What Propane does

Pushes product out of an aerosol can
Lets sprays come out as a fine mist
Evaporates quickly, leaving little residue

Propane comes from petroleum refining and natural gas processing. It is separated, purified, and packed into aerosol cans under pressure. Cosmetic-grade propane is held to purity standards suitable for products that touch skin.

Formulators use propane because it is a gas at normal room temperature, so it creates a fine spray when the valve is pressed. It also evaporates quickly after spraying, which means the product dries fast and feels light. As it evaporates, it can give a cool, dry feel on skin or hair.

Good for

Suits aerosol sprays such as deodorants, dry shampoos and makeup removers that need a light, fast-drying mist.

Frequently asked questions

Is propane safe in cosmetics?

Propane is widely used in aerosol cosmetics and is generally well tolerated. It is flammable, so aerosol cans should be kept away from heat, open flame, and direct sun, as the label directs.

Does propane stay on my skin or hair?

Mostly no. Propane leaves the can as a gas and evaporates quickly, so it does not build up on skin or hair. The other ingredients in the product are what remain behind.
