perfume articles containing one isomer of an octahydrotetramethyl acetonaphthone, John B. Hall, Rumson; James Milton Sanders, Eatontown , Publication Date: 30 December 1975 to emulate the opulent golden warmth of the fossil. The scent of amber was originally derived from emulating the scent of ambergris and/or the plant resin labdanum, but since sperm whales are endangered, the scent of amber is now largely derived from labdanum. The term "amber" is loosely used to describe a scent that is warm, musky, rich and honey-like, and also somewhat earthy. Benzoin is usually part of the recipe. Vanilla and cloves are sometimes used to enhance the aroma. "Amber" perfumes may be created using combinations of labdanum, benzoin resin, copal (a type of tree resin used in incense manufacture), vanilla, Dammara resin and/or synthetic materials. In Arab Muslim tradition, popular scents include amber, jasmine, musk and oud (agarwood). Imitation substances Young resins used as imitations: Kauri resin from Agathis australis trees in New Zealand. The copals (subfossil resins). The African and American (Colombia) copals from Leguminosae trees family (genus Hymenaea). Amber of the Dominican or Mexican type (Class I of fossil resins). Copals from Manilia (Indonesia) and from New Zealand from trees of the genus Agathis'' (family Araucariaceae) Other fossil resins: burmite in Burma, rumenite in Romania, and simetite in Sicily. Other natural resins — cellulose or chitin, etc. Plastics used as imitations: Stained glass (inorganic material) and other ceramic materials Celluloid Cellulose nitrate (first obtained in 1833) — a product of treatment of cellulose with nitration mixture. Acetylcellulose (not in the use at present) Galalith or "artificial horn" (condensation product of casein and formaldehyde), other trade names: Alladinite, Erinoid, Lactoid. Casein — a conjugated protein forming from the casein precursor – caseinogen. Resolane (phenolic resins or phenoplasts, not in the use at present) Bakelite resine (resol, phenolic resins), product from Africa are known under the misleading name "African amber". Carbamide resins — melamine, formaldehyde and urea-formaldehyde resins. Epoxy novolac (phenolic resins), unofficial name "antique amber", not in the use at present Polyesters (Polish amber imitation) with styrene. For example, unsaturated polyester resins (polymals) are produced by Chemical Industrial Works "Organika" in Sarzyna, Poland; estomal are produced by Laminopol firm. Polybern or sticked amber is artificial resins the curled chips are obtained, whereas in the case of amber – small scraps. "African amber" (polyester, synacryl is then probably other name of the same resine)
