Chloropentafluoroethane

Food additives Europe numbers: E945 
 

Chloropentafluoroethane (CPFE) isn't typically considered a food excipient or additive. Here's why:

Function:

• CPFE belongs to a class of chemicals called chlorofluorocarbons (CFCs). Their main historical use was as refrigerants and propellants, but their production and use have been largely phased out due to environmental concerns.

Not Used in Food:

• CPFE doesn't have any approved applications in food or food processing. Food safety regulations and agencies like the US Food and Drug Administration (FDA) have strict guidelines for additives, and CPFE wouldn't meet safety requirements for food consumption.

Potential Past Use (Unlikely):

• In the very distant past (prior to the 1970s), some CFCs, including some forms of chloropentafluoroethane, might have been used as propellants in aerosol food products like whipped cream. However, this practice was discontinued due to environmental concerns.

Safer Alternatives:

• Modern food processing relies on safe and effective alternatives for refrigeration and other processes that CFCs were once used for.
