- What is propylene glycol?
- Propylene glycol USP/EP
- Industrial propylene glycol
The use and effects of propylene glycol have been thoroughly researched. It has been used safely for more than 50 years, including adoption in health-sensitive applications such as food, cosmetics and pharmaceuticals, where the molecule mainly serves as non-active ingredient or carrier of other substances.
Studies have proven that propylene glycol has a very low degree of toxicity. In the body, propylene glycol is rapidly converted into lactic acid, in a similar manner to what happens with with sugar (energy) in the muscles during sports.
For the environment, studies have shown that propylene glycol is neither persistent nor does it bio-accumulate - it is readily biodegradable.
Accordingly, there is
In addition, all members of the sector group representing the producers of propylene glycol within Cefic are committed to Responsible Care®, a voluntary initiative of the chemical industry aimed at continuous improvement of their health, safety and environmental performance in handling chemicals.
Propylene glycol is known to be used as a carrier liquid in electronic cigarettes. Upon use of the electronic cigarettes, an artificial smoke is generated among others by fine droplets or mist of propylene glycol. While propylene glycol is a very safe compound, the producers of propylene glycol and members of Cefic’s PO/PG sector group do not support the use of propylene glycol in electronic cigarettes, nor in artificial (theatrical) fogs due to possible effects on the
eye, nose, throat, and respiratory tract membranes as well as the absence of information on potential long term effects from prolonged inhalation of (fine) droplets of propylene glycol.
