What is E Liquid?
E Liquid is the fluid that fuels the Electronic Cigarette. It is what provides the nicotine solution and the flavoring to your Electronic Cigarette. It creates the vapor, which you exhale that mimics the traditional smoke from analogue cigarettes.
E Liquid uses base ingredients to create a smooth flavor. This base can consist of PG (Propylene Glycol), VG (Vegatable Glycerin) or both. Most E-Liquids have mixes containing 70% PG/VG 30% to 50% PG/VG 50%. PG and VG are combined with natural or artificial flavors such as vanilla or apple which creates unique and satisfying recipes.
What is PG (MPG) Mono Propylene Glycol?
Propylene glycol, also called propane-1,2-diol, MPG, Mono Propylene Glycol is an organic compound with the chemical formula C3H8O2. It is a viscous colourless liquid which is nearly odourless but possesses a faintly sweet taste. Chemically it is classed as a diol and is miscible with a broad range of solvents, including water, acetone, and chloroform.
It is produced on a large scale and is primarily used in the production of polymers but also sees use in food processing as the E-number E1520.
The compound is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).
Is PG Safe?
Propylene Glycol has been recoginized by the FDA as Generally Recognized As Safe (GRAS) for human consumption. It has been used for many years by food and drug manufacturers. A common misconception is that it is possible to manufacture E-liquid that is PG Free (100% VG) however all flavors contain PG and it is one of the most common solvents used in flavor manufacture. The chances are that most people consume PG everyday in one form or another. Approximately 1 in 10 people can have some kind of reaction to using PG although the reactions are generally very minor and are often in the form of some kind of upper respiratory tract irritation which will usually return to normal after a few weeks of not using it. If the user suffers any kind of reaction they should contact their Doctor and ask for advice.
Why does E Liquid Contain PG?
E Liquid manufacturers usually add PG to their liquids to give what is know as a 'throat hit' when the user inhales. This mimicks the throat hit felt when smoking traditional cigarettes. Without PG the E Liquid can be very smooth and often sweet which detracts from the experience that a traditional smoker expects. The PG also helps to reduce the viscosity (thickness) of the E Liquid. This increases the wicking rate to reduce the user burning the coil in their tank by creating a dry burn. Wicked Wizard does not add any additional PG to our Cloud Base range to give a great tasting, smooth vapor experience.
What is VG (Glycerol, Vegetable Glycerin)?
VG also known as Glycerol, glycerine or glycerin is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides. Glycerol is sweet-tasting and is non-toxic.
In food and beverages, glycerol serves as a humectant, solvent, and sweetener, and may help preserve foods. It is also used as filler in commercially prepared low-fat foods (e.g., cookies), and as a thickening agent in liqueurs. As a sugar substitute, it has approximately 27 kilocalories per teaspoon (sugar has 20) and is 60% as sweet as sucrose. It does not feed the bacteria that form plaques and cause dental cavities. As a food additive, glycerol is labeled as E number E422.
Glycerol is used in medical and pharmaceutical and personal care preparations, mainly as a means of improving smoothness, providing lubrication and as a humectant. It is found in allergen immunotherapies, cough syrups, elixirs and expectorants, toothpaste, mouthwashes, skin care products, shaving cream, hair care products, soaps and water-based personal lubricants. In solid dosage forms like tablets, glycerol is used as a tablet holding agent. For human consumption, glycerol is classified by the U.S. FDA among the sugar alcohols as a caloric macronutrient.
Why does E Liquid Contain VG?
E Liquid manufacturers add VG to their liquids because when it is heated and inhaled it produces the vapor which the users look for. The higher the VG content the bigger vapor (clouds) are produced. By increasing the percentage of VG and reducing the percentage of PG gives a smoother vaping experience giving the user the chance to take bigger inhalations and blow bigger clouds. At Wicked Wizard we only add VG to our Cloud Base Eliquids to produce massive clouds ideal for RDAs, RBAs and Sub-Ohm tanks for cloud chasing, competitions and Vape Tricks. If you tried to use a high VG E-liquid in a standard clearomizer such as a CE4, CE5 or EVOD it would generally clog the clearomizer or produce a dry burn.
