Is Cyclopentadecanone natural?

No. Occurs only in trace natural amounts; essentially all commercial cyclopentadecanone is synthesized from petrochemical cyclic precursors via classical large-ring ketone synthesis.

How we scored it

Classic synthetic musk ketone ('Normuscone'); commercial supply made by ring-expansion synthesis from petrochemical precursors, not extraction.
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 via classical large-ring ketone synthesis (e.g. acyloin or Thorpe-Ziegler condensation) from petrochemical-derived long-chain precursors. Natural occurrence is trace and not commercially harvested.

In plain English

A musk-scented fragrance ingredient, nicknamed 'normuscone'. Made synthetically in a lab; only trace amounts occur in a few natural sources, not enough to supply the market.

CosIng definition: Normuscone
