Propylene Glycol (PG)


Propylene glycol, also called 1,2-propanediol or propane-1,2-diol, is an organic compound. It is a colorless, nearly odorless, clear, viscous liquid with a faintly sweet taste, hygroscopic and miscible with water, acetone, and chloroform.


Propylene Glycol is used:

In food – Cake mixes, salad dressings, soft drinks, popcorn, food colorings, fat-free ice cream and sour cream. It also protects food from freezing and helps as a preservative.

In toiletries and cosmetics – Lotions, creams, some baby wipes (though not in the brand I have in my cabinet), shampoos, antiperspirants, cosmetics, lipstick, lubricants

In other household items – Room deodorizers, cleaners, sanitizers and yes, new "non-toxic" and "safe" automotive antifreezes

And specific to the soap making and toiletry making industry, it is also used as a carrier in fragrance oils and in many melt and pour soap bases.
