that up!
Yes... and to further back up Nicole here... you can buy Propylene Glycol OTC at the local pharmacy. Radiator Fluid is rarely found in the pharmacy
