How we scored it
Formula = caryophyllene (C15H24, natural sesquiterpene from clove/copaiba oil) plus one oxidant-derived oxygen; added O is not petrochemical carbon, per oleic-acid ozonolysis convention = 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
Produced by isolating beta-caryophyllene from clove bud or copaiba oil and then oxidising it. The oxidising agent contributes only an oxygen atom, not petrochemical carbon.
In plain English
A fragrance ingredient derived from a natural compound found in clove and copaiba oils, lightly oxidised during processing. Used to add scent to cosmetic products.
