There have not been a LOT of tests on the carcinogenicity of Propylene Glycol, but what studies have been done show NO carcinogenic effects - even at VERY high doses, in either humans or lab animals.
With the extensive use of the electronic cigarette worldwide - where Propylene glycol is the main carrier used in the nicotine solution - in 10 to 20 years we should have have proof - one way or the other.
NOTE: E-Cigs have been in use Worldwide for approx. 7 years now - with no problems reported.
Propylene glycol used to be in vehicle antifreeze.
Yes, propylene glycol is a humectant.
The chemical formula of propylene glycol is C3H8O2.
Propylene glycol has covalent bonds.
Propylene glycol can be made through a chemical process called hydration of propylene oxide, where propylene oxide reacts with water to form propylene glycol. This reaction is typically carried out in the presence of a catalyst, such as an acid or a base, to facilitate the conversion of propylene oxide into propylene 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.
The weight of a liter of propylene glycol is approximately 1.036 kilograms.

Propylene glycol is generally considered safer than ethylene glycol for use in coolant/antifreeze due to its lower toxicity. This makes propylene glycol a preferred choice for applications where accidental ingestion may occur, such as in RVs or marine engines. Additionally, propylene glycol is less harmful to the environment compared to ethylene glycol.
No, propanediol and propylene glycol are not the same. Propanediol is a chemical compound with two hydroxyl groups, while propylene glycol is a chemical compound with one hydroxyl group.
Most of them contain propylene glycol.
