  • A Classic Vaping Battle: PG vs. VG

    A Classic Vaping Battle PG vs. VG

    Propylene glycol. Vegetable glycerin. As a vaper, you’ve probably heard these words tossed around a million times. But do you really understand what they are and what they mean for you? We’re here to shed some light on the specifics of propylene glycol, vegetable glycerin, the differences between them, and how they work in e-liquids around the globe.

    Propylene glycol - or its more technical name, propane-1,2-diol - is a liquid alcohol that’s used as a solvent for too many products to count. Propylene glycol, or PG for short, is created through a process of fermentation of yeast and other carbohydrates. You may have heard frightening statements such as, “propylene glycol is used in antifreeze, and therefore isn’t safe for consumption”, but that’s not true whatsoever. While propylene glycol is used as a solvent in antifreeze, it’s also used as a storage agent for foods, plastics, and other industries that deal with consumption or health. In vaping, PG is used as a solvent to store e-liquids while retaining flavor for long periods of time.

    Vegetable glycerin, also known as VG, is a more natural liquid solvent. Produced from extracts of plant oils such as palm, soy, or coconut, vegetable glycerin is used heavily in the food industry as a solvent to deliver sweetness and moisture to various products. Other products like lotions and shampoos use the naturally occurring compound as a humectant - something that attracts moisture to whatever it is applied to. In vaping, vegetable glycerin is also used to store e-liquids. However, it’s usually used in flavors that require more sweetness or flavors that should produce more vapor.

    So what’s the difference between VG and PG, and why do you hear so many arguments about the two chemicals? Well, it comes down to a few key factors. The major factors that vapers argue about in relation to the ingredients used are all related to each other in multiple ways. Propylene glycol is used extensively in flavors that are substitutes for nicotine, as it provides a more “realistic” throat hit, according to traditional smokers who have transitioned to vaping. Propylene glycol also carries synthetic flavorings in a more true manner than vegetable glycerin, not changing the tastes over time as vegetable glycerin might. Vegetable glycerin tends to give a smoother and less realistic throat hit. As previously mentioned, it is significantly sweeter, meaning that flavors suspended in VG are more likely to be on the sweeter side. However, it produces significantly thicker and robust vapor, so it’s perfect for the cloud chasers out there.

    Now, propylene glycol and vegetable glycerin were previously used as single suspension liquids for e-juices. In more recent years, however, VG and PG have been used in conjunction in various e-liquids. Ratios of VG to PG are something you will probably hear vapers talking about pretty regularly, as e-liquids will offer huge ranges of ratios to satisfy the urges of many vapers. Bringing it back to the differences in VG and PG will help clear up why some vapers want certain ratios of the two in their e-liquids. Having VG and PG in e-liquids will compliment and bring out certain tastes in the flavors. Simultaneously, the hit will be both smooth and robust, and each pull will produce more vapor that is easily obtained than from a liquid that only contains one of the two compounds. Usually, an 80-20 ratio of one to the other will be used. This ratio signifies that either the vaper is looking for a strong throat hit with original flavors and a tiny bit of added sweetness (i.e. an 80-20 PG to VG ratio), or a huge cloud with a much sweeter flavor and a smoother throat hit (an 80-20 VG to PG ratio). Some vapers will even look for a 50-50 ratio, to get the best of both worlds.

    Now that you know what VG and PG are, you can be a more educated vaper. Vapers will always discuss their preferences for vegetable glycerin or propylene glycol in their e-liquids. While you should take their advice, experiment for yourself. Neither chemical is harmful to you, and only you can figure out what ratio is perfect for your vaping sensibilities.

  • Temp Control Means Almost Everything

    Temp Control Means Almost Everything

    Temperature control vaping is still a fairly new addition to the world of vaping that's extremely rewarding in ways you couldn’t have imagined. For instance, have you ever pulled a completely dry hit that left a terrible, burnt taste in your mouth for the rest of the day and basically ruined your vaping experience that day? Or maybe you just get a slight hint of burning from your e-liquid that no matter what, you can never get rid of? Well, temperature control on MODs was designed to counteract exactly those scenarios.

    A MOD's temperature control usually works by presenting the option to set a Fahrenheit (or Celsius, if you’re a metric system user) value that no matter what the device will not surpass. The control system will closely monitor coil temperature, and the second the coil hits the set temperature will take over control. The system will then adjust power to keep the coil at a constant temperature no matter your pull size. Some brand new systems may also include a joules system. Joules are a slightly more accurate way to read power. Unless you're familiar with this measurement, then it's probably wiser to use wattage.

    Not only is temp control implemented to create a more enjoyable experience, it was also created to shepherd in a new era in vaping safety. By creating a completely safe way of limiting temperature with no human input, the system makes sure that it doesn't overheat. System overheating could lead to many parts of the MOD becoming damaged, from the battery melting to tanks cracking and breaking. It could also lead to burnt out wicks or unpleasant dry hits. The temperature control system makes sure, none of these things occur.

    Though most vapers think dry hits are just unpleasant, they can actually be harmful. Certain types of wicking material can actually burn and produce harmful chemicals. Furthermore, the range at which temperature control systems work offer ultimate tweak-ability. Since e-liquid taste can change between pulls due to the coil being not heated during the first hit and pre-heated for the second, to get that same taste, a temp control system will make sure the coil gets heated and stays heated. On top of that, the huge range lets vapers experiment with e-liquids at almost any temperature they could dream of.

    Temperature control systems in MODs are currently looked at as a luxury. But when you break down exactly what these systems do, it almost seems like they should be a necessity. By offering both safety and more usability than ever, temperature control systems on MODs are some of the most appealing features on the market today.

  • Get Your Head in The Clouds

    Get Your Head in The Clouds

    I'm no psychic, but if you're reading this, chances are you're trying to figure out how to get massive clouds without damaging your MOD. If I'm right, which I am, then you're in luck! What I'm about to explain will blow your mind, not your MOD, and help you to make the biggest clouds you've ever seen.

    In an attempt to create those sought-after clouds, many vapers turn to a method known as “sub-ohm vaping.” Sub-ohm vaping is a process that pushes the limits of your battery. When you do this, it can cause the power load to exceed its limitations. This may cause the device to melt, overheat, or even explode. Sub-ohm vaping is dangerous and should never be attempted, but fear not; I'm going to give you three methods to creating those giant clouds we all know and love, without the risk of explosion.

    The first method is purchasing an e-liquid using high percentages of vegetable glycerin (VG). VG captures moisture from the air, creating those monumental vapor plumes. The more VG your e-juice has, the larger the clouds you'll produce. The issue with this method is the more VG you use, the more diluted your flavor will become.

    The next method is to use low ohm coils. Using a device with lower ohm coils is a quick and easy way to increase your vapor production. Lower ohm coils have less resistance, which causes them to become hotter in less time. This process will allow the e-liquid to burn faster, producing more vapor output. However, you'll run through your e-liquid much faster than usual.

    The final method involves reducing your nicotine strength. Many cloud chasers prefer not to use nicotine for this very purpose. Lowering the nicotine level to about 0.6% can help achieve larger clouds through a process referred to as “direct pulling.” Direct pulling is the process of inhaling directly from the mouthpiece of the device, allowing higher amounts of vapor to be inhaled. This method is highly effective in achieving larger clouds.

    Whether you choose to purchase an e-juice with a high VG percentage, purchase lower ohm coils, reduce your nicotine levels, or even chose to do all three at once, just take into consideration the pros and cons to each method and choose what's right for you. Before you know it, you'll be making clouds so large, you'll have your own atmosphere!

  • VG vs PG - E-Juice PG/VG Ratios: Do They Really Matter?

    VGvsPG Ratios Explained Infograph

    Beginning vapers are likely to focus primarily on two things: their hardware and the flavors and nicotine levels of their e-liquids. After they gain some experience with vaporizers, their attention usually turns to the effects of variable voltage and wattage, and they may move on to mods.

    Read on and and learn everything you need to know about VG vs PG ratios.

    If you not into reading - just scroll down and check out the infographic we made.

    The one consideration those relatively new to vaping (and some experienced vapers) often ignore is the “base” of their eliquid – propylene glycol (PG), vegetable glycerin (VG), or a mixture of the two. That’s a mistake, because choosing the right PG/VG combination is just as important to throat hit and vapor as is finding the ultimate voltage setting. Here’s a quick guide to the possibilities – and why they definitely matter.

    Characteristics of PG and VG

    The base of an e-juice has two functions. It “carries” the other ingredients of the liquid, and it plays a major role in flavor, throat hit and vapor produced. However, the boring details about PG and VG aren’t necessary for most vapers to study. Both bases are considered safe and are widely used in a variety of consumable products. The one major “health” issue to consider is that a small number of people are allergic to propylene glycol, experiencing symptoms like hives, rashes or upset stomachs. PG can also cause throat irritation for some, for reasons which will become obvious in a moment. Switching to an eliquid with a VG base may be necessary for these vapers.

    Each of the bases has distinctly different characteristics which affect the vaping experience.

    • Propylene Glycol: PG is a thin, non-toxic synthetic liquid which has no natural flavor so it’s better at carrying the flavors added to e-juice, and has a longer shelf life because of its non-natural ingredients. It carries a stronger throat hit (a major reason why vapers occasionally experience throat irritation). However, its higher temperature resistance means higher voltages are required to create vapor, so there’s often less vapor on the inhale, thinner clouds on the exhale, and the possibility of a burnt taste if the vaporizer’s voltage isn’t regulated properly.
    • Vegetable Glycerin: VG is a thicker, natural substance with a naturally sweet flavor, which has a shorter shelf life due to its organic nature. When used as a base for e-liquid it creates a lot more vapor with less of a throat hit than PG; that means a smoother inhale and the huge clouds many vapers love to exhale while doing tricks or cloud chasing.

    VG.PG Ratios

    There’s one other important difference between the two. Since PG is thinner, it’s absorbed quickly by the wicks and less likely to gum up the coils on atomizers. The more viscous VG can quickly build up on coils, wicks and other components so more frequent cleaning is required; and VG-based liquid won’t work well at all with some older clearomizers with small coils. Many vapers prefer to use VG liquid with rebuildable atomizers for that reason. On the other hand, sub-ohm tanks are built to withstand higher voltages and can easily handle VG-based juice.

    Why Mix PG and VG?

    Initially, many large e-juice manufacturers created their products with PG bases, and some offered VG e-liquids as an option for those allergic to propylene glycol. However, they quickly discovered that creating a base by mixing PG and VG allowed them to combine the best elements of each substance, to provide a range of choice for vapers looking for different characteristics in their e-juice.

    If you mix your own e-liquid, of course, you have the ultimate control. You will likely discover that certain PG/VG ratios work best with your vaporizer and that different ratios are preferable for different families of flavors; you’ll also find that high-VG juice mixed with several flavors can take longer to steep, and that most high nicotine concentrates and “interesting” flavors aren’t available in a VG suspension.

    The best approach when trying different PG/VG ratios is to start with either 70/30 or 50/50 as a baseline, and then go from there.

    Common PG/VG Ratios and Their Uses

    Still not quite sure which PG/VG ratio might suit you best? Let’s take a more detailed look at the possibilities:

    • 100% VG (Max VG): There are two primary reasons to choose 100% VG – an allergy to PG or competitive cloud chasing. There’s almost no throat hit, and the sweet VG definitely alters other flavors in addition to creating an equipment maintenance issue.
    • 80% VG/20% PG: (80/20) There’s very little throat hit but lots of thick vapor with this ratio; the sweetness of the VG really starts to affect the flavor at this level. This is also where the high VG content can really start to wreak havoc with gunk on the coils and wicks.
    • 70% VG/30% PG: (70/30) This is the best level for those who are interested in lots of vapor but still want to notice at least a little throat hit as well. 30/70 produces a smooth feeling that doesn’t overpower them when inhaling, and big clouds when exhaling. It’s the spot where most people feel they get the best of both worlds.
    • 50% VG/50% PG: (50/50) As we’ve mentioned, this is a good starting point for experimentation. There are quality exhales along with a perceptible, but not strong, bite on the inhale. Once, was the industry standard, but now 70/30 seems to be the norm.
    • 20% PG/80% VG: (20/80) This mix incrementally increases vapor production while slightly decreasing the throat hit delivered.
    • 100% PG (Max PG): Once quite common but not as popular anymore, e-juice with a 100% propylene glycol base has the strongest throat hit and best delivery of most flavors. However, the amount of vapor produced is noticeably less than with e-liquid that has a significant amount of vegetable glycerin.

    Other factors can play into your ultimate decision; for example, we’ve discussed the sweet VG flavor which can distort the taste of very delicate flavors. However, you may also find that the bite of a blend that’s heavy on PG works best to bring out the tartness of fruit flavors, while the thickness of VG can make creamy flavors feel like you’re inhaling a mouth full of delicious dessert. In any case, much of the fun of vaping is experimentation and discovery, and trying out different PG/VG ratios can be more enjoyable and less “nerdy” than messing around with voltage and resistance.

  • What You Need To Know About Diketones And E-Liquid Ingredients

    VapeCraft Inc presents,(1)

    Have you ever wondered how better off you really are by switching from regular cigarettes to the vaping? Well a quick Google search will tell you that vaping/e-cigarettes are 95% less harmful than tobacco according to a study carried out by the Public Health England[¹]. Great news! But of course, this isn't the full story. Even though vaping is widely regarded as the better option to ‘traditional’ smoking, it has been around for a relatively short period of time and there are concerns over some of the chemicals they contain. These chemicals are known as Diketones.(Note: not all e-juice contains diketones, some are diketone free). Be sure to check out our diketone free vape juice.

    If you’ve been vaping for a while you may have heard of diketones once or twice but have never really thought to look into it further until now. In this blog post, I want to explain what diketones are, the different types of diketones, whether you should be concerned and other ingredients found in e-liquid.

    What Are Diketones

    Diketones aren’t just something that is used in e-liquid, it is something that is found in the general flavoring industry. This is because it is used as an additive for buttery flavorings and creamy flavorings in food as well as in e-juice. Diketones are actually required by law to be tested for in food however it is not required by law to be tested in inhalation products. This is why many of you who vape find it difficult to find concrete information as to whether some e-liquids are diketone free.

    Diketones isn’t just one chemical however, it is the term used for a group of chemicals. The chemicals that are known as diketones are diacetyl, acetyl propionyl and acetoin. However it is known that acetyl propionyl and acetoin can sometimes also contain traces of diacetyl. I will go into each of these in more detail.

    Diacetyl

    Diacetyl is the most questionable out of the three and for good reason. In the 1990’s, it was found that workers in a popcorn factory contracted bronchiolitis after inhaling high amounts of diacetyl for a long period of time. Diacetyl is used as an additive to create the beautiful buttery flavour we get in our microwave popcorn. While levels of diacetyl are tested in food, nobody had realised before this incident that inhaling diacetyl could be cause of concern. Bronchiolitis is now known in laymen terms as “popcorn lung” because of this incident.

    While even the hardiest of vapers won’t inhale as much diacetyl into their lungs as popcorn factory workers, it is a harmful substance that is going straight into your lungs.

    Smoking vs Vaping

    Dr. Konstantinos Farsalinos' study found that many of the well-known e-liquid manufacturers had high levels of diacetyl and some even being above the safety limit set by OSHA. In recent times though, many e-liquid manufacturers have removed all flavors from their production that contain diacetyl.(All VapeCraft,Inc's juice is diacetyl free)

    A second(and newer) study was also conducted by the Harvard T.H. Chan School of Public Health[²] that showed that smoking tobacco resulted in inhaling 750 times more diacetyl than vaping e-juice.

    Keep in mind that Diacetyl isn’t in some e-juice at all, and a much higher amount of diacetyl can be found in tobacco cigarettes as seen in the chart below.

    diacetyl.harvard(1)

    Acetyl Propionyl and Acetoin

    The other diketones are acetyl propionyl and acetoin which aren’t as much of a concern as diacetyl but many vapers still try and avoid them in their e-liquid. After manufacturers realized the harm diacetyl can cause when inhaled, they looked for alternatives so they could still create creamy and buttery flavors. These alternatives came in the means of the diketones acetyl propionyl and acetoin. It has been found out recently though that these can actually ‘catalyze’ into a small trace of diacetyl either during the manufacturing process or even during the vaping experience.

    While these two diketones are considered to be safe for inhalation, many vapers try and avoid these ingredients when purchasing e-liquid. There has not yet been any scientific evidence as to whether acetyl propionyl and acetoin are harmful or not. As mentioned earlier on, vaping is a relatively new thing and so tests are still continuing to be done.

    Should You Be Concerned

    Due to the lack of scientific evidence surrounding acetyl propionyl and acetoin there is little cause for concern. The main cause of concern is with diacetyl which has proved to cause problems with lungs known as ‘popcorn lung’ which is irreversible. This doesn’t mean that you should stop eating your delicious buttery microwave popcorn though as diacetyl is safe for food consumption. It is only harmful when inhaling large doses of it and for a long period of time.

    While diacetyl has been found in some e-cigs and e-liquid, it is important to take into account that even then, you may be better off vaping than smoking traditional cigarettes because diacetyl is found up to 750 times more in cigarettes than in e-cigs. While there is a very minimal chance of contracting ‘popcorn lung’ from vaping, many vapers and manufacturers choose to stay clear. If you know of any companies that still use diacetyl let us know in the comments below, and we will update the thread with a list of companies.

    You will generally find that most well-known e-liquid manufacturers now don’t sell any e-liquid that contains diacetyl but you will still find manufacturers who will sell e-liquid containing acetyl propionyl and acetoin so as to be able to create popular flavors such as banana cream, butter and custard.

    What Is In E-Liquid

    E-liquid is what fuels your vaping device/e-cigarette and is what gives the flavor. It can also provide a nicotine solution to those who are just starting to switch from traditional smoking. E-liquid is what evaporates to create the vapor that is very similar to that of traditional cigarettes. It can come in many flavors and contain different ingredients. Those ingredients can include the diketones I have spoken about and also propylene glycol (PG) and vegetable glycerine (VG).

    PG or Propylene Glycol

    Propylene Glycol is nontoxic and is a flavoring found in foods, some ingredients in food coloring and even some medicines. It is an additive just like diketones for flavoring, but a nontoxic additive. It is usually recommended to have a blend of both propylene glycol and vegetable glycol for a much smoother flavor than if you were to have 100% PG.

    VG or Vegetable Glycerin

    Just like with propylene glycol, it is recommended that you blend both vegetable glycerine and propylene glycol as VG can be very hard to vape of if it is 100% strong. This is because VG is a thick vegetable based liquid so is harder to evaporate. It is quite sweet in taste and is nontoxic so makes for a good e-liquid ingredient.

    We will be publishing an in depth article on our blog soon about VG/PG ratios. Stay Tuned!

    Conclusion

    I think the main thing to point out is that only diacetyl has officially been found to cause lung problems when inhaled and that there is no evidence(yet) to show that acetyl propionyl and acetoin do the same. More and more research is being done by professionals on e-juice which you will always find out about here. For now though, be sure to avoid any e-liquids that contain diacetyl.
