Aldehyde C14 Natural Isolate (DEXTRO)

Adam Michael has this to say “So for many years we have carried Aldehyde C14 Racemic, not actually an aldehyde of course but a lactone and better known as Gamma Undecalactone. As I have said within that product content, I don’t believe it opens as glorious as the synthetic  – of which I still am very fond of today and of which I perceive as a fantasy smelling sweet peach. My issue with the racemic aldehyde c14 natural is that the opening is somewhat flat, harsh and scratchy – more reminiscent of hairy peach skins. Yet once diluted and from the heart onwards I find it to be much more pleasant.

However what we have here is the dextro offering of aldehyde C14, 98% purity, and whilst it does cost  much more than racemic material, it also delivers the better “peach” profile throughout and ultimately represents better value for money. In pure form this is a peach-bomb and it needs to be diluted down prior to evaluation – dilutes perfectly in alcohol at 10%.

The profile is as to be expected, juicy, fruity, intense peach, and actually very reminiscent in smell form to how Iced Peach Tea drinks taste. Handle with care as this profile is deceptively powerful, saturating and long lasting – 17 hours on my skin (10% dilution) and counting.

Steffen Arctander has this to say “Practically insoluble in water, soluble in alcohol and oils. This material 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 perfumers shelf. But it is not the kind of material ordinarily sold in drum-lots. However, after the success of a new perfume (type) in the 1950s, the title material had a further increase in popularity, when numerous perfumers used it at unusually high levels along with new non-Nitro musk chemicals, in order to duplicate part of the new note in the successful perfume.

The author has yet to see a duplication which sells better than the original (in perfumes), but it must be admitted that Undecalactone drew benefit from this popularity. lt blends excellently with Nonalactone in Gardenia and Tuberose, and in many versions of lilac bases. It extends the depth of an Orangeblossom 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.

The material was originally used in Violet perfumes, so popular at the time of discovery of this Lactone (about 1900). But its most important use today is in flavors, primarily in imitation Peach, but also in many fruity types, often as a fixative for the very volatile fruit esters.

The name “Peach Aldehyde” is used stubbornly in the perfume industry, and it puzzles the chemist who knows that the material is not an aldehyde and does not have the disadvantages of an aldehyde in a composition.”
