Want this question answered?
Propylene glycol has covalent bonds.
Propylene glycol was proposed as an air germicide; it is also an ingredient in antibacterial solutions.
Ethylene glycol
From www.fao.org/ag/agn/jecfa-additives/specs/Monograph1/Additive-360.pdf Propylene glycol alginate is an ester of alginic acid in which some of the carboxyl groups are esterified with propylene glycol, some neutralized with an appropriate alkali and some remain free.
Would you brush your teeth with anti-freeze from your car's radiator? Absolutely NO, WHY include this ingredient in toothpaste if it is considered harmful?? You are confusing PROPYLENE Glycol with ETHYLENE Glycol. Propylene glycol is not toxic. Ethylene glycol is the substance in engine coolant which will damage internal organs, especially the kidneys. Check out the MSDS for both substances for further information.
Propylene glycol used to be in vehicle antifreeze.
Propylene glycol has covalent bonds.
The chemical formula of propylene glycol is C3H8O2.
Propylene glycol in fireball
Propylene glycol was proposed as an air germicide; it is also an ingredient in antibacterial solutions.
Most of them contain propylene glycol.
Propylene glycol.
Ethylene glycol
Yes, Ethylene glycol and Propylene glycol are very similar chemically, therefore, can be mixed without any bad consequences for the engine.
You could determine its boiling point. The boiling point of ethylene glycol is 197.3 oC, and the boiling point of propylene glycol is 188.2 oC.
Sodium chloride is soluble in propylene glycol. The solubility is 71 g/L at 25 0C.
all i know is that the main ingredient is ethylene glycol
