How it behaves

volatility index 0.52 · the heart

A boiling point of 301 °C and a molecular weight of 146.14 g/mol give Coumarin (crystal powder) a volatility index of 0.52, 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.
