Nitrogen ●
TL;DR. This ingredient is used mainly as an inert propellant, pressurizing gas, or headspace blanket in aerosols, foams, and air-sensitive formulas. It helps dispense product and can reduce oxygen exposure in packaging.
What does Nitrogen do in a cosmetic formula?
This ingredient is used mainly as an inert propellant, pressurizing gas, or headspace blanket in aerosols, foams, and air-sensitive formulas. It helps dispense product and can reduce oxygen exposure in packaging.
Is Nitrogen clean?
It is generally unproblematic in clean-beauty frameworks because it is non-fragrant, non-sensitizing, and not associated with common restricted-list concerns. Skin irritation is not expected from normal cosmetic use because it does not meaningfully react with skin or formula components.
Is Nitrogen sustainable?
This material is commonly obtained from air separation, so the feedstock is abundant, but production requires energy for compression and purification. It does not bioaccumulate and returns to the atmosphere after use.
Is Nitrogen COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when used in its simple gaseous form as a physically processed non-agricultural material. From a Green Chemistry view, it scores well for low reactivity and minimal residue, with energy use during separation and compression as the main caveat.
How does Nitrogen work chemically?
The molecule is a small, nonpolar diatomic gas with very low chemical reactivity under normal cosmetic conditions. It is typically used quantity sufficient for package pressure or headspace control, is not pH-active, and can help limit oxidation by displacing oxygen in the container.
