Best E Liquid Available for Advanced E CigaretteWe have been doing quite a bit of reviews of electronic cigarette on our site, but not much when it comes to reviews of liquid for e cigarette refill.  What good is an e-cigarette without the e juice?  E-juice or e-liquid is probably the most essential part of any vaping experience.

What is E Liquid or E Juice?

So what is an e liquid also known as e-juice or smoke juice?  E Liquid, e juice, or smoke juice, is the fluid that e cigarette utilizes to produce vapor.  It usually contains only a few ingredients such as flavoring (natural and/or artificial), nicotine in various concentrations, and the base liquid.  The base liquid is vital since it keeps the nicotine solution in suspension and transports the fluid to the atomizer to vaporize.  The base liquids for refilling your e-cigarettes are generally propylene glycol (PG) and vegetable glycerin (VG).  Often, you will see the base liquid listed as only PG or VG.  If it doesn’t list the base fluids, then assume it is PG since it is the most common carrier liquid available on the marketplace today.

Often, electric cigarettes such as the KR808D comes with cartridges prefilled with e juice.  These cartridges and the extremely popular cartomizer or clearomizer, CE4V2, can be refilled with a variety of e liquid thus saving you even more money.  A prefilled cartridge is generally sold for about $2 to $3 and holds approximately 1 ml of electronic cigarette nicotine solution.  A typical 10 ml (most common size sold) bottle of smoke juice can often be purchased between $5 and $10 at most retailers.  So, you can see that refilling your e cigarette with your own e juice will save you money and also allows you to try a variety of flavors that will suit you the best.

Base Solution

The base solution is very important component of e juice.  Without the base liquid, which acts as a solvent and carrier, the nicotine solution and flavorings would be too thick to be utilized in any electronic cigarette.  The base liquid thins the nicotine solution and flavorings to it can be transported to the atomizer via wicks and other conduits.  The following are the two most common types of base e-liquid solutions used.

Propylene Glycol (PG)

Propylene glycol based e liquid are the most common e juice sold in America today.  Common uses for propylene glycol is usually in the food or pharmaceutical industries and is FDA approved.  They are used as carrier solutions for oral, injectable, and tropical medicine.  Also used as food additives, E1520, as solvents for artificial and natural flavorings and colorings.  PG is also used as a moisturizer in cosmetics, medicines, food, toothpaste, shampoo, and mouthwash.

One of the reason PG is often used for the nicotine solution for refilling your e cigarette is that it is thinner and has a lower viscosity than VG which allows for easier and quicker recharging of the e cig atomizer.  This prevents dry puffs and reduces the damage incurred to the atomizer when dry puffed.

PG-based e liquid is usually best for flavored nicotine solution due to its natural neutral taste which doesn’t over-whelm the flavoring itself.  When PG is used as the base solution for e-juice, it tends to give the e juice a slight sweet after-taste.

Vegetable Glycerin (VG)

Vegetable glycerin, VG for short, is a natural carbohydrate that is derived from plant oils.  It is often used in the food industry as a sweetener and a key ingredient in many types of cosmetic products.  It is also used in place of alcohol to extract essential oils from botanical items.  VG is much thicker than PG which is one of the reason VG based e liquid produce thicker esmoke.  We are unsure at this writing whether nut-derived oils are used to make VG.

Due to its higher viscosity, VG based smoke juices do not work well in many advanced electronic cigarettes and often burn-out the atomizers for it due to it slow movement to replenish the atomizer tray with e-juice.  Many esmokers burn-out their atomizer due to dry puffing their e-cigs.

PG-VG Blended E Liquid

The major trend in e liquid is the PG-VG blended solutions trying to balance natural ingredients with maximum vapor production and safety with something that will work in most e-cigarettes.  The ratios usually varies from 40-60 to 60-40 (PG-VG).  Of course there are some that are 10-90 or 90-10 also depending on the brand.  Both are water soluble solutions so quality and how it is made really counts.  Some companies try to maximize profits by adding water to increase volume and lower viscosity.

Nicotine in E Liquid

The nicotine in e-liquid is usually artificially derived solution which is thick and gooey.  When added to propylene glycol or vegetable glycerin, the PG or VG acts as a solvent which allows it to be carried into liquid form.  There are a few e-juices on the market where the nicotine is actually processed from tobacco plants.

Safety

Most folks switch to esmokes and electronic cigarettes because they believe that e cigarettes are safer than tobacco cigarettes. Available information and many tobacco researchers at universities do suggest that electric cigarettes are safer, but this has not been confirmed scientifically.  There have been absolutely no long term studies conducted on e-cigarette use and its essential component, e-liquid or e-juice.

  1. Great blog. Thanks for the honest review. It’s true how they market VG as healthy when it really isn’t. I still like the PG-VG blend. Seems to give off more vapor and better throat hit but harsher than pure PG e liquid.

    The increase in exports to China, I find a little surprising, this must surely entirely be raw materials?
    china is the manufacturing capital of the world, I for some reason can’t imagine anything other than raw materials are exported to China.

    Hi I am so excited I found your website, I really found you by error, while I was researching on Aol for something else, Nonetheless I am here now and would just like to say thanks for a remarkable post and a all round thrilling blog (I also love the theme/design), I don’t have time to browse it all at the minute but I have book-marked it and also added in your RSS feeds, so when I have time I will be back to read much more, Please do keep up the great job.

  27. Just about all of the things you claim is supprisingly accurate and that makes me wonder why I had not looked at this with this light before. Your piece truly did turn the light on for me personally as far as this subject matter goes. However there is actually one particular position I am not really too comfortable with so while I try to reconcile that with the actual central idea of your point, let me see what all the rest of the visitors have to point out.Very well done.

  29. Howdy are using WordPress for your blog platform? I’m new to the blog world but I’m trying to get started and set up my own. Do you require any coding expertise to make your own blog? Any help would be greatly appreciated!

  30. Its like you read my mind! You appear to know a lot about this, like you wrote the book in it or something. I think that you could do with a few pics to drive the message home a little bit, but other than that, this is great blog. An excellent read. I will certainly be back.

  31. Hey there would you mind sharing which blog platform you’re using? I’m looking to start my own blog in the near future but I’m having a hard time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your layout seems different then most blogs and I’m looking for something completely unique. P.S Sorry for getting off-topic but I had to ask!
