What is Propylene Glycol?

Vaping has taken the world by storm, captivating both smokers and non-smokers with its mesmerising vapour clouds. But have you ever wondered what makes these clouds so impressive? The secret lies in the unsung hero of vaping – propylene glycol.

This colourless and odourless liquid has become an essential ingredient in e-liquids, fueling the creation of those billowing plumes that envelop vape enthusiasts everywhere. Whether you're a vaping aficionado or simply intrigued by this modern phenomenon, join us as we delve into the fascinating role propylene glycol plays in making your cloud-chasing dreams come true.

What is propylene glycol?

Propylene glycol is a synthetic compound that belongs to the alcohol family. It is a clear, colourless, and viscous liquid with a faint sweet taste.

The role of propylene glycol in vaping

Propylene glycol (PG) is a key ingredient in e-liquids used for vaping, along with vegetable glycerine (VG). PG serves multiple roles in the vaping experience. Firstly, it acts as a carrier for the flavour concentrates present in the e-liquid. It has a low viscosity and helps distribute the flavours evenly throughout the liquid, enhancing the taste and aroma when vapourised.

Secondly, propylene glycol contributes to creating vapour clouds during inhalation. When heated, PG produces a dense vapour that mimics smoke, providing users with a satisfying visual experience similar to traditional smoking. This aspect of PG is particularly important for those who have recently switched from smoking cigarettes to vaping and are looking for a comparable sensation.

Lastly, propylene glycol contributes to the throat hit experienced by vapers when inhaling. It provides a slight tingling sensation on the throat, which can be adjusted based on personal preference by varying the ratio of PG to VG in an e-liquid formula.

Alternative to propylene glycol in vaping

If you are looking for an alternative to propylene glycol (PG), vegetable glycerine (VG) is an excellent option. Typically, most vapers use a blend of 50/50 or 70/30 but for individuals who have a sensitivity or allergy to PG, using 100% VG can be a suitable replacement.

However, it's important to note that while VG may be a suitable alternative, it does have some drawbacks. Due to its thick consistency, VG can cause clogging issues in certain types of vape tanks or coils. Additionally, because VG produces denser vapour clouds, it can sometimes result in reduced flavour intensity compared to PG-based e-liquids.

Other uses of propylene glycol

Propylene glycol is found in several other everyday products. One of its main applications is in personal care products such as lotions, creams, and cosmetics. Its ability to act as a humectant helps retain moisture on the skin's surface, making it an excellent ingredient for hydrating skincare formulations.

Another common use of propylene glycol can be found in food and beverage industries. It is often used as a solvent and preservative in various food products like ice cream, salad dressings, and baked goods. Additionally, it serves as a carrier for flavours and colours used in beverages like fizzy drinks and energy drinks.

Propylene glycol is used as an ingredient in certain medications and pharmaceutical preparations due to its properties that enhance drug absorption into the body. As a result, it can be found in oral solutions or topical medications such as ointments or creams.
