Personal aerosols and toiletries
Personal Aerosols fall into two categories – "Medicinal or toiletry articles" and "Sporting or Home Use".
If the aerosol is flammable, or contain a propellant that is a flammable gas (the container will have either a red diamond or alternatively a pictogram with the word "flammable"), then passengers may only take those that would fall into the category of "medicinal or toiletry article". Examples are hair sprays, colognes, deodorants, shaving foam, personal disinfectant etc. These aerosols may be carried in carry-on or checked baggage, although there are limitations for International flights for Liquids, Aerosols and Gels.
If the aerosol is not flammable (it will have a green diamond on the back of the container), then passengers may take aerosols that would fall into the category of "sporting or home use". Examples are air fresheners, fly sprays, furniture cleaners etc. Aerosols in the category of sporting or home use may only be taken in checked-in baggage.
Non-flammable aerosols in the "medicinal or toiletry article" category may be carried in the cabin.
The total net quantity of medicinal and toiletry articles and aerosols for sporting or home use must not exceed 2 Kg or 2 Litres and the net quantity of each single article must not exceed 0.5 Kg or 0.5 Litre. Release valves on aerosols must be protected by a cap or other means to prevent inadvertent release of the contents.
