E-liquid, also known as e-juice, contains four ingredients: nicotine, propylene glycol, vegetable glycerin, and flavoring. Electronic cigarettes are a relatively new technology, so few long-term studies have been conducted to determine its long-term effects on users. However, it has been determined that e-juice produces no more carcinogens than FDA-approved nicotine replacement treatments. All of our house blend juices are produced in a sterile, clean-room laboratory, as is the nicotine, vegetable glycerin, propylene glycol, and flavoring we purchase from Nude Nicotine Co. Nude Nicotine has been licensed by the U.S. Department of Homeland Security as a distributor of pure nicotine substrate. In order to ensure maximum quality, Nude Nicotine uses a GC/MS (gas chromatography tandem mass spectrometry), which is a piece of equipment utilized to determine chemical content, to guarantee no unwelcome chemicals are present in every batch of nicotine, VG, and PG they manufacture.
For tobacco cigarette users, nicotine is the most important ingredient in our e-liquid. Nicotine is extremely addictive and can be very dangerous in large quantities. We have varying nicotine levels ranging from 2.4-0% nicotine. The purpose of this is so a person interested in smoking cessation can gradually decrease their nicotine intake, then use 0% to satisfy any hand-to-mouth cravings that smokers often have. In our lab, we use 100% VG based nicotine at 100mg/mL (milligrams per milliliter). We do this to ensure our juices contain accurate nicotine levels. For example, 12 mg/mL is equivalent to 1.2% nicotine per total volume. We do not produce any nicotine levels higher than 2.4% because anything higher is considered potentially hazardous.
Propylene Glycol (PG)
Propylene glycol is a clear, tasteless liquid that is a product of the fermentation and yeast of carbohydrates found in mineral oil. PG levels greatly contribute to the throat hit desired by tobacco users. This organic compound is of a thin consistency, making it more easily absorbable by an electronic cigarette’s heating element. (Vranks, 2013). PG comes in a variety of grades, giving it multiple uses. In our laboratory, we use only food-grade propylene glycol, which is found in m. Many believe PG is unsafe because it is found in antifreeze. Although this is true, only industrial-grade propylene glycol is used in antifreeze. PG was added to antifreeze as a safer alternative to ethylene glycol, which is poisonous to animals (Duprey, 2014). Propylene glycol is commonly used in many products the average American uses on a daily basis, such as cosmetics, food flavorings, pet food, and pharmaceutical purpose. Perhaps the most e-cigarette relative use of propylene glycol is its use in fog producing machines used for fire fighter training. This liquid is quickly metabolized by the body and is generally recognized as safe by The World Health Organization (McKay, 2014).
Vegetable glycerin is extracted from plant oils (usually palm oils or coconut oils) through a process called hydrolysis (Edward, 2014). This liquid is much thicker than propylene glycol, resulting in less of a throat hit and more vapor or “cloud” production. VG is naturally sweet, which adds extra sweetness to e-juice flavors (Vranks, 2013). Many foods contain vegetable glycerin used as a sweetener and various cosmetics companies use vegetable glycerin for its moisturizing qualities (GHC, 2014). Food grade vegetable glycerin is approved for use by the FDA and considered one of the most harmless chemicals to be used on a regular basis (Edward, 2014). At My Vapor Place, we use only food-grade VG in our liquids to ensure the finest quality.
