Is Calcium Titanate natural? NOI 1.00

Q: Is Calcium Titanate natural?

Calcium Titanate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Calcium, titanium and oxygen form a mineral metal oxide (perovskite), which ISO 16128 treats as natural origin like titanium dioxide. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

CaTiO3 135.94 Da: Ca 40.08 + Ti 47.87 + O3 48.00, all mineral. 135.94 / 135.94 = 1.00.

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

Dominant route is high-temperature solid-state reaction of calcium carbonate or oxide with titanium dioxide, both mineral. The natural mineral perovskite is the same compound.

In plain English

A white mineral powder, calcium titanium oxide, used as a skin-protecting powder in cosmetics. It is made by firing calcium carbonate or oxide with titanium dioxide at high temperature, and also occurs naturally as the mineral perovskite.
