Propylene Glycol and Vegetable Glycerin explained

PG – Propylene Glycol

PG solution is an important factor in electronic cigarette juice flavoring. Mt. Baker Vapor uses USP grade Propylene Glycol which is FDA approved for uses such as: candy, manufacturing, dairy products, beverages and even pharmaceuticals. Propylene Glycol is commonly shown in the media as being used in products such as antifreeze, is this true?

The short answer is yes, glycol is a component found in generally “environmentally friendly” cooling equipment as it does have many purposes. The truth is, antifreeze is NOT a component whatsoever in electronic cigarette juice though. However, the media may portray this to distort the perception of the electronic cigarette industry.

USP and FDA approved propylene glycol can be purchased in large volumes to make ice blocks, manufacture ice cream and is used globally at wineries, distilleries and other beverages manufacturing companies. It is odorless, colorless, flavorless, and in our own federal governments’ terms, “harmless”, as it is safe for use in medications per the Food and Drug Administration.

At Mt. Baker Vapor, we use the same USP, FDA approved “food grade” Propylene Glycol as a base solution with other FDA approved food flavoring concentrates to create nicotine juice.
Our house blend consists of VG as well, or Vegetable Glycerin and you can also use 100% VG as base for e-juice.

Let’s also examine Vegetable Glycerin, another FDA approved solution found in electronic cigarette juice. In a further topic we can discuss the reasons why we recommend our proprietary house blend of 80% PG to 20% VG in our e-juices. But for now, we just want to get some facts out about what is our great e-juices.

VG – Vegetable Glycerin

    I came to this page for some information on your VG/distilled water mix. There is no info on the VG or that mix. I have experienced sensitivity to the PG at 50/50 and was hoping for some information on other options. I do know that VG produces more vapor but less flavor and am torn between bumping down to 20/80 or the h2o mix…. more info on these things would be awesome!

      Very sorry this article is not yet complete and we are working on it.

    • Gabe says:

      Ive been vaping for almost 4 years. And not to tell a long story. I make my own juice by purchasing a supper high nicotine mix then mix with my diluted mix of PG/VG. I’ve never used water as it nulls the vapor. But I have used strait VG this is a good way, but it is very sweet and kind of hot. My cartamizers don’t last as long. But I think if you wash it daily it will greatly reduce the gump and assist in longevity. I hope this helps.

  • veryhappyvaporizer says:

    I have tried 4 other brands……I’m using the Smok Dual coil, this one is a WINNER!!!! I didn’t think I could make the change after 35 years of smoking….finally very, very happy. Best throat hit, best menthol E-juice flavor and long lasting. YAY! I have reordered more supplies and will be continue to be a customer.

  • Cait says:

    So this is a somewhat unrelated comment… but I noticed in one of your juice descriptions that it says to let the juice steep… what does this mean? I am relatively new to vaping and aim to educate myself. I’m happy to say that after being an on again off again smoker for 6+ years I’m down to using the lowest or even zero nicotine thanks to electronic cigs!!

  • Art G says:

    Hi James-

    I’ve been buying my e-juice exclusively from MBV since I started Vaping in April 2012 and ONLY use MBV because your quality, custom blends and fast shipping make this place one stop shopping. I’m curious about the tank cracking reports I’ve read recently. I use a Joye e-GO-C “B” Type system and have used ONLY MVB e-juice for well over a year in my e-GO-C plastic tank system and virtually only those flavors (Venom, Hawk Sauce, Cinnamon Blends, etc. ) that are supposedly cracking tanks and have NEVER ONCE HAD THIS HAPPEN?? Is it just certain brands, styles or sizes of the plastic tanks that crack?

    Just curious. And thanks for making a great product! It’s very hard to find anyone else that will customize e-juice like MVB.

  • Carrington C says:

    I am fairly new to vaping (only couple months) and MBV is the first place I have seen or heard the terms PG and VG and the different mixtures available. What is the difference between the percentage mixtures? I just started using my first juices ordered from MBV and the flavor is amazing but it seems the vapor is not as thick as I would have hoped it would be. I got the 80% PG and 20% VG mixture.

    • We have several blends at MBV! Our house blend = 80% PG/20% VG. A 50% PG/50% PG blend. A 65% PG/35% VG blend. A 20% PG/80% VG blend. A 70% VG/30% Distilled Water blend. A 100% PG blend. A 100% VG (Max VG) blend. The higher the amount of VG the more vapor production. The lower the amount VG the lower the vapor production. If you aren’t like the vapor production the 80/20 blend I would recommend trying either the 65/35 or 50/50. IF you still want more after trying those blends I’d try the 20/80 and MAX VG blends. I love vapor, so I usually vape 20/80. Hope this helps. Let’s me know if you have any more questions.

      • Ethel Isaacs says:

        Hi Katrina , Thanks for your recent reply . This has cleared a lot up for me . As a new Vaper , I’ve ordered a few times from MBV and knew I was doing something wrong …. I was getting the taste but not the vapor … I thought possibly my battery was default … I also order for my Oldest Grandson who got me started on this. I was just about ready to give up …… and continue with my 43 year habit of smoking cigarettes …..I’ve already lost my priviledge of seeing my granddaughter and do not want that to happen with my other Grandson …..All because of the smell of cigarettes on me ….. So I’ll give it another try and order the 20/80 ……. …..

      • Johnny says:

        I’m so glad I read this . Just ordered my first Max vg and haven’t tried it like that before. I think I’ll just stick to 50/50 .ordered my first box MOD the other day from here and excited about it. .but this clears up my questions on the subject for the e juice. Ty for posting this

  • Wendy Thomas says:

    Do you get a better flavor with with higher VG or PG. Or does the nicotine level make a difference. I think I am getting less flavor since I lowered my nic level to 6. I have not smoked tobacco flavors in over 2 months.

    • PG carries the flavor. VG dampens the flavor. So in essence the higher the PG the more flavor the higher the VG the less flavor. Hope this clears this up. Let me know if you have any other questions.

  • Tyler says:

    Hi I’m having dome trouble with my tanks not seeming to want to wick properly. They work great for a second then it seems like They just aren’t pulling in enough juice and the cartridge starts to taste burnt rather quickly. someone said it may be from too much VG content making the juice thicker and harder to absorb. I Don’t know anything about steeping and actually this is the first time I’ve ever heard of it. Also I’m wondering If Maybe leaving the juice in my car while I’m at work is causing it to get too hot and Maybe thicken up? I Don’t know I’m fairly new at all this and just Don’t know where to find quality information. I’m wondering If there isn’t just a comprehensive users guide somewhere that you could direct me too as well as letting me know If my own ignorance and leaving it in my car is causing my problems. I’m 5 months in with No cigarettes and absolutely Love the vaping thing. But I’ve just been having so much trouble lately keeping everything working right and there’s nothing more frustrating than getting to work and having that foul burnt taste of a Carboniferous or Whatever they’re called That’s burnt up and tasting terrible. besides the fact that this is such a money saver If I could just get it right. Lol. Thanks for any help.

    • Since it sounds like you may be having one of several of problems.

      If you juice is starting to taste burnt you may be vaping at to high of a voltage or wattage. I would recommend turning it down.

      Depending on hot your car is it maybe affecting your juice. For example if you are keeping them in your dash you may be exposing your juice to to much light which causes photo-dehydration and would make the juice tastes terrible. Also you may be overheating your juice would also cause the thickening and terrible taste.

      The more VG the thicker the juice. If you want you juice to be thinner I would recommend lowering the VG and upping the PG. Our house blend is 80PG/20VG. Personally. I like the 50VG/50PG blend.

    Hello there! This blog post could not be written much better!
    Looking at this article reminds me of my previous roommate!
    He always kept talking about this. I am going to send this article to him.

    Pretty sure he will have a great read. Thank you for sharing!

  • Paul Benedetti says:

    I got a free juice of rainbow roundies how can I buy more of this its a life changing flavor

  • Tim Rowan says:

    Will the VG/PG blend work to thin marijuana wax?

  • Alex Gilley says:

    Does “throat hit” pertain to the PG/VG blend? Or is it nicotine? Or flavor? I have found that I can vape certain e juices from a cartomizer just fine, but when I drip it on my atomizer it hits my throat like a freight train. What is the best way to achieve a super tasty, super smooth vape with no throat hit?

    • Alex, throat hit comes from both PG and nicotine. Most people can vape a much higher nicotine strength when using a tank but will drop down when dripping. To achieve a great smooth vape on a dripper I would recommend a high VG ratio like max VG or 20/80 with a nicotine strength of either 0,3, or 6 mg/ml.

  • Alex Gilley says:

    Okay awsome! Thank you.

  • Bill says:

    Cutting the nicotine level drastically will mean you will not be getting your normal nicotine fix. It is best to try cutting the PG level first and hope that smooths out your vape.

    You may need to take smaller hits when dripping – as well as avoiding lung hits.

    You can also try reducing the voltage/wattage, if that is possible with your PV. If it is a mechanical MOD then the power depends primarily on the resistance of the coil. If that is the case, try using a somewhat higher resistance coil, assuming one is available.

    As a last resort, you could try adding a few percent of distilled water to the juice.

    When you try any/all of the above, mix up small batches – just a few milliliters at a time.

    If you get a satisfactory vape with a tank, then you can get one with a dripper. It just takes some experimentation.

  • Rick James says:

    pg= thinner+less vapor and good flavor
    vg= thicker+a lot of vapor with significant flavor loss
    two things to mention are that with a dripper vg carries more flavor than in a tank and than you can thin down vg with distilled water to allow it to wick but it will lose some vapor reproduction

    • Thank you for the feedback,you are a master of your trade. This blog was normally meant for beginners starting off and just learning. So we opted out from adding that on the blog, just because it might confuse them when they hear about dripping. But seriously thank you for catching that, we always love our community and helping us out. Have a wonderful week!

  • Kenneth says:

    Hey guys, i was wondering: Can I use food grade vegetable glycerine in my dripper without the chemical compounds changing and becoming harmful. I subohm at .23, so that’s why i am wondering. Juice prices are killing me. Lol

  • John M says:

    I have been vaping for a few years, and also have my own e-juice company starting up. i ordered something like 700ml of juice from here and it was absolutely garbage. I now know that this is a result of using cheap product. I was extremely disappointed with my order and literally gave all of the juice away. Giving it away for free was even a tough task. That was the first and last order I have ever placed with MBV.

  • stacy says:

    I just want to know what EXACTLY what to order that has the most flavor with the nicotine level as light.

    • Unfortunately we aren’t able to tell you what will work for you exactly. IT’s all a matter of personal preference from the flavor level to the amount of throat hit you get from the e-juice. PG holds the flavor, but tends to have a stronger hit on your throat. VG softens the flavor but creates a lighter hit to the throat. I would suggest starting with a 50/50 blend, and then adjusting if you need to based on those things. If you enjoy the throat hit of the 50/50 but just want more flavor, remember you can always add extra flavor shots as well.

  • Scott says:

    So, I think I’ve figured out the rule of thumb for throat hit, but I haven’t found a one-paragraph outline of the effects of PG, VG and nicotine on your website.
    Without confusing the issue with water, is it like the following:
    (For a given level of flavoring and nicotine)
    Lower VG = lower vapor production and Increased throat hit.
    Higher VG = higher vapor production and lower throat hit.
    (PG is the opposite)
    For a given PG/VG ratio, raising nicotine lever raises throat hit.

    Does that make sense or do I have something backwards?

  • robert renner says:

    new to vaping 1st try and choked almost to death is it something I am doing or is it the mix bought it from MBV and is is 50/50 was free sample’s with no Nic from what i read.

    • Tim Mechling says:

      Make sure your juice is steeped, your coil is wicked properly, and your airflow is set right. Our customer service department can help troubleshoot any issues. If you’re looking for hands-on help, vape shops are an excellent resource for helping with setups!

    • Trish says:

      You have to get used to vaping. My first week I almost choked to death too, so I had to lower the voltage down on my kangertech mini, and after the first week it became easier. I just don’t like the burn in my throat now, so I’m trying the 80vp/20pg that seems to help alot but still have the burn but not as bad, I’m using the 5 nicotine, so I’m thinking the nicotine is what’s giving me the throat burn. Going with zero nicotine and 80/20 next time, I hope I can get rid of the burn that way. I love vaping, and I don’t ever want another nasty cigerette 😉

  • staila says:

    I’m new on this and I want to make my own juice. Can you help me out?
    Where exactly did you buy the PG and VG? I Bought VG at Walmart but I can’t find the PG. Can you send me a pic of the bottle?

  • Stephen says:

    I don’t notice much flavor loss with max VG, but greatly prefer the smoothness.

  • home says:


  • Azvaper says:

    Hi! I was looking for a more affordable eliquid than what I’ve been vaping- (Menthol Ice by Halo)- and I was wondering if this site offers something similar, and also how the PG/VG ratio would compare to it? Thanks!

  • Thanks to all for share useful comments…
