When buying e-cigarettes , many people like to buy a lot of flavors of e-liquids that they have never tried. If there is too much e-liquid, it may be left for too long. Although e-liquid is not a food, it is also a product for human consumption and has a shelf life. So, what should I do if the e-liquid is expired? Can I still smoke it?
1. The components of e-cigarette oil are relatively stable molecules and can be stored for a long time. Although the shelf life is usually marked as one to two years, it can actually be used for more than three years. If you have concerns about long-term storage of oil, then don't use it.
2. When determining whether the e-liquid has gone bad, there are many variables to consider. The quality of PG, VG, nicotine and flavorings, the ratio in which they are mixed together, and the storage conditions of the e-liquid will affect the shelf life of your e-liquid.
3. The shelf life of e-liquid is a conservative way of writing. In fact, mature e-liquid formulas have not been found to deteriorate in extreme experiments. Usually, deterioration is caused by poor e-liquid formula and unreasonable ratio. The most accurate way to judge whether it is safe to smoke is to smoke it and see if there is a big change in the taste.
How to determine whether e-cigarettes can still be smoked?
1. Change of taste
The storage of e-liquid will cause an aging reaction, just like wine, so it is normal for the taste to change slightly.
2. Color change
The color may change from colorless to light red, light brown, etc. Generally, the color change will stabilize in 1 to 2 months. If the color of the e-liquid continues to change significantly after being stored for half a year, it may have deteriorated.
3. Deterioration
The shelf life of e-liquid is a conservative way of writing. In fact, mature e-liquid formulas have not been found to deteriorate in extreme experiments. Usually, deterioration is caused by poor e-liquid formulas and unreasonable ratios. The most accurate way to judge whether it is safe to smoke is to smoke it and see if the taste has changed significantly.
Storage: To prevent changes in taste, it is best to store away from light and heat.
It is worth noting that it must be stored in a sealed container. E-liquid contains glycerin, which is a water-absorbing substance. If it is stored in an open container for a long time, the aroma substances will evaporate. In addition, the e-liquid will absorb a lot of moisture in the air, and it will definitely deteriorate if it contains too much water.
