Vaping Basics: It’s All In The Blend

Usually, when I write about a “blend” I’m discussing the mixture of black tobaccos that make up a premium cigar. Today however, we’re talking about the blend of propylene glycol and vegetable glycol used to prepare an e-liquid used for vaping.

Propylene glycol (PG) is an organic compound which is liquid, colorless, nearly flavorless with a slight sweetness. Because PG readily mixes with other liquids it makes a great base for our e-liquid. PG is also used in the preparation of many other daily items including some foods and medicines. PG is generally considered “safe” for human consumption and forms the base for many inhaled medications like asthma inhalers.

Vegetable glycol (VG) or glycerin is a naturally occurring compound derived from plants. Like PG it is also colorless, odorless, and nearly tasteless with a sweet flavor. VG is also used in many products we use daily and is also a common ingredient in medicines. Like PG, VG is generally considered safe for human consumption and is used in many food products.

E-liquids are created by blending PG and VG, in differing ratios, and adding flavorings, sweeteners, and often nicotine. Since both compounds are viscous (thick) liquids, it takes longer for the liquids to evaporate and when heated each produces a large amount of steam (vapor).

By mixing PG and VG in different amounts, manufacturers (and consumers) can control the amount of vapor produced by a particular liquid as well as controlling the amount of “throat hit” the user experiences.

While each manufacturer tweaks their e-liquids for a particular profile, here are some general guidelines that will help you in selecting the best blend for you.  (Ratios list amount of PG first, VG content second)

100% PG – produces a very strong “throat hit” and a clean flavor with very little vapor production

80%/20% – mixed using 80% PG and 20% VG this blend still produces a fairly strong “throat hit” but yields better vapor production from the VG

70%/30% – a very common blend which produces some “throat hit” and good vapor production

50%/50% – evenly mixed, PG and VG produce ample vapor with a noticeable “throat hit”

40%/60% – delivers substantial vapor with minimal “throat hit” and more sweetness

30%/70% – very good vapor production with minimal “throat hit” and more sweetness

20%/80% – very thick vapor production with very small amount of “throat hit” and even more sweetness

100% VG – amazing vapor production with no noticeable “throat hit” and a predominate sweetness

To sum it all up, the higher the concentration of PG, the more “cigarette” like the vaping experience will be with noticible “throat hit.” Increase the amount of VG and the vapor production goes up, “throat hit” goes down, and sweetness increases.

We hope this helps you better understand the complexities of creating an e-liquid and makes your next shopping experience at SmokesOnMain easier and more enjoyable.

Vape On!
