Is Calcium Chloride natural? NOI 1.00

Q: Is Calcium Chloride natural?

Calcium Chloride has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Simple inorganic salt, mined or brine-derived; no organic content. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

CaCl2: Ca2+ and Cl- both mineral-origin ions → 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

Obtained from natural brines or as a by-product of mineral (limestone) processing. This is the standard commercial source.

In plain English

A mineral salt used to add astringency and control viscosity. It's sourced from natural brine or limestone processing, not from petrochemicals.
