All about propylene glycol
There’re lots of opinions about propylene glycol that is one of the main ingredient of e-liquids. Some people say that it’s toxic, unsafe and shouldn’t be inhaled. This are all false opinions of course. PPG (propylene glycol) has been used in the food industry since 1930’s (U.S.). PPG has no colour, no smell and sweet taste. There is no danger to inhale it. Toxicity of PPG was tested and results shows no harmful effects. We can find PPG as an ingredient of baking soda, toothpaste, food flavours, nasal spray, frozen yogurt, body wash, ice cream bars and many other products.
