Summary. The applications of polyethylene glycol include use of it as a basis of a number of laxatives, as an excipient, in medicine to treat disimpaction, to fuse axons, as a lubricating coating for different surfaces in aqueous and non-aqueous environments, to create high osmotic pressures, as a polar stationary phase for gas chromatography, as surfactants, as a crowing agent in biology, to concentrate viruses in virology, etc. The Difference Between Propylene Glycol and Food Grade Propylene Glycol. After about 3 months of doing so I became very sick. I still feel nauseous & disoriented and its now the following day. One common ingredient is propylene glycol, primarily found in salad dressing. Due to its moderate acute oral toxicity, ethylene glycol is SARA and CERCLA reportable for spills and transport. Here are a few key reasons. Any help, suggestions would be appreciated.

PPG is used to make an epoxy reactive diluent and flexibilizer, Poly(propylene glycol) diglycidyl ether. Toxicity level is one of the primary differences between propylene glycol and ethylene glycol antifreeze. Compare the Difference Between Similar Terms. It is soluble in many solvents, including water, acetone, chloroform, etc. A salen cobalt catalyst was reported in 2005 to provide isotactic polymerization of the prochiral propylene oxide[2]. : Not listed 2.5 CAS Registry No. Dear Hamza Khalid, they are not the same. Polypropylene is a polyolefinic polymer characterized by a C-C main chain and a CH3 side group. On the ot Chemically it is a polyether with the chemical formula H-[O-CH(CH 3 )-CH 2 Polyethylene glycol is a polymer compound derived from petroleum, and its structure can be expressed as H-(O-CH2-CH2)n-OH. propylene glycol, is definitely determined by the supramolecular self-assembling due to the hydrogen bonds formation by two ending hydroxyl groups of the compound [17,18].Virtually, in liquid propylene glycol (n = 1) there is no contribution of a conventional-type polymer, and only The key difference between polyethylene glycol and propylene glycol is that polyethylene glycol is a polymer material, whereas propylene glycol is a single molecular compound that can be named a diol.
