WHAT IS PROPYLENE GLYCOL?
Propylene Glycol (PG) was not initially used for vaping, as it is commonly used in many household products.
· Diazepam (as the solvent in the injectable form of the product) and other pharmaceutical medicines
· A carrier liquid in fragrances
· Massage oils
· Emulsification agent
· Smoke machines in order to create the smoke seen in the theater and for firefighting training
· Hand sanitizers
· Solvent for food coloring
· Cooling agent for wine and beer
· Coolant in some liquid cooling systems
· In cigar humidors
· De-icing of aircraft
· In deodorant sticks
· A working fluid in hydraulic presses
· An ingredient in UV or backlight tattoo ink
Other products that make use of propylene glycol include cosmetic products, food coloring, cake mixes, sodas, salad dressings, and toiletries. PG is also used as an active ingredient in fog machines used in industry, nightclubs, and theaters.
What Are the Known Side Effects of Propylene Glycol?
Some of the side effects experienced by people that use propylene glycol are muscle pain, sore throat, and stronger smelling urine. These symptoms can all result from using e-cigs that use propylene glycol-based e-liquid. Since PG is considered a humectant (it collects moisture), your throat can become dry after use and potentially sore. It can also result in an increase of lactic acid production by your body causing muscle aches that occur more often than normal. In order to counter-act these symptoms it is recommended that you increase your fluid intake in order to flush the lactic acid from your body more quickly. This will also help with alleviating your sore throat more quickly which normally disappears after a few days of starting vaping. If you find yourself beginning to suffer from loose bowel movements, a rash, or having night sweats you may be allergic to propylene glycol. If this occurs you will need to seek out an electronic cigarette solution that is vegetable glycerin (VG) based instead.
What to Do if You Are Allergic to Propylene Glycol?
If you are allergic to propylene glycol it does not mean that you have to give up on electronic cigarettes. Many e-cig manufacturers produce products that either use VG or have it available as an alternative to propylene glycol. PG also produces an odor-less vapor though it is considered to be thinner and produces less vapor than VG. United States Pharmacopeia and Europe Pharmacopoeia produce, food safe versions of propylene glycol and vegetable glycerin.
What does each one do specifically for electronic cigarette usage?
Propylene glycol (PG) is thinner and has a stronger throat hit (TH). The more PG, the stronger the TH. Some people are sensitive and even allergic to PG, but it's not very common.
Vegetable Glycerin (VG) is what gives you vapor. The more VG, the more vapor produced. VG is thicker and sweeter than PG and makes for a smoother vaping experience. Because of this, it can mute some flavors. Again, some people can be sensitive or allergic, but it isn't very common.
The most common mixture for e-liquid of propylene glycol (PG) and vegetable glycerin (VG) is 50% of propylene glycol (PG) and 50% of vegetable glycerin (VG), depending on the ambient weather temperature.
Vegetable glycerin (VG) is more viscous than propylene glycol (PG). The higher the ambient temperature, the more the vegetable glycerin (VG) should be used.
It is important to know what are the grade and the quality of the e-liquid base when you purchase the e-liquid products. We use the best USP Grade PG and VG ensuring the maximum safety without toxicity risk.
What is the USP EP?
The USP stands for United States Pharmacopeia. The EP stands for European Pharmacopoeia.
The USP is the official pharmaceutical compendium in the United States. It includes chemical descriptions, identifying tests, and purity tests, primarily for active ingredients. USP grade is pharmaceutical grade (the same grade a drug company or pharmacist manufacturing or compounding a formulation for human use would be required to utilize) is the only grade that has any FDA regulation and oversight associated with its manufacture, labeling and marketing.
When you buy USP grade you are assured of 3 things:
The product was made to the exact specifications listed in its USP monograph.
The manufacturer is FDA registered and licensed and the product HAS been approved (including the labeling/marketing material) by the FDA as meeting USP specifications.
The product was made in a FDA certified facility using cGMP (current good manufacturing practices) which are stringent to ensure lot to lot consistency.
Up to now there is no "Vegetable Glycerin" monograph in the USP. We are using FCC (Food Chemicals Codex) and GRAS (generally recognized as safe-for food use) standards.
