This is a guest post written by LadyStrick9, from Chesapeake, VA who often refers to herself as a "vapaholic". What is PG? According to Wikipedia, "Propylene Glycol Alginate, or PGA, is an additive used mainly as a thickening agent in certain types of food. It is made  from the kelp plant or from certain kinds of algae, which is processed  and transformed into a yellowish, grainy chemical powder. The powder is then added to foods that require  thickening. Propylene Glycol Alginate  has been used for many years as a food preservative. Many food manufacturing companies use it in the most common household food items." Juices & carts without PG The February 1, 2012 blog post, "Four Different E-Liquid Lines", by Audrey Schroder, offers a detailed description of products designed for people with a PG sensitivity. "The majority of  the population has no problems with using PG products, as the substance is used in everyday products such as food additives and inhalers. Since this kind of liquid only has VG as opposed to both VG and PG, it is slightly thicker." Vapor4Life offers WOW Vapor VG carts  and juices in Traditional Tobacco (formerly known as Cowboy), Wowboy, Coffee, Vanilla, Chocolate, Cafe Mocha, and 555 and come in all seven strengths (0, 4, 8, 11, 18, 24, and 36mg).   Allergic reactions to PG are varied, according to comments reviewed on a thread on the ECF Forum. No need to be alarmed, however, as very few people are sensitive to PG. According to Wikipedia "The acute oral toxicity of propylene glycol is very low". For example, did you know that PG is used in the following everyday products?
  • Food: Cake mixes, salad dressings, soft drinks, popcorn, food colorings, fat-free ice cream and sour cream. It also protects food from freezing and can be used as a preservative.
  • Toiletries and cosmetics: Lotions, creams, some baby wipes, shampoos, antiperspirants, cosmetics, lipstick, lubricants
  • Other household items: Room deodorizers, cleaners, sanitizers  and yes, new "non-toxic" and "safe" automotive antifreezes
Sarah's story One of the members on the Vapor4Life Forum  (we'll call her 'Sarah'), has a sensitivity to PG. Sarah explains that she did not know she was allergic to PG before she began vaping. In addition to Sarah's sensitivity to PG in vaping juices, she must also be aware of PG in foods and other products. But, the good news is that Sarah doesn't have to stop vaping, she simply uses juices that do not contain PG. Sarah's favorite VG juices from  Vapor4Life are Vanilla and Chocolate. Hopefully now when people talk about PG and VG in relation to  e-cigs, you'll have a better understanding of it. You can usually find LadyStrick9 on the V4L Forum networking with members and guests.
