How we scored it
CosIng: mineral, aluminium beryllium silicate (beryl). Supplied formula C18H12Cl2N2O/CAS 12415-33-7 matches boscalid fungicide (likely trade-name collision with the 'Emerald' turf fungicide), not this mineral — disregarded per CosIng authority. Mineral → 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 aluminium beryllium silicate (beryl-family) gemstone, milled for cosmetic abrasive use. No synthetic manufacturing route is used commercially; the ingredient is sourced by mining.
In plain English
A ground natural gemstone mineral used as a gentle abrasive in some cosmetic powders and scrubs. It comes directly from mined mineral rock, not a laboratory.
CosIng definition: Emerald is a mineral consisting chiefly of aluminum beryllium silicate.
