SHELF LIFE OF ELIQUID & NICOTINE

Freezer vs. Non-Freezer Storage

The shelf life of liquid nicotine is significantly influenced by storage conditions, with freezer storage offering the longest preservation period compared to non-freezer options like refrigeration or room temperature. Exposure to heat, light, and air are the primary factors that degrade nicotine over time.

FREEZER STORAGE: MAXIMIZING SHELF LIFE:

Storing liquid nicotine in a freezer, ideally at temperatures around -18°C (0°F) or lower, is widely recommended for long-term preservation. Under these conditions, the degradation process, primarily oxidation, is dramatically slowed.

EXTENDED LIFESPAN:

While exact figures vary depending on the purity of the nicotine, its base (propylene glycol - PG or vegetable glycerin - VG), and packaging, freezer storage can extend the shelf life of nicotine to several years, potentially 5 to 10 years or even longer, especially for unopened, high-quality, concentrated nicotine base stored in airtight, dark glass containers. Some user experiences and expert opinions suggest that correctly stored samples have remained viable for a decade.

BEST PRACTICES FOR FREEZING:

Use airtight, dark glass bottles to prevent oxygen and light exposure and to avoid potential leaching from plastic containers over extended periods. For 120mL quantities, consider decanting into smaller, full bottles to minimize air exposure in the opened container each time it's accessed.

PG-based nicotine solutions tend not to freeze solid, while VG-based solutions become very thick and viscous. Allow frozen nicotine to return to room temperature slowly before use.

NON-FREEZER STORAGE / VIABLE OPTIONS:

When a freezer is not an option, storing liquid nicotine in a cool, dark place is the next best approach.

REFRIGERATION (COOL STORAGE):

Storing liquid nicotine in a refrigerator (typically between 0°C to 10°C or 32°F to 50°F) can also significantly extend its shelf life compared to room temperature by slowing down chemical reactions.

LIFESPAN:

While not as long-lasting as freezer storage, refrigeration can help preserve nicotine for 1 to 2 years or potentially longer for unopened products, especially pure nicotine or nicotine salts.

CONSIDERATIONS:

Ensure containers are airtight to prevent moisture absorption, which can be a concern in refrigerated environments.

ROOM TEMPERATURE (COOL, DARK PLACE):

If neither freezing nor refrigeration is feasible, storing liquid nicotine at a stable room temperature (ideally between 18°C to 25°C or 65°F to 72°F) in a dark location, away from direct sunlight and heat sources, is crucial.

LIFESPAN:

For unopened e-liquids containing nicotine, the general shelf life is typically 1 to 2 years from the date of manufacture. Once opened, this timeframe can decrease to roughly 3 to 12 months, depending on the specific formulation and frequency of exposure to air and light. Pure nicotine, if carefully stored, might last longer.

KEY FACTORS AFFECTING SHELF LIFE

• OXYGEN: Oxidation is a primary cause of nicotine degradation. Always keep containers tightly sealed.
• LIGHT: UV light accelerates nicotine breakdown. Store in dark or opaque containers.
• HEAT: Higher temperatures speed up chemical reactions, leading to faster degradation.
• CONTAINER MATERIAL: Dark glass is preferred for long-term storage over plastic.
• PURITY AND CONCENTRATION: Highly concentrated or pure nicotine may have different long-term storage characteristics than diluted e-liquids.
• INGREDIENTS (for e-liquids): The other components in e-liquids, such as flavorings, PG, and VG, also have their own shelf lives, which can impact the overall product. VG generally has a shelf life of 2-3 years, while PG can last much longer.

In summary, storing liquid nicotine in an airtight dark glass container in a freezer for the longest possible shelf life is the optimal method. Refrigeration offers a good middle ground, while room temperature storage in a cool, dark place is suitable for shorter-term use, with a general expectation of 1-2 years for unopened products.
