Aromatherapy Blends Part 1

Blending aromatherapy oils in to a well balanced mix is a workmanship that is a combination of an art as well as aesthetic ness. Aromatherapy blends that complement workout routines in our daily lives are among the fastest growing uses of aromatherapy today.

An essential oil blend is created for aesthetic and/or therapeutic benefits. No special skill is required to produce a successful blend but a spirit of creativity and a thorough knowledge of oils will help, along with a clear understanding of the intended use of the blend. A sensible aromatherapy blend employs all-natural, pure essential oils and delivers a clear benefit. The oils combined in it should be synergistic and harmonious enough to support and enhance oil's effect.

Before starting your blending work, it's very important to understand essential oils in general, as well as the specific parameters and aroma profiles of the oils you want to work with.
Essential oils are essentially very volatile. When you uncap a bottle of essential oil and expose it to the air, its aroma profile immediately begins to spread, develop and change. It undergoes certain defined morphological changes during its life span.

The three main stages of these changes are known as the top note stage, middle stage, and dry out stage. These stages of volatility coincide with three characteristics of the aroma profile known as top notes, middle notes and base notes. The top note stage appears first and corresponds with the most volatile, productive and unstable aroma compounds of the oil.

The aromas of these compounds are very subtle, smooth and fleeting, sometimes lasting just for a few seconds before dissipating. As the top notes evaporate very gradually, the oil enters its middle stage, in which the aroma body is most developed and balanced. A portion of the top notes remain, the middle notes are most apparent and sensible while the base notes are beginning to develop slowly.

As the middle stage progresses slowly, the base notes become visible and more noticeable, because they consist of compounds that are slow to volatilization. When the base notes finally evaporate, a faint but light dry out note lingers. The aroma profile of the dry out stage is thin, sometimes pungent, and suggests the presence of the oil. The dry out component can be thought of as the matrix or the soul of the oil.

Based on their individual aroma profiles, oils can be categorized into top notes, middle notes and bottom notes. A very delicate, highly volatile oil like bergamot is considered top note oil. Well balanced oil like clary sage would be known as middle note oil. Deep, rich, very tenacious oil like patchouli is considered base note oil.
