How we scored it
Myrcene C10H16 (136) + H2O (18) = 154, matching given MW 154.25 exactly. Myrcene is made almost exclusively from turpentine-derived beta-pinene; water addition adds no petrochemical mass.
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
Manufactured by hydrating myrcene, which is obtained by pyrolysis of beta-pinene from pine-tree turpentine (a pulping by-product). No significant petrochemical route to myrcene is used commercially.
In plain English
A fragrance ingredient with a floral, woody-lavender scent. It is made by reacting myrcene, a terpene derived from pine-tree turpentine, with water.
Structure
2-methyl-6-methylideneoct-7-en-2-ol
