How does temperature effect oils

[paul linus]

Essential oils and carrier oils should be stored at cool or room temperatures to help increase their shelf life. The optimum storage temperature is five degrees centigrade; some aromatherapists keep a separate mini-fridge to store their essential oils, although this is not really necessary unless you live in a very hot climate. A cool cupboard will provide adequate storage facilities. Cool storage is especially important for citrus oils, which tend to degrade faster than other essential oils.
