Aerosol products are containers that release a fine mist or spray of liquid when a valve is pressed. They are commonly used for various purposes, including personal care items like deodorants and hair sprays, as well as household cleaners and air fresheners. The contents are typically stored under pressure, allowing for a controlled and even distribution. These products often contain propellants, which help to expel the liquid from the container. Common propellants include hydrocarbons and compressed gases. While convenient, aerosol products can have environmental impacts, leading to regulations aimed at reducing harmful emissions and promoting safer alternatives.
