Is Zinc Peroxide natural?

Yes. Zinc is a natural mineral-origin metal ion; the peroxide oxygen carries no petrochemical mass; classed with other mineral oxides.

CAS1314-22-3
FunctionOxidising
FeedstockManufactured by reacting a zinc salt or zinc…

How we scored it

Zn2+ (metal ion, mineral) + peroxide O2^2- (elemental oxygen); treated as mineral-origin oxidising salt, same convention as zinc 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 a zinc salt or zinc oxide with hydrogen peroxide. Both zinc and oxygen are mineral/elemental in origin, so the compound is classed as natural origin.

In plain English

An inorganic zinc compound made by reacting a zinc salt with hydrogen peroxide. Used as an oxidising agent in some cosmetic formulations.
