E-liquid is the liquid inside a vape pen that produces the vapor when heated, giving it its flavor and nicotine (if you choose).
Propylene glycol (PG) and vegetable glycerin (VG) are the two primary ingredients found in e-liquids.
When heated PG or VG-based eliquids, thermal decomposition can occur and produce reactive aldehydes such as formaldehyde and acetaldehyde. These aldehydes have the potential to cause tissue damage. To know more, check https://www.ecigelm.com/product-category/freebase/.
- Vegetable Glycerin
When creating e-liquid recipes, vegetable glycerin is an essential ingredient. This base fluid can be found in many recipes, along with propylene glycol, for maximum flavor and convenience.
Vegetable glycerin is a syrupy substance made by heating fats high in triglycerides, such as coconut oil or palm oil, to produce an aromatic sweetness.
It’s an effective moisturizer for your skin, and it helps reduce irritation too. Studies suggest it could even have positive effects on overall health and well-being.
- Propylene Glycol
Propylene glycol is a widely-used ingredient in foods and cosmetics. It acts as a humectant, solvent, and preservative.
Due to its numerous beneficial properties, it has become widely used in a variety of products. Unfortunately, its association with antifreeze – an extremely hazardous chemical – has caused some negative perceptions.
- Ethylene Glycol
Ethylene glycol (C2H6O2) is a dihydroxy alcohol often found in antifreeze and water mixtures to transfer heat. It’s also present in industrial coolants and hydraulic brake fluids.
Ethylene glycol is a respiratory irritant and has been classified as a Priority Substance List (PSL) by the Government of Canada for assessment. It mainly escapes into the environment from aircraft de-icing/anti-icing operations as well as manufacturing and processing facilities.
E-liquids are commonly flavored to replicate the taste of various food items. Common flavors like cherry, cinnamon, vanilla, and menthol can be found in many vape juices.
Recent research indicates that certain compounds found in some vape juices can be toxic to human lungs and cause short-term irritation and inflammation. This is likely due to how flavorings react with propylene glycol, an ingredient common to E-liquids, creating entirely new chemicals.
Nicotine is the most prevalent ingredient found in e-liquids. This highly addictive chemical from tobacco plants stimulates the central nervous system, leading to an increase in blood pressure, breathing rate, and heart rate.
E-liquid manufacturers typically offer their products with varying nicotine concentrations, from none to 36 milligrams per milliliter. Furthermore, many newer generations of e-cigarettes use nicotine salts which enable higher levels and efficient delivery of nicotine without irritation.
