Propylene Glycol 57-55-6 Health Issues to Exposure?Author: Pacific Northwest Inspections Group, LLC Date: 22-Aug-2014. Category: Mold Add to Favorites Propylene glycol contributes substantially to the protective power of paints and varnishes, helping preserve surfaces, protect buildings against weathering and maintain the quality and beauty of floors in high-traffic areas. It also facilitates their handling and use in other professional applications:
- as a raw material in the production of alkyd resins for paints and varnishes, propylene glycol controls both the flexibility as well as the hardness of the coatings
- in latex-based architectural paints, propylene glycol is used to provide freeze and thaw stability
- for manufacturing printing inks, certain varnishes, paints or coatings, a special process is required which includes the use of UV-radiation: here di- and tri- Propylene glycol is used in this case because it not only produces low emissions, but also enables increased energy efficiency.
Safe use for over 50 years
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 demonstrate that propylene glycol has a very low degree of toxicity. In the body under conditions of normal low exposure, propylene glycol is quickly metabolised and excreted.
For the environment, studies show that propylene glycol is readily biodegradable and hence does not persist nor does it bio-accumulate - it is readily biodegradable.
Accordingly, there is
- no official hazard classification or labelling of propylene glycol, and
- propylene glycol is not listed "negatively" in any country of the EU
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.
