The taste of e-cigarettes depends on the e-cigarette oil. The quality of e-cigarette oil often depends on its two core components - plant glycerin (VG) and propylene glycol (PG). These two components not only affect the taste of e-cigarettes, but also directly related to the production of smoke, the intensity of the taste, and the feeling of the throat. So, let's go back to basics and look at what PG and VG really are, what they do, and how their proportions differ.

What are VG and PG?

Vegetable glycerin, or VG, is a colorless, odorless, viscous liquid derived from vegetable oils. It is commonly used in food and cosmetics as a moisturizer and thickener. In e-cigarette oil, the role of VG is mainly reflected in the following aspects:

• Amount of smoke: VG is a key component in producing large amounts of smoke. It can make electronic cigarettes produce rich steam when inhaled, bringing a stronger visual effect, suitable for users who like the "smoke bomb" effect.
• Taste experience: VG has a sweeter taste and can provide a smoother inhalation experience, suitable for users who prefer sweetness and a softer taste.
• Laryngeal sensation: VG's stimulation of the throat is relatively small, and it does not produce a strong throat tingling sensation when inhaled, which is suitable for users who are more sensitive to laryngeal stimulation.

Propylene glycol (PG) is a colorless, odorless, low-viscosity liquid commonly used in the food and pharmaceutical industries. The role of PG in e-cigarette oil is also very important:

• Throat Hit: PG provides e-cigarettes with a more intense throat hit, which is similar to the inhaling sensation of traditional cigarettes and is ideal for users who want to simulate the traditional smoking experience.
• Taste transmission: One of the roles of PG in e-cigarette oil is to help the transmission of taste. Compared with VG, PG can better highlight the aroma and flavor of the tobacco oil, so that users can taste the flavor of the tobacco oil more clearly.
• Amount of smoke: PG produces relatively little smoke, but its clear taste and strong throat punch make it the first choice for many smokers.

The effect of the ratio of VG to PG on the experience of e-cigarettes

The ratio of VG to PG of e-cigarette oil determines the difference in smoking experience. Common proportions are:

• High VG ratio (70VG/30PG, 60VG/40PG, etc.) : Suitable for users who like large smoke, while providing a smoother inhalation experience. Suitable for users using high-power electronic cigarette equipment.
• High PG ratio (50PG/50VG, 60PG/40VG, etc.) : suitable for users who pursue a strong sense of laryngeal impact, closer to the experience of traditional cigarettes. For the use of smaller power electronic cigarette equipment, the higher PG ratio of the liquid can also provide a better taste experience.
• Balanced ratio (50VG/50PG, etc.) : suitable for those who like the smoke effect, but also want to have a certain feeling of throat. It provides a balance between the taste, the amount of smoke and the pounding sensation in the throat.

Choose the right ratio of VG to PG for you

To choose the right ratio of VG to PG, firstly consider the following points:

• Personal taste: If you prefer thick smoke and sweet taste, you can choose a high VG ratio of the fume; If you prefer a clear taste and a strong throaty sensation, you can choose a high PG ratio of the liquid.
• Smoking habits: If you switch from traditional cigarettes to e-cigarettes, you may prefer the higher PG liquid because it can bring a cigarette-like throat punch. For those users who pay more attention to the cloud effect, it is recommended to choose a high VG smoke oil.
• Device compatibility: Different e-cigarette devices may have different adaptation requirements for the ratio of VG to PG. High-power equipment is usually suitable for high VG proportion of soot, while low-power equipment is more suitable for higher PG proportion of soot.

safety

E-liquids are always sold in child-safe bottles to prevent children from accessing these liquids. When discussing the safety of e-liquids, it is most important to focus on nicotine. The skin is able to absorb many substances applied to it, and the same applies to e-liquids. Although propylene glycol and vegetable glycerin rarely cause skin irritation, nicotine can be absorbed through skin contact and inhalation. If you accidentally spill a highly nicotine e-liquid on your hands or get your hands dirty when adding nicotine, wash your hands immediately. Wait a few minutes and observe how you feel, if dizziness or a "nicotine rush" sensation occurs, it usually goes away within a few minutes. At this time, you should stop using e-cigarettes and ensure that there is no residual e-liquid and nicotine in e-cigarettes and workbench surfaces.
