The material could be used directly (as frankincense and myrrh) or extracted in some way. Many of the compounds used in perfumery are hydrophobic and must be extracted with organic solvents. Other materials known as fixatives retard and modify the evaporation of volatile essential oils.There are five types: concretes, absolutes, distilled and fractionally distilled oils, expressed oils and tinctures.Many factors determine which method is used. Among these are cost, quality of essence, and use of the product.The basic ingredients are odorants: 1. concretes - first extraction with hydrocarbon solvent2. absolutes - produced by extracting concrete with alcohol; waxes and glycerides are left behind, alcohol is evaporated, most perfumes are mixtures of absolutes .3. distilled and fractionally distilled oils - involves steam extraction and fractionation. Oils are skimmed off condensed water, is inexpensive and rapid but destroys some fragrances.4. expressing oils - oils are pressed out of tissue - citrus rinds5. tinctures - substances are heated in alcohol, used mainly for animal substances
