Does propylene glycol decompose?
In addition to the decomposition of glycerol, the second major ENDS component, propylene glycol, has been shown to degrade upon exposure to high temperatures and oxygen.
Is propylene glycol safe to vape?
Vaping propylene glycol and vegetable glycerine may lead to lung inflammation. Researchers have found that using e-cigarettes with the e-liquid refills containing propylene glycol (PG) and vegetable glycerine (VG) may lead to inflammation of the lungs over a period of time.
What is glycol in food?
Propylene glycol is often used to maintain the moisture in prepared foods and works to maintain their flavor quality for longer periods of time. It is also found in flavorings, such as vanilla or almond extracts used in baking, and in some types of food coloring.

Are hydrates unstable?
In general, hydrates are not stable enough to be isolated as the equilibrium shifts back to starting materials (due to Le Chatelier’s principle). However, hydrates are the reactive species in the aqueous oxidation of aldehydes to acids.
Why is 2 O unstable?
The instability of gem-diols is due the fact that hydogen bonding between the 2 OH- groups increases the repulsion causing a strain on the C-O-H bonds. In case of compounds of boron, a greater bond angle (due to sp2 hybridization of boron) prevents intramolecular hydrogen bonding.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
