The ingredient narratives reshaping clean beauty.
Isobutane / Propane
aka butane/isobutane/propane propellant · LPG propellant · aerosol propellant blend
Hydrocarbon aerosol propellant blend used in foam shampoo and dry shampoo aerosol formats. The standard clean alternative to CFC propellants.
- Aerosol propellant for foam formation
- Clean alternative to CFC propellants
- Enables mousse and foam textures
- Odourless at use concentrations
- High purity grades available
- Foam shampoos
- Mousse styling products
- Dry shampoo aerosols
- Aerosol sunscreens
- Whipped body products
Functions in pressurised aerosol cans. No skin-active function — propellant role only. Flammable — fire-safety labelling required on packaging.
Highly flammable — appropriate storage and use warnings required. LPG-derived; fossil fuel origin may be flagged by ultra-sustainable brands exploring compressed air alternatives.
Generally accepted in clean beauty. Not present on clean ingredient ban lists. Fossil fuel origin occasionally noted but no established health concern at cosmetic use.
