An aerosol spray is a pressurized dispenser that releases a liquid or semi-liquid substance as a fine mist or spray. It consists of a canister containing both the product and a propellant gas. When the nozzle is pressed, the propellant forces the product out through a small valve, dispersing it evenly. Aerosol sprays are widely used in products like air fresheners, deodorants, paints, and insect repellents, offering a convenient and controlled way to apply products. Modern aerosol sprays often use environmentally friendly propellants and recyclable canisters, balancing consumer convenience with sustainability.
