Non Chlorofluorocarbon

Non-chlorofluorocarbon (non-CFC) propellants are gases used in aerosol products. They replaced chlorofluorocarbons (CFCs) after CFCs were found to harm the Earth's ozone layer. Non-CFC propellants are typically hydrocarbons like propane, butane, or isobutane, or compressed gases like nitrogen or carbon dioxide.

Manufacturers use non-CFCs to push products out of aerosol cans, such as cooking sprays, hairsprays, and cleaning products. In cooking sprays, they help create a fine mist that evenly coats pans and cooking surfaces, preventing food from sticking. They are chosen for their ability to create a consistent spray pattern and for their safety profile.

Non-CFC propellants like hydrocarbons are generally considered safe for use in food products by the FDA when used as intended. They are not GRAS (Generally Recognized As Safe) or approved additives in the same way as many other food ingredients, but their use as propellants in food contact applications is regulated. JECFA and EFSA have evaluated various propellant gases, but specific evaluations for 'non-CFC propellants' as a broad category are not typically found. At typical levels of exposure from food products, these propellants are not associated with significant health concerns.
