The question has already been dealt with many times, if you follow the news of the vape, but it is not necessarily a given for everyone, which is why we have decided to talk about the expiration dates of e- liquid. So, should we throw away all our nicotine products that are past the deadline? We will get to the heart of the matter with this dossier.
THE DEADLINE ? AN OBLIGATION FOR ANY PRODUCT INTENDED FOR CONSUMPTION!
First of all, it should be noted that, as with all products intended for consumption, legislation requires manufacturers to indicate an expiry date on the bottles. Two types of marking are possible at the choice of the manufacturer: DLC: Use-by date which is expressed on the packaging in the form “to be consumed until (DLC)”: it sets the date from which the liquid is no longer consumable.
or the Best before: Best before date also called DDM (date of minimum durability) which is expressed on the packaging in the form " to consume preferably before (DLUO / DDM) »: It sets the date from which the liquid loses its properties while remaining consumable. And between these two markings, there is a very important difference for us vapers! So for e-liquids, DLC or DLUO (DDM) ?
FOR AN E-LIQUID, WE WILL TALK ABOUT DLUO / DDM (OPTIMAL USE DEADLINE).
This should reassure those who did not know and panic those who threw away their bottles of e-liquid thinking they were expired. For an e-liquid we will therefore not speak of DLC, we will rather approach the DLUO / DDM, that is to say that the liquid does not become harmful after the date indicated but quite simply that it risks losing quality. . Clearly, by consuming it after the expiry date, there are certain risks of degradation of the components present in the e-liquid. This is why you will generally find messages of the type: " To consume preferably before »Or in English« ." page (in French).
WHICH COMPONENTS ARE AFFECTED BY DEGRADATION FOLLOWING A DATE EXCEEDING.
You must already know, and prefer to say it again, that exceeding the indicated date will not make the product " harmful »Or unfit for consumption. The date written on the bottle is a date before which it is better to vape the liquid to have its true flavor, because as much to rest an e-liquid is a good thing, as letting it age too long will not bring it maturity. (as with wine). What you should know is that the propylene glycol and vegetal glycerine are not likely to decompose over time, so they are not part of the components involved. The aromas, however, they are, and these can be altered and lose their quality over time, temperature variations, and light. Nicotine also will tend to lose its effectiveness over time, but it will not be more or less harmful. You should therefore know that if your e-liquid exceeds the DLUO / DDM, there is a good chance that it will lose in flavor and also in efficiency in terms of weaning.
THINK TO THE MAXIMUM OF PROTECTING YOUR E-LIQUIDS TO KEEP OPTIMAL QUALITY!
And yes ! It is not only the DLUO / DDM that relies on an e-liquid and know that it can end up with a tasteless taste quite quickly if you do not follow certain precautions. Whatever happens, know that an e-liquid well stored in a cool, dry, constant temperature and protected from light, can last much more than one or two years without too much worry. For that, you will have to find the ideal place, the whole being to avoid that it is attacked by light, heat or humidity.
As a general rule, your e-liquid will have a BBD / DDM varying from one to two years. By protecting it well from light, heat and humidity, you will be able to keep it much longer. However, the best thing to do is to consume your e-liquid after the period of " steep »Performed in order to have the best vaping experience possible.
