Description and usage notes:
A very useful saturated aliphatic aldehyde: less citrus and more rose with a waxy-cucumber element that is very fresh and clean in the right dilution, it is used in high dilution and commonly in combination with other aldehydes.
Arctander says this of it: “This aldehyde is used very extensively, but also very sparingly in volume, in perfume formulations. Trace amounts, often less than 0.1 %, are used in Rose, Lily, Peony, Orris, Geranium, Citrus, Orangeblossom, Jasmin, Tuberose, Opopanax and many other fragrance types, The aldehyde will supply very natural ‘flower-wax’ or ‘petal’-notes, and give tremendous ‘lift’ to a perfume. It often forms part of an ‘aldehydic base’ which in turn may form part of a topnote composition.”
According to Bedoukian this aldehyde is known to occur in twenty or so essential oils and he says that “While it is also an important constituent of citrus oils, its discovery in rose oil in 1900 drew attention to the usefulness of aldehydes in perfumes”. He also tells us that it has a “pleasant, fatty, rose-type odour which is very desirable in light floral compositions. Because of its relative volatility, only small quantities can be used in formulations.”
