Our subject is the future supplies of natural raw materials for the essential oil industry. We might divide these raw materials roughly into three groups: 1) those that serve as raw materials in the production of isolates, competing head-on with synthetics and including citronella, lemongrass, menthol, and clove leaf; 2) those that can be replaced by synthetic oils, such as anis, rose, fir needle, geranium, citrus oils, sandalwood mint oils, and floral extractives; 3) those that are not threatened by replacements–at least for the present– including cedarwood, eucalyptus, guaiaewood, lavandin, ocotea, petitgrain, patchouli, vetivert, and ylang.
