Essential oils, and citrus oils in particular, quickly lose their scent and properties if stored incorrectly. For BLACKFOREST mandarin oil, the following recommendations apply:
- A dark place. Direct sunlight speeds up oxidation. It is best to keep the bottle in a cupboard, make-up bag or box — away from the window.
- A cool temperature. Store the oil at +5 to +25 °C, in a dry place, out of the reach of children. Storing it next to a radiator or in a bathroom where the temperature fluctuates is not advisable.
- A tightly closed bottle. Close the cap immediately after each use: the volatile substances evaporate quickly and the scent weakens over time.
- Upright position. This reduces contact between the oil and the cap and lowers the risk of leaks.
Citrus essential oils generally have a shorter shelf life than woody or resinous ones; the expiry date of a particular bottle is stated on the packaging. If the scent has become noticeably weaker or has changed, it is better not to use the oil in cosmetic blends.
