How we scored it
Composed solely of silicon, calcium, sodium and phosphorus oxides (a bioactive glass); all fragments are mineral; no organic or petrochemical mass present.
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
Manufactured by fusing mineral oxide feedstocks (silica sand, calcium and sodium sources, phosphate) into a glass, then milling to a powder. No organic alternative route applies.
In plain English
A fine mineral glass powder used in toothpaste to help remineralise teeth and reduce sensitivity. It is made by fusing together silica, calcium, sodium and phosphate, all mineral ingredients.
CosIng definition: Calcium Sodium Phosphosilicate is a powder consisting of oxides of silicon, calcium, sodium and phosphorus
