The irones are ionone homologues that have an additional methyl group adjacent to the twin methyl groups in the cyclohexane ring. The number of possible irone isomers is larger than that of the ionones due to the additional methyl group on the ring. Some of these irone isomers occur in essential oils from the roots of Orris species (see Orris Root Oil). 

Raw materials derived from intensive agricultural cultivation are usually relatively inexpensive. However, the prices of some natural materials may exceed 1000 per kilogram because cultivation and harvesting of these plants are tedious and product yields are very low. Examples of extremely valuable ingredients of fragrance and flavor creations include rose oil, jasmine absolute, tuberose absolute, orris root oil, ambrette seed oil, angelica root oil, and orange flower oil [220]. 

Orris root oil is obtained by steam distillation of the rhizomes of the sweet iris. Iris pallida Lam. (Iridaceae) cultivated in the Italian province of Tuscany or Iris germanica L. cultivated in Morocco. Prior to distillation the rhizomes are stored for several years and are then ground. The steam distillate is a light yellow to brown-yellow solid mass with a violet-like odor. The solid liquefies to a yellow to yellow-brown liquid at 38-50 °C. 

Fresh orris roots do not contain any irones. These compounds are formed by an oxidative degradation process from higher molecular precursors, the so-called iridales, only when the dried orris roots are stored for a longer period. To avoid such a time-consuming procedure, microbiological processes for the oxidative degradation have been developed [677].

Vitivert, or Kus-hus.—The fleshy part of a specter of dry grass from India, It has an aromatic odor, and is used in the same manner as orris root. The tincture or extract of vitivert is made by digesting one pound of the dried root in a quart of alcohol for two weeks, and filtering. This tincture was formerly much used In bouquet combinations, and was an important ingredient in the once celebrated preparations of that kind called mousselaine des Indes, bouquet du rot, et cetera. By distillation, it yields about one per cent, of volatile oil called otto of vitivert, and resembling, according to Piesse, the otto of santal.

Features The white Florentine root, which is preferred to other varieties, is irregular in shape and shows marks where the rootlets branched before preparation for export. Verona Orris root tapers more gradually than that from Florence, and appears more compressed. The Moroccan root is noticeable for the dirty white cortex which remains on the root. Orris gives off a violet-like scent. 

Large quantities of the finely pulverised root are used in the preparation of toilet and dusting powders, dentifrices and cachous, for which purposes the acceptable fragrancy and other appropriate qualities make Orris root eminently suitable. Toilet recipes are given in another section of this book. 

While perfumes may be simple or complex, they all consist of three principle ingredients the main scent, secondary or blender scents, and a fixative. The main scent is usually potent, and is balanced by the secondary scents added to it. The fixative is a compound that holds the whole thing together. Some fixatives work best for certain scents. The example, the best fixative for lavender scent is orris root. 

Orris Root Oil occurs as a light yellow to brown-yellow mass at room temperature and melts to form a yellow to yellow-brown liquid. It is the volatile oil obtained by steam distillation from the peeled, dried, and aged rhizomes of Iris pallida Lam. (Fam. Iridaceae). It is soluble in most fixed oils, in mineral oil, and in propylene glycol. It is insoluble in glycerin. 

Gather these materials Powdered calcium carbonate (CaC03) powdered orris root sodium bicarbonate (NaHC03) essence of peppermint an empty toothpaste tube a small bowl a teaspoon a pair of heavy-duty scissors and an eye dropper. 

Follow this procedure Straighten the toothpaste tube. With the scissors, cut off the flat bottom end of it. Rinse the tube out very carefully, including the cap. Replace the cap but pull the other end apart to make a wider opening. Set the tube aside to dry. In the small bowl, mix 2 teaspoonfuls of powdered calcium carbonate and 2 teaspoonfuls of powdered orris root. Add teaspoonful of sodium bicarbonate and 3 drops of essence of peppermint. Add water to this mixture, a drop at a time, stirring it constantly until a paste forms. Put the paste into the empty tube by the teaspoonful. Before trying to squeeze the toothpaste from the tube, close the open end by folding it up several times. 

Results Neither calcium carbonate nor orris root mixed easily with water, but the peppermint and the sodium bicarbonate helped give the paste the right consistency. 

Orpiment. Obsolete name for arsenic trisulfide, orris root oil. 

The bark is used as incense—aromatic. The scent is similar to the Indian Orris Root. It is the Cedar of Lebanon, a symbol of power and longevity.
