Profile

trans-Anethole is curated in this catalog as a warm spice material, with a secondary reading of anisic.

On the strip it reads sweet anise licorice.

It is registered under CAS 4180-23-8.

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 opening

A boiling point of 235.5 °C and a molecular weight of 148.205 g/mol give trans-Anethole 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 trans-Anethole

What does trans-Anethole smell like?

trans-Anethole reads as warm spice and anisic, described in the catalog as sweet anise licorice.

Is trans-Anethole a top, heart or base note?

trans-Anethole sits in the opening. Its volatility index of 0.63 is computed from a boiling point of 235.5 °C and a molecular weight of 148.205 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 trans-Anethole should I use?

The catalog records an average working dose of 1% Max% for trans-Anethole. 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 trans-Anethole?

The closest materials in this catalog by olfactive profile and physical behaviour are Estragole (100% match), Cinnamyl Alcohol (77.7% match) and Acetanisole Crystals (74.5% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like trans-Anethole. Ranking ignores price.
