Profile

Hexanal is curated in this catalog as a green material, with a secondary reading of fatty.

On the strip it reads green leafy hay aldehydic.

It is registered under CAS 66-25-1.

The catalog records an average working dose of 0.5% Max In Concentrate%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.87 · the opening

A boiling point of 127.8 °C and a molecular weight of 100.16 g/mol give Hexanal a volatility index of 0.87, 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 Hexanal

What does Hexanal smell like?

Hexanal reads as green and fatty, described in the catalog as green leafy hay aldehydic.

Is Hexanal a top, heart or base note?

Hexanal sits in the opening. Its volatility index of 0.87 is computed from a boiling point of 127.8 °C and a molecular weight of 100.16 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 Hexanal should I use?

The catalog records an average working dose of 0.5% Max In Concentrate% for Hexanal. 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 Hexanal?

The closest materials in this catalog by olfactive profile and physical behaviour are cis-3-Hexenol (76.8% match), Herboxane (Givaudan) (69.8% match) and cis-3-Hexenyl Acetate (69.2% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Hexanal. Ranking ignores price.

What is the CAS number for Hexanal?
