How should I store this oil to maintain its quality?

Grapefruit essential oil contains volatile aromatic compounds, such as limonene, which can degrade when exposed to environmental factors. To maintain its fresh, uplifting scent and efficacy:

• Avoid Light: Store the bottle in a dark cupboard or drawer. Direct sunlight accelerates oxidation, which can alter the scent and reduce quality.
• Control Temperature: Keep the product in a cool place. Excessive heat can cause the oil to evaporate or change chemically.
• Seal Tightly: Always replace the cap immediately after use. Essential oils are volatile and can evaporate quickly if left open, leading to a loss of potency.

When stored correctly, the oil will retain its characteristic fresh citrus aroma for a longer period. If the scent becomes weak, sour, or significantly different from when you first opened it, the oil may have oxidized and should be discarded.
