Oils such as the citrus oils will oxidize and begin to lose their aroma and therapeutic properties. Some oils such as patchouli and sandalwood can improve with age becoming more rounded and mellow.
To avoid deterioration and protect your oils properties, keep your oils in amber or cobalt blue bottles. Dark glass such as amber or cobalt helps to keep out sunlight, which can hasten deterioration. Do not keep your oils in clear glass bottles. Beware of sellers selling oils in plastic as many oils can dissolve plastic. Essential oils should also be stored in a cool, dark place.
