Profile

alpha-Methyl Ionone is curated in this catalog as a powdery material, with a secondary reading of woody.

On the strip it reads sweet powdery violet woody.

It is registered under CAS 127-43-5.

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 0.57 · the heart

A boiling point of 240 °C and a molecular weight of 206.32 g/mol give alpha-Methyl Ionone a volatility index of 0.57, which places it in the heart of a composition.

It arrives as the opening thins and holds the centre of a composition, which is where most of the character of a fragrance is decided.

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 alpha-Methyl Ionone

What does alpha-Methyl Ionone smell like?

alpha-Methyl Ionone reads as powdery and woody, described in the catalog as sweet powdery violet woody.

Is alpha-Methyl Ionone a top, heart or base note?

alpha-Methyl Ionone sits in the heart. Its volatility index of 0.57 is computed from a boiling point of 240 °C and a molecular weight of 206.32 g/mol, rather than assigned by hand. It arrives as the opening thins and holds the centre of a composition, which is where most of the character of a fragrance is decided.

How much alpha-Methyl Ionone should I use?

The catalog records an average working dose of 5% Max% for alpha-Methyl Ionone. 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 alpha-Methyl Ionone?

The closest materials in this catalog by olfactive profile and physical behaviour are Dihydro Ionone Beta (Givaudan) (100% match), Ionone Alpha (IFF) (100% match) and Isoraldeine 70 - Givaudan (100% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like alpha-Methyl Ionone. Ranking ignores price.

What is the CAS number for alpha-Methyl Ionone?

alpha-Methyl Ionone is registered under CAS 127-43-5 in this catalog.
