What it is
A hydrocarbon gas used strictly as a propellant in aerosol food sprays.
How it is used in food
An efficient, cheap propellant for aerosol food sprays such as cooking oils and spray creams; unlike older chlorofluorocarbons it does not damage the ozone layer.
Commonly found in- Cooking oil sprays
- Whipped cream cans
Health and safety
Evaporates instantly upon leaving the can; no residue remains in the food.
EFSA re-evaluated propane, butane and isobutane (E944/E943a/E943b) and concluded there is no safety concern for their use as propellants, since residual levels in food are negligible.
