Science & Benefits
A highly volatile branched-chain hydrocarbon used as a propellant. It has a boiling point near room temperature, causing it to evaporate instantly upon contact with skin. This evaporation creates the 'foaming' effect in modern shave gels and cleansers. It is 100% non-comedogenic. Its fast evaporation ensures it leaves no residue that could interfere with the skin's natural oil flow.
