Comedogenic Oils

Comedogenic Oils. An essential olive oil is a concentrated hydrophobic liquid comprising volatile aroma chemical substances from vegetation. Essential oils are also called volatile oils, ethereal oils, aetherolea, or simply as the oil of the flower from which these were extracted, such as engine oil of clove. An olive oil is "essential" in the sense that it contains the "essence of" the plant's fragrance--the quality perfume of the place from which it comes from. The term essential used here does not mean indispensable much like the terms essential amino acid or essential oily acid which can be so called being that they are nutritionally required by a given living organism.

Essential oils are usually extracted by distillation, often by using heavy steam. Other procedures include appearance, solvent extraction, definite oil removal, resin tapping, and chilly pressing. They are being used in perfumes, cosmetics, soaps and other products, for flavoring drink and food, and for adding scents to incense and household cleaning products.

Essential oils have been used medicinally throughout history. The earliest noted reference to the techniques and methods used to create essential natural oils is thought to be that of Ibn al-Baitar (1188-1248), an Al-Andalusian (Muslim-controlled Spain) doctor, pharmacist and chemist.

Rather than refer to essential oils themselves, modern works typically discuss specific chemical substances of which the essential oils are comprised. For instance: methyl salicylate alternatively than "oil of wintergreen".

Involvement in essential natural oils has revived in recent decades with the level of popularity of aromatherapy, a branch of alternative treatments that uses essential oils and other aromatic substances. Oils are volatilized, diluted in a carrier oil and used in massage, diffused in the air by way of a nebulizer, heated on the candle flame, or burnt as incense.

Medical applications proposed by those who sell medicinal oils range between skin area treatments to remedies for cancer and often are based exclusively on historical accounts of use of essential natural oils for these purposes. Cases for the effectiveness of medical treatments, and treatment of malignancies in particular, are now subject to regulation generally in most countries.

Most popular essential natural oils such as lavender, peppermint, tea tree olive oil, patchouli, and eucalyptus are distilled. Fresh plant material, comprising the blooms, leaves, wood, bark, roots, seed products, or peel, is placed into an alembic (distillation apparatus) over normal water. As this is warmed, the steam moves through the vegetable materials, vaporizing the volatile chemical substances. The vapors circulation through a coil, where they condense back again to water, which is then accumulated in the obtaining vessel.

Most oils are distilled within a process. One exemption is ylang-ylang (Cananga odorata) which is purifed via a fractional distillation.

The recondensed water is referred to as a hydrosol, hydrolat, organic distillate, or herb water essence, which may be sold as another fragrant product. Popular hydrosols include rose water, lavender drinking water, lemon balm, clary sage, and orange blossom normal water. The use of natural distillates in makeup is increasing. Some flower hydrosols have unpleasant smells and are therefore not sold.
