User login

There are two types of carrier fluid that holds the nicotine and flavor in your e-liquids. The two types include propylene glycol and vegetable glycerin. The common characteristics of the two types include the following:
• Odorless
• Tasteless
• Food grade type
• Used for medical purposes
However, the two carrier liquids have differences. The differences between the two types are explained below:

Propylene Glycol (PG)
Propylene glycol is recognized by the U.S Food and Drug Administration as a safe organic compound which has the food grade standard. It is a product of propylene oxide which is an organic compound. Propylene glycol is often used for tobacco products, food preservatives, and pharmaceutical products. Yet, today it is also used for e-liquids. nicvape.co.nzoffers some in-depth insights on e-juice.

Vegetable Glycerin (VG)
Vegetable Glycerin is also considered safe by the U.S. Food and Drug Administration. Generally, this type of natural liquid compound is extracted from different types of oils such as palm oil and soy. It is used in cosmetics and other food grade products.

Comparison
Vegetable glycerin provides duller flavor than propylene glycol. When you use the vegetable glycerin you will notice that the coil and inside walls of the delivery device of the e-liquids forms of a faster build up. The reason behind it is the consistency and high density of the vegetable glycerin.

So the manufacturers combine the proportions of vegetable glycerin and propylene glycol. In most cases, you can see the following ratios of propylene glycol to vegetable glycerin - 50/50, 60/40 or 70/30 ratios.The combination of the two substances is perfect in balancing the characteristics of a satisfying e-liquid. The combination balances the vapor density, throat hit, and flavor intensity.
