Definition
Chanel N°5 (1921) refers to the fragrance composed by Ernest Beaux (1881–1961, French perfumer of Russian origin) for Gabrielle Chanel, launched in 1921. Its core innovation was the use of aliphatic aldehydes (C-10, C-11, C-12) at up to 2% of the formula, a concentration unprecedented at the time, which created a diffusive, abstract floral effect that launched the entire aldehydic family in modern perfumery (Wikipedia EN “Chanel No. 5”, accessed 2026-05-27).
The name N°5 comes from the fifth sample in the brief Beaux submitted to Coco Chanel in 1920, selected for its modernity over conventional floral compositions.
Why it matters
The original formula combined aldehydes, neroli, ylang-ylang, rose de Mai and jasmine Grandiflorum from Grasse (central signature), iris, vetiver, sandalwood, vanilla, and musk tonkin (base, later replaced by synthetic musks after 1979 IFRA restrictions). Multiple reformulations followed: 1924, 1948, 1979, 1990, 2007, each driven by IFRA regulatory changes and ingredient scarcity (Osmotheque de Versailles, accessed 2026-05-27).
For the niche perfumery community, Chanel N°5 1921 functions as a historical reference point: the composition that proved abstraction and synthetic molecules could outperform naturalistic florals commercially. The original reconstructed formula is preserved at the Osmotheque de Versailles, France.
Examples
Niche compositions referencing or responding to the Chanel N°5 aldehydic legacy:
- Chanel N°5 L'Eau (Chanel, 2016, Olivier Polge): a lighter contemporary reinterpretation preserving the aldehydic floral accord.
- 22 (Chanel, 1922, Ernest Beaux): Beaux's follow-up, even more aldehydic, considered by historians the more daring of the two.
- The aldehydic family broadly: Rive Gauche (YSL, 1971), White Linen (Estee Lauder, 1978), First (Van Cleef & Arpels, 1976) all descend from the 1921 accord logic.
