Although propylene glycol has low toxicity, it exerts high levels of biochemical oxygen demand (BOD) during degradation in surface waters. This process can adversely affect aquatic life by consuming oxygen needed by aquatic organisms for survival.
[58] A high amount of e-liquid contains propylene glycol and/or glycerin. [1] Limited but consistent data indicates that flavoring agents are at levels above the National Institute for Occupational Safety and Health safety limit. [45] High amounts of flavoring agents have been found in e-cigarette vapors. [59]
The propylene glycol molecule. The primary base ingredients of e-liquids are propylene glycol and glycerin. [14] About 20% to 27% of propylene glycol and glycerin-based liquid particles are inhaled. [226] A 2016 study reported that 6% of nicotine, 8% of propylene glycol, and 16% of glycerin was exhaled.
Ethylene glycol and propylene glycol exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters. Large quantities of dissolved oxygen (DO) in the water column are consumed when microbial populations decompose propylene glycol.
When an aqueous solution of propylene glycol in a cooling or heating system develops a reddish or black color, this indicates that iron in the system is corroding significantly. In the absence of inhibitors, propylene glycol can react with oxygen and metal ions, generating various compounds including organic acids (e.g., formic, oxalic, acetic).
The liquid typically consists of a combined total of 95% propylene glycol and glycerin, and the remaining 5% being flavorings, nicotine, and other additives. [31] There are e-liquids sold without propylene glycol, [32] nicotine, [33] or flavors. [34] The flavorings may be natural, artificial, [30] or organic. [35]
Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
