Aldehyde C14 (Gamma-Undecalactone)

Aldehyde C14 (Gamma-Undecalactone)

CAS: 104-67-6

One of the oldest peach-y notes in perfumery, this isn’t really an aldehyde at all but a lactone, despite the commonly mis-applied name. A very powerful material also reminiscent of apricot it is widely used in classical perfumery.  

Aldehyde C14 is widely used, although in minute amounts, in perfume compositions. In order of frequency in use, it ranks very high among the materials on the perfumer’s shelf. But it is not the kind of material ordinarily sold in drum-lots.

lt blends excellently with Nonalactone (Aldehyde C18) in Gardenia and Tuberose, and in many versions of Lilac bases. It extends the depth of an Orange Blossom often too harsh with conventional materials, and it is a frequent component of Honeysuckle, etc. Concentrations far below 1% are effective, and it is at times possible to ruin a fragrance with 0.1 or 0.2% of the title material, just as well as it is possible to double the floral sweetness and depth of another fragrance with that amount of Undecalactone. 

Uses: The material was originally used in Violet perfumes but its most important use today is in flavours, primarily in imitation Peach, but also in many fruity types, often as a fixative for the very volatile fruit esters.
