What causes discoloration in vape oil?

Electronic cigarette oil discoloration is a phenomenon often encountered by e-cigarette users, it will gradually become light white or light brown from the beginning of colorless and transparent, making people feel very confused.

So, what is the cause of electronic cigarette oil discoloration?
First of all, the discoloration of electronic cigarette oil is a normal phenomenon, which is mainly due to the oxidation of propylene glycol in the electronic cigarette oil and the oxygen in the air. When the electronic cigarette oil is exposed to air, oxygen will oxidize the ingredients in it, making the color of the oil change. This reaction is normal and does not produce harmful substances, so there is no need to worry about the electronic cigarette oil discoloration will be harmful to the body.

On the other hand, there are three types of changes that can occur after the electronic cigarette oil is opened, including discoloration, flavor change, and metamorphosis. Among them, discoloration is one of the most common cases. Usually, it is normal for electronic cigarette oil to turn from colorless to light white or light brown, and the discoloration will tend to fluctuate after 1 to 3 months of storage. If the color of the electronic cigarette oil continues to change substantially after six months of storage, it is possible that it has metamorphosed.

At the end of the day, storing vape oil for too long can lead to a change in flavor. Just like wine, a slight change in flavor is a normal reaction and does not affect the use of the e-cigarette oil. In the end, the metamorphosis of e-cigarette oil is less common, which is usually caused by the unreasonable formula of e-cigarette oil and the overly complicated configuration ratio. In such cases, the most accurate way to determine whether the e-cigarette oil can continue to be used is to smoke it directly and see if there is a significant change in flavor.

Overall, electronic cigarette oil discoloration is a normal phenomenon and will not cause harm to the body. However, in order to ensure the quality and taste of electronic cigarette oil, consumers should pay attention to the storage conditions and avoid exposure to sunlight or high temperature environment to avoid deterioration of electronic cigarette oil. If the electronic cigarette oil is found to have obvious signs of deterioration, it is best to replace it with a new electronic cigarette oil in a timely manner.

How long is the shelf life of electronic cigarette oil?
The composition of the electronic cigarette oil is relatively stable, so it can be stored for a long time, although the shelf life is usually marked as one to two years, but in fact more than three years can continue to use. However, if you have doubts about storing electronic cigarette oil for a long time, it is not recommended to use it.

There are several factors that need to be considered to determine whether electronic cigarette oil is spoiled, such as the quality of propylene glycol (PG), vegetable glycerin (VG), nicotine and flavoring agents, the ratio of them mixed together, and the storage conditions of the electronic cigarette oil. All of these factors can affect the shelf life of a vape oil.

How long is it better to smoke out a cartridge?
Different atomizers have different cartridge volumes, the common ones are 1.8ml, 2ml, 3ml, 3.5ml, 3ml, 3.5ml. therefore, you need to consider your smoking frequency and habits when choosing a cartridge volume. Usually it is recommended to smoke out the cartridge within 3 days, too much time can easily lead to the contamination of the electronic cigarette oil by the atomization core carbon, with the same time there may also be oil leakage. If you feel that a bottle of e-cigarette oil is too large to finish, you can choose a smaller capacity of the cartridge.
It should be noted that although the electronic cigarette oil can still be used after discoloration, it is not recommended to store the electronic cigarette oil for too long.
