The information on an e-liquid bottle answers several different questions: what the liquid contains, its nicotine concentration and how it should be stored. Understanding those details helps you avoid confusing one measurement with another.
What does 70PG/30VG mean?
Jenson describes its High PG range as 70PG/30VG. PG stands for propylene glycol, while VG stands for vegetable glycerine. The ratio describes the liquid’s PG/VG balance—it does not describe its nicotine strength. Jenson’s High PG information.
For example, “70PG” does not mean 70% nicotine. Nicotine concentration is a separate piece of information on the label, usually expressed in milligrams per millilitre, or mg/ml.
Keep the bottle and its label together
Keep your liquid in its original container. Transferring it into another bottle can separate it from its warnings, ingredient information and batch details.
Before putting it away, check that the cap closes securely and the bottle is not leaking. Keep the label readable, including any printed date and storage instructions.
Choose a secure storage place
Jenson’s storage guidance advises keeping e-liquids away from direct sunlight and direct heat, and out of reach of children and pets. A secure cupboard is preferable to a windowsill, car dashboard or accessible bedside table. Jenson’s storage guidance.
What if something seems wrong?
If the bottle is damaged, its contents are uncertain or its label is unreadable, set it aside securely and contact Jenson before using it. Include a photograph and any visible batch information.
Do not rely on colour alone to decide whether a liquid is suitable to use. Follow the specific bottle’s instructions and ask for clarification when something has changed unexpectedly.
