Notes and Carrier Oils in Aromatherapy

"Notes" of essential oils
There are three categories or classifications of essential oils: top note, middle note and base note. These terms describe the rate at which they evaporate, or how long the fragrance will last.

Top note fragrances are the most stimulating and strongly scented but the scent only lasts for 3 to 24 hours. Some top note essential oils are basil, bergamot, clary sage, coriander, eucalyptus, lemongrass, neroli, peppermint, sage and thyme.

Middle note oil fragrances last about two to three days and they affect the metabolic and body functions. The scent is less potent than top note fragrances. Some middle note oils are balm, chamomile, fennel, geranium, hyssop, juniper, lavender and rosemary.

Base note essential oils are the slowest to evaporate and can last up to a week. The usually have a sweet, soothing scent and a relaxing effect on the body. Some examples of base note oils are cedarwood, clove, frankincense, ginger, jasmine, rose and sandalwood.

Carrier oils

Some of the most commonly used carrier oils are:
