Have you ever found yourself in the situation where you find a bottle of e liquid and the expiry date has already passed? What may cross your mind is the fact that you may get sick from using the e liquid. Let’s explore this to see if it is true.
Similar to food, the expiration date that is placed on it is only an estimation of the date that the contents of the bottle/jar/tin, etc are not guaranteed to be the same quality compared to when you purchased it. Most e liquids have a shelf life of 1 - 2 years because there are three significant components of e liquid which are: Vegetable Glycerine, Propylene Glycol and Nicotine. All of these ingredients have a shelf life of around 2 years when they are stored in the correct conditions.
If you store your e liquid in direct sunlight or expose it to extreme heat, the three components begin to deteriorate. The other chemicals within the e liquid such as the flavouring have been reported to taste “stale” when expired. Some flavours react differently. Some can last as long as 5 years, while others may only last for two years.
Since the expiration date is only an estimation, it is dependent on you to decide whether your e liquid tastes ripe when you are vaping it.
