Chanel No.5 is the first perfume in the floral-aldehyde group and the first by the quantity of aldehydes in its composition (another legend says that the Ernest Beaux's assistant overdosed the aldehydes in the composition by mistake). The top notes are composed of aldehydes, bergamot, lemon, neroli and ylang-ylang, the heart of jasmine, rose, lily of the valley and iris, while the base is created of vetiver, sandalwood, vanilla, amber and patchouli.
