What You’ll Need
- Original dark glass bottle with airtight cap
- Amber or cobalt blue glass bottles (if transferring)
- A cool, dark storage location
- Labels and a marker
Step 1: Use Dark Glass Bottles
Always keep lavender essential oil in dark glass bottles, such as amber or cobalt blue. These colored bottles block harmful UV light, which accelerates oxidation and degrades the oil’s compounds. Clear glass offers no protection from light exposure.
Step 2: Ensure Airtight Sealing
Keep the bottle tightly capped when not in use. Exposure to air causes oxidation, reducing the oil’s potency and changing its aroma. A secure cap prevents oxygen from entering the bottle and volatile compounds from escaping.
Step 3: Store in a Cool Location
Store lavender essential oil at a consistent cool temperature, ideally between 50-70°F (10-21°C). High temperatures can alter the oil’s chemical structure and diminish its therapeutic benefits. Avoid storing near heat sources like stoves or sunny windows.
Step 4: Keep Away from Direct Light
Place essential oil bottles in a dark cupboard, drawer, or storage box. Direct sunlight and even indirect bright light can break down the oil’s delicate components. A dark environment helps preserve its integrity for longer periods.
Step 5: Avoid Humidity and Moisture
Store essential oils in a dry environment, away from areas with high humidity like bathrooms. Moisture can promote microbial growth or degrade labels. A dry, stable atmosphere helps maintain the oil’s purity.
Tips and Best Practices
- Keep original labels intact to track expiration dates and oil type.
- Consider refrigerating essential oils for extremely long-term storage, but allow them to return to room temperature before use.
- Purchase essential oils in smaller bottle sizes (5ml or 10ml) if you use them infrequently to minimize air exposure over time.
- Clean bottle necks after each use to prevent oil residue from hardening and making the cap difficult to open.
- Refer to How To Store Essential Oil Set for general essential oil storage guidelines.
Common Mistakes
- Storing in clear glass bottles: This exposes the oil to light, causing rapid degradation.
- Leaving caps loose: Air exposure oxidizes the oil, reducing its effectiveness.
- Storing in direct sunlight or warm places: Heat speeds up chemical changes in the oil.
- Storing near strong odors: Essential oils can absorb other scents, altering their natural aroma.
FAQ
Q: How long does lavender essential oil last when stored properly? A: Properly stored lavender essential oil typically lasts 2-3 years after opening. Unopened, it can last longer, often 3-5 years.
Q: Can I store lavender essential oil in the refrigerator? A: Yes, storing lavender essential oil in the refrigerator can extend its shelf life, especially in warm climates. Ensure the bottle is tightly sealed to prevent moisture absorption.
Q: What happens if lavender essential oil is stored improperly? A: Improper storage causes the oil to oxidize, lose its aroma, and diminish its therapeutic properties. The oil may also become cloudy or develop an off-odor.
