Difference of PG and VG

As a vaper, you must be aware of the two main ingredients of any vape juice. PG or propylene glycol, and VG or vegetable glycerin, are the components that, together with nicotine, form e-liquids. When heated, they produce the vapor that we inhale. Most liquids use a combination of both substances. But what’s the main difference between Propylene Glycol vs. Vegetable Glycerin?

Although usually in varying degrees. Some vape settings, especially those designed for dry mouth-to-lung vaping, have limited airflow. So, they will work best with high percentages of PG. Although in cartomizers and tanks with a more open flow, there can be different PG/VG percentages.

Many vapers change the percentages depending on what they are vaping. It also depends on what kind of flavors you are using. Fruity or beverage flavors work best with PG. The sharpness of PG mixes well with the harshness of the aromas. Creamy or yogurt flavors mix well with high VG.

Since the high density adds the dessert style you are looking for. In short, it’s best to choose the ones you like best. Just remember to check that your device can handle the percentage you are going to use.

What Is Propylene Glycol (PG)?

Propylene glycol is a colorless, almost tasteless, odorless organic compound. It’s a hygroscopic, transparent oily liquid that’s miscible with water, acetone, and chloroform. It is from the hydration of propylene oxide. Propylene glycol is a small carbon-based molecule found in the alcohol family.

Along with more familiar compounds such as ethanol. Better known as the drinkable alcohol and isopropyl, better known as the disinfectant alcohol. It is perhaps the most similar of all to the ethylene glycol-based antifreeze. It also finds application as an aircraft de-icing compound. It is an environmentally friendly and non-toxic antifreeze for pets.

In most cases, however, propylene glycol is an effective solvent. It is a common ingredient in pharmaceuticals, cosmetics, and deodorant sticks. Propylene glycol is a colorless liquid with a slightly sweet taste and is noticeably more viscous than water. That means that it flows slowly, like syrup.

Propylene glycol is a relatively small molecule. According to the CRC Handbook of Chemistry and Physics, its molecular weight is 76.09 g/mol. The compound’s small size and structural similarity to drinkable alcohol make it very soluble in water. In fact, propylene glycol is hygroscopic. That means that it can extract water from the air and dissolve it. The propylene glycol molecule is considered stable.

Furthermore, it does not decompose over time. It does not react with air. But you have to be careful because it can be flammable.

How Is PG Made?

PG is added to a vape juice. Propylene glycol is produced synthetically in laboratories and may be derived from propylene oxide. It is extracted from different plants. That is why vape juice manufacturers are evolving their extraction methods. Like all other plant-derived substances, the methods are complex. Among them, it can be by steam or by co2. It all depends on the manufacturer.

The Uses Of Propylene Glycol

This ingredient is in thousands of cosmetic products as well as in various processed foods as a flavor additive and preservative. It is also in some medicines. It makes it easier for the body to absorb chemicals. In electronic cigarettes, it is to improve flavor and “smoke smoothness.” When propylene glycol is in antifreeze, instead of ethylene glycol, a toxic compound, it is a “non-toxic antifreeze.”

Predictably, many people are concerned that an ingredient used in antifreeze is also part of their food. Regulatory agencies also disagree. For example, in the United States, the FDA recognizes propylene glycol as a safe compound. Always at a concentration of up to 50 grams per kilogram. In Europe, on the other hand, the regulation says that no more than 3 grams per kilogram should be used. A big difference.

What Is Vegetable Glycerin (VG)?

Vegetable glycerin, also called liquid glycerin or glycerol, is natural alcohol. It is made from palm oil, coconut, and cottonseed oils. Because of its moisturizing and hypoallergenic properties, it is in the cosmetic and food industry. It is also used in home remedies for skin and hair.

Also known by the acronym VG, it has no harmful health effects, at least not proven. When heated, vegetable glycerin for vaping produces relatively large clouds. Not as dense as propylene glycol, though. And the sore throat hit is also more minor. But it does give liquids a sweetish flavor that many vapers appreciate.

As we already saw, liquid glycerin has a sweet taste. It is enjoyable, and you can take advantage of it to enhance the aromas of tropical fruits, drinks, and desserts. But this also has its drawbacks. If you use it in a high percentage, you must control the amount of sweet aroma. Otherwise, you could get a somewhat cloying flavor.

How Is VG Made?

Vegetable Glycerin (VG) is a natural mixing agent. Vegetable glycerin is made from palm or coconut oil and is a colorless liquid. It has no taste and can be dissolved in both water and alcohol. That to take advantage of its properties. The best thing about this ingredient is that it is hypoallergenic. So everyone can use it without putting the health of their skin at risk.

PG vs VG

The Uses Of Vegetable Glycerin

Vegetable oils glycerin is present in most gels and shampoos for its properties. But it also exists in many beauty products such as moisturizers that we can make in our bathroom and kitchen. We may not be able to make them as such at home.

  • Hand soap

The essential product containing glycerin is hand soap. It is also one of the easiest to make. So it can be a perfect activity to do with the little ones.

  • Mask

Thanks to its anti-acne and antibacterial powers, this ingredient can elevate that natural ingredient face mask. Such as lemon or avocado that moisturizes and nourishes the skin.

  • Hair mask or conditioner

The same goes for the hair ones, which we can also make by mixing argan oil, honey, and butter. That to nourish the ends.

  • Homemade moisturizing cream

It is for both face and body. For this, together with vegetable glycerin dissolved in water, we mix nourishing kinds of butter such as shea butter. Also, oils such as avocado oil make the cream more liquid and aromas. You can also add different active ingredients in boosters you have at home, like caffeine, Vitamin E, etc. Vegetable glycerin enhances its performance.

  • Lip balm

Although it is somewhat more complicated to make at home, it is also possible. Glycerin helps the regeneration of the skin of the lips in the right concentration, that is, not in large quantities.

What Is The Best PG/VG Ratio In Vaping Juice?

Each person is a world. You can reach your preferences by choosing the PG/VG percentage that best suits your taste.

If you are looking for a good throat hit and intense flavor, a high PG level is best for you. The throat hit is something that ex-smokers tend to prefer. So if you’ve gotten into vaping to quit smoking, you should tend towards higher PG levels. It also goes well with tanks with a narrower airflow. These mimic the mouth-to-lung style of vape reminiscent of smoking.

Whether you prefer a smoother throat hit, longer puffs, or denser clouds is different. Here liquids with high VG concentrations are the best. They do lose some flavor, but they can be fixed by increasing the wattage of your device. Also, make sure you are within the wattage limits of the atomizer.

Which One Is Better, PG Or VG?

PG is less dense than VG. So it provides a better throat hit but makes the vapor plumes comparatively less dense. But none is better than the other. PG vs. VG is an equal summary. In general, we can say that fruity or beverage flavors work best with PG since the sharpness of this component blends well with the harshness of the aromas. At the same time, creamier or yogurt flavors work better with VG.

As we have said before, every user has their preferences, and no one is better than another. That’s the beauty of the art of vaping. It’s so flexible that any user can adapt it to how they feel best and how it works best for them. Which component works better for you, VG or PG?

Final Thoughts

The market for vape liquids or e-liquids is growing day by day, in the same way, that the art of vaping innovates with time. For the same reason, it is super common to see new terms and words appearing all too often. If you are a beginner, you probably feel overwhelmed by this situation. But if you are an expert, you will already know about the constant change in vaporizers, also with the world of electronic cigarettes.

PG and VG are two abbreviations that help identify two components that are part of the composition of liquids. Most vape liquids use a combination of nicotine and these components, which can vary in varying degrees. Some devices may even work better with different compositions of these elements.
