How we scored it
Camphene is manufactured by acid-catalysed isomerisation of alpha-pinene from turpentine; the carbon skeleton stays entirely pine-terpene derived, 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Camphene is produced industrially by isomerising alpha-pinene, obtained from pine-tree turpentine (a paper-industry by-product). No petrochemical route is commercially significant.
In plain English
A pine-scented aroma ingredient. It's produced by rearranging pinene, a terpene obtained from pine tree resin (turpentine), without adding any petroleum-based material.
CosIng definition: Camphene is the organic compound that conforms to the formula
