Guest guest Posted September 1, 2007 Report Share Posted September 1, 2007 Hi Melissa: Congrats on being a current chemistry student. Sorry, I did not take time to explain my " is/was " used as antifreeze. A few years ago, our daughter did a bit of research and a news article on the propylene glycol, and I was using that info from talking with her about it. It was my understanding that it was the old ingredient in antifreeze. If not, then I certainly apologize for the misinformation, and will go running to the corner with my tail tucked, cheeks & ears burning. Second: propylene glycol is used as an antifreeze. It is used in many products nowadays to keep them from freezing. Everything from scented dirt for hunting, baits, numerous things that we never even think of. It's my opinion that it definitely does cause birth defects, even in animals. Imho not everything that is legal or approved as safe by the proper officials is good for you! For instance in your very locale, drive thru Oak Ridge on Hwy's 58 & 95? and look at the dead trees (it was worse before the several year reforestation project, and think about those safe chemicals those folks worked with and what it may have done to the earth and such. Talk to some of the cancer victims from working there with those same supposed safe chemicals and wonder how safe it really is/was... Every week I hear of folks eat up with cancer due to just working in the area. Studies of life spans of late 50's if you live and maybe work there. I'm truly sorry I don't have the correct terminology for chemistry formulas. We can't all be scientists and chemists. Lord knows East TN has more than our share of them. <Grin> No reason to attack about it. There are better ways to get your point across. Nuff said.

Propylene glycol is commonly used in food manufacture. Any product such as frozen food that has a sauce or gravy often has propylene glycol in it to act as a humectant. It is also used in animal feed. It has a high freezing point and can be used as a de-icer, not an anti-freeze, however, so can alcohol. Just because it has been used that way, does not mean it is poisonous.Y ou can have the opinion that it causes birth defects, but that opinion has nothing in the way of scientific evidence to back it up. Propylene glycol is bio-degradeable and breaks down in the environment within 48 hours. J Quote Link to comment Share on other sites More sharing options...

We all know that to err is human and to forgive is divine.

Guest guest Posted September 1, 2007 Report Share Posted September 1, 2007 According to the Agency for Toxic Substances and Disease Registry, propylene glycol is used in antifreeze, although it is also considered as safe to be used in food products. See http://www.atsdr.cdc.gov/tfacts96.html.

Guest guest Posted September 1, 2007 Report Share Posted September 1, 2007 Deb, Sorry if I hurt your feelings. I've spent a couple of hours skimming through some of the hundreds of toxicity studies on propylene glycol I found in the Science databases I have access to through the university. The only ones that showed serious toxicity concerns were for long-term sedation of ICU patients who may become sensitive to propylene glycol, which is used as a solvent for lorazepam. Propylene glycol has been very extensively studied...by the US government, by various US universities, by various EU universities and governments...and every study concludes that it is GRAS. It can cause problems at high doses, but then again, so can sodium chloride (table salt) and dihydrogen oxide (good 'ol H2O). Almost anything can cause problems if you get too much of it. And while propylene glycol is used as a deicing agent ( i.e. " antifreeze " )...so is sodium chloride (salt). " Scary industrial uses " does not make a chemical dangerous. Have a good weekend, Melissa Quote Link to comment Share on other sites More sharing options...
