Is Ferric Chloride natural? NOI 1.00

Q: Is Ferric Chloride natural?

Ferric Chloride has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Simple inorganic iron chloride salt, mineral-origin under ISO 16128. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

FeCl3 inorganic mineral salt; iron and chloride are both mineral-origin.

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

Ferric chloride is produced from iron ore or scrap iron reacted with hydrochloric acid or chlorine, both mineral-origin processes.

In plain English

A mineral salt of iron used as an astringent in cosmetics. It is produced from iron ore, a naturally mined mineral.
