When it comes to electronic cigarettes and their e-liquids, which can also be referred to as e-cig juices or e-juices, you have two primary choices: propylene glycol based e-liquids or vegetable glycerine based e-liquids. Both of these types of e-liquids produce high quality vapour, but there are differences in the type of vapour that’s produced, as well as the effects that they have on the vaper.
Rest assured that both vegetable glycerine (VG) and propylene glycol (PG) e-liquids are completely safe for use with your favourite e-cig devices. But if you want to learn which type of e-liquid will produce the vaping results that you desire, you should get to know the pros and cons that are associated with each of these two main base ingredients.
Continue reading to learn a bit more about PG e-liquids, in particular.
What is Propylene Glycol?
Put simply, propylene glycol is an odourless, clear liquid that also has no flavour of its own, making it an ideal base in which nicotine and flavouring can be added to enhance your vaping experience.
This ingredient is created by adding water to propylene oxide. It’s found in a variety of everyday items, from cosmetics and medications, to animal feed and human food. Therefore, it’s deemed safe for consumption even in e-liquids that are used by vapers around the world.
How is Propylene Glycol Used?
In addition to serving as an effective base ingredient in e-liquids, propylene glycol is often used as a stabiliser. It can be utilised to maintain moisture levels in food as well. It’s even used on an industrial scale within the paint and plastic industries.
Because this ingredient is used in de-icing products and non-toxic antifreeze, there have been some concerns raised about its safety. But rest assured that propylene glycol is actually added to anti-freeze to make it less toxic in the event that anti-freeze is accidentally ingested. It isn’t a harmful ingredient, nor is it the main ingredient in anti-freeze, so you needn’t worry that you’re consuming anti-freeze when you vape with an e-liquid that contains propylene glycol.
Why is Propylene Glycol Used in E-Liquids?
You may be wondering why propylene glycol is such a popular ingredient used in e-cig liquids. Basically, it has great water-retaining properties, making it ideal for delivering atomised medicine through inhalers and nebulisers. Asthma sufferers, for example, can take their medicines in this manner.
But in an e-liquid, PG allows atomisation to occur at a much lower temperature than what is required in tobacco smoking. PG helps deliver the right dose of nicotine to the vaper in a more effective manner than vegetable glycerine can when it’s inhaled through an e-cig device.
How Does Propylene Glycol Affect Vaping?
Propylene glycol produces a unique vaping experience that’s quite different from that which is created by vegetable glycerine.
This ingredient is perfect for vapers who prefer a thinner cloud of vapour in place of a thick cloud. This is because propylene glycol is thinner in consistency than vegetable glycerine, which produces thicker vapour clouds. It really depends upon your personal preference whether you like thinner or thicker vapour clouds. Either way, you’re still getting a delicious amount of flavour from your e-liquid and the adequate amount of nicotine that your body craves.
Because it’s thinner in consistency, PG is also known for extending the life of your e-cig’s cartridge.
Propylene glycol is popular in e-liquids because it doesn’t have a flavour of its own, so vapers may find that e-liquids containing this ingredient as a base produce truer flavours.
Just be aware that PG is associated with allergic reactions in some people. The reactions can range from tingling in the throat to irritations in various parts of the body. If you’ve tried PG e-liquid but you had an allergic reaction, it’s best to try an e-liquid with vegetable glycerine or PEG 400 as the base instead.
In addition to the potential for allergic reactions, propylene glycol may also cause your mouth and your throat to become quite dry if you vape a lot. This is because it’s able to produce a powerful throat hit that’s very similar to the throat hit you get from smoking regular tobacco cigarettes.
You may find e-liquids that combine both propylene glycol and vegetable glycerine as the base. This creates a balance between the consistencies of both ingredients, and many people actually prefer to get the best of both ingredients by purchasing e-cig juices that contain both.
Safe and Effective for Vaping
As you can see, propylene glycol is an ingredient that’s both safe and effective when it comes to using it in electronic cigarettes to produce a delicious, flavoured vapour. Whenever you purchase an e-liquid, just be sure to look for products that are manufactured under strict quality control standards. The higher the quality, the safer and more effective the e-liquid will be.
