1. Use Dark Glass Bottles

Fragrance oils are sensitive to light, especially UV rays, which can cause the oils to break down over time. To protect your oils:

• Store them in amber or cobalt blue glass bottles.

• Avoid clear plastic containers, as they allow light to penetrate and may interact with the oil.

2. Keep Away From Heat Sources

Heat accelerates the degradation process of fragrance oils. Avoid storing oils near:

• Windows exposed to sunlight

• Radiators, ovens, or stoves

• Areas prone to temperature fluctuations (like bathrooms)

Best practice: Store at cool room temperature (around 15–20°C / 59–68°F).

3. Seal Tightly After Each Use

Oxygen exposure can cause fragrance oils to oxidize and lose their aroma. Make sure to:

• Close the bottle immediately after use

• Use bottles with airtight caps or droppers

This helps prevent evaporation and contamination.

4. Label Your Oils Clearly

Over time, even seasoned users can forget which oil is which. Always:

• Label bottles with the name, purchase date, and batch number (if applicable)

• Organize by type or use (e.g., floral, citrus, earthy)

Proper labeling ensures you track shelf life and usage more efficiently.

5. Avoid Humid Environments

Humidity can affect the consistency and potency of fragrance oils. For optimal results:

• Store in dry environments

• Avoid areas like the bathroom or kitchen where moisture levels fluctuate

6. Use a Storage Box or Cabinet

If you have a collection of oils, consider investing in a wooden storage box or a cool, dark cabinet. These protect your oils from light, dust, and accidental spills.

7. Don’t Refrigerate Unless Specified

While some oils can benefit from refrigeration, most fragrance oils do not need it. If refrigeration is necessary:

• Store in an airtight container

• Allow the oil to reach room temperature before opening, to prevent condensation
