The catalog records an average working dose of 0.1% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.89 · the opening

A boiling point of 94.5 °C and a molecular weight of 138.21 g/mol give 2-trans-6-cis-Nonadienal a volatility index of 0.89, 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.
