The discoloration of the liquid is a normal phenomenon, which is due to the oxidation of the propylene glycol in the liquid and the oxygen in the air. This is a normal reaction in which no harmful substances are produced. So don’t worry, you can keep using it.
There are three kinds of changes after the liquid oil is opened
1. Discoloration. Can show colorless to light white, light brown, etc., ordinary 1 to 2 months, the color will fluctuate. If the color of the liquid oil after storage for half a year continues to change significantly, it can be transformed.
2. Stale. The storage of cigarette oil will have a mellow reaction, just like wine, a little stale is normal.
3. Change. The shelf life of lampblack is a radical formulation. No disintegration was found in the limit test of the real mature formula of fume oil. Usually, the disintegration is caused by a bad formula and an unreasonable ratio of smoke oil. The most accurate way to know if you can smoke it is to smoke it and see if there is a big change in the taste.
How long is the shelf life of the liquid?
1, the components of electronic cigarette oil are relatively stable molecular composition, can be stored for a long time, although the shelf life is usually marked as one to two years, but in fact more than 3 years can continue to use, if you have concerns about long-term storage of cigarette oil, then do not use.
2, in judging whether the deterioration of the liquid, you need to consider a lot of variables, PG, VG, nicotine and flavoring quality, the proportion of them mixed together, and the storage conditions of the liquid will affect the shelf life of your liquid.
How long is it better to smoke the good fume?
Different atomizers, oil tank volume is not the same. The volume of the common atomizer oil tank is: 1.8ml, 2ml, 2.5ml, 3ml, 3.5ml. Depending on the user’s frequency of use, the time consumed is also different.
So according to each person’s different smoking habits, to determine the amount of smoke oil. Generally, the smoke oil is best pumped within 2 days, and the smoke oil is easy to be polluted by the carbon accumulation of the atomizing core for a long time, and it is easy to have oil leakage. Therefore, according to our own situation, if we can not finish smoking in 2 days, we can fill a little less when filling the smoke oil.
Once again, remind everyone that if only the liquid is discolored, it can be used, but it is recommended that you do not leave a bottle of liquid for too long, if you feel that a large amount of smoke can not be finished, you can buy a smaller capacity of liquid.
