NOPOL Usage And Synthesis

Chemical Properties

10-Hydroxymethylene-2-pinene has a mild, woody, camphoraceous odor.

Occurrence

Reported found in carrots

Uses

Nopol is by and large confined to woody and piney fragrance types, in which it may be the chief ingredient or "carrier". But its own odor contribution is very limited, and the title material will ruin almost any floral note if the Nopol is used at higher levels of concentration.

Preparation

Nopol is produced by condensation of beta-Pinene with Formaldehyde under pressure (= at elevated temperature).
