Hydrofluorocarbon 152a

Safety Information

Expert Panel for Cosmetic Ingredient Safety

Scientific data supporting the safety of hydrofluorocarbon 152a as used in cosmetics and personal care products was thoroughly reviewed in 2017 by the Expert Panel for Cosmetic Ingredient Safety (Expert Panel), concluding that it is safe in the present practices of use and concentration in cosmetics.

Potential adverse effects during normal use of cosmetic spray products are unlikely due to the chemical and physical properties of this spray propellant ingredient. Hydrofluorocarbon 152a is a largely inert gas that rapidly volatilizes and disperses upon application. Therefore, if it is incidentally inhaled during use and absorbed into the bloodstream, it is quickly cleared from the body through exhalation. 

Extensive short- and long-term inhalation safety studies, conducted at concentrations significantly higher than those consumers would ever be exposed to during cosmetic use, indicate that the use of hydrofluorocarbon 152a in cosmetic spray products will not cause adverse health effects when used as directed. 

Hydrofluorocarbon 152a may be used without restrictions in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.


Hydrofluorocarbon 152a

What Is It?

Hydrofluorocarbon 152a (1,1-difluoroethane), commonly known as HFC-152a, is a gas that functions as a propellant in personal care products.

Why Is It Used?

Hydrofluorocarbon 152a is used as propellant in hair spray and spray deodorants. It is also used in foams, mousses and commercial aerosol foam products (e.g., hair styling and skin conditioning mousses).

Scientific Facts

Hydrofluorocarbon 152a is an aerosol propellant that does not contain chlorine atoms. In states with regulations aimed at limiting Volatile Organic Compound (VOC) emissions, it is a preferred propellant in a wide range of consumer products because of its low Global Warming Potential and the fact that it does not contribute to stratospheric ozone depletion like chlorofluorocarbons or other chlorinated hydrocarbons.
