How we scored it

Sodium aluminum sulfosilicate (ultramarine) is a fully inorganic mineral pigment; all atoms (Na, Al, S, Si, O) count as natural origin.
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

CI 77007 (ultramarine) is manufactured by calcining kaolin clay, sodium carbonate and sulfur sources at high temperature. No organic/petrochemical feedstock is involved.

In plain English

CI 77007 (ultramarine) is a mineral pigment made from sodium, aluminium and sulfur-containing silicates. Used to add blue/violet colour to cosmetics.

CosIng definition: CI 77007 is classed chemically as an inorganic colour. It is a synthetic pigment composed of complex sodium aluminum sulfosilicates.
