Profile

alpha-Pinene is curated in this catalog as a piney material, with a secondary reading of coniferous.

On the strip it reads sharp pine terpene.

It is registered under CAS 80-56-8.

The catalog records an average working dose of 10% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.78 · the opening

A boiling point of 156.2 °C and a molecular weight of 136.23 g/mol give alpha-Pinene a volatility index of 0.78, 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 alpha-Pinene

What does alpha-Pinene smell like?

alpha-Pinene reads as piney and coniferous, described in the catalog as sharp pine terpene.

Is alpha-Pinene a top, heart or base note?

alpha-Pinene sits in the opening. Its volatility index of 0.78 is computed from a boiling point of 156.2 °C and a molecular weight of 136.23 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 alpha-Pinene should I use?

The catalog records an average working dose of 10% Max% for alpha-Pinene. 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-Pinene?

The closest materials in this catalog by olfactive profile and physical behaviour are beta-Pinene (100% match), Camphene (84.3% match) and Pine Needle EO (84.1% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like alpha-Pinene. Ranking ignores price.

What is the CAS number for alpha-Pinene?

alpha-Pinene is registered under CAS 80-56-8 in this catalog.
