How we scored it
Natural hydrous magnesium silicate mineral, explicitly listed as 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
Mined from talc rock deposits, then crushed, milled and purified. No synthetic alternative is used.
In plain English
A soft mineral powder that absorbs moisture, prevents caking and adds smoothness or opacity. Mined from natural talc rock and ground fine.
CosIng definition: Talc is a powdered native, hydrous magnesium silicate sometimes containing a small portion of aluminum silicate.
