All the antifreeze at O'Rielly's, for instance, is ethylene glycol and it is supposed to be compatible with any type of antifreeze or system. Propylene glycol is an ingredient in many lotions, soaps, shampoos, conditioners, shaving creams, deodorants, and more. Similar to ethylene glycol, when inhibited, these glycols also protect HVAC systems against damage from corrosion. Check. Each state has different regulations that require release or spill reporting when a facility meets certain conditions or reportable quantities have been met or exceeded. Interestingly I discovered the FDA allows significantly more PG/PEG in foods and Pharma products than Europe. Big check on that one. Check. 4. Both products are two chemical compounds used as some low temperature heat transfer fluids. Im SO sorry you went through this! I work in community health & just ordered some high quality masks as I work in close contact with my patients & covid cases are high in the community here again ~ they arrived last night ~ & an almost immediate allergic reaction to the product has sent me on a mission to try to understand what happened many calls later & some web searching led me here as one of the product materials is propylene ~ ugh! It is clear that the intermolecular structure of the first member of the PPG family, i.e. Propylene glycol is a colorless, nearly odorless, thick liquid. Its a long story but I am freer of it than ever but still trying to eliminate all of it. Thank you for sharing it with us. And, thank you for sharing so scary ~ I also had a crazy reaction to the covid Pfizer vaccine ~ when I pressed them they said that PEG can cause allergy for a small number of people for me it caused a neurological & systemic reaction that lasted almost 8 weeks your post helps me narrow down that this really was most likely the cause. There are many applications of propylene glycol: use of it as a feedstock for the production of polymers, as a component in some food items, as an anti-icing fluid, manufacture of electronic cigarettes, etc. 1. Polypropylene glycol is produced by ring-opening polymerization of propylene oxide. The safest bet is to avoid it as much as possible, which is why I never use it in my formulations. Its natural that an ingredient used in both brake fluid, flavored iced tea, and deodorant would raise some suspicion. : Not listed 2.7 Standard Industrial Trade Classification: 51229 3. % Propylene Glycol Vol. miniature fluidic and pneumatic polypropylene components for contact with various chemicals. % P200HD Vol% 32.0 0.0 212.0 100.0 0.0 0.0 0.0 0.0 29.1 Polyethylene glycol is a polymer compound derived from petroleum, and the structure can be expressed as H-(O-CH2-CH2)n-OH, while propylene glycol is a viscous, colorless liquid having the chemical formula CH3CH(OH)CH2OH.
