Over the past couple of weeks, I have written about both middle note essential oils and base note essential oils for aromatherapy; today, we are taking a look at top note essential oils.  Top note essential oils are the lightest type of essential oils and are the first to evaporate in fragrance terms.  The following text is again amended from the original article which was published at Suite 101.

A lot of top note essential oils do not have a long shelf life because they evaporate quickly. They are relatively easily to extract from plants and consequently are economical in price. Many of the citrus essential oils are top note oils.

The Extraction of Top Note Essential Oils

There are two main traditional methods of extracting top note essential oils for therapeutic aromatherapy use. Firstly, essential oil molecules evaporate during a distillation process of heat, water and steam. The most volatile and smallest molecules are called top notes. Secondly, many citrus essential oils are obtained from plants through a process called expression. Expression extracts essential oils directly from the rind or peel of the fruit.
