1. Control Light Exposure
Ultraviolet light breaks down aromatic molecules, especially limonene, linalool, and other unsaturated compounds common in citrus and floral notes (Berkowitz et al., 2015). Store bottles in their boxes, drawers, or opaque cabinets to prevent photodegradation and colour change.
2. Maintain Stable Temperature
Fluctuating heat accelerates oxidation and lowers alcohol content. Perfume labs conduct stability tests between 15–20 °C; replicating these conditions at home extends shelf life (Bajaj & Gupta, 2012). Avoid storing fragrance in bathrooms or near heaters where daily swings can exceed 10 °C.
3. Limit Air and Humidity
Oxygen triggers the formation of aldehydes and acids that produce off-notes. Always recap bottles immediately and consider decanting large bottles into smaller atomisers as levels drop. Keep humidity below 60% to prevent label damage and hydrolysis of ester-rich compositions (Herman & Herman, 2015).
4. Monitor Shelf Life
Most alcohol-based fragrances stay stable for three to five years when stored correctly, though top notes may soften over time. If a scent turns noticeably sour or changes colour dramatically, it may be oxidised. Oil-based attars can last longer but should still be kept cool and dark (Sell, 2014).
5. Travel and Seasonal Tips
Temperature spikes in cars or luggage compartments can ruin a bottle in hours. When travelling, wrap bottles in soft fabric, use travel atomisers, and keep fragrance in carry-on baggage to avoid freezing or overheating. In summer, store daily-use bottles in cooler rooms and minimise window exposure.
