How we scored it

Hydrous calcium silicate mineral; calcium and silica are both 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

Produced from natural limestone (calcium) and silica/sand sources, either mined directly or synthesised from these mineral feedstocks. No petrochemical route is used.

In plain English

A mineral compound of calcium and silica used to absorb oil, bulk out powders and reduce transparency in cosmetic formulas.

CosIng definition: Calcium Silicate is a hydrous or anhydrous silicate with varying proportions of calcium oxide and silica.
