How we scored it
Ca2+ (metal ion, mineral) + peroxide O2^2- (elemental oxygen, formula CaO2 72.08 Da given); mineral-origin oxidising salt, same convention as calcium oxide → 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 by reacting calcium hydroxide with hydrogen peroxide. Both calcium and oxygen are mineral/elemental in origin, so the compound is classed as natural origin.
In plain English
An inorganic calcium compound made by reacting a calcium salt with hydrogen peroxide. Used as an oxidising agent in some cosmetic and oral care formulations.
Structure
calcium peroxide
