The storage of e-liquid requires strict control of temperature and humidity to ensure the stability of components and the quality of taste. The specific requirements are as follows:
Conventional storage temperature
Recommended range: Between 10℃ and 30℃, with the optimal storage temperature being 15℃ to 25℃.
High-temperature risk: When the temperature exceeds 30℃, propylene glycol (PG) and vegetable glycerin (VG) in e-liquid will accelerate oxidation, causing the e-liquid to become thinner, darker in color, and even develop an unpleasant odor.
Low-temperature risk: When the temperature drops below 10℃, the e-liquid may crystallize due to low temperature, affecting the atomization effect.
Extreme temperature taboo
High temperature: Avoid environments with temperatures exceeding 50℃. High temperatures can cause chemical reactions between the flavoring and nicotine in e-liquid, resulting in a deterioration of the taste.
Low temperature: Avoid environments with temperatures below 0℃. Low temperatures may cause the e-liquid to solidify and damage the atomizer.
Recommended humidity range
Optimal humidity: between 10% and 70%, and the best storage humidity is between 40% and 60%.
High humidity risk: When the humidity exceeds 70%, e-liquid may absorb moisture from the air, leading to dilution or contamination, which affects the taste and the amount of smoke.
Low humidity risk: When the humidity is below 10%, e-liquid may evaporate due to drying, resulting in changes in concentration.
Humidity control method
Sealed storage: Use a sealed bottle or self-sealing bag to prevent the e-liquid from coming into contact with air.
Desiccant assistance: Place a desiccant (such as a silica gel bag) in the storage container to absorb excess moisture.
Store away from light
The reason is that ultraviolet rays can accelerate the decomposition of chemical components in e-liquid, leading to changes in taste and efficacy.
Method: Store the e-liquid in a cool and dark place, or use a dark-colored container.
Avoid unpleasant odors
The reason is that e-liquid is prone to absorbing odors, resulting in a poor taste.
Method: Store e-liquid separately from volatile items such as food and perfume.
Short-term high-temperature environment
Method: Put the e-liquid in an insulated bag and add an ice pack to keep the internal temperature below 30℃.
Long-term preservation
Method: Put the e-liquid in the refrigerator's crisper drawer (not the freezer compartment), and seal the package to prevent condensation water from entering.
Taste change: After e-liquid deteriorates, its taste may become milder, more sour or develop an unpleasant odor.
Health risk: Deteriorated e-liquid may produce harmful substances and may irritate the respiratory tract after inhalation.
Equipment damage: Leaking or crystallized e-liquid may damage the atomizer or the main unit.
Summary: The storage of e-liquid must strictly follow the requirements of a temperature ranging from 10℃ to 30℃ and a humidity of 10% to 70%. It is also necessary to pay attention to avoiding light, sealing and preventing odors. High temperature, high humidity or light conditions will accelerate the deterioration of e-liquid, affecting its taste and the lifespan of the equipment.
