Hey everyone,
One of our renewed commitments is to update our blog weekly. We’ll be spending time regularly talking about the latest information on our products, highlighting some of our most frequently asked questions, discussing the ins and outs of the e-smoking industry, sharing educational tools and experiences and sometimes sneaking a peak inside our company culture here at Johnson Creek. Today I’d like to share with you one of the most frequently asked questions we get.
“What is Propylene Glycol or PG?”
First, the science behind Propylene Glycol (PG): there are generally two most commonly used versions of Propylene Glycol; USP/FCC Grade PG and Propylene Glycol Industrial Grade. In our Johnson Creek Original Smoke Juice line, we use only the highest purity USP/FCC Grade PG. We do not use any Propylene Glycol in our Red Oak Smoke Juice line. In the Red Oak line of Smoke Juice USP/FCC Grade PG is replaced by natural FCC Grade Vegetable Glycerin (VG).
While we don’t use Dow Chemical’s Propylene Glycol products, their website provides easy to understand, in depth, third party information. The below information was taken directly from their website which you can see here.
“The first kind is USP/FCC Grade, 99.8% pure or higher. Propylene Glycol (PG USP/EP) is a pharmaceutical grade of monopropylene glycol (PG or MPG). PG USP/EP is tested for compliance with the current United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP) specifications plus the Food Chemical Codex (FCC). It also complies with the Brazilian Pharmacopoeia (FB) and other pharmaceutical and food regulations in the global markets where it is sold. PG USP/FCC grade is an important ingredient for a multitude of uses, including:
- Ingredient for aromatics in the flavor-concentrate industry
- Wetting agent for natural gums
- Ingredient in the compounding of citrus and other emulsified flavors
- Suspension in elixirs and pharmaceutical preparations
- Very effective humectant, preservative and stabilizer in bakery goods, food flavorings and salad dressings
The second kind is Industrial Grade, <95% pure. Propylene Glycol Industrial Grade (PGI) is an important intermediate in the production of alkyd resins for paints and varnishes. It is the preferred propylene glycol for manufacturing high-performance, unsaturated polyester resins for many uses such as reinforced plastic laminates for marine construction, and gel coats. Propylene Glycol Industrial Grade is also used as a solvent in printing inks, as a preservative in floral arrangements, and as a stabilizer in hydraulic fluids. Other uses for Propylene Glycol Industrial Grade include Unsaturated Polyester, Resins, Urethanes, Coolants and Antifreeze, Aircraft Deicing Fluid, Hydraulic and Brake Fluid, Heat Transfer Fluids, Paint and Coatings.”
What’s important to know is USP/FCC Grade 99.8% pure or higher Propylene Glycol, the type used in our Johnson Creek Original Smoke Juice, is found in many common products we eat or drink every day. USP/FCC Grade Propylene Glycol is often used in the food industry as an anti-freezing agent to prevent products from freezing, such as soft serve ice cream and milkshakes from national fast-food restaurants.
On the other end of the spectrum is Propylene Glycol Industrial Grade. Unfortunately, some media outlets have incorrectly reported that Propylene Glycol Industrial Grade is the kind of PG used in smoke juice. This could not be further from the truth. We’re e-smokers too, and we sure don’t want anything like Propylene Glycol Industrial Grade in our smoke juice. Propylene Glycol Industrial Grade is what would be used in automotive “antifreeze.” We have never and will never use Propylene Glycol Industrial Grade in any product manufactured by Johnson Creek.
We truly believe education is the key to the overall success of the e-smoking industry. One of the aspects of being an industry leader is making sure we continually educate ourselves, our customers and any potential customers about the products we make and the ingredients we use.
