Vape Juice Ingredients: All You Need to Know

May 29, 2023


Vaping has become increasingly popular in recent years as an alternative to traditional smoking. Whether you're an experienced vaper or just starting, understanding the ingredients that make up your vape juice is crucial. In this in-depth article, we will take a deep dive into the core components of e-liquids, including propylene glycol, glycerol, flavors, and more. By gaining insights into the ingredients of vape juice, you'll be able to make informed choices and fully appreciate the intricate world of flavors and vapor clouds.


Main Ingredients of E-liquids

Now that we understand the importance of vape juice ingredients, let's find out the answer to what is in vape juice, and explore the main components in more detail:

Propylene Glycol

Propylene glycol (PG) plays a fundamental role in juice vape ingredients. This versatile liquid, often referred to as PG, serves as a base that contributes to the overall composition of vape juice. It is colorless and odorless in nature, ensuring that it doesn't interfere with the flavors added to the e-liquid.

A key benefit of propylene glycol is its ability to provide a smooth consistency to vape juice. When combined with other ingredients, PG ensures an even distribution of flavors throughout the e-liquid, enhancing the overall vaping experience. Additionally, propylene glycol contributes to the throat-hit sensation, which mimics the feeling of smoking traditional cigarettes. This aspect is particularly valued by individuals who are transitioning from smoking to vaping and seek a familiar sensation.

The low viscosity of propylene glycol allows for efficient vaporization, ensuring that the e-liquid is effectively transformed into vapor upon heating. This quality is crucial in providing vapers with a satisfying vaping experience, as it enables smooth inhalation and the production of flavorful vapor clouds.


Glycerol, also known as vegetable glycerin (VG), is another essential component of vape juice that contributes to its unique characteristics. Derived from vegetable oils, VG is a thick and slightly sweet liquid that significantly impacts the vaping experience.

One of the primary functions of glycerol is to produce dense vapor clouds, which are visually appealing and sought after by many vapers. Compared to propylene glycol, glycerol has a higher viscosity. This thicker consistency contributes to the creation of thick and satisfying plumes of vapor that many vapers find desirable.

In addition to its role in vapor production, glycerol enhances the smoothness of the vapor, creating a more enjoyable inhalation experience. The slightly sweet taste of VG also adds depth and richness to the overall flavor profile of the vape juice. As a result, glycerol plays a crucial role in balancing and enhancing the sweetness of various flavors. 

Note: A blend with the combination of PG and VG is substantially smoother than a base that is 100% PG.

The RELX Pod takes this aspect seriously by utilizing high-quality and safe ingredients in their vape juice formulations. The core components of its vape juice include propylene glycol (PG) and glycerol (VG), providing a smooth consistency and efficient vaporization.  

Flavors, etc.

Flavors are at the heart of vape juice, offering vapers an extensive range of tastes to choose from. Vape juice flavors allow individuals to customize their vaping experience based on their personal preferences and cravings. Whether someone prefers the familiar notes of traditional tobacco or menthol, the vibrant burst of fruity combinations, or the indulgent satisfaction of dessert flavors, there is a vape juice flavor available to suit every palate.

These flavors are carefully crafted using high-quality, food-grade ingredients that have been specifically formulated for inhalation. Manufacturers employ advanced techniques to ensure that the flavors are well-balanced, delivering an enjoyable and consistent taste when vaporized.

Now, with RELX Pod, vapers can explore an array of options, ranging from classic and time-honored choices to innovative and experimental blends. This diversity allows individuals to find their preferred flavors and create a vaping experience that resonates with their unique taste preferences.



To find out what are the ingredients in vape juice and the details of the ingredients is essential for any vaper. In this blog, we've explored the main components of e-liquids, including propylene glycol (PG), glycerol (VG), and flavors. By gaining insights into these ingredients of juice in vape, you can make informed choices and fully appreciate the intricate world of flavors and vapor clouds. So, embrace the fascinating realm of vape juice ingredients and embark on a flavorful vaping adventure right now!



What are safe ingredients for vape juice?

Propylene glycol (PG) and glycerol (VG) are often considered safe ingredients for vape juice. PG is a non-toxic flavoring ingredient with a faintly sweet taste which is frequently used in food products or medicine. It can be used in your vape on its own, but a combination of PG and VG is usually more desirable since it is significantly smoother than a base that is 100% PG.

What makes vape sweet?

Vape juice gets its sweetness primarily from the addition of sweeteners such as sucralose and ethyl maltol. The difference between sucralose and ethyl maltol is that adding the former to your e-liquid is just like putting some sugar into it, while the latter emphasizes and brings out the natural sweetness. Other common artificial sweeteners include stevia, erythritol, etc.

Is vegetable glycerin safe to vape?

Vegetable glycerin, a key ingredient in juice in the vape, is generally considered safe for vaping. Derived from vegetable oils, it produces thick vapor clouds and adds a slight sweetness to the vape experience. While research on long-term effects is ongoing, current evidence suggests minimal risk. However, individual sensitivities may vary, so resp
