Profile
Helvetolide is curated in this catalog as a musky material, with a secondary reading of crisp fruit.
On the strip it reads pear fruity musk powdery.
It is registered under CAS 141773-73-1.
The catalog records an average working dose of 10% Max%, which is a starting point for a trial rather than a limit.
How it behaves
volatility index 0.40 · the baseA boiling point of 290 °C and a molecular weight of 284.4 g/mol give Helvetolide a volatility index of 0.40, 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 Helvetolide
What does Helvetolide smell like?
Helvetolide reads as musky and crisp fruit, described in the catalog as pear fruity musk powdery.
Is Helvetolide a top, heart or base note?
Helvetolide sits in the base. Its volatility index of 0.40 is computed from a boiling point of 290 °C and a molecular weight of 284.4 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 Helvetolide should I use?
The catalog records an average working dose of 10% Max% for Helvetolide. 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 Helvetolide?
The closest materials in this catalog by olfactive profile and physical behaviour are Galaxolide (76.9% match), Exaltolide (76.5% match) and Exaltolide Total (76.5% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Helvetolide. Ranking ignores price.
What is the CAS number for Helvetolide?
