How we scored it

Li2CO3 mineral salt; alkali-metal ion and carbonate are both natural-origin counter-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

Extracted from lithium-bearing brines or spodumene ore and precipitated as the carbonate salt. This is the only commercial route.

In plain English

A mineral salt used to adjust pH and in hair-waving products. Mined from lithium-rich brines or rock ore, then purified into carbonate form.
