Why is vegetable glycerine used in Vapes?

What is Vegetable Glycerine?

Vegetable glycerine, often abbreviated as VG, is a natural substance derived from vegetable oils. It is commonly used in e-liquids as a base ingredient due to its ability to produce thick vapor clouds when heated. VG is odorless, colorless, and has a slightly sweet taste derived from vegetable oils or fats making it an ideal carrier for flavorings in e-liquids. It is thicker in consistency compared to propylene glycol (PG), another common e-liquid base ingredient, which contributes to its role in creating dense vapor. VG is generally considered safe for consumption and is widely used in food, pharmaceuticals, and personal care products in addition to vaping also used used in food production as a sweetener and preservative, with no calories and not metabolized by the body like other sugars.

Vegetable Glycerine in Vapes

Vegetable glycerine, commonly known as VG, plays a crucial role in the composition of e-liquids used in vapes. As one of the primary base ingredients alongside propylene glycol (PG), VG contributes to the overall vaping experience in several ways. It serves as a carrier for flavorings and nicotine, helping to deliver the desired taste and throat hit and contributes to a smooth vapor and distinct mouth feel when vaping. VG is a humectant that attracts water, making it a great solvent for flavorings

One of the distinguishing characteristics of VG is its ability to produce dense vapor clouds when heated. Vapers who enjoy voluminous clouds often prefer e-liquids with higher VG concentrations. Additionally, VG tends to impart a slightly sweet taste, which can enhance the flavor profile of e-liquids, particularly those with fruit or dessert flavors.

While VG is generally considered safe for consumption, some individuals may experience sensitivity or allergic reactions to it. Vapers with PG allergies often opt for e-liquids with higher VG ratios to avoid potential adverse effects.

Vegetable Glycerine vs Propylene Glycol

Vegetable glycerine (VG) and propylene glycol (PG) are two primary base ingredients commonly used in e-liquids, each with its unique characteristics.

Vegetable Glycerine (VG):

  • VG is a natural substance derived from vegetable oils.

  • It has a slightly sweet taste and is thicker in consistency compared to PG.

  • VG is known for its ability to produce dense vapor clouds when heated.

  • It contributes to the smoothness of the vape and can enhance the overall flavor profile.

  • VG is less likely to cause throat irritation and is preferred by vapers who prioritize vapor production.

Propylene Glycol (PG):

  • PG is a synthetic compound commonly used in food and pharmaceutical products.

  • It has a thinner consistency and is virtually odorless and tasteless.

  • PG carries flavorings more effectively and provides a stronger throat hit, similar to smoking traditional cigarettes.

  • It is less prone to causing buildup on vaping equipment and coils.

  • PG is favored by vapers who prioritize throat hit and flavor clarity.

  • VG is a thickening agent, while PG is a solvent

  • PG carries flavor better, but can cause dry mouth and upset stomach, whereas VG does not have these side effects

  • VG is more suited to advanced kits and Sub Ohm devices, while PG is better for bold flavours and a smooth, subtle vaping experience

Benefits of Vegetable Glycerine E-Liquids

  • Dense Vapor Production: VG is renowned for its ability to produce thick, voluminous vapor clouds when heated. Vapers who enjoy impressive vapor production often prefer e-liquids with higher VG concentrations.

  • Smooth Vaping Experience: VG contributes to a smooth and velvety vaping experience, providing a pleasant sensation on the inhale and exhale. Its thicker consistency adds to the overall mouthfeel of the vapor. Provides a range of benefits compared to PG, including a smoother vaping experience and larger vapour clouds

  • Enhanced Flavor: VG has a slightly sweet taste, which can enhance the flavor profile of e-liquids, particularly those with fruit or dessert flavors. It serves as an excellent carrier for flavorings, resulting in a more enjoyable vaping experience.

  • Less Throat Irritation: Compared to propylene glycol (PG), VG is less likely to cause throat irritation or sensitivities in some individuals. Vapers with PG allergies often opt for e-liquids with higher VG ratios to minimize discomfort. It is considered a safer alternative to PG, with no known long-term risks associated with its use in vape juice

  • Versatility: VG is compatible with various vaping devices and coil configurations, making it suitable for both beginner and advanced vapers. It can be used in pod systems, sub-ohm tanks, rebuildable atomizers, and more. Can be used in a variety of ratios with PG to achieve different vaping experiences

Safety Concerns and Side Effects

Vegetable Glycerin is recognised as a safe ingredient for use in foods, pharmaceuticals, and cosmetics, with no research to suggest it has caused any health issues or side effects when used in vapes. However there are potential risks associated with vaping VG include inflammation of the lungs due to long-term use, but this is still less harmful than smoking cigarettes. Some vapers have experienced the following side effects.

  • Dehydration: VG has hygroscopic properties, meaning it can absorb moisture from the surrounding environment. Vapers may experience mild dehydration if they do not adequately hydrate while vaping high-VG e-liquids.

  • Allergic Reactions: While rare, some individuals may experience allergic reactions to VG, resulting in symptoms such as skin irritation, itching, or respiratory discomfort. It's essential to monitor for any adverse reactions and discontinue use if symptoms persist.

  • Coil Buildup: VG is thicker in consistency compared to propylene glycol (PG), which can lead to faster buildup on coils and vaping equipment. Regular cleaning and maintenance of vaping devices are recommended to prevent performance issues.

  • Reduced Flavor Intensity: High-VG e-liquids may result in slightly muted flavor compared to e-liquids with higher PG concentrations. Vapers who prioritize flavor clarity may prefer e-liquids with a balanced VG/PG ratio.

  • Increased Cloud Production: While desirable for cloud-chasing enthusiasts, the dense vapor clouds produced by high-VG e-liquids may be perceived as excessive in certain environments or social settings. Vapers should be mindful of their surroundings when vaping in public spaces.

    You can Minimize potential side effects by vaping at lower temperatures and choosing a good quality VG e-liquid.

Conclusion

In conclusion, vegetable glycerine (VG) serves as a fundamental component of e-liquids, prized for its ability to enhance the vaping experience in various ways. Notably, VG is renowned for its capacity to produce dense vapor clouds, appealing to vapers who prioritize impressive vapor production. Additionally, its smooth and velvety texture contributes to a pleasant sensation on the inhale and exhale, enriching the overall vaping experience. VG's slightly sweet taste further enhances the flavor profile of e-liquids, particularly those with fruit or dessert flavors, making vaping more enjoyable. Furthermore, VG's compatibility with a wide range of vaping devices and coil configurations ensures its versatility, catering to both beginner and advanced vapers alike. However, it's essential for vapers to be mindful of potential side effects and safety concerns associated with VG, such as dehydration and allergic reactions. Overall, vegetable glycerine is utilized in vapes to provide vapers with a satisfying and enjoyable vaping journey characterized by dense vapor production, smoothness, enhanced flavor, and versatility.
