propellantgas
A propellant gas is a gas used to propel or expel material from a container or device by providing pressure. In many consumer products, the gas is stored under high pressure in a sealed can or bottle and is released through a nozzle to move the product out. The gas can be inert or reactive with the product, and its choice depends on compatibility, safety, and performance requirements.
Common propellant gases include inert options such as nitrogen (N2), carbon dioxide (CO2), argon (Ar), and helium
Applications span a range of products, including paints, coatings, personal care items, household cleaners, and food
