Some of us think more than others what is in e-liquids? And knowledge is power, so I’ll share with you what I know.
The Internet is full of studies by well known Universities and laboratories. So with a little look-around you will find plenty.
Some of the studies can be found from ECITA’s website.
Main components in e-liquids :
Nicotine – All the reputable vendors/e-liquid manufacturers have certificates on the ingredients they use.
Most often the used nicotine is 99.999% pure pharma grade nicotine.
PG (Propylene glycol) & VG (Vegetable Glycerine) – These are the two main vaporizing parts in e liquid
flavours – These are most often the same stuff used in food and pastry (food grade).
VG aka Vegetable Glycerine aka Glycerol
“In foods and beverages, glycerol serves as a humectant, solvent, and sweetener, and may help preserve foods. It is also used as filler in commercially prepared low-fat foods (e.g., cookies), and as a thickening agent in liqueurs. For human consumption, glycerol is classified by the U.S. FDA among the sugar alcohols as a caloric macronutrient.” ~Wikipedia~
PG aka Propylene glycol)
“Propylene glycol is considered Generally Recognized As Safe by the U.S. Food and Drug Administration, and it is used as a humectant (E1520), solvent, and preservative in food and for tobacco products. It is also used in pharmaceutical and personal care products. Propylene glycol is a solvent in many pharmaceuticals, including oral, injectable and topical formulations, such as for diazepam and lorazepam that are insoluble in water, use propylene glycol as a solvent in their clinical, injectable forms.” ~Wikipedia~
PG is one of the main ingredients in e-liquids. There are known cases for people being allergic to PG and cannot tolerate propylene glycol in 100% PG liquids. So if you experience irritation it is recommended you try more VG balanced e-liquids (Like Pipe Sauce-range).
VPG (or PVG) is a shortened name for 50% PG/ 50% VG liquid mix.
Flavoring and what they are made of. As mentioned earlier – Most often the same stuff is used in food and pastry making (food grade). Good example from UK Vapefest 2012 in Tamworth where there was Cakes served that were made using the basic e-liquid flavorings as ingredients. Just a word of note, some food flavourings are NOT suitable for vaping. Diacetyl is safe to eat, but dangerous to inhale, so if people want to make their own flavours up, recommend doing your background checks first. (Credits to Rob N. for pointing this out)
TH and what effects the Throat Hit? There are a few different factors that have something to do with TH
* Strength of the liquid (nicotine mg) – Higher mg = Higher TH
* Voltage used – With higher volts you usually get more TH at the same
* Ohms – Dual Coil cartos usually punch a bigger TH in itself, and the lower the ohms = less volts you need for great TH
* Liquid vaped – Some flavors do pack a bigger punch itself (like Chili concentrate)
VAPOR and things that effect vapor production
* Ohms – as previously explained ohms do effect (depending on the volts used)
* Voltage – this is directly linked to the ohms in a way ^
* PG/VG ratio – PG = More Flavor, Less Vapor vs. VG = More Vapor, Less Flavor
Even a 10% VG does effect a lot on the vapor production.
Nicotine aka 3-[(2S)-1-methylpyrrolidin-2-yl]pyridine
Most of people vape e-liquids to get their daily nicotine dose.
It’s recommended when purchasing e-liquids the first time to choose few different flavours and different strengths.
“Pack a day” people tend to start with higher mg – around 24mg. And from there eventually drop to lower strength.
There are a few different factors that do help you lower your nicotine dose :
upgrade to VV devices and/or lower ohm devices. In the beginning (and when testing new liquids) an inexperienced vaper can get a nicotine overdose. This should be avoided if possible, so start slowly. Main symptoms are nausea, headaches, sweating, palpitations and general weakness.
Remember to keep yourself hydrated and DO NOT vape too strong liquids or too much in one go. Learn your limits.
When handling and storing e-liquid please be careful. Nicotine is poisonous and is not recommended to be digested. In some cases it can also cause irritation if it is in contact with skin.
Even though e-liquid is stored in child-proof bottles you should still keep the bottles out of reach of children, animals and anyone who is not actively using the e-liquids. You should also make sure the cap is on properly and sealed before storing. You can also opt for NoNic products if you wish.
We at eCigWizard also conduct our own quality tests on e-liquid batches that arrive and is made (in addition to the ones the liquid manufacturer makes) to check the quality of the products.
