Is Carbon Dioxide natural?

Yes. Elemental inorganic gas recovered from fermentation or atmospheric sources by physical capture, not built from petrochemical carbon.

INCI nameCarbon Dioxide

FormulaCO2 · 44.009 Da
FunctionPropellant
FeedstockCosmetic-grade CO2 is typically captured as a byproduct…

How we scored it

Single inorganic gas, CO2; captured and compressed, not synthesised from petrochemical feedstock, so all 44.01 Da is natural-origin.
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

Cosmetic-grade CO2 is typically captured as a byproduct of fermentation or from natural underground and atmospheric sources, then compressed and purified. No chemical synthesis step introduces petrochemical mass.

In plain English

A natural gas used to propel product out of aerosol cans. It's simply captured and compressed, most often from fermentation byproduct streams, rather than being chemically manufactured.
