How we scored it

Mineral salt (potassium + carbonate, both natural-origin) → 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 from mined potassium chloride (potash) or brine, converted to the carbonate salt. No petrochemical route exists for this inorganic mineral.

In plain English

A mineral salt, historically known as potash, used to gently adjust and buffer a formula's pH. Comes from mined potassium-containing minerals or brine deposits.
