On Vape Juice Expiry & Preserva tion
• Owing to nicotine, PG (Propylene Glycol), and VG (Vegetable Glycerin) components, an e-liquid has a lifespan of 1 to 2 years. As time passes, nicotine oxidation and flavor degradation occur. E-juices that are old tend to have less nicotine with a lighter flavor.
• As for the e-liquid expiration rules and regulations (the extent of the expiry date, display, and advertising), legal mandates for distributors or e-liquid manufacturers are unspecified in the Tobacco and Related Products Regulation (TRPR). But e-liquid standards (non-legally binding in nature) do address the shelf-life of e-juice.
• The onus of regularly conducting product stability studies must be on manufacturers to keep the shelf-life of their products in check. While e-liquids are referred to as “shelf-stable,” after producing the e-liquid, their general shelf-life is two years. But storing the e-cigarette liquid the right way can extend its shelf-life.
