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. See also gamma-Decalactone, gamma-Dodecalactone, delta-decalactone, Nectarate and Nectaryl, for alternative peach-notes.
Arctander has quite a bit to say about gamma-Undecalactone, including: "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 perfumer’s 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.”

Each entry contains a short list of scent notes with occasionally other short commentary to assist those who may not have encountered the material previously to decide whether it is of interest: I recommend you make your own assessment of each and every perfumery material you use however.
After pricing, quantity options and other basic details scroll down for narative descriptions: these are intended to assit interested readers as well as potential purchasers to assess the uses and potential of the material in question.
Many of the descriptions contain quotations from the manufacturer of the product and in addition I have quoted fairly extensively from Arctander[1] and from Arcadi Boix Camps[2] – both independent writers and both highly experienced perfumers.
There are also some quotes from Bedoukian[3] where details of the chemistry of a material are significant and from Scent & Chemistry[4] the authors of which have taken an analytical approach to the art of perfumery that is unusual and very useful. Quotations have been included from the extremely useful teaching books by Calkin & Jellinek[5] and Curtis & Williams[6] and Surburg and Panten [7] as well.
Anything not identified as a quotation is my own opinion of the material in question and it’s uses, but I am grateful to many other sources and perfumers as well as the expert authors named here. Please note that these descriptions are copyright of the author and, other than properly achnowledged fair use quoations as defined in English Law, republication in any form is not permitted.

A quick note about spellings: this website is primarily written in British English - it is after all written by an English Perfumer - however most of the authors mentioned here and many of the manufacturers were writing for American audiences and published using American English: where that is the case I have, as far as possible, preserved the spelling used in the source material. As a result there may be inconsistencies on any given page, but that seemed to me better than arbitrarily changing material in the process of quotation.
We’ve recently had a change of policy - and bought some new containers - so now all ingredients are sold by weight whether they are solids or liquids. Only the 10ml and 5ml sizes incorporated in kits, and a few inexpensive materials such as solvents, are still done by volume. Even the 5ml and 10ml sizes will now be filled to contain 5g or 10g regardless of whether the material is solid or liquid.
Liquids up to 10g in glass bottles (where the fill level may vary as illustrated above), 30g and 50g in HDPE Plastic.
Those materials available in 1Kg are normally supplied in aluminium flasks similar to those used for the 500g size, though we do supply a few materials in HDPE bottles as well.
Finally please note that, with some 500 different materials and so many size options we don’t hold ready-to-sell stocks: when you buy perfumery ingredients we will prepare them to order for you. This means that large orders can sometimes take a few days to prepare and also that we don’t offer refunds on ingredients, unless of course there is a fault of some kind.
