Essential Oils are distilled and used for a wide variety of purposes. Aromatherapy, the perfume industry, household deodorizers and cleaning agents, the cosmetics industry, and the culinary industry, are all environments where the use of essential oils are present. Each of these industries uses a different standard of essential oil in the products they manufacture.
The quality and purity standards associated with aromatherapy are usually the highest of all the industries currently using essential oils in their products. This is an important factor because the level of quality and purity for an essential oil, has an enormous impact on the therapeutic value, color, aroma, and even the flavor when applicable in the food and beverage industry.
The price for an essential oil is also determined by the level of quality and purity produced during the distillation process of the oil. This is an important aspect to be aware of; essential oils that are identified as having specific characteristics considered to be superior to other essential oils, the price of the oil will escalate significantly. When this occurs, it may cause certain distillation companies and supply chains to consider altering the end product, either through dilution or another form of adulteration.
The characteristics and aspects associated with the quality and purity of each and every essential oil can be subjected to quantifiable testing through laboratory procedures. It is highly recommended that this testing be done by an independent third party that has no financial ties to the distiller, and/or supplier, as this will provide an unbiased and informed result. That being said, certain characteristics of an essential oil’s quality are subjective to the individual conducting the testing, such as the olfactory presence (smell) when used in the perfume and household cleaner industries.
