How we scored it

C13H18O, 190.28 Da: 4-ethylphenyl ring from petrochemical benzene and ethylene; 2,2-dimethylpropanal chain from isobutyraldehyde (propylene). Natural mass 0 / 190.28 = 0.00.
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

Dominant route: a 4-ethylbenzyl halide (from ethylbenzene) is condensed with isobutyraldehyde, all petrochemical. No isolation from plants and no terpene-based route is known.

In plain English

A synthetic fragrance ingredient with a fresh, watery, floral scent in the lily-of-the-valley and cyclamen family. It is made in a chemical plant from petrochemical benzene-derived building blocks, not extracted from plants.
