Preserving perfume

Fragrance compounds in perfumes will degrade or break down if improperly stored in the presence of:

• Heat
• Light
• Oxygen
• Extraneous organic materials

Proper preservation of perfumes involve keeping them away from sources of heat and storing them where they will not be exposed to light. An opened bottle will keep its aroma intact for up to a year, as long as it is full or nearly so, but as the level goes down, the presence of oxygen in the air that is contained in the bottle will alter the perfume's smell character, eventually distorting them.

Perfumes are best preserved when kept in light-tight aluminium bottles or in their original packaging when not in use, and refrigerated at a relatively low temperatures between 3-7 degrees Celsius. Although it is difficult to completely remove oxygen from the headspace of a stored flask of fragrance, opting for spray dispensers instead of rollers and "open" bottles will minimize oxygen exposure. Sprays also have the advantage of isolating fragrance inside a bottle and preventing it from mixing with dust, skin, and detritus, which will degrade and alter the quality of a perfume
