How we scored it
Inorganic mineral salt: sodium and phosphate ions both natural-origin per this site's method. 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
Manufactured from mined phosphate rock and a sodium source via neutralisation. The supplied formula/MW appear inconsistent with the stated CAS (trisodium phosphate), but this does not affect the mineral classification.
In plain English
A mineral salt used to buffer pH and control odour in cosmetics. It comes from processing mined phosphate rock, similar to ingredients in food and water treatment.
CosIng definition: Sodium Phosphate is the inorganic salt that conforms to the formula
Structure
sodium phosphate
