Non-toiletry, some electronics cleaners, whipped cream
Nonflammable aerosols that do not qualify for the medicinal/toiletry article exception may be carried in checked baggage only.
For transportation purposes, an "aerosol" is a product that uses compressed gas to expel another material (liquid, powder, creams, etc.). Canisters containing compressed gases that ARE the product, (e.g., canned oxygen, refrigerant gases, compressed air for cleaning electronics) do not qualify as an aerosol and cannot use this exception.
Quantity limits: Included in, not in addition to, the quantity limits for medicinal and toiletry articles: The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
There are very few nonflammable aerosols. Check to make sure the container indicates it is nonflammable.
Regulation that allows it: 49 CFR 175.10(a)(1)(ii)
