CARBON DIOXIDE

Safety grade: A

Carbon dioxide is a colorless, odorless gas that's naturally present in the air we breathe. In cosmetics, it's often used in pressurized form to help dispense products from aerosol cans.

Carbon dioxide acts as a propellant in spray bottles and aerosol cans, pushing the product out so it can be applied evenly to the skin or hair.
