Between 1919 and 1921, perfumer Ernest Beaux created a series of compositions. They were likely modifications of his successful Rallet N°1 (1914), also known as Le Bouquet de Catherine (Rallet, 1913) before the name change. They were presented to the mademoiselle. One was selected in 1921 and became Chanel N°5, and another was released a year later as Chanel N°22. This derivation from Rallet N°1 might explain resemblance between both as fragrances of aldehydic floral family, which combines aldehydic notes, flowers, and woods. But whereas the accent of Chanel N°5 falls on its opulent florals, Chanel N°22 plays up its dry woody notes.
It is certainly a kinsman of Chanel N°5. It is aldehydic. Its metallic, citrusy, waxy notes are bright and scintillating—a counterbalance for the heft of white flowers. But there is also the warmth of sweet ylang ylang in the opening. Its solar and floral note does an excellent job at tempering the metallic chills of the aldehydic top.
The floral depth of ylang ylang that opens Chanel N°22 also bridges well to the heady white flowers. Orange blossom and jasmine absolute at 0.2% lend their peculiar narcotic accent to the composition. Th sensual florals remind me of a classic white strand of pearls that would lend an elegant touch.
Their decadent florals are matched by the dry woods, vetiver, and frankincense. The combined effect is that of incensed woods interspersed with white petals. Its woody note is rounded by a powdery sweet vanillic note. Towards the dry down, it is powdery, and incensed woods and musk form the main impression.
Chanel N°5 may be the classic floral aldehydic perfume, but Chanel N°22 is just as interesting a composition. Aside from the classical shimmering effect the aldehydic top has on its languorous white florals, the woody notes and incense provide a sober contrast. The indulgent florals are kept in check as the dry woods dominate, and this tension gives Chanel N°22 its character. It is a sublime woody variation of the original floral aldehydic composition.
A note on the concentrations: The extrait de parfum is no doubt rich with fatty absolutes from heady jasmine and carnal orange blossoms. But what startles me most in the extrait de parfum are the noble and rich woods of incense that fume out of skin on top of narcotic floral absolutes. It is basically the same as the eau de toilette, but its richness and the way its incense note emerges will make you swoon.
