Isobutane is a propellant used to dispense a product from a container. It is often used in concert with other propellants, such as butane and propane. While isobutane is commonly known for its use as a fuel, for example, for camp stoves, when used as a propellant, its energy comes from being compressed in a can rather than from being lit or heated.

Ethanol is a solubilizer that can also be found in makeup, lotions, and hair care products. It works by dissolving the ingredients of a product to help them mix together better. It also can act as a carrier or as a cleaning agent that helps dissolve soils. Ethanol is the same alcohol that's found in alcoholic beverages, but in consumer products it is used in very small amounts to make the product work better.

Propane is a propellant used to dispense a product from a container. It is often used in concert with other propellants, such as butane and isobutane. While propane is commonly known for its use as a fuel, for example, for grills and portable stoves, when used as a propellant, its energy comes from being compressed in a can rather than from being lit or heated.
