100% natural origin · ISO 16128

Is Fisetin natural?

Yes. Typically obtained by extracting/purifying from plant sources (e.g. Cotinus wood); a synthetic or biosynthetic route cannot be ruled out.

How we scored it

C15H10O6 flavonol; treated as an isolated extraction product, not a fragment split, but the commercial route is uncertain.
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

Commercial fisetin is generally extracted and purified from plant sources such as smoke-tree (Cotinus) wood or fruit processing residues. A chemical or fermentation-based synthesis route may also exist but could not be confirmed as minor.

In plain English

A yellow plant pigment (flavonoid) used here as a skin-conditioning colorant, normally obtained by extracting and purifying it from wood or fruit sources. The exact manufacturing route could not be fully confirmed.
