Profile
Gamma Undecalactone is curated in this catalog as a stone fruit material, with a secondary reading of creamy fruit.
On the strip it reads Peach-coconut creamy lactone (trade name Aldehyde C-14).
It is registered under CAS 104-67-6.
The catalog records an average working dose of 5% Max%, which is a starting point for a trial rather than a limit.
How it behaves
volatility index 0.49 · the baseA boiling point of 297 °C and a molecular weight of 184.28 g/mol give Gamma Undecalactone a volatility index of 0.49, which places it in the base of a composition.
It evaporates slowly and anchors the drydown, still readable on skin hours after the top notes have gone.
The index runs from 0 for a material that barely leaves the strip to 1 for one that flashes off, and it is computed from boiling point and molecular weight. Inside a real formula the surrounding materials shift where the boundaries fall, so a material can read differently there than it does here.

Questions about Gamma Undecalactone
What does Gamma Undecalactone smell like?
Gamma Undecalactone reads as stone fruit and creamy fruit, described in the catalog as Peach-coconut creamy lactone (trade name Aldehyde C-14).
Is Gamma Undecalactone a top, heart or base note?
Gamma Undecalactone sits in the base. Its volatility index of 0.49 is computed from a boiling point of 297 °C and a molecular weight of 184.28 g/mol, rather than assigned by hand. It evaporates slowly and anchors the drydown, still readable on skin hours after the top notes have gone.
How much Gamma Undecalactone should I use?
The catalog records an average working dose of 5% Max% for Gamma Undecalactone. Treat that as the starting point for a trial: the right dose depends on what else is in the formula and what you want it to do there.
What can I use instead of Gamma Undecalactone?
The closest materials in this catalog by olfactive profile and physical behaviour are Gamma Decalactone (94.9% match), Damascone Beta - Firmenich (63.7% match) and alpha-Damascone (63.5% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Gamma Undecalactone. Ranking ignores price.
What is the CAS number for Gamma Undecalactone?
