Is Lithium Hydroxide natural? NOI 1.00

Q: Is Lithium Hydroxide natural?

Lithium Hydroxide has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Lithium is mined from ore or brine, like other alkali/alkaline-earth metals ISO 16128 treats as mineral/natural origin. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Single mineral hydroxide compound; Li and OH both mineral-origin → 1.0 (analogous to other alkali-metal hydroxides).

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 lithium-bearing brine or spodumene ore by extraction and processing. No petrochemical route exists for this mineral compound.

In plain English

A mineral-derived pH-adjusting ingredient made from lithium, a metal mined from ore or salt brines. It's used in small amounts to balance the acidity of formulas.
