Research: Propylene glycol vapor eliminates air-borne microorganisms, consisting of streptococci

Study: Propylene glycol vapor kills airborne bacteria, including streptococci


While the cigarette smoking of flammable cigarette is verified to reduce the resistance system and also making cigarette smokers extra prone to colds and also the influenza, decades-old study suggests that vapers might have a secret benefit.  In several research studies performed as much back as the 1940s, Dr. Theodore Puck achieved success in showing that the vapor created from propylene glycol eliminates numerous types of air-borne microorganisms. Possibly most notable are streptococci, pneumococci, staphylococci, the flu infection, and also various other microorganisms.   

Propylene glycol is a significant part of e-liquids made use of in both open-tank vaping tools and also non reusable e-cigarettes.  It’s likewise a sweetening agent typically made use of in baked items, cake icings, and also gelato, which implies that it is authorized by the U.S. Fda and also thought about risk-free for human usage.

The Black Plague, propylene glycol, and also breathing illness

In his 1943 research qualified The Antiseptic activity of propylene glycol vapor on microbes put on hold in air (NLB-NIH), Dr. Puck found that when propylene glycol is warmed to a plain 80 level Fahrenheit, it’s vapor can substantially assist people dealing with a selection of breathing illness.  Despite the fact that mass-marketed vaping had actually not yet been created, Puck unintentionally came across his searchings for when investigating The Black Plague of the 14th century in England. 

Constantly intellectually interested given that he was a young kid, Puck was constantly fascinated concerning exactly how and also why the Black Plague finished.  While the illness would certainly stick around in Europe for centuries, the city of London was rather effective in eliminating it relatively overnight after the afflict had actually eliminated around 70,000 Brits in between 1665-66.   Exactly how did they do it, Puck constantly questioned?

After reviewing heaps of historical files, Puck quickly discovered that the residents of London were so overloaded by fatality and also enduring that they at some point chose to essentially shed the community to the ground.  The concept at the time was that the fire would certainly ruin whatever virus or microorganisms that was triggering the harmful break out. 

Oddly, their arson-inspired reasoning appeared to function.  Virtually quickly after the fire, situations of the Black Plague started to go down dramatically.

The Black Plague was triggered by yersinia pestis, a germs typically located on rats and also commonly sent to 14th century Londoners by flea attacks.  Dr. Puck supposed that something in the pale air should have added to the break out’s death by eliminating this Yersinia pestis microorganism. 

He started checking all kind of materials prior to coming across propylene glycol. Not just did Puck establish that this e-liquid component eliminates yersinia pestis, however he likewise located that it eliminates numerous sort of microorganisms understood to trigger all sort of health problem in human beings.  Streptococci alone can trigger impetigo, scarlet high temperature, and also obviously, the well-known strep throat (pharyngitis). 

“The murder of air-suspended microorganisms using extremely tiny focus of vapors of different substances, especially propylene glycol and also triethylene glycol, was reported. Under the speculative problems utilized, many sort of microorganisms, consisting of pneumococci, hemolytic streptococci, staphylococci, flus, etc., along with flu infection, when splashed right into ambiences including such vapors, were eliminated so swiftly that no microbes or infection can be recouped from the examination chamber. Propylene and also triethylene glycols were picked for personal research, given that these substances are fairly safe and also in vapor kind are odor-free, unsavory, and also non-irritating to the breathing mucosa. The level of germicidal task of the vapors was observed to rely on the focus of the glycol in the ambience. Moreover, the efficiency of any kind of provided focus of glycol vapor can be altered considerably by changing particular speculative problems, such as the quantity of society inoculum atomized right into the air, the variety of microorganisms each of quantity, the loved one moisture and also temperature level of the ambience, and also the state of microbial suspension.”

Dr. Theodore Puck’s study was thought about so advanced that the New York City Times reported on his fatality in 2005.   His study was likewise made use of as the foundation for even more current research studies in the area of vaping study.  As an example, the California Division of Public Health and wellness revealed in 2017 that the poisonings direct exposure of used e cigarette vapor is minimal, specifically when contrasted to the cigarette smoking of flammable cigarette cigarettes.
