What are Absolutes?
Absolutes are highly concentrated aromatic liquids extracted from plants. They are extracted in a complex manner. Absolute distillation requires the use of chemical solvents that are later removed during the final stages of production, thus culminating in a more concentrated essence.
There are reasons for producing absolutes. Many times steam distillation of a plant by steam does not extract as much natural oil from the plant, or in some cases, breaks down the precious natural oil in delicate flowers. The solvent extraction methods are often used in these cases.
As a rule, absolutes are more concentrated than a similar essential oil. Being more concentrated, an absolute goes much further then the essential oil counterpart.
What are Carrier Oils?
Carrier oils are used to dilute essential oils and absolutes before applying to the skin. The carrier oil serves two purposes:
1. To carry the essential oil onto the skin
2. To dilute the potent oil before use.
“MerevilleTrust” at Auroville offers many different carrier oils that feature different properties and the choice of carrier oil can depend on the therapeutic benefit being sought.
The carrier oils are mainly cold-pressed vegetable and fruit oils derived from the fatty portions of the plant. Unlike essential oils that evaporate and have a concentrated aroma, carrier oils do not evaporate or impart their aroma as strongly as essential oils.
What are Resins?
Have you ever come upon a pine tree and noticed a sticky substance on the trunk? This is a resin. During the production of resin, trees will be cut in many spots to encourage the tree to produce its resin. Natural resins are extremely thick and sticky. Most liquid resins are extracted by solvent or alcohol extraction.
Storing Your Essential Oils
Although essential oils do not become rancid, some oils deteriorate with age and may lose their therapeutic benefit over time. Oils such as the citrus oils will oxidize and begin to lose their aroma and therapeutic properties. Some oils such as patchouli and sandalwood can improve with age becoming more rounded and mellow.
To avoid deterioration and protect your oils properties, keep them in amber or cobalt blue bottles. Dark glass such as amber or cobalt helps to keep out sunlight, which can hasten deterioration. Do not keep your oils in clear glass bottles. Beware of oils in plastic as many can dissolve the plastic. Essential oils should also be stored in a cool, dark place.
