Amber and Aldehydic
The Families · 6 min
Two more family words that mislead beginners, for opposite reasons. One names a thing that does not exist; the other names a chemical class that most people have smelled thousands of times without knowing it.
Amber, the family formerly called oriental, has nothing to do with fossilised tree resin, which is odourless in perfumery terms. It is the accord discussed earlier — labdanum, vanillin, benzoin — expanded into a whole category: warm, sweet, resinous, spicy, with a golden and slightly powdery quality. Ambers run from soft and skin-like to enormous, dense and spice-loaded. The family covers most of what people mean by sensual or heavy perfume, and it dominated the 1980s.
Be careful of one collision: ambergris, amber accord, and Ambroxan are three different things sharing four letters. Ambergris is a marine animal material, salty and mineral, not sweet at all. The amber accord is the sweet resinous construction. Ambroxan is a synthetic that captures part of the ambergris character and is used everywhere in modern perfumery. Ambers are not usually ambergris-y and ambergris is not usually amber-y.
Aldehydic is a family named after a chemical group. Aldehydes are a broad class, many of which smell of nothing remarkable, but in perfumery the word almost always means the fatty aldehydes — C-10, C-11, C-12 — which smell of hot ironing, candle wax, snuffed wicks, clean skin, and a strange metallic sparkle. They are abrasive and slightly unpleasant undiluted. In trace quantity they produce lift: they make everything above them seem to shine, expand and float.
Their moment is 1921, when Ernest Beaux used them at an unprecedented dose in Chanel No 5, producing a floral that did not smell like flowers so much as like an idea of flowers, abstract and luminous. That single decision is arguably the origin of modern perfumery, because it announced that a fragrance need not imitate anything found in a garden.
An aldehydic fragrance is recognisable by a particular soapy-waxy brightness in the opening that seems to hover slightly above the rest of the composition. Once you have identified it you cannot un-identify it, and you will notice it in a great many classic florals — often as the reason they smell expensive rather than merely floral.
