Polyethylene glycol is that person. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Another immensely important advantage of pentylene glycol is that, in contrast to conventional alcohol, no dehydrating effect occurs even at a higher dosage. It is a preservative: Due to its antibacterial qualities, which help inhibit the proliferation of germs, propylene glycol may help extend the shelf life of cosmetic products and keeps the goods fresh. Summary Polyethylene Glycol vs Propylene Glycol. It secures the water and takes it to the outer layer of your skin. After about a month I did start to feel better.
