Profile
Undecanal is curated in this catalog as an aldehydic material, with a secondary reading of soapy.
On the strip it reads waxy clean soapy aldehyde.
It is registered under CAS 112-44-7.
The catalog records an average working dose of 1% Max%, which is a starting point for a trial rather than a limit.
How it behaves
volatility index 0.63 · the openingA boiling point of 223 °C and a molecular weight of 170.29 g/mol give Undecanal a volatility index of 0.63, which places it in the opening of a composition.
It leaves the strip early and does its work in the first minutes, before the heart arrives.
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 Undecanal
What does Undecanal smell like?
Undecanal reads as aldehydic and soapy, described in the catalog as waxy clean soapy aldehyde.
Is Undecanal a top, heart or base note?
Undecanal sits in the opening. Its volatility index of 0.63 is computed from a boiling point of 223 °C and a molecular weight of 170.29 g/mol, rather than assigned by hand. It leaves the strip early and does its work in the first minutes, before the heart arrives.
How much Undecanal should I use?
The catalog records an average working dose of 1% Max% for Undecanal. 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 Undecanal?
The closest materials in this catalog by olfactive profile and physical behaviour are Aldehyde C-12 MNA (94% match), Aldehyde C-10 (decanal) (80.5% match) and Aldehyde C-11 Undecylenic (80.3% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Undecanal. Ranking ignores price.
